Zika is a mosquito-borne virus that can cause fever, rash, muscle and joint aches and red eyes (conjunctivitis). Symptoms are usually mild, and most people exposed to Zika virus won’t develop any symptoms at all. Zika has also been linked to a birth defect called microcephaly and other poor pregnancy outcomes in babies of mothers who were infected with the virus while pregnant.

The Texas Department of State Health Services continues to prepare for the possible transmission of Zika virus in Texas by emphasizing how people can protect themselves, increasing the state’s capacity to test for the virus, and working with local governments to assess mosquito control capabilities and activities.

Because the virus spreads from place to place through human travel, DSHS encourages people to follow travel precautions for countries and regions where Zika virus transmission is ongoing. That generally includes Latin America, the Caribbean and some Pacific islands. DSHS recommends travelers avoid mosquito bites while abroad and for 21 days after returning, in case they have been exposed to the virus.

People everywhere can protect themselves from mosquito bites and the threat of Zika by taking a few simple steps:

  • Apply EPA-registered insect repellents.  
  • Wear pants and long-sleeved shirts that cover exposed skin.  
  • Use screens or close windows and doors to keep mosquitoes out of your home.  
  • Remove standing water in and around your home.  
  • Cover trash cans or containers where water can collect.

West Nile in Texas – September 20, 2016

Even with cooling temperatures, West Nile illness continues to spread in Texas causing at least 144 cases of illness and two deaths in 2016. People should reduce their risk of exposure to the mosquito-borne virus that causes it by eliminating standing water and other mosquito breeding areas and avoiding mosquito bites.

As many as 80 percent of people who contract the virus will have no symptoms at all. Almost all others will have West Nile fever with symptoms like headache, fever, muscle and joint aches, nausea and fatigue. A very small minority will develop West Nile neuroinvasive disease, a life threatening illness that can cause neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis.

In 2015, there were 275 human cases of West Nile illness in Texas, including 16 deaths.
