Exposure guidance and symptom monitoring
Metro Health and HCHD released the following guidance for people who were at any of the listed locations listed above during the specified times:
- Review their immunization and medical records to determine if they are protected against measles infection. People who have not had measles infection or received measles immunization previously may not be protected from the measles virus. It is recommended to talk with a health care provider about receiving measles, mumps and rubella (MMR) immunization.
- Contact and notify their health care provider as soon as possible about a potential exposure if they are pregnant, have an infant, or have a weakened immune system regardless of vaccination history.
- Monitor themselves for illness with fever and/or an unexplained rash from four days to 21 days after their exposure (the time period when symptoms may develop).
- If symptoms develop, stay at home and avoid school, work and any large gatherings. Call a healthcare provider immediately. Do not enter a health care facility before calling and making them aware of your measles exposure and symptoms. The health department can assist healthcare providers in appropriately diagnosing and managing your care.
“Measles is a highly contagious virus that can lead to serious complications, especially in young children and individuals with weakened immune systems. If you think you may have been exposed or are showing symptoms, please contact your healthcare provider immediately” said Metro Health Deputy Director, Dr. Anita Kurian.
“Individuals who have not been vaccinated are at greater risk of infection,” said Hays County Local Health Authority John Turner, MD. “To minimize the risk of infection and serious illness, individuals should make sure they are vaccinated.”
The virus can stay in the air and on surfaces for up to two hours, even if the infected person has left, according to HCHD.

A person who is infected with measles can also spread the disease for up to four days before and after a measles rash appears, HCHD said. Anyone who breathes contaminated air or touches an infected surface, and then touches their eyes, nose or mouth, can become infected.
Common symptoms for measles include:
- High fever up to 105 degrees
- Cough
- Runny nose
- Red and watery eyes
- Tiny white spots that may appear inside the mouth two to three days after symptoms begin
- A rash three to five days after other signs of illness. The “measles rash” typically starts at the face and then spreads down to the rest of the body.
Anyone who has symptoms is urged to contact their primary care provider, an Urgent Care or an emergency room to set up an appointment and quarantine for four days after the onset of a rash.
HCHD will contact people who are known to have been in contact with the Gaines County resident to provide guidance and conduct case investigations.
“HCHD, DSHS and other local health agencies are working closely together to investigate the potential contacts,” the release said.
According to HCHD, 90% people who are not vaccinated or have not had a previous measles infection will become infected with the virus.
How can measles be prevented
HCHD said measles can be prevented with a measles, mumps and rubella vaccine (MMR). The MMRV vaccine protects against the same diseases, along with varicella, also known as chickenpox.
The vaccines are administered in two doses and are highly effective, according to HCHD.
Two doses are 97% effective against measles and one dose is 93% effective, HCHD said. An outbreak can be prevented if a community’s two-dose coverage of the vaccine remains at 95% or above.
As of Friday, the DSHS has confirmed 90 measles cases across seven counties since late January.

Fifty-seven of those cases are out of Gaines County, and many of the infected people are school-age children, according to department’s website.
In the release, Hays County Judge Ruben Beccera said he will work with HCHD and the Office of Emergency Services to offer additional resources.
“The Hays County Health Department is acting with haste to ensure the readiness and preparedness of partner agencies in response to this notification,” Beccera said. “The county has taken great strides to improve our response to public health emergencies. I am confident that the department will be capable of minimizing the impact of a potential measles outbreak in our county.”
