What is Measles?

Measles is a highly contagious viral infection caused by the measles virus. It is considered a childhood disease but can affect people of all ages if they are not vaccinated. The illness typically starts with flu-like symptoms such as fever, cough, and runny nose, followed by a characteristic red rash. Measles spreads through droplets in the air, making it especially dangerous in communities with low vaccination rates.

Causes and Spread of Measles

The measles virus spreads primarily through coughing or sneezing, releasing the virus into the air, which is then inhaled by others. A person can be contagious before the rash even appears. Children and unvaccinated adults are especially vulnerable, as measles can infect nearly everyone exposed to the virus without immunity. Thanks to vaccination programs, measles has declined in many countries, but regional outbreaks still occur.

Long-Term Effects of Measles

Measles is not only dangerous for its acute symptoms. Without treatment, it can lead to severe complications such as pneumonia, middle ear infections, and even encephalitis (brain inflammation). The disease can be life-threatening, especially in young children and individuals with weakened immune systems. Additionally, measles can weaken the immune system long-term, making people more susceptible to other infections. Therefore, vaccination is crucial in preventing the spread of the disease.
