“ASo far the results are promising, they are positive, due to the results achieved. There was a reduction in the mosquito population in those homes that were sprayed with the repellent, compared to those that did not benefit”, Joaquim Domingos Lequechane, main researcher at CIOB, from the Mozambican National Institute of Health, explained to Lusa today.
The study, which also involves the Institute of Hygiene and Tropical Medicine, in Lisbon, and the Gorongosa National Park, included a sample of 1,410 people, corresponding to 302 households in the community of Tambara, in Nhamatanda, and this repellent was used of Portuguese manufacture to spray the walls of houses, measuring its level of effectiveness, namely as an “innovative alternative to insecticides”, to which mosquitoes show resistance.
During the process, interior and exterior walls were sprayed with the repellent, to “drive away” the mosquito that transmits malaria and reduce its population.
The provinces of Sofala and Tete are those with the highest rates of malaria patients in Mozambique.
World Malaria Day is celebrated annually on April 25th.
Financed over two years with 382 thousand euros by the Belmiro de Azevedo Foundation, from Portugal, and implemented by the CIOB, this project is carrying out research in the province of Sofala, mainly in Tambara, to evaluate the protection provided by the use of that repellent against malaria .
It is a repellent used for over 30 years and one of the most common among those applied to the body, being less toxic, but it is being tested as an environmental repellent, in homes and places with large concentrations of people.
“It is one of the most effective there is and so far we have no restrictions on its use, even on people with health problems or those allergic to insecticides, pregnant women, children, among others. This repellent works efficiently”, stated the researcher, with based on preliminary data from the study.
According to the director of the National Malaria Control Program, Baltazar Candrinho, the number of cases of the disease increased, with 13 million cases recorded in 2023, against 12.4 million in 2022, an increase of 17%, but the number of deaths due to malaria tends to reduce, with 357 deaths recorded in 2023, compared to 423 in 2022.
