Individual and Household Level Risk Factors Associated with Malaria in Mutasa District, Zimbabwe: a Serial Cross-Sectional Study

Mufaro Kanyangarara and her PhD thesis adviser, Luke Mullany of the Johns Hopkins Bloomberg School of Public Health Department of International Health, have been looking into the challenges of controlling and eventually eliminating malaria in a multi-country context in southern Africa. We are sharing abstracts from her pioneering work including the following which explores risk factors on the Zimbabwe-Mozambique order.

Background: Malaria constitutes a major public health problem in Zimbabwe, particularly in theMAP 2000 and 2015 S Africa north and east bordering Zambia and Mozambique. In Manicaland Province in eastern Zimbabwe, malaria transmission is seasonal and unstable. As a result of intensive scale up of malaria interventions, malaria control was successful in Manicaland Province. However, over the past decade, Manicaland Province has reported increased malaria transmission, and the resurgence of malaria in this region has been attributed to limited funding, drug resistance and insecticide resistance. One of the worst affected districts is Mutasa District. The aim of the study was to identify malaria risk factors at the individual and household levels to better understand what is driving factors associated with malaria and consequently enhance malaria control in eastern Zimbabwe.

Methods: Between October 2012 and September 2014, individual demographic data and household characteristics were collected from cross-sectional surveys of 1,116 individuals residing in 316 households in Mutasa District. Factors characterizing the surrounding environment were obtained from remote sensing data. Factors associated with malaria (measured by rapid diagnostic test [RDT]) were identified through univariate and multivariate multilevel logistic regression models.

Results: A total of 74 (6.4%) participants were RDT positive. Parasite prevalence differed by season (10.4% rainy and 2.9% dry, OR 4.52, 95% CI 2.11-9.69). Sleeping under a bednet showed a protective effect against malaria (OR 0.54, 95% CI 0.29-1.00) despite pyrethroid resistance. The household level risk factors protective against malaria were household density (OR 0.89, 95% CI 0.87-0.97) and increasing distance from the border with Mozambique (OR 0.86, 95% CI 0.76-0.97). Increased malaria risk was associated with recent indoor residual spraying (OR 2.30, 95% CI 1.16-4.56).

Conclusions: Malaria risk was concentrated in areas located at a lower household density and in closer proximity to the Mozambique border. Malaria control in these “high risk” areas may need to be enhanced. These findings underscore the need for strong cross-border malaria control initiatives to complement country specific interventions.

Malaria Status in the 2014-15 Rwanda Demographic and Health Survey

Rwanda is experiencing low and very low levels of malaria test positivity rates, thought there are a few districts near the borders with Uganda, Tanzania and Burundi that have relatively higher transmission. Overall the country is strategizing how to move toward the pre-elimination phase on the pathway to malaria elimination. This is defined as a test positivity rate of less than 5% during the high transmission season.

DHS 2010 Malaria Prevalence in Children 6-59 MonthsIt is important to distinguish between test positivity rate and prevalence rate. The most recent survey report that gives prevalence is the DHS 2010 with a rate of 1.4% in children below 5 years of age and 0.7% among women of reproductive age. During 2010 the health management information system shows that among those tested (microscopy or RDT) for malaria, 24% were positive. The population for test positivity reports is a much smaller group that is already suspected of having malaria. That said, 24% or the 2013 rate of 29% is still far from the 5% cut-off for pre-elimination status.

Rwanda still maintains a policy of universal coverage with insecticide treated nets (ITNs). Rwanda also has a policy that every pregnant woman should receive an ITN during her first antenatal care visit. Ideally in order to reach pre-elimination status, a country needs to sustain high coverage of malaria prevention and treatment interventions at an 80% level for several years.

The newly released preliminary results of the 2014-15 DHS provide an opportunity to examine achievements. The 2014-15 DHS found that 81% of households had at least one ITN, while 43% had achieved the universal coverage target of one ITN per two household members. These numbers remain basically unchanged from the 2013 Malaria Information Survey (83% and 43%), while the 2010 DHS found 82% of households had a net, but did not report on the indicator of one net per two people. In short, it appears that coverage levels have been maintained at a certain level.

