However, a recent outbreak of measles has affected at least 50 people in Washington state.
Measles was considered eradicated in the U.S.in 2000, as a result of immunization, but over the last few years more and more cases have been reported in Texas and other states.
Measles is a highly contagious, airborne virus that can be spread through coughing and sneezing.
DCPH is now in the process of identifying and contacting people who may have been exposed to the virus and this case has not been linked to any other measles cases.
Measles infections hit decade high in Europe
Almost 500 adults were vaccinated in the first week of February, up from an average of 176 in the years before. Five of the cases involved young children, some of whom received one round of the two-part vaccine.
Dr. Peter Hotez, an infectious disease specialist at Baylor College of Medicine and Texas Children's Hospital, said measles peaks in the late winter or early spring. A New York Department of Health official confirmed to ABC News last week that there were 30 confirmed cases to date in New York so far this year, and 122 confirmed cases in 2018.
"Measles is so contagious that if one person has it, 90 [percent] of the people close to that person who are not yet immune could become infected", the release read.
Three were reported in Harris County and one was reported in Galveston County by the counties' health departments. Children too young to be vaccinated or who have only had one dose of vaccine are more likely to get infected.
In January, 79 cases of measles were confirmed across 10 states, including Texas, according to the Centers for Disease Control and Prevention (CDC). Measles starts with fever, runny nose, cough, red eyes, and sore throat followed by a rash that spreads over the body.
Children should receive measles vaccination via one dose of MMR (measles, mumps, rubella) when they are 12 to 15 months old and another dose before entering school when they are between 4 to 6 years old, according to the health department.
