PMI VectorLink Malaria Fighter: Duartina Francisco

Mozambique

Duartina Francisco serves as Country Operations Director and Gender Focal Person for the U.S. President’s Malaria Initiative (PMI) VectorLink (VL) Project in Mozambique. She began working in vector control with the PMI Africa Indoor Residual Spraying (IRS) Project in 2012. Duartina holds an MBA in Management of Integrated Systems, Quality Environment and Safety from Mozambique’s Higher Institute of Science and Technology and a Bachelor in Environment Management, Planning and Community Development. She’s a trained nurse in maternal and infant health and previously worked as a field officer and trainer on a project that focused on orphans and people living with HIV. Recently, Duartina took time out of her busy day to talk about her work.

What do you find most challenging about your job?

Convincing and mobilizing targeted populations to accept having their houses sprayed is the most challenging aspect (IRS involves spraying the inside walls and ceilings with an insecticide that kills the malaria parasite-carrying mosquitoes). There are lots of myths about IRS that make it challenging for people to accept IRS. The most recent widespread myth was that IRS spray operators were vampires and that mobilizers were marking houses to easily identify which households would have their blood sucked. This caused many households to remove all mobilization stickers and to wipe off any markings that mobilizers left on their houses as part of the house-to-house mobilization. IRS requires the entire community’s acceptance and efforts (The World Health Organization recommends higher than 85 percent coverage for IRS to be successful).

In Mozambique, community leaders are also political leaders and play a critical role in IRS. They are responsible for encouraging their community to stay at home and not to leave to farm on spray days so that they can have their houses sprayed. By involving local leaders before the IRS campaign began, we were able to dispel this myth.

Another challenge has been the impact of natural disasters, such as heavy rains and cyclones. While malaria incidence has decreased thanks to the project’s vector control interventions, the flooding and rains provide additional breeding grounds for mosquitoes, which results in higher abundance of mosquitoes and increased risk of malaria transmission.

What changes have you seen in IRS implementation since the PMI VectorLink Project began?

There has been an increase in the engagement of political leaders at all levels in malaria matters, especially for IRS. We have many political parties in country. In the past, it was difficult for a member of the opposition party to accept IRS because they saw it as political issue and not a health issue. This resulted in many refusals for spray in communities that were known to be affiliated with the opposition party. The project began having separate, focused meetings at both the provincial and local levels within the community structure to ensure that all political party leaders are involved in IRS. There used to be one central level meeting where leaders of the opposition political parties were not invited or represented. Once the meeting moved to different levels, it improved participation from all leaders.

How does the project reach the most vulnerable, particularly those not previously protected with vector control? Our target populations include those living in very remote places where it is difficult for them to reach basic health care services in time if they contract malaria and where there is little access to buy products to protect their houses against mosquitoes. We prioritize these areas for IRS first to ensure we reach them before it rains, when it becomes more difficult to travel. With the introduction of the IRS mobile soak pit, our work in remote areas is easier.

In IRS, spray operators rinse liquid waste from spray tanks and protective gear into soak pits that adsorb and safely degrade the traces of insecticide found in the wash-water. In most spray areas, soak pits are permanent installations in a central location that can be accessed at the end of the spray day. However, in some hard-to-reach areas, it is difficult and sometimes impossible for spray teams to return to a soak pit for clean-up purposes. The mobile soak pit, developed under the PMI Africa Indoor Residual Spraying Project, can be carried to a spray location, installed at a wash site in minutes, and used to catch and treat insecticide waste. When spray operations in the area are complete, the soak pit is dug-up and carried away for use at the next location, while the site is restored to its original condition.) We shared this innovation with other provinces, and they are using it, too, which helps us to ensure we don’t leave anyone behind.

Since the project began there has been a decrease in mortality from malaria. The reduction in malaria prevalence in Zambezia Province (where the project implements IRS) went from 68% to 44% between 2015 and 2018 in children under 5 years[1]. At the Zambezia’s 2021 malaria provincial evaluation meeting, the Provincial Health Directorate reported a 9.1% reduction in malaria-related deaths in its eight-month Zambezia malaria progress report in the districts that receive IRS and insecticide-treated nets. 

