This year we have the second highest outbreak of measles in a decade. The likely cause is foreign travel to places in which measles is still endemic then returning to an America where the unvaccinated rate is increasing. We had declared measles eradicated in the U.S in the year 2000. It has made a comeback. Symptoms include eye discharge, fever, and a characteristic rash. It is very contagious. If you feel you have it, see your doctor quickly and practice self quarantine. Post exposure vaccination is helpful. In the long run, we have to educate people that vaccination is critical and the risks rare.