DSCN7129a pregnant women get ITNs when register for ANC RwandaDHS 2014-15 shows that 99% of pregnant women in Rwanda received antenatal care from a skilled provider. That means that basically all pregnant women should have received an ITN. 73% of pregnant women had slept under an ITN the night before they were surveyed, while 88% of all women of reproductive age slept under a net. 68% of children below the age of five years slept under an ITN the night before their household was surveyed, while 80% who lived in households that owned an ITN did so.

Indoor Residual Spraying (IRS) is focused on certain high transmission/burden districts. The preliminary 2014-15 DHS does not report on this and the 2013 MIS reports broadly by region, hence one sees coverage reports for IRS in the east (22%) and south (16%), where there is greater malaria burden, but this cannot be linked to specific districts that may have been targeted.

Rwanda also has a policy that all suspected malaria cases should be tested, whether with microscopy in health centers or rapid diagnostic tests by village health workers. It is only those persons testing positive for malaria who are supposed to be given malaria medicine.

DHS shows that 1439 children below five years of age (or 19% of the total) had fever in the two weeks prior to the survey. Of these 36% reported having a blood test performed, and 11% of those with fever received the approved artemisinin-based combination (ACT) therapy drug. The report does not indicate the actual testDSCN7282 results of those receiving ACT.

As Rwanda strategized toward reaching malaria pre-elimination status it can consider ways of enhancing ITN use, not only among vulnerable groups like small children and pregnant women, but all members of the household. As prevalence drops, so does acquired immunity, putting adults at greater risk.

The universal coverage target of at least 1 net for every two people in a household must be maintained, especially since it is nearing three years since the last universal coverage distribution campaign. Either another campaign will be needed or efforts to strengthen delivery of nets to families through routine health services.

In addition prompt and appropriate treatment based on diagnostics can be strengthened. One would have expected more children with fever to have been tested for malaria that the DHS reports.

Internal and external support is needed. Rwanda has been on the verge of reaching malaria pre-elimination status several times in the past decade. Even though malaria is no longer the top cause of death, we should not reduce our efforts to create a malaria-free Rwanda.

Invest in Using Preventive Services: an Update from the 2014-15 Uganda Malaria Information Survey

MIS Uganda 2014-15The Demographic and Health Survey people have just released the preliminary MIS results for Uganda. From the viewpoint to the Millennium Development Goals (MDGs), there are cautiously positive signs.

Insecticide treated bednet ownership by households has reached 90%. Equity appears to have been achieved with the households in the lowest, second and third wealth quintiles registering 92%, 94% and 93% ownership. The highest and next highest quintiles had 85% and 88% ownership respectively. Those in the higher wealth quintiles often have better quality housing that of itself offers preventive benefits.

An interesting number is that over 86% of households obtained their nets through campaigns. It appears that the catch up phase of net distribution is repeating itself and the more sustainable keep up phase where nets are provided through routine services has not taken effect.

Household ownership of at least one net translates into use by only 69% of residents generally, and still only 74% in homes that actually own a net. Net use by ‘vulnerable groups’ was a bit better: 74% for children below five years of age and 75& for pregnant women. Thus we can see that household ownership does not guarantee that we meet the 2010 target of 80% coverage/use.

We have moved from recommending two doses of sulfadoxine-pyrimethamine as intermittent preventive treatment for malaria in pregnancy to three or more. The MIS does not report on increased doses but even for two contacts, only 25% of recently pregnant women in Uganda were covered.

The results show that malaria prevention is still an elusive goal. Thirty per cent of children given malaria rapid diagnostic tests during the survey had malaria parasite antigens. We must invest more in ensuring that preventive interventions are routinely available and are actually used before our attention is diverted from the MDGs to the SDGs.

RBM Consensus: Continuous Distribution of Long-Lasting Insecticidal Nets in Africa through Antenatal and Immunization Services

LLIN Statement HeadingThis statement is issued by the Roll Back Malaria (RBM) Partnership Working Groups on Malaria in Pregnancy and Vector Control, together with the Alliance for Malaria Prevention. Our aim is to appeal for more complete implementation of the WHO Recommendations for Achieving Universal Coverage With Long-Lasting Insecticidal Nets in Malaria Control (released September 2013, revised March 2014) [1]. In particular we wish to draw attention to this recommendation regarding long-lasting insecticidal nets (LLINs): “Continuous distribution channels should be functional before, during, and after the mass distribution campaigns to avoid any gaps in universal access to LLINs”.

