Why are measles a public health issue?

Measles is a public health issue due to its highly contagious nature, with a transmission rate significantly higher than many other Infectious Diseases. It can lead to severe complications, including pneumonia, encephalitis, and death, particularly in unvaccinated populations and vulnerable groups such as infants and those with weakened immune systems. Additionally, outbreaks can strain healthcare systems and lead to increased healthcare costs. Vaccination is crucial for preventing measles and protecting community health through herd immunity.
