CNN —A California medical facility is trying to contact about 300 people who were possibly exposed to measles after a child was treated for the contagious viral illness at a hospital in Sacramento last week, officials said. The child had returned from international travel and was evaluated March 5 at UC Davis Health’s emergency department between 12 p.m. and 5 p.m. The hospital said it “has the situation under control” and noted it began contacting about 300 in the facility who may have been exposed. Measles often begins with a mild to moderate fever, along with a cough, runny nose, and red/watery eyes, health officials detailed. A total of 45 measles cases have been reported in 17 states since the beginning of the year, according to the CDC.
