An endemic virus from Africa and Asia, the chikungunya, against which there is currently no vaccine or specific treatment, could be extended to other areas of the planet, especially the United States and Latin America, after the cases of people who have been infected after returning from a trip have significantly increased. The United States, which has gone from only three cases detected between 1995 and 2005, to 106 between 2006 and 2010.

The virus causes a disease that is not usually fatal but causes the affected fever, and a pain in the joints that can last for years

This virus, which transmit mosquitoes like Aedes aegypti -Responsible also for the transmission of yellow fever and the dengue- and Aedes albopictus (tiger mosquito) through the bite, the virus causes a disease that is not usually fatal but causes the affected fever, and a pain in the joints that can last for years. The mosquitoes that act as vectors of the infection can be found in various regions of America and throughout the Southeast and the West Coast of the United States, so in case these populations of mosquitoes were infected with the virus, they could transmit it. easily to local residents.

To try to stop the possible spread of the virus at local level - a risk associated with infected travelers returning to their places of residence - the Pan American Health Organization (PAHO) has prepared an informative guide, with the participation of the Centers for Control and the Prevention of Diseases of the United States (CDC), with the aim of improving the protocols of prevention, early detection and control of the infection by chikungunya in case it is necessary.

In Asia and Africa there are more than two million people infected with the chikungunya virus, which in some areas affects up to 68 percent of the population. The infection has also reached Europe, where cases have been documented in France and Italy. Surveillance and control of vectors are the only available resources to avoid as far as possible the settlement of the virus outside their areas of origin, since for example in Spain and southern France there are adequate conditions - which include the presence of mosquitoes tiger-, so that the virus establishes itself.