Rationale

DSCN7129a pregnant women get ITNs when register for ANC RwandaIn most settings, pregnant women, infants and children under 5 years of age are at considerably higher risk of contracting malaria and developing severe disease than the general population. In sub- Saharan Africa, up to 90 percent of deaths due to malaria occur in infants and children under age 5. LLINs together with effective case management and intermittent preventive treatment in pregnancy (IPTp) are essential interventions for these vulnerable populations.

Antenatal care (ANC) and childhood vaccination clinics (i.e. those implementing the Expanded Program on Immunization, or EPI) offer effective channels for continuous distribution of LLINs since these provide a venue for structured visits targeting pregnant women, infants and young children. The use of ANC and EPI clinics for this purpose is further supported by the following considerations:

  • In most countries a large proportion of pregnant women attend ANC at least
  • EPI is one of the most equitable programs in child health, with high coverage globally.
  • Availability of LLINs in ANC and EPI sessions provides an incentive to attend and thus improves coverage of ANC and
  • Visits to ANC and immunization sessions are key opportunities for counseling pregnant women and mothers to promote the use of LLINs by pregnant women, infants and young

Other LLIN distribution channels may also offer good opportunities for achieving and maintaining universal coverage in addition to mass campaigns [1]. Each national malaria control program should develop its own LLIN distribution strategy that includes both mass distribution and continuous distribution channels, based on an analysis of the context of its local opportunities and constraints, and then document this in the national strategic plan. Program planning and implementation of continuous LLIN distribution should be conducted under the leadership of the national malaria control program, in conjunction with maternal health and EPI programs, as appropriate. Program implementers have an opportunity to reinforce counseling on the use of LLINs at ANC and immunization services.

Challenge

Some countries are faced with the challenge of insufficient LLIN stocks. Reports from several countries indicate that LLINs have been reallocated from ANC/EPI services to mass campaigns, as a means of compensating for shortfalls in stocks. However, we are concerned about this practice in the absence of an analysis of the impact on LLIN coverage of vulnerable groups. All possible efforts must be made to achieve or maintain universal coverage and, in the absence of sufficient LLINs, to avoid compromising coverage of vulnerable groups. Recognizing that intermittent mass campaigns are essential to maintaining high levels of coverage, and acknowledging that there may be disruption of routine systems during mass campaigns, every effort should be made to minimize these disruptions. The potential reallocation of LLINs from routine distribution channels to mass campaigns must be informed by local data indicating that this will not compromise protection of vulnerable groups such as pregnant women, infants and children under 5 years of age.

Action

The RBM Working Groups and the Alliance for Malaria Prevention therefore strongly urge national program managers responsible for malaria control, ANC and immunization services, and all health professionals concerned with these services, to heed and rapidly implement the WHO recommendations, which indicate that in addition to mass campaigns, a high priority should also be given to continuous distribution of LLINs during and after mass campaigns – such as through ANC, EPI services, and mother and child health weeks/months campaigns, as appropriate to the local context [1].

Monitoring Net Use: Ensuring a Major Investment Pays Off

wmd2015logoJohn Orok, the Director of Akwa Ibom State’s Malaria Control Program in Nigeria, and colleagues have shared with us the follow-up survey results following a mass LLIN distribution campaign in his state in late 2014. Unless we monitor our investments in nets, we will not “Defeat Malaria.”

While long lasting insecticide-treated nets (LLINs) have made a major dent in the incidence of malaria in Africa, LLINs need to be replaced at intervals. Akwa Ibom State Ministry of Health (SMOH) conducted a mass net distribution in 2010 during which 1.8 million LLINs were handed out in the 31 Beneficiary hang her Net 2015local government areas (LGAs/Districts). An estimated 2.7 million nets were acquired with Global Fund support for replacement distribution in November and December 2014. In an effort to learn about the outcome of the exercise, the SMOH organized a follow-up household survey in all LGAs in January 2015.

The state formed a technical working group which developed a checklist and interview guide for to gather follow-up information on the number of households that acquired nets, hung the nets, slept under the nets, their reasons for not using nets and sources of information about nets. Interviewers were recruited for each LGA and trained to use the checklist and recognize appropriate net hanging and use. Twelve interviewers were assigned to each Ward of each LGA.

