The Centers for Disease Control and Prevention (CDC) are reporting the first domestically acquired cases of the mosquito-borne chikungunya virus.

Two infected individuals have been identified in Florida; neither had left the country recently enough to have contracted the virus elsewhere.

Chikungunya is not new to the United States; according to the CDC, the US sees an average of 28 cases per year. Until this point, however, these incidents have occurred exclusively in travelers returning from countries where the virus is common.

Symptoms of the Chikungunya virus include fevers and joint pain that usually cease within a week, although the latter can become chronic. Although no vaccine is available, the virus is very rarely fatal, and both US cases appear to be doing well.