How does the project invest in local partners to lead malaria programs?

The project engages local partners to lead programs by sharing best practices in managing IRS activities. For instance, PMI VectorLink was the first project in the country to use checklists to supervise IRS activities. This best practice was adopted by the National Malaria Control Program (NMCP) and recommended to all partners to monitor IRS. The project also introduced the best practice of using the mobile soak pit in hard-to-reach areas, which is now being used by the government in three provinces.

Heads of health posts, malaria focal point persons, environmental health officers, among others from the Ministry of Health, have received training from the project. These staff have gone on to train government spray operators who are now capable of supervising spray campaigns. Our project checklists also have been adopted by the Ministry of Health and other partners to manage the entire malaria program, including monitoring malaria indicators at the country level. The VL environmental compliance checklist was adopted and used as foundation for the NMCP, not only for IRS but all malaria strategies implemented in the country. The government’s training of trainers’ curricula was also adjusted based on the project’s curricula. This impact has been very notable as the project is a model for IRS implementation in three regions of the country.

The project also provides entomology support to six provinces, including Zambezia where the project implements IRS. The reported entomological data helps the National Malaria Control Program to make informed vector control decisions for areas where the malaria incidence is increasing.

What progress have you seen in gender equity as Gender Focal Person?

In 2015, when the AIRS Project began to actively promote gender equity and female empowerment at all levels of IRS operations, it seemed like an impossible task to achieve. We started with 7% female participation in IRS. Now we are at 33%. Apart from numbers, I have seen many women apply for different positions (that have traditionally been held by men), such as drivers, spray technicians, site supervisors, and team leaders. At the beginning of the project, women were predominantly working as washers with some working as spray operators. So there has been very good progress, and I am very happy to be part of that.

Can you talk about how the project supports systems to be resilient against the COVID-19 pandemic and other shocks?

Running the vector control activities during the ongoing COVID-19 pandemic has been a challenge. The PMI VectorLink Project works across 26 countries to protect people from malaria. With such a big project, there is diversity of ideas, contexts, and challenges. We learned lessons from other countries that sprayed under the pandemic before Mozambique. As a result, we adjusted our operating procedures, and with Mozambique’s Ministry of Health (MOH) guidance, we developed an action plan to ensure to minimize the spread of COVID-19 among the team. Continuous sharing of information and experiences will contribute to the project being resilient against pandemics and other shocks in the future.

Do you think Mozambique will ever be malaria-free?

Yes, by continuing to implement integrated vector control and management strategies, it can be. There are many interventions taking place at the national level, such as housing improvement, environment sanitization, and massive distribution of bed nets. The integrated vector control management model has shown progress towards elimination in the southern part of the country, which was declared to be in the malaria elimination phase by Southern Africa Development Community in 2020. My hope is that the NMCP continues making efforts in the adaptation/adoption of the tools and best practices used under VL to fight malaria and to expand IRS to other provinces, since the whole country is endemic for malaria.

ITN Champions Aim to Increase Use of Nets

Ghana

Insecticide-treated nets (ITNs) are a proven vector control intervention for reducing malaria illness and death. The PMI VectorLink Project supports National Malaria Control Programs (NMCPs) and stakeholders to implement mass ITN distribution campaigns. In Ghana, the NMCP and partners have distributed ITNs through mass campaigns and routine channels to ensure high ownership. Since 2010, the country carried out four national mass campaigns, and implemented routine distribution of ITNs through health facilities (antenatal and child welfare clinics) and primary schools.  

However, analysis of the 2016 Malaria Indicator Survey (MIS) showed that 24 percent of people who have ITNs don’t use them and Ghana has a use: access ratio (an estimate of the proportion of the population using nets, among those that have access to one within their household) of 63 percent. This prompted research to understand the motivators and barriers of ITN use. A 2018 qualitative study[1] identified ITNs as a key method to protecting people from malaria, but heat, discomfort, and reaction to insecticides were identified as main barriers to use.

