Measles is a highly contagious and potentially severe disease that causes fever, rash, cough and red, watery eyes. Measles spreads very easily by air and by direct contact with an infected person. People who become infected are contagious before they have symptoms and know they are infected.

Health officials also say to self-monitor for illness with fever and/or an unexplained rash from 7 days to 21 days after exposure. If symptoms develop, stay at home and call a health care provider immediately.

"The best way to protect yourself from measles is to get vaccinated. All children and non-immune adults should be vaccinated against measles," Long Beach Health Officer Anissa Davis said. "If you are unsure of your vaccination status, contact your provider to make sure you are up-to-date."
