Measles is a very contagious viral illness. After exposure, one or two weeks pass before the first cold-like symptoms show up.
During this period, the disease is most contagious, although it can be spread until the fever and rash are completely gone — after about five to eight more days.
Infected children usually pass measles to others (including non-immunized adults and children) via coughing or sneezing.
There’s no specific treatment for measles, but you can take steps to ease your child’s discomfort. Typically there are few complications.
Very rarely, measles can trigger encephalitis, an inflammation of the brain.
