A case of measles has been confirmed in an Orange County resident, an unvaccinated toddler, who had recently traveled domestically. The Orange County Health Care Agency's Communicable Disease Control Division (CDCD) is reaching out to identified contacts.
Measles is an acute viral illness typically presenting with fever, cough, coryza, and conjunctivitis, followed 3-5 days later by a rash. The maculopapular rash typically begins on the face and spreads down the torso and out to the extremities. The incubation period for measles ranges from 7-21 days after exposure, and individuals are infectious from 4 days prior to rash onset until 4 days after rash onset. Measles is highly contagious and spreads via airborne transmission.
Individuals are presumed to be immune to measles if they were 1) born prior to 1957 OR 2) have received two doses of measles-containing vaccine OR 3) have a documented positive IgG titer OR 4) documentation of prior disease. More info...
