Surveillance identifies gaps in malaria control efforts 0

[KAMPALA] Although malaria burden is gradually falling globally, it remains high and continues to rise in high-transmission areas, especially in rural Africa, a two-year surveillance in Uganda has shown. According to the researchers who undertook the study, successes recorded for malaria control in Sub-Saharan Africa are mostly limited to low-transmission areas, noting that research in high-transmission regions are needed.

Therefore,the researchers based in Uganda, United Kingdom and the United States conducted surveillance studies from August 2011 to September 2013 in three sub-counties of Uganda, representing a low-transmission, peri-urban area and two rural areas with moderate- and high-transmission intensities.

In the study, which was published in the American Journal of Tropical Medicine & Hygiene last month (16 March), researchers enrolled 755 children aged 6 months to 10 years from 300 households, randomly selected from the three sites. Families were provided with insecticide-treated bednets and had access to 24-hour free medical care at designated study clinics for episodes of fever.

Children were also routinely tested for malaria even without symptoms, and mosquito specimens were collected monthly from light traps to estimate the percentages of mosquitoes in the study areas that were carriers of malaria.

“We found that the incidence of malaria decreased in the peri-urban site, but actually increased in the two rural sites over the course of our study,” says Philip Rosenthal, a co-author of the study and a professor of medicine at the US-based University of California, San Francisco.
