A Texas resident who traveled to Miami contracted Zika there, where local mosquitoes have transmitted the virus to 30 people as of Aug. 15.
Health officials linked the case to Miami by evaluating travel dates and symptom onset while taking into consideration the known local transmission occurring in the Floridian city.
In a statement, the Texas Department of State Health Services said, "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."
Excluding this case, there have been 108 cases of Zika reported in Texas related with travel to areas with active local transmission of the virus. Of these cases, three have occurred in pregnant women, resulting in two congenital Zika infections in infants. One of said infants was born with microcephaly and died shortly after birth.
To date, there have been no cases of Zika transmitted by local mosquitoes in Texas, though state health officials are on alert for such an occurrence.
As of Aug. 10, the CDC has confirmed nearly 2,000 cases of Zika in the U.S.
