Fig 2. Percentage of houses infested with female Ae. aegypti positive for any of the three targeted viruses in low-density (<10 total mosquitos per house, n = 98) and high-density (> 10 total mosquitoes per house, n = 70) premises, estimated from Ae. aegypti collected indoors during the ABV transmission seasons of 2016 and 207 in Yucatán, Mexico.

Panel A shows houses with positive bodies and heads and panel B shows the percentage of houses where only heads were positive. The variable co-occurrence contains percentages of houses where mosquitoes where positive for either virus within the same house, including three positive mosquitoes with coinfection between CHIKV and ZIKV.
