According to Costa Rican health authorities, although there is no case in Costa Rica, the Pan American Health Organization (PAHO) has issued an alert for the region to prepare against the threat of a virus called Chikungunya.

The pain associated with CHIKV infection of the joints persists for weeks or months, or in some cases years.

Costa Rica’s Ministerio de Salud (Ministry of Health) said they will keep fighting the mosquito Aedes aegypti , which was launched due to the dengue epidemic, since vector control is the only way to prevent this type disease

Chikungunya virus is indigenous to tropical Africa and Asia, where it is transmitted to humans by the bite of infected mosquitoes. Chikungunya virus belongs to alphavirus genus of the Togaviridae family. It is an “Arbovirus” (Ar-arthropod, bo-borne).

CHIK fever epidemics are sustained by human-mosquito-human transmission and there are no specific treatments, and no vaccine is currently available.

Prevention. The most effective means of prevention are protection against contact with the disease-carrying mosquitoes and mosquito control. These include using insect repellents.

Last week the World Health Organization (WHO) reported two cases of Chikungunya, Now the outbreak has grown to 10 cases, the Centers for Disease Control and Prevention said Wednesday. And the outbreak is likely to get even bigger or spread to other Caribbean islands.
