Measles is a respiratory disease caused by the spread of the measles virus, which is prevalent in the winter and spring seasons. When a measles patient coughs or sneezes, droplets containing the measles virus are discharged into the air, and susceptible persons are infected by inhaling droplets containing the virus or through the conjunctiva of the eyes, and close contacts can also be transmitted by hands contaminated with the virus. The typical symptoms of measles virus infection are a fever for three days, a fever for three days, and a fever for three days. The initial symptoms of measles are fever, cough, bloodshot eyes, eye droppings, about three days later, a rash will first appear from behind the ears and neck, the rash begins as a sparse irregular red papule, generally not itchy, and then spreads along the edge of the hair, and within 24 hours develops downward throughout the trunk and upper extremities, mostly on the third day the rash involves the lower extremities and the palms of the hands and feet, the skin between the rash is normal. The rash is often accompanied by a high fever that does not subside. It is important to note that the entire course of measles is about ten days, and the main serious risk to the body is the complications that arise after measles.
