The Cleveland Clinic notes that there is no cure for measles, and measles just has to "run its course." However, the best protection from it is a measles vaccine, which is typically given to babies in the form of the MMR (measles, mumps and rubella) vaccine.

Measles is spread through contact with infected nasal or throat secretions, or by breathing in the virus after it's coughed, sneezed or sent into the air by an infected person, according to WHO. The measles virus can remain contagious in the air or on contaminated surfaces for up to two hours.
