Measles or rubeola, is a viral infection of the respiratory system. Measles is an infectious disease that spreads by contact with infected mucus or saliva. An infected person can spread the infection in air by coughing or sneezing. Once infected, the virus multiples at the back of throat and in the lungs. It then spreads throughout the body. Signs and symptoms of measles treatment are fever, tiredness, cough, sore throat, runny nose, sore eyes, photophobia (discomfort when looking at light), etc. The typical time between the exposure to a person infected with measles and the development of the initial symptoms (incubation period) is 10-12 days (the range is 7 to 21 days). The rash occurs a few days after the initial symptoms (ranges from 7 to 18 days from exposure). There is no specific antiviral measles treatment. Complications may require antibiotic treatment. Treatment for the symptoms includes plenty of fluids and paracetamol for the fever. Aspirin should not be given to children under 12 years of age unless specifically recommended by a general physician. Measles in adults is fairly common and is more likely to be worse for patients who have weak immune systems, such as those with HIV/AIDS or leukemia, those with vitamin deficiency. A person who has had measles before does not become infected again, cases of re-infection are very rare. However, anyone who has never been infected or vaccinated and breathes in infected droplets or is in close physical contact with an infected person, is likely to become ill. Children should receive the MMR (Mumps, Measles, Rubella) vaccine when they are between 12 and 15 months of age, and then again (a booster) before entering school when they are 4-6 years old.