Using the findings of the 2018 study and analysis of the 2019 MIS data, which also showed 24% of people with ITNs do not use them, the PMI VectorLink Project, NMCP and the Central Regional Health organized a workshop to design behavior change interventions that could increase ITN use in households and communities in December 2019. The project, working with the local nonprofit Total Family Health Organization (TFHO), trained 175 midwives and community health nurses from 114 health facilities in five districts as ITN use and care champions in the Central Region. The aim was to promote positive ITN use and care behaviors among pregnant women, caregivers of children under five, and the entire community. The champions pledged to promote consistent use of ITNs and were provided with a badge and pledge form to display. Additionally, they were equipped with a radio to play recorded messages and other job aids to educate the targeted beneficiaries on ITN use and care. Key messages discuss the benefit of ITNs, their cost effectiveness compared to other tools favored by the population like mosquito coils, proper use of ITNs, and misuse of ITNs.

Edith Asare, a midwife with more than 30 years of experience and a trained ITN champion through PMI VectorLink Ghana, now plays the messages during antenatal care or child welfare sessions, where women have access to ITNs as part of routine channels, to stimulate lively discussions among pregnant women. The pregnant women often leave the antenatal clinic at the Swedru Hospital in the Central region of Ghana with a pledge to sleep under an ITN every night and to become an ITN use and care champion in their communities.

“This intervention is a very positive one. I don’t see this as a [short-term] project but should be part of our approach to continuously educate pregnant women to use ITNs to protect themselves and their unborn baby. This is important as we give out ITNs as part of our routine care to registrants. It should form part of what we do daily. I’ll always promote ITN use,” said Edith.                                                                                

PMI VectorLink Ghana is working with TFHO and the Eastern and Central region health directorates to scale up implementation to additional 40 districts. They aim to train 2,713 midwives and community health nurses and 4,976 community health management teams (CHMTs)/opinion leaders as ITN champions.The addition of CHMTs is to ensure the community members are involved in planning and implementation of interventions that will promote ITN use and care and to ensure ownership.

PMI VectorLink Mali’s Collaboration with Local Leaders in IRS Ensures Communities in Bandiagara, Djenne and Mopti Districts are Protected from Malaria

2021 IRS Campaign Launch, with Mr Moussa Kamian, Village Chief of Soufouroulaye, June 7, 2021 (Mopti District)

The COVID-19 pandemic continues to challenge public health workers implementing malaria interventions across the globe. In Mali, ongoing civil unrest added to those challenges, putting critical vector control services at risk. The U.S. President’s Malaria Initiative (PMI) VectorLink Project supports countries to conduct indoor residual spraying (IRS) to kill and repel the mosquitoes that carry the malaria parasite, which can infect people and cause serious illness and death. PMI VectorLink Mali collaborated closely with communities to ensure people were protected from the deadly disease of malaria despite these challenges.

PMI VectorLink Mali communicated regularly by phone with local administrative authorities and community leaders to effectively monitor the security situation in the areas it sprays. When security issues prevented spray teams from adhering to the planned spray operations, the village chiefs were contacted by the spray team to reschedule the spray date, and the project closely tracked the  ongoing security situation.

The local administrative authorities also played an important role in increasing community awareness and acceptance of IRS. For example, PMI VectorLink Mali engaged village chiefs and their deputies to ensure homeowners were prepared to accept IRS. One day before the arrival of the spray team, under the authority and direction of the village chief, the Information, Education and Communication (IEC) mobilizer went door to door providing important information to the community about IRS and reminded homeowners how to prepare their houses for spraying.

