Measles is a respiratory infection that spreads through coughing or sneezing. It causes symptoms, like fever, cough, runny nose, and watery eyes. About two to three days after the onset of these symptoms, tiny white spots typically appear inside the mouth (Koplik spots), followed by a red blotchy rash that spreads from head to toe. And as much as it can be dangerous for children younger than 5 and adults older than 20, measles is also a serious illness for pregnant women.
