Notifiable Conditions FAQs

Measles is a highly contagious respiratory virus. A measles outbreak is considered a public health emergency and should not be taken lightly. It is one of the most contagious infectious diseases.

Providers can report flu, COVID-19, and RSV cases online through the Provider Reporting Dashboard.

The Texas Health and Safety Code mandates the reporting of suspected or laboratory-confirmed notifiable conditions by health care providers, hospitals, laboratories, schools, daycares, long-term care facilities, and other specified organizations.

Common Questions on Disease Prevention

You can reduce the risk of respiratory infections by getting vaccinated, avoiding close contact with sick individuals, covering your coughs and sneezes with a tissue or your elbow, washing your hands frequently, and staying home if you’re feeling unwell. Return to daily activities only after being fever-free for 24 hours with improving symptoms. For more flu prevention tips, visit the CDC Flu Information Page.

Good hygiene and food safety practices are key. Wash your hands with soap and water for at least 20 seconds, especially before meals and after using the bathroom. Cook food thoroughly, avoid eating undercooked meats or eggs, wash fruits and vegetables before eating, and avoid consuming raw milk or eggs. Learn more from the CDC Handwashing Guide and Global Hygiene Council.

Vaccination is the most effective prevention method. In addition, avoid contact with infected individuals, cover your mouth when coughing or sneezing, wash your hands frequently, and follow your doctor’s antibiotic prescription if diagnosed with pertussis. More information is available from the CDC Pertussis Guide.

Reduce mosquito exposure by avoiding outdoor activities at dawn and dusk, using EPA-registered insect repellent, wearing long sleeves and pants, and eliminating standing water near your home. Visit the CDC West Nile Virus Information Page for more details.

If you are Hepatitis B positive, ensure your healthcare provider is aware. Your newborn should receive the hepatitis B vaccine and a dose of HBIG within 12 hours of birth to prevent transmission. The Perinatal Hepatitis B Prevention Program provides additional resources to protect your baby.

The Perinatal Hepatitis B Prevention Program is available through Public Health to help prevent the transmission of Hepatitis B from mother to newborn during delivery.

The program manages care for hepatitis B surface antigen (HBsAg) positive pregnant women through delivery and ensures that their newborns receive the necessary immunizations and follow-up testing to protect against the virus.

Identify the animal for quarantine or rabies testing, wash the wound thoroughly with soap and water, and seek medical attention as wounds may become infected. Rabies prophylaxis may be necessary. Contact your Local Rabies Control Authority (LRCA) for further guidance. Visit Animal Management & Welfare for more information.

Common Questions on Measles

Measles is a highly contagious respiratory virus. A measles outbreak is considered a public health emergency and should not be taken lightly. It is one of the most contagious infectious diseases.

People who have received zero or only one dose of the MMR vaccine are at the highest risk of contracting measles.

Infants and children younger than five years old, adults older than 20 years old, pregnant individuals, and those with compromised immune systems.

The CDC considers you protected from measles if you have written documentation (records) showing at least one of the following:

You received two doses of a measles-containing vaccine and are:

  • A school-aged child (grades K-12).
  • An adult in a high-risk setting for measles transmission, such as college students, healthcare workers, and international travelers.

 

You received one dose of a measles-containing vaccine and are:

  • A preschool-aged child.
  • An adult who is not in ahigh-risk setting for measles transmission.

 

A laboratory-confirmed test shows you had measles at some point in your life.

A titer result confirms you are immune to measles.

You were born before 1957.

If your provider recorded your vaccinations in the state vaccination system, ImmTrac, the health department may be able to help. However, most adults are not in ImmTrac since it is an “opt-in” system. You can visit your local health department to request a vaccination record free of charge — no appointment necessary. Bring a valid ID. You can also contact your primary care provider to check your vaccination record if they use ImmTrac. Without written documentation of measles vaccination, you are considered unvaccinated.

