Texas Announces Local Zika Virus Case in Rio Grande Valley

___

Response Underway; Will Include Increased Surveillance

The Texas Department of State Health Services and Cameron County Department of Health and Human Services today announced the first case of Zika virus disease likely transmitted by a mosquito in Texas. DSHS is supporting Cameron County’s response to the case and to the ongoing risk of Zika in the community.

The patient is a Cameron County resident who is not pregnant and who was confirmed last week by lab test to have been infected. She reported no recent travel to Mexico or anywhere else with ongoing Zika virus transmission and no other risk factors.

Laboratory testing found genetic material from the Zika virus in the patient’s urine, but a blood test was negative, indicating that the virus can no longer be spread from her by a mosquito. There are no other cases of suspected local transmission at this time, but health officials continue to conduct disease surveillance activities as part of the state's ongoing Zika response.

“We knew it was only a matter of time before we saw a Zika case spread by a mosquito in Texas,” said Dr. John Hellerstedt, DSHS commissioner.

“We still don’t believe the virus will become widespread in Texas, but there could be more cases, so people need to protect themselves from mosquito bites, especially in parts of the state that stay relatively warm in the fall and winter.”

Cameron County, DSHS and the Centers for Disease Control and Prevention are working together to investigate and respond to the case.

Further investigation will be necessary to attempt to pinpoint how and where the infection occurred, and health officials are also responding in a number of other ways.

DSHS has activated the State Medical Operations Center to support the response and is providing expertise, personnel and equipment for activities from disease investigation to mosquito surveillance to public education.

With DSHS support, Cameron County and the City of Brownsville have conducted an environmental assessment at the patient’s home and have been trapping and testing mosquitoes to learn more about activity in the area.

Brownsville has recently sprayed for mosquitoes in the area and will continue to take action to reduce the mosquito population.

Health workers from Cameron County and DSHS will be going door to door in the area around where the case lived beginning this evening to educate the public about Zika, help people reduce potential mosquito breeding habitat on their property, and collect voluntary urine samples to determine whether other infections are present.

The samples collected will be tested at the DSHS laboratory in Austin.

The DSHS regional office in Harlingen has delivered laboratory supplies, boxes of educational materials and mosquito traps to Cameron County and will continue to assist in the response. Additionally, state and local public health has been in communication with CDC, which is providing additional assistance and expertise.

Travel back-and-forth across the border is a way of life in the Valley, and news reports from Mexico indicate Zika transmission by mosquitoes in multiple communities on the Mexican side of the border.

Due to the risk of birth defects associated with Zika, pregnant women should avoid traveling to Mexico and should avoid sexual contact or use condoms with partners who have traveled there.

Other precautions include:

  • Using EPA-approved insect repellent.
  • Wearing long pants and long-sleeved shirts that cover exposed skin.
  • Using air conditioning or window and door screens that are in good repair to keep mosquitoes out of homes.
  • Removing standing water in and around homes, including water in trash cans, toys, tires, flower pots and any other container that can hold water.

Zika virus is transmitted to people primarily through the bite of an infected mosquito, though sexual transmission can occur. The four most common symptoms are fever, itchy rash, joint pain and eye redness. While symptoms are usually minor, Zika can also cause severe birth defects, including microcephaly, and other poor birth outcomes in some women infected during pregnancy.

DSHS is again asking health care providers to consider Zika virus infection in their patients and order the appropriate testing. DSHS recommends testing all pregnant women who have traveled to areas with active Zika transmission during their pregnancy. DSHS also recommends testing pregnant women who have two or more of the typical Zika symptoms in Cameron, Hidalgo, Starr, Webb, Willacy or Zapata counties without travel history, and anyone with at least three symptoms statewide.

Through last week, Texas has had 257 confirmed cases of Zika virus disease. Until now, all cases had been associated with travel, including two infants born to women who had traveled during their pregnancy and two people who had sexual contact with infected travelers.

Additional information on cases and for the public is available at www.texaszika.org.
