Measles can live in the air for two hours after a person who was infected leaves. Symptoms can appear seven to 14 days after coming in contact with measles, the CDC said. The measles virus causes rash, high fever, red eyes, runny nose and a cough.

It's not confirmed that measles parties are to blame for the outbreak in West Texas. But they are as dangerous as they sound.

As Texas continues to battle a growing measles outbreak largely among its unvaccinated children, six other states have confirmed cases, as well.