Who Sleeps Under LLINs in Akwa Ibom StateA total of 2,696,476 net cards were issued to households based on approximately two nets per household, and 2,626,966 nets (97.4%) were redeemed. Retention rate in the sampled households was 97.1%, while hanging rate of those retained was 71.8%%. Overall 69.6% household members reported that they slept under a net the previous night. A greater proportion of pregnant women (92.1%) reported using nets compared to children below 5 years of age (82.3%) and other household members (63.3%). Main reasons for not using nets included feeling hot (44.5%), inability to hang the net (19.7%) and concern about the chemical used to treat the net (11.4%).

Akwa Ibom is located in Nigeria’s highest malaria transmission zone, and hence there is need to use LLINs throughout the year. The contrast with 2013 DHS, where only 14.1% of residents overall slept under an LLIN, results is stark and implies that net use may likely decline as nets age beyond an ideal replacement schedule of every 2-3 years. Even 1-2 months out from a campaign there are people who are not hanging and using nets. Continuous systems for community level education and reinforcement and health system-based routine distribution for periods between campaigns are needed to ensure this major investment in controlling malaria pays off..

Highlights from Malawi’s 2014 Malaria Information Survey

Two major forms of malaria data collection help inform national malaria control programs and their supporters about progress and help focus continued resources and interventions. Routine national health information tells us about program implementation on a regular basis. National surveys give us a point-in-time picture of coverage.  For the latter, Malawi has been fortunate in recent times to have conducted Malaria Information Surveys every two years.

Pf_mean_2010_MWIMalawi continues to have endemic malaria as documented by the MAP project in the attached graphic. While some of its neighbors in southern Africa are moving toward elimination, Malawi still experiences prevalence (as measured by rapid diagnostic test) in children below five years of age of 43%, 28% and 33% in 2010, 2012 and 2014 respectively.

In the chart below we can see that malaria preventive measures have varied in coverage over the three survey periods and may be said to be on a very slightly upward trend.  The Roll Back Malaria target of 80% coverage by 2010 and the US President’s Malaria Initiative target of 85% are still illusive.

In fact, simply having an ITN in the home is no guarantee that people will use it. Overall in 2014 72% of people living in a house with a net slept under one the night before the survey. The rate of use was better for children below five years of age (87%) and pregnant women (85%), but a gap remains.

Malawi MIS 2014 HighlightsOverall coverage for two doses of sulphadoxine-pyrimethamine (SP) for intermittent preventive treatment in pregnancy (IPTp) remains low. Now that WHO is recommending IPTp with SP during each antenatal care visit after 13 weeks, we are aiming for 3, 4 or more doses. In 2014 89% pregnant women in Malawi received one dose, 63% received two and 12% received three.

Malaria treatment for febrile children was the indicator with the best performance (not counting the fact that treatment was not always preceded by a diagnostic test).  Most (93%) of children took an artemisinin-based combination therapy (ACT) drug, and 74% took it within a day of fever onset.

The 2014 MIS provides more detailed breakdown by region and socio-economic group, which should be helpful for planning.  The major take home message though is that five years after the RBM target dates, many countries, Malawi included, have not been able to scale up and sustain the high intervention coverage needed to bring down mortality and guide us on the pathway to malaria elimination.

As the 2015 Millennium Development Goals are being replaced with a broader development agenda, we hope that malaria will not become a neglected tropical disease again. Actually using data from the MIS to take timely decisions by national programs and donors is essential to keep us on the path.

“Zero Malaria! Count Me In!”: Senegal’s national commitment to the Last Mile to Malaria Elimination

Yacine Djibo, Founder & President of Speak Up Africa is helping focus International Women’s Day (March 8th) on efforts to protect women from malaria in Senegal. She is highlighting the commitments of 8 strong and beautiful women, in Senegal, that are dedicated to eliminating malaria in their country. These commitments are part of an inclusive mass communication campaign that aims to launch a national movement in favor of malaria elimination in Senegal: the “Zero Malaria! Count Me In” campaign

ZeroPaluInternational Women’s Day, represents an opportunity to celebrate the achievements of women all around the world. This year’s theme is “Empowering Women – Empowering Humanity: Picture it” envisions a world where each woman and girl can exercise her choices, such as participating in politics, getting an education or fighting malaria. Below is the fifth feature on women fighting malaria.

