PMI VectorLink Niger

Objectives

The project’s key objectives for each component are as follows:

Entomological monitoring:

  • Determine the susceptibility of the primary malaria vector, gambiae s.l., to insecticides in 15 sentinel sites selected by the NMCP, which are spread across the four transmission zones;
  • Measure the intensity of resistance to insecticides and determine the mechanism of resistance in the sites where resistance is detected;
  • Monitor the density, species composition, behavior, and infectivity of malaria vectors in the six sentinel sites;
  • Ensure the use of the District Health Information System 2 (DHIS2)-based VectorLink Collect database for improved entomological data monitoring, reporting, and decision making by relevant stakeholders; and
  • Conduct ITN cone bioassays in accordance with WHO recommendations using wild collected gambiae s.l. from two localities selected by the NMCP, with ITNs procured by PMI for routine distribution.

National entomological monitoring capacity-strengthening activities:

  • Conduct monthly meetings with CERMES staff and technicians and the NMCP Entomology Unit technicians to monitor progress toward objectives, follow up on activities, and identify/resolve challenges;
  • Provide technical support to the CERMES in insectary management and report-writing with NMCP supervision;
  • Conduct a refresher training in entomological collection methods;
  • Support an advanced laboratory training for experienced entomologists at CERMES provided by the University of Notre Dame to ensure total capacity building on all PCR and ELISA techniques as well as the interpretation of PCR results as requested by CERMES;
  • Support successful access and use of the DHIS2-based VectorLink Collect database by relevant users including CERMES, and the NMCP;
  • Continue to offer data quality control and data interpretation support to build NCMP capacity to make evidence-based vector control decisions;
  • Train two field technicians from the Districts of Keita and Balleyara on basic entomological techniques (building district level capacity in addition to the two agents trained in Gaya and Agadez in 2021); and
  • Support the organization of two meetings of the vector control working group, to review country national data for decision making.

National capacity building for ITN distribution:

  • Coordinate with the NMCP and PMI Impact Malaria project to organize and carry out an integrated bi-annual supportive supervision including ITN Continuous Distribution follow-up in the two PMI focus regions (Dosso and Tahoua);
  • Support the presentation of results from ITN durability monitoring activities held over the three years following the 2018 mass campaign, with the final product being a peer-reviewed publication;
  • Support radio dissemination of key messages in local languages about prenatal care and child health services in the two targeted regions;
  • Provide financial support for a 3-day information visit by high level MOH persons (members of the organizing committee of the 2022 ITN mass distribution campaign) to inform the local authorities on the organization of the campaign (in a context of insecurity). The visit will be conducted  in the form of a workshop in Dosso and Tahoua bringing together all the 13 prefects of the districts concerned by the 2022 campaign; and
  • Provide technical assistance during the ITN 2022 mass distribution campaign if requested by NMCP and CRS.

Rationale and Abstract

Malaria is endemic in Niger and is the leading cause of death and morbidity combined, disproportionately affecting children under 5 years of age. According to the Annual Health Statistics Report (2020), there were more than 4,332,909 malaria cases and 6,098 malaria deaths in Niger in 2020, compared to 3,621,972 malaria cases and 3,761 malaria deaths in 2019 (according to the Annual Health Statistics Report 2019), representing an increase in cases of 20% over the previous year and an increase in deaths of 62% over the previous year, putting it among the countries with the highest per capita rate of malaria fatalities globally.

According to the Niger 2017-2023 National Strategic Plan, the vast majority of Niger’s population (94%) resides in the two southernmost (moderate and high transmission) zones, where malaria is most prevalent. The rainy season in Niger lasts three to four months, from June to September, with peak malaria transmission during the second half (August and September) of this period. With the new malaria epidemiological stratification, there are four endemicity strata in Niger (very low transmission, low transmission, moderate transmission, and very high transmission).

Despite the enormous progress Niger has made in recent years in the fight against malaria, the disease remains a real public health problem in the country. The situation is worrying – the 2021 world malaria report of the World Health Organization (WHO) ranks Niger among the eight African countries which together account for about 60% of cases and deaths due to malaria. The WHO recommends universal population coverage with ITNs as a prevention strategy in malaria control programs. Since 2009, with the support of partners, Niger has been carrying out ITN mass distribution campaigns in addition to delivering ITNs through the continuous distribution (CD) channels of routine antenatal care for pregnant women and the Expanded Program on Immunization for children under 1 year of age. Nevertheless, according to the 2019 world malaria report, the ITN coverage rate has increased very little since 2015, which leaves the country far from its universal coverage goal.

Activities and accomplishments:

  • Trained 20 technicians to do field entomological monitoring using all collection methods both for the vectors bionomics and to determine the status of vector susceptibility to insecticides.
  • Strengthened the laboratory capacity of the Centre de Recherches Médicale et Sanitaire (CERMES) to perform molecular analyses (PCR and ELISA) of mosquito samples collected in sentinel sites.
  • Enabled the country to conduct—for the first time—bio-efficacy tests (in WHO cone and tunnel) for the ITN durability study in 2022, which had previously been done for two years in an external laboratory.
