Thus far, Florida is the only other state with homegrown cases of the disease. It typically causes only mild symptoms, at worst, but the disease is especially dangerous to pregnant women, as it can cause severe birth defects, including babies born with unusually small heads.
Here are some questions and answers about Zika:
HOW DOES ZIKA SPREAD?
Zika is transmitted to people primarily through the bite of an infected Aedes aegypti species mosquito, but it can also be spread during sex. Most infected people don't even have symptoms, but for those who do, it's usually a mild illness, with fever, rash and joint pain.
Even though it's late in the season, mosquitoes can still spread Zika in some areas of the country, said Dr. Tom Frieden, director of the Centers for Disease Control and Prevention.
Chris Van Deusen, a spokesman for the Texas Department of State Health Services, said that because of the warm conditions in South Texas, mosquitoes can be a concern year-round. But he noted that much of Texas is at the end of its mosquito season.
WHAT ARE THE DETAILS OF THE TEXAS CASE?
State health officials announced the Brownsville case on Monday, noting that testing showed that at this point, the virus can no longer be spread from her by mosquitoes.
Though Brownsville is on the Mexico border, the woman said she hadn't recently
Officials said further investigation is necessary to figure out how she was infected. But Van Deusen said the most likely scenario is that someone who got infected in an area where Zika is widespread
WHY DON'T AUTHORITIES THINK ZIKA WILL BECOME WIDESPREAD IN TEXAS?
One reason health officials don't think Zika will become widespread in Texas is because of the state's experience with dengue fever, Van Deusen said. He said the same mosquito species spreads both diseases, and that when there are dengue epidemics in Mexico, cases have spilled over to South Texas but haven't been widespread.
The mosquito likes to bite indoors, and the widespread use of screens and air conditioners in the U.S. keeps them out.
WHAT CAN YOU DO?
Experts say people need to protect themselves from mosquito bites, especially in areas that stay relatively warm in the fall and winter. That includes using insect repellent, wearing clothes that cover most skin, keeping mosquitoes out of homes and removing standing water where mosquitoes can breed.
Van Deusen said that at this point, there's no particular advisory for pregnant women in the Brownsville area, other than that they should be protecting themselves from mosquito bites.
WHAT'S THE HISTORY OF ZIKA IN TEXAS?
Through last week, Texas has had 257 confirmed Zika cases that were all associated with travel, including two infants born to women who
WHAT IS THE POSSIBILITY OF IT APPEARING IN OTHER STATES?
Van Deusen said a Zika case is possible anytime an area has the mosquito species that spreads the disease and residents who have been
A CDC map shows that in addition to being in the southern U.S., the range of the Aedes aegypti mosquitoes may extend into parts of the Midwest and as far north as New York and Connecticut.
HOW DO THINGS STAND IN FLORIDA?
Since people began contracting the Zika virus in the Miami area over the summer, there have been 240 such cases in Florida. Two areas have since been cleared as being part of the transmission zone, and it's still spreading in two other areas.
Florida Department of Health spokeswoman Mara Gambineri said there has been a decrease in the last few weeks in locally transmitted cases, and that while it doesn't get cold enough to eliminate all mosquitoes, there are fewer as it gets cooler.