In previous years, PMI VectorLink Mali came across homes in rural areas that were locked due to people working in agricultural fields when the spray teams arrived. However, this year, thanks to community collaboration, homeowners were well prepared, and PMI VectorLink Mali was able to safely conduct the spray campaign. As a result, PMI VectorLink Mali successfully completed the 2021 IRS campaign, protecting approximately 233,663 people, including 45,249 children under five years old, and 17,768 pregnant women. The team exceeded its target spray coverage of 85% to reach 96.7% spray coverage during the campaign as a result of the strong relationship and trust the project has built with local partners and beneficiaries.

“We trust that once again this year, thanks to IRS, there will be fewer and fewer cases of malaria in our community,” said Sogoba Dembele, President of the Women’s Association in Bounguel, Djenne District. “As mothers, we are very pleased for that because it will prevent us from spending our time in hospitals, which gives us time for taking care of our daily business for the well-being of the whole family.”

PMI VectorLink Published Paper Explores New Ways to Reduce Burgeoning Costs of Vector Control to Fight Malaria

New findings from the U.S. President’s Malaria Initiative (PMI) VectorLink Project published in Scientific Reports today show the potential for reducing costs of indoor residual spraying while retaining efficacy in killing the mosquito species known to spread malaria. Over the past two decades, massive reductions in deaths and illnesses from malaria have come from IRS, which uses insecticides to kill the mosquitoes that carry the malaria parasite. Increasingly, those gains are threatened as widespread resistance to commonly used pyrethroid insecticides calls for the use of new and costly insecticides for IRS. Faced with increasing operational costs, the PMI VectorLink Project led a study in Ghana in collaboration with Noguchi Memorial Institute for Medical Research and Imperial College London to find innovative ways to effectively combat malaria with the reduced use of insecticide. In a village-wide trial in northern Ghana using experimental huts and houses, the team evaluated the efficacy of reducing the area of wall sprayed with the insecticide pirimiphos-methyl against Anopheles gambiae s.l., the primary vector that spreads the disease. 

Experimental huts and houses in northern Ghana used to study the efficacy of partially-sprayed walls in IRS.

The transmission model “predicts that the efficacy of partial IRS against all-age prevalence of malaria after six months would be broadly equivalent to a full IRS campaign in which 40% reduction is expected relative to no spray campaign. At scale, partial IRS in northern Ghana would have resulted in a 33% cost savings ($496,426) that would enable spraying of 36,000 additional rooms. These findings suggest that partial IRS is an effective, feasible, and cost saving approach to IRS that could be adopted to sustain and expand implementation of this key malaria control intervention.”

PMI VectorLink Senior Technical Advisor Aklilu Seyoum said, “This very important study strongly indicated that partial IRS could be a good alternative to the current practice of full IRS. This has the potential to increase the population protected by IRS and save more lives in malaria-endemic countries. A more rigorous randomized control trial is now being planned by the PMI VectorLink Project before large-scale application of this important approach can be used in the control programs.”

PMI Collaborates with Communities to Beat Malaria

The U.S. President’s Malaria Initiative (PMI) VectorLink Project collaborates with national and local governments to identify, study, and record where malaria-transmitting mosquitoes live, how they feed, when they rest, and the density of their population. In Kenya, PMI trained community health volunteers on how to catch and monitor mosquitoes, expanding the national government’s geographical reach to collect critical data on mosquitoes from two counties. This data will help to inform vector control decision making in the fight against malaria. 

Women in Entomology

From the Field to the Lab, Women Fight to End Malaria

Gains in reducing morbidity and mortality from malaria depend on the use of effective insecticides in vector control measures, such as IRS and ITNs. With more people qualified to carry out entomological monitoring, PMI is equipping country partners with the tools and knowledge needed to fight this deadly disease. This World Mosquito Day, PMI VectorLink celebrates the women in science who find, share, and use entomological evidence to fight malaria in their own countries. Read about them here.

