Figure 6. Risk of ‘silent’ Zika virus spread from the outbreak in Cuba during 2017.
Travel volumes from Cuba and Ae. aegypti suitability were used to address the potential spread of Zika virus from Cuba during the outbreak in 2017. (A) Monthly Zika cases associated with international travel reported by the FL-DOH and the ECDC, sorted by travel origins in Cuba or all other countries/territories in the Americas, were used to demonstrate that >98% of all travel-associated Zika cases during June-December of 2017 came from Cuba. (B) During June-December, 2017, all countries and U.S. states that received > 20,000 airline passengers from Cuba are shown, along with the relative Ae. aegypti suitability, to represent possible destinations for Zika virus spread from Cuba. The data used for this figure can be found in Supplemental File 1.
