Measles is a highly contagious viral infection that causes a characteristic skin rash, high fever, cough, runny nose, and red, watery eyes. Spread through airborne droplets released when an infected person coughs or sneezes, measles can lead to serious complications, especially in young children and immunocompromised individuals, including pneumonia, encephalitis (brain swelling), and even death. While a highly effective vaccine is available, measles remains a significant public health concern in areas with low vaccination rates. Early diagnosis and supportive care are crucial for managing the illness and preventing its spread.
