A highly contagious viral disease that spreads through coughing, sneezing, and close contact with infected individuals. The disease commonly causes fever, cough, runny nose, red eyes, and a characteristic skin rash. Outbreaks often occur in areas with low vaccination coverage, allowing the virus to spread quickly among communities. Health authorities typically respond through vaccination campaigns, disease surveillance, public awareness efforts, and medical treatment to prevent further transmission and protect vulnerable populations, especially children.
