The Bell County Health Department has said there are two other potential cases of measles pending as they wait for test results.
The children were not vaccinated nor did they complete their vaccine series.
The department said they are taking all precautionary measures to prevent the disease from spreading with five measles cases reported in Harris, Montgomery and Galveston country earlier this week.
Measles is an airborne disease which is highly contagious, but it is preventable. Symptoms include a fever, a dry cough, a runny nose, a sore throat and inflamed eyes.
Anyone with these symptoms, especially pregnant or nursing, should be evaluated by a physician.
