More than 25 million people are at risk of dengue, which is more than half of Colombia’s population. A number of large-scale outbreaks have occurred in recent years. The number of Zika cases also increased rapidly following a global outbreak of the mosquito-borne disease in 2015.
(Data updated December 2021)
A large-scale research trial is now underway in Bello and Medellín. Recently, three new cities have joined this initiative: Cali in the Cauca Valley, and Itagüí and Sabaneta in the Aburrá Valley.
As well as measuring the impact of Wolbachia on the transmission of mosquito-borne diseases, our research in Colombia is expected to demonstrate a significant reduction in the number of new cases of dengue, Zika and chikungunya.
Following many years of laboratory research and field trials with promising results, we have received widespread support from communities, governments and regulators around the world.
The World Mosquito Program’s work in Colombia is generously supported by the US Agency for International Development (USAID) through the Combating Zika and Future Threats Grand Challenge.