Mrs. Oulèye Bèye, Head of the Prevention & Partnership Department at the National Malaria Control Program (NMCP), likes to remind us the national claim stating that “Technicians cure malaria but communities fight it”. It is a simple, yet powerful statement that summarizes the very purpose of all our endeavors. Efforts to reach remote populations and positively change communities’ behaviors are a constant battle for the NMCP.

Mrs. Oulèye Bèye, National Malaria Control Program, Senegal

The scale up of proven interventions recommended by the World Health Organization, have been essential in achieving this drastic decrease in malaria mortality rates over the years. These strategies include ensuring the availability of Artemisinin-based combination therapy (ACT) in health facilities, the mass distribution of free mosquito nets and the introduction of rapid diagnostic tests.

To be effective, all of them require significant and unconditional uptake by beneficiaries. Needless to say that the successes achieved through effective and safe malaria control campaigns, a strong national leadership and a dynamic set of partners are all at risk, if we fail to realize that populations must no longer be considered as plain beneficiaries but as stakeholders of utmost importance.

iwd_squareBy leading the effort around the “Zero Malaria! Count Me In” campaign at the national level, Ouleye strives to create a popular movement and actively engage each and every Senegalese citizen in the fight for a malaria-free Senegal. Sensitization and awareness raising must be the first step of any malaria elimination intervention if we want to achieve positive results in the long run.

Insecticide treated nets, a fishy subject

Not long ago I had written a blog posting suggesting that widespread misuse of ITNs/LLINs was probably not a major problem. To date the main official published information on the topic came from a community near Lake Victoria that had received an DSCN0189abundance of nets through uncoordinated donor activity and the excess was being used to dry fish on the shore.

True, newspaper articles over the years have featured Ministry of Health officials in numerous countries berating their citizens not to use nets for fishing, agriculture and other non-disease control needs, but evidence had not been forthcoming in the numerous national demographic, health and malaria surveys over the years. There is also the acknowledged possibility that old nets are being repurposed since there are inadequate disposal mechanisms available.

Such concerns are not idle. We also documented misuse of LLINs in Akwa Ibom State with photographs LLINs for goal post 3of nets used to make football goals, protect seedlings in a nursery, cover small kiosks selling food items and penning animals. This occurred in areas where there was inadequate partnership, planning and follow-up with the community by health officials.

Now the New York Times has stirred up the controversy again with strong visual evidence of a fishing communities in Zambia and Tanzania using ITNs for not only fishing, but also making chicken pens, ropes, footballs and football goals. People in that community explain their economic needs which are huge in this poor area of the world, and present the hard choice between augmenting their livelihoods and sleeping under an ITN. The environmental impact of the insecticides when nets are misused was also highlighted. The immediate thought is that malaria control efforts must be integrated into health and development efforts in a country.

The US President’s Malaria Initiative has issued a statement of concern. PMI recognizes that misuse of nets can depend on the particular environment (e.g. near water), but also recognizes the need, as mentioned above, of collaborating with the community to get things right in the first place. These problems will persist until national malaria control programs focus less on the total numbers of nets distributed and more on the actual factors that influence net use.

Is Mosquito Net Mis-Use Exaggerated

Health Officials commonly berate community members for misusing insecticide treated nets (ITNs) given out during malaria prevention campaigns and programs. Villagers are blamed for doing everything from using nets to catch or dry fish, protect crops or poultry, make football goals and cover their market goods.

For example, The Nairobi Star of 12 March 2012 reported that health officials in Nyanza, Kenya were disturbed that people were using their ITNs to protect their gardens from pests and their kitchens from rodents. The officials threatened to prosecute anyone misusing their nets.

LLINs for goal post 3Likewise the Lusaka Times published a story on 10 July 2011 that ITNs were being misused to made wedding dresses/veils and for fishing. “North-Western Province Minister Daniel Kalenga has directed District Commissioners in the province to report any misuse of Insecticide Treated mosquito Nets (ITNs) to the police as it is an offense under the public health Act.” A similar story appeared in April 2014.

