Data from nine cities in Mexico confirms that identifying dengue fever “hot spots” can provide a predictive map for future outbreaks of Zika and chikungunya. All three of these viral diseases are spread by the Aedes aegypti mosquito.

This study's results found a 62% overlap of hot spots for dengue and Zika and a 53% overlap for cases of dengue and chikungunya.

The journal Lancet Planetary Health published the research on July 7, 2021. This study provides a risk-stratification method to more effectively guide the control of diseases spread by Aedes aegypti.

The work was funded by USAID, the U.S. CDC, the Canadian Institute of Public Health, the state of Yucatan, the National Institutes of Health, and Emory University.
