WATCH| Measles cases nearing 30-year high
Current measles activity continues to be associated with exposure to the virus during international travel and subsequent spread among unvaccinated individuals.
Measles symptoms typically develop seven to 14 days after exposure but can take up to three weeks to develop. Early symptoms include fever, cough, runny nose and red eyes. A red rash usually appears three to five days after the initial symptoms start.
A person with measles is contagious from four days before the rash appears through four days after it begins. The virus can live in the air or on surfaces for up to two hours and be transferred to the nose or mouth by touching infected surfaces.
There is no specific treatment for measles. Supportive care such as rest, fluids and fever-reducing medications is recommended. Complications can include ear infections, pneumonia, and, in rare cases, death.
