Around 7-14 days after contracting the virus, patients generally develop fever, cough, runny nose and red eyes. Tiny white or bluish spots called Koplik’s Spots may appear inside the cheeks of the mouth a few days later. This is followed 3 to 7 days later by a red blotchy skin rash, which usually spreads from the face to the rest of the body. The rash usually lasts 4 - 7 days, but can persist for up to 3 weeks, leaving the patient with brownish staining and sometimes fine skin peeling.
In severe cases, lung, intestine and brain can become involved and lead to serious consequences or even death.
