A Texas resident who recently traveled to an area of Miami with local Zika transmission has tested positive for the virus. The traveler, an El Paso County resident, recently returned from the area and sought testing after becoming ill.

This is the first Texas case to be linked to travel within the continental United States. The case will be classified as “travel-associated” and is being investigated for more details.

Health officials linked this case to Miami travel after closely evaluating travel dates, symptom onset date and known local transmission of Zika virus in Miami. This will be El Paso County’s first Zika case, and the county has found no other evidence of the virus or local transmission.

Excluding this case, Texas has reported 108 cases associated with travel to areas with active Zika transmission. This count includes three pregnant women, two infants infected before birth, and one person who had sexual contact with a traveler.

There have been no reported cases of Zika virus disease transmitted by mosquitoes in Texas, but Texas is on alert for the possibility of local transmission. State efforts have been underway since January to delay and minimize the impact of Zika on Texas.
