For the first time, the Republic of the Marshall Islands is reporting an outbreak of dengue fever. The cases have been seen almost exclusively in the capital, Majuro. The Ministry of Health is advising all residents of the Marshall Islands on mosquito avoidance measures.
Dengue fever is the most common cause of fever in travelers returning from the Caribbean, Central America, and South Central Asia. Dengue is reported commonly from most tropical and subtropical countries of Oceania, Asia, the Caribbean, the Americas, and occasionally Africa. This disease is caused by four similar viruses (DENV-1, -2, -3, and -4) and is spread through the bites of infected mosquitoes.
Dengue virus transmission occurs in both rural and urban areas; however, dengue is most often reported from urban settings.
