1.3 billion people estimated to be living in areas at-risk of CHIKV transmission
Nsoesie and Kraemer et al have published research article, 'Global distribution and environmental suitability for Chikungunya virus, 1952 to 2015' in Eurosurveillance, and using an established modelling framework that combines a comprehensive occurrence database with bespoke environmental correlates, including up-to-date Aedes distribution maps, have comprehensively assessed the global distribution of chikungunya and produced high-resolution maps.
Chikungunya fever is an acute febrile illness caused by the chikungunya virus (CHIKV), which is transmitted to humans by Aedes mosquitoes. Although chikungunya fever is rarely fatal, patients can experience debilitating symptoms that last from months to years.
The authors identified 94 countries with good evidence for current CHIKV presence and a set of countries in the New and Old World with potential for future CHIKV establishment. 1.3 billion people were estimated to be living in areas at-risk of CHIKV transmission.
