Definition
Measles is a highly contagious viral infection that primarily affects children. It causes fever, cough, runny nose, and a characteristic rash. In severe cases, it can lead to complications such as pneumonia or encephalitis.
Vaccination: Vaccination refers to the administration of a vaccine to stimulate the immune system and provide protection against specific diseases like measles.
Herd Immunity: Herd immunity occurs when a significant portion of the population is immune to a disease, making it difficult for the disease to spread within that community.
Complications: Complications are additional health problems that can arise as a result of an underlying condition. In the case of measles, complications may include pneumonia or encephalitis.