Community Leaders Help to End Malaria

In Tatale-Sanguli District (TSD) of Northern Ghana malaria mortality dropped by 80 percent from 2018 to 2020, according to reports from the regional health directorate. This decrease corresponds to the support the district started receiving from the U.S. President’s Malaria Initiative (PMI) VectorLink Project, which conducts indoor residual spraying (IRS) to kill the mosquitoes that carry the malaria parasite. By 2021, with the help of the project, the leaders of the district’s Tangbabong community knew that fighting this deadly disease required commitment. For IRS to be successful, 85 percent of the homes in the targeted area must be sprayed to achieve community protection. In Tangbabong, these community leaders see IRS as a top priority in their efforts to end malaria.

When the chief and elders are informed about the spraying date, they prepare the community. A gongong (a local drum at the chief palace used to make important announcements) is beaten to inform community members about the benefits of the spraying and the date it will occur. Community leaders mobilize households and support community health volunteers to remind homeowners to prepare for spraying and to comply with health and safety guidelines.

On the day of spraying, every household removes their belongings from their homes and dedicates the day to spraying-related activities, including providing water for mixing insecticide. In some instances, a community health volunteer together with community members prepare the homes of neighbors who have traveled to ensure that no one is missed in benefiting from IRS. This support is also extended to neighbors who are unable to remove their belongings themselves. Upon the arrival of the spray team, homeowners are so eager to have their homes sprayed early that they will urge spray operators to come to their homes first.

While the spray team is in the community, the chief and elders meet with the project team to express their appreciation and hope that together malaria can be eliminated just as guinea worm was in the Northern Region in 2010. If a home is not sprayed during the first IRS visit, community elders follow up with a community health volunteer or community health nurse, and in some instances, through a recruited project staff living in the community, to request the spray team to revisit the community.

The success of IRS in Tangbabong (98.8% spray coverage) in 2021 is largely due to community leaders taking the steps needed to ensure that the community is protected from the disease and because community members recognize that vector control is a part of their communal responsibility.  It was after the 2020 spray campaign when spray coverage reached 92.9% that the chiefs and elders of Tangbabong decided to increase coverage in subsequent campaigns. Engaging the community in the 2021 IRS campaign resulted in the improved coverage of 98.8%, protecting 410 community members. Today, community leadership is happy to have one of the best spray coverages comparable to their 10 neighboring villages where the average coverage is 94%.

Chief Bechanignan said, “I previously could not enjoy the evening breeze in my home because of mosquitoes, but now I am able to do so for a long while before going to bed.”  He expressed his gratitude and pledged to “always ensure that his community participates in IRS.”

 

PMI VectorLink Extended to further Its Work in Ending Malaria

The U.S. President’s Malaria Initiative (PMI) recently extended the PMI VectorLink Project another 12 months, continuing its work to September 2023. Led by Abt Associates in partnership with Population Services International and PATH along with the support of Liverpool School of Tropical MedicineMalaria ConsortiumInnovative Vector Control ConsortiumMcKinsey & Company, Inc., EnCompass LLCBAO Systems LLCDigital Globe, and Dimagi, Inc., the PMI VectorLink Project initially began in September 2017 as a five-year project to reduce the burden of malaria.

The one-year extension reflects the project’s success in planning, implementing, and monitoring life-saving vector control programs for indoor residual spraying (IRS) of insecticides and distribution of insecticide-treated bed nets (ITNs) across 24 countries in sub-Saharan Africa as well as in Cambodia and Columbia.

PMI VectorLink successfully navigated the challenges presented by COVID-19, including border closures, national lockdowns, and serious delays and drastic cost increases in the production, supply, and delivery of malaria commodities. Some of the highlights from 2020 include:

  • 21.3 million people protected from malaria through 16 timely, high-quality IRS campaigns

  • 3.49 million children and 636,527 pregnant women protected

  • >58,000 seasonal workers hired to support IRS (33% female)

  • >5.8 million insecticide treated nets (ITNs) distributed

  • 5 peer-reviewed journal articles published on studies that assessed malaria risks and increased trust in new vector control approaches

PMI VectorLink is excited to continue its fight to end malaria! Keep following us on our journey.