It means you have received only one of the two required doses of the measles vaccine.

No.

No.

Adults born after 1957 who have not received two doses of MMR or had measles should get vaccinated. This is especially important if you:

  • Attend school beyond high school.
  • Work or volunteer in a healthcare facility.
  • Travel internationally, including on cruise ships.
  • Are of childbearing age (and are not currently pregnant).

No, pregnant individuals should not receive the MMR vaccine. Talk to your OB/GYN for more information on how to protect yourself.

Yes, it is safe for breastfeeding individuals to receive the MMR vaccine. Breastfeeding does not interfere with the response to the vaccine, and the baby will not be affected through breast milk.

Follow the recommended vaccination schedule:

  • First dose at 12-15 months of age.
  • Second dose at 4-6 years of age.

 

Guidance may change during an outbreak and will be adjusted if necessary.

Immediately isolate yourself from others. Contact your healthcare provider by phone to arrange testing in a way that minimizes exposure to others. Do not go to your doctor’s office unannounced. Watch for symptoms, which typically develop 7 to 21 days after exposure.

Monitor yourself for measles symptoms for 21 days after exposure.

Yes, though it is rare. About 3 out of 100 people who receive two doses of the measles vaccine may still get measles if exposed. However, fully vaccinated individuals tend to have a milder illness and are less likely to spread the disease.

Anyone who has shared the same airspace with an infectious person is considered a close contact.

Anyone in the same room as a suspected case, regardless of time spent, is considered exposed.
Measles can remain in the air and on surfaces for up to two hours after an infectious person has left.
The infectious period is four days before rash onset through four days after rash onset (day of rash onset is day 0).

There is no minimum exposure time. However, the longer you are around an infectious person, the greater your chance of becoming infected.

Post-exposure prophylaxis must be given quickly and within a specific time frame. Identifying close contacts helps protect them from infection.

  • About 10% of individuals who receive the measles vaccine develop a fever and rash about one week after vaccination.
  • If you received the measles vaccine 6-45 days before the rash, a positive IgM test does not necessarily mean you have measles.
  • A negative IgM test, however, rules out measles.
  • If you were vaccinated more than 14 days before illness onset, a viral specimen should be collected to confirm the rash is due to measles.
  • Testing is not recommended for those vaccinated 6-14 days prior to rash onset unless they were exposed to a confirmed case.

No. Vaccine virus transmission does not occur from a vaccinated person, even in those who develop a rash. Person-to-person transmission of the vaccine virus has never been documented.

There are multiple exclusion scenarios:

  • Confirmed measles case: The individual must stay home and avoid public places until four days after the rash begins and they are well enough to return.
  • Unvaccinated individuals: If they receive one dose of the MMR vaccine within 72 hours of exposure, they can return immediately. A second dose is required 28 days later. If they do not get vaccinated within 72 hours, they must isolate at home for 21 days.
  • Unvaccinated individuals refusing the MMR vaccine: Must stay home for 21 days after exposure. If exposed to multiple cases, the exclusion period extends.
  • Individuals with one dose of MMR: A second dose should be given immediately if 28 days have passed since the first dose. No additional quarantine is required.
  • Fully vaccinated individuals: Should monitor for symptoms for 21 days after exposure.

 

The Texas Administrative Code (TAC) Rule §97.7 requires schools to exclude all exposed students without documentation of two measles vaccine doses or proof of immunity for at least 21 days after the last exposure.

Measles is highly contagious and spreads through the air when an infected person coughs or sneezes. If one person has measles, 9 out of 10 unvaccinated people around them will also become infected.

Common complications include diarrhea and ear infections. Severe complications include pneumonia, encephalitis (brain swelling), hospitalization, pregnancy complications, and even death.

Routine cleaning of hard surfaces with a viricidal cleaner is recommended, especially during flu, RSV, and COVID seasons. If a measles case is suspected, avoid entering the space for at least two hours after the infected person has left.
