Dengue and Coronavirus disease (COVID-19) syndemic: Double threat to an overburdened healthcare system in Africa.

ABSTRACT

Dengue fever (DF) is a significant public health problem in the African continent. The primary prevention strategy against the disease is vaccination and entomological control of vectors; however, implementing such a strategy in several countries in the continent is far below what is necessary to control the disease. The Coronavirus disease (COVID-19) pandemic further aggravated this situation and negatively impacted these measures, mainly the coverage of vaccination campaigns, due to restrictive measures to control the disease. Therefore, the most significant risk is that the incidence of DF in the continent will increase even more in the coming years, as a reflection of the negative impact of the pandemic on the control of the disease. To prevent another public health crisis, immediate and multidisciplinary approaches are required to address the epidemiological control of DF in African countries.
