Emerging viruses in older population Chikungunya, West Nile fever and Dengue
There is a worldwide spread of vector-borne diseases due to several factors: it is easy for humans or vectors to travel by plane or boat from a continent to another one, climate changes allow mosquitoes to increase their abundance and geographical distribution worldwide, and urbanization and high population density favor inter-humans disease transmission. An outbreak of arboviral disease may occur when these three following conditions are met: the presence of a competent vector in an area with an infection-naïve population and viraemic travelers . In Europe, competent vectors are present like Aedes albopictus, A. aegypti or Culex pipiens, European population is in majority, naïve for West Nile virus (WNV) infection, Chikungunya or dengue and finally travelers from endemic area are potentially infected when they come back to Europe. These emerging diseases do not spare older population. They use to travel in endemic area and for those who do not travel, naïve older population in...
