Abstract

Background:

Mosquito-borne diseases remain a major health concern threatening more than 40% of people worldwide. The presence of the pathogens and their vectors in the same area constitute key factors for the maintenance of vector-borne diseases. Seeing this, hospitals appear to be an area having high risk of mosquito-borne diseases transmission. This study aimed to evaluate the risk of chikungunya, dengue fever and malaria transmission in the CHUSS.

 

Method: We collected mosquitoes outside the hospital buildings using the Human Landing Catch technique and BG traps during 4 consecutive days. Specimens belonging to the Anopheles gambiae complex were identified using molecular techniques as well as detection of Plasmodium falciparum infection and blood meal source.

Results: Overall Culex quinquefasciatus, Anopheles gambiae s.l. and Aedes aegypti were the most abundant mosquito found in the study area. Anopheles arabiensis was the most abundant malaria vector (70.16%, n = 207), while Aedes aegypti was the main arbovirus vector, with a positivity index of 1. Further, PCR-based blood meal identification showed that the majority of blood meals from Anopheles gambiae s.l. were from human and goat hosts (42.11%, n=16). Of 282 Anopheles gambiae s.l. tested, (21.98%) were found carrying Plasmodium sporozoites. Anopheles arabiensis played a major contribution in malaria transmission in CHUSS, being responsible of 17.02% infection rate.

 

Conclusion: In our study, we observed a high density of mosquitoes associated with a risk of disease transmission. The Plasmodium falciparum infection rate was very high. This study should alert decision-makers about the risk of mosquito-borne disease transmission in hospitals.
