Also known as rubeola or mobilli, it is a highly contagious infection of the respiratory system caused by a virus (commonly by paramyxovirus). The infection is often spread by coming in contact with droplets (due to sneezing, coughing) flown out of the nose, mouth, or throat of an infected person. People, who already had vaccination against the measles, are immune to it. Symptoms start to show after the 9-12 days incubation period, which include fever, muscle pain, bloodshot eyes and rash. Serology is adopted for diagnosis. As there is no specific treatment, bed rest and Tylenol are often suggested by the physicians.
