Cyclospora – Sept. 17, 2018

DSHS and local health departments around the state are investigating an increase in the number of reported cases of the Cyclospora parasite beginning in early May. Long-lasting illnesses caused by the parasite, with symptoms like watery diarrhea, loss of appetite and fatigue, have been seen in various parts of the state and have prompted public health experts to advise health care providers and the public to be aware of the symptoms and pursue testing when needed.

Past outbreaks have been associated with imported fresh produce, and disease investigators are busy gathering information about the current illnesses as they attempt to determine whether there is a common source for the current outbreak. DSHS will update the 2018 count of Cyclospora cases here on Mondays during the outbreak. More information is available in the DSHS news release:

West Nile – Sept. 18, 2018

In mid-July, DSHS confirmed the first three cases of West Nile illness in the state this year. We’ll continue to update case counts weekly here each Tuesday.

In 2017, Texas reported 135 cases of West Nile illness that resulted in six deaths.

People can be infected by West Nile virus through the bite of an infected mosquito. People should prevent bites by applying insect repellent while outdoors, using air conditioning or making sure screens are in good repair, and covering up with long sleeves and long pants to prevent bites. It’s also important to dump out standing water to keep mosquitoes from laying eggs.

Zika Virus – Sept. 18, 2018

DSHS provides updates every Tuesday on the number of Zika virus disease cases in Texas by the patient’s county of residence. DSHS has confirmed three Zika cases for all of 2018, all acquired outside the United States. Full data for previous years is available at TexasZika.org.

2018 Zika cases by county

Collin - 1 
Williamson - 2

All 2018 cases are associated with travel.

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.

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.
