An outbreak of measles in Texas has infected 124 people so far — 18 of whom have subsequently been hospitalized and one who has died.

At least 124 cases of measles have been identified in Texas since late January, mostly among children and teenagers who are either unvaccinated or whose vaccination status is unknown, officials say.

The measles outbreak in Texas has now turned deadly. Texas and federal health officials have just reported the first deaths attributed to the still-growing outbreak, which has sickened over a hundred people.