There is some theoretical logic to net misuse. Keita Honjo and colleagues concluded from a modeling exercise that, “ITN use for malaria protection can be thwarted in settings of extreme poverty, where an increase in labour productivity by an alternative ITN use can offset the perceived benefits of avoiding malaria infection.”

One has often suspected these challenges to net use border on myth at times. Eisele and colleagues leveled the following critique against the media: “There are a number of potentially damaging misconceptions about insecticide-treated mosquito nets (ITNs) in Africa that have been propagated in media
reports, almost all of which are based on anecdotal accounts.”

Therefore, we were quite interested to learn of a newly published study that analyzed ITN use with “Data from 14 sub-national post-campaign surveys conducted in Ghana, Senegal, Nigeria (10 states), and Uganda between 2009 and 2012 (that) were pooled,” to find out what happens to “lost” nets.

Nets Lost to Household KoenkerWhile 16% of 25,447 nets were no longer serving their original purpose, only 6.2% of those were being used for another purpose. Importantly, over 3/4 of those had been damaged prior to re-purposing. The fact that the major reason why nets left the household was because they were given to other users (e.g. relatives) implied that better assessment of community need for nets was required.

In fact re-purposing of old nets may be a natural response to failure of health agencies to devise an environmentally safe way of disposing of ITNs that have passed their natural lifetimes. Therefore WHO recommends that National malaria control and elimination programs should work with national environment authorities work together to ensure proper removal of old nets no longer in use to prevent malaria.

This reassuring article certainly takes precedence over newspaper reports of misuse, but we should still be on the look out for net use problems. A classic example appeared in Malaria Journal in 2008 documenting with data and photos the use of ITNs to dry fish along the shores of Lake Victoria. In that case the root cause of the problem was lack of coordination among agencies such that the villages were supplied more nets than they needed. This appears to have been a one-of-a-kind study.

What is more likely to happen, it seems is that households acquire their nets but for various reasons do not always hang them, as was the case with nearly 30% of recipients in a small study in Rivers State, Nigeria. Malaria control programs need to pay more attention to helping people actually hang and use their nets correctly and regularly than simply being satisfied with reporting the numbers distributed.

Hearing, Seeing, Changing: Bednet Behavior

An important new article in Malaria Journal by colleagues at the Johns Hopkins University Center for Communications Programs gives confidence to health educators and behavior change practitioners that their interventions do make a difference. Using the 2010 Malaria Indicator Survey (MIS) from Zambia, they were able to comparing women’s reports of exposure to behavior change communication (BCC) messages and their use of insecticide treated nets (ITNs) the previous night.

CAM03755 smExposure to ITN messages was focused on women who “reported hearing or seeing any malaria messages in the past six months and also cited at least one specific channel: television or radio, in the newspaper, on posters or billboards, or from peer educators and drama groups.” Using two different analytic approaches, the authors found that exposure to messages was responsible for between 12-29% of net use. They concluded that the results “illustrate that BCC programmes can contribute to national programmes seeking to increase the use of ITNs inside the home.”

The recent MIS in a variety of endemic countries have taken up the task of measuring not just use of ITNs but also knowledge of the role of ITNs in preventing malaria and exposure to BCC messaging about ITNs.  Similar analysis should be performed on these data sets.

NetMark billboard aThe 2010 Nigeria MIS, for example, reported that 27.9% of women reported exposure to malaria messages in 4 weeks prior to the study. Likewise 57.9% of women had knowledge that Sleeping under mosquito net prevents malaria in pregnancy (MIP).  The 2012 MIS from Malawi reported that 25.3 women claimed exposure to malaria messages in past 4 weeks, and of those, 87.3% had knowledge that Sleeping under mosquito net prevents MIP.

A 2011 survey in Ghana found that 57.3% of women claimed exposure to malaria messages in past 4 weeks, and of those 83.7% had knowledge that Sleeping under and ITN prevents MIP. A question remains though, what was the actual nature of those media efforts to which women claim exposure?

The surveys do note the broad sources of information, e.g. radio, health workers/clinic, community activities. A review of overall national malaria strategies  and specific malaria BCC documents will certainly indicate that national programs and their partners intend to engage in a variety of BCC activities. The issue is whether, where and how those activities took place.

To give more validity to BCC outcomes, we must also encourage national malaria programs and their partners to document better their BCC activities so we can more easily attribute ITN behavior change itself to specific, funded interventions.
