Key Points
Malaria
- The number of malaria cases recorded in the country remained low and stable over the past two weeks, with 6 cases reported (2 in Week 29 and 4 in Week 30, provisional data) compared to a total of 3 in Weeks 27 and 28. Among these 6 cases—all caused by P. vivax—there was one relapse. Since the beginning of the year, 138 cases of malaria have been recorded, including 20 in May, 9 in June, and 10 in July. Over the past three months, most infections have occurred in gold-mining areas in the Savanes sector.
Bronchiolitis

If this downward trend is confirmed, the end of the epidemic could be declared shortly. For now, the outbreak continues across the region.
