HOUSTON, Texas (KTRK) -- Harris County officials announced a preparedness plan Tuesday as concerns grow over the spread of measles.
Judge Lina Hidalgo's office said that includes updates on vaccination locations.
It comes after the commissioner for the state's health department, Dr. Jennifer Shuford, noted during a legislative hearing on Monday that the measles case count has increased to at least 158 in the west Texas outbreak.
On Tuesday, the health department confirmed 159 cases have been reported in Texas, and 22 people have been hospitalized.
Last week, officials said a school-aged child in the outbreak area died, marking the first measles death in the U.S. in a decade. The child was not vaccinated.
So far, no positive tests have been reported in the Houston area.
"For every one person infected with measles, if they were going to go into a room full of people that were unvaccinated, you could expect 12 - 15 of those people to become infected. It's extremely contagious," Dr. David Persse, City of Houston Chief Medical Officer, said.
Persse said the virus can hang in the air for a couple of hours.
Symptoms include:
