The Texas Department of State Health Services on Tuesday confirmed a case of chikungunya that was contracted in the state.
DSHS said a Cameron County resident got sick with the mosquito-borne illness in November 2015 and was diagnosed in January. The department added the case was not reported to the Cameron County health department until last month.
The Cameron County Department of Health and Human Services investigated and determined the patient had not traveled, and the Centers for Disease Control and Prevention confirmed the case last week.
Prior to this case, all Texas residents who contracted the illness were infected while traveling abroad. DSHS said the primary risk for infection remains related to travel, citing no chikungunya in local mosquitoes.
