The CDC said that at least eight other states have reported cases of the measles in 2019: California, Colorado, Connecticut, Georgia, Illinois, New Jersey, New York and Oregon.
"Measles is a highly contagious respiratory disease caused by a virus, which spreads to others through coughing and sneezing", Umair Shah, the executive director of Harris County Public Health said in a statement confirming the new cases in Houston.
In 2013, 27 cases of measles were reported in Texas; 16 of the 27 confirmed cases were in Tarrant County, according to the DSHS.
Measles is highly contagious, and if one person has it, 9 out of 10 people around that person will also become infected if they're not yet vaccinated.
The health department did not say where specifically the case was in order to protect patient confidentiality. A New York Department of Health official confirmed to ABC News last week that there have been 30 established circumstances to this point in New York so far this year, and 122 confirmed instances in 2018.
Symptoms of measles include fever, cough, red eyes, sore throat and a rash that spreads all over the body.
"If you feel like you're experiencing symptoms and signs of a measles infection, contact your health provider", Marlow said. Yet one or two out of every 1,000 children who get measles will die from complications, according to the CDC.
Vials of the measles, mumps and rubella vaccine are displayed on a counter at a Walgreens pharmacy in Mill Valley, California, on January 26, 2015.
In 2017, Texas Health and Human Services released its report of student vaccinations, showing overall Texas schools reported high rates of coverage for each vaccine but kindergarten students reported slightly lower coverage due to personal beliefs.
DSHS and the Centers for Disease Control and Prevention recommend children get a dose of the measles vaccine at 12-15 months of age and again at 4-6 years.
