De chikungunya-epidemie in de Cariben

• In 2013, the first autochthonous cases of the chikungunya virus (CHIKV) were reported on the Caribbean island of Saint Martin. The chikungunya virus has since become endemic in the Caribbean due to autochthonous transmission.
• In the presence of fever and joint symptoms in any traveller returning from the Caribbean, CHIKV should be considered.
• Although symptoms resemble those of dengue fever, the course of chikungunya is milder. Chikungunya much more commonly causes chronic joint pain.
• Laboratory tests for the chikungunya virus may give false positive results due to cross reactions with closely related viruses, so taking a full disease and travel history from the patient is necessary in order to interpret these test results correctly.
• There is no specific treatment for the chikungunya virus. A correct diagnosis can prevent unnecessary additional tests and unjustified treatment.
• The chikungunya virus can be prevented by the use of insect-repelling substances, nets and air-conditioning.
