If you've heard of measles, you may associate it with images of red, spotty rashes and childhood illness.

Measles is indeed a highly contagious and potentially severe disease caused by the measles virus. While its incidence has decreased dramatically due to widespread vaccination, it still poses a threat, especially in communities with low vaccination rates. Let's dive deeper to understand this infectious disease.

What is Measles?

Measles, or Rubeola, is a highly infectious viral disease that primarily affects children. However, unvaccinated individuals of any age group can contract the disease. Measles is known for its characteristic red rash, but it also causes a range of other symptoms that can lead to severe complications, especially in adults and people with compromised immune systems.

How is Measles Transmitted?

Measles is primarily transmitted through direct contact and airborne transmission when an infected person coughs or sneezes. The virus can live for up to two hours in an airspace where the infected person coughed or sneezed, meaning that measles can spread without direct person-to-person contact.

What are the Symptoms of Measles?

Symptoms typically appear 10 to 14 days after exposure to the virus. Early signs of measles include fever, dry cough, runny nose, sore throat, inflamed eyes (conjunctivitis), and tiny white spots inside the mouth (Koplik's spots). Later, a skin rash develops, usually spreading from the face to the rest of the body.

What are the Complications of Measles?

While many people recover from measles within 2 to 3 weeks, some may develop serious complications, particularly those with weak immune systems. These complications can include pneumonia, encephalitis (a potentially deadly brain swelling), and a rare long-term disease called subacute sclerosing panencephalitis (SSPE), which can be fatal. Moreover, measles can cause pregnancy complications like premature birth or low birth weight.

How is Measles Treated?

There is no specific antiviral treatment for measles. Management of the disease focuses on relieving symptoms and guarding against complications. This can include rest, hydration, and over-the-counter medications to manage fever. Hospitalization may be required for severe cases.

Prevention is Key: The MMR Vaccine

The best way to prevent measles is through vaccination with the Measles-Mumps-Rubella (MMR) vaccine. The vaccine is highly effective and provides long-lasting protection. The World Health Organization recommends two doses: the first at 9 to 12 months and the second at 15 to 18 months.

The Power of Herd Immunity

When a large proportion of a population is vaccinated, it creates 'herd immunity,' protecting those who cannot be vaccinated, such as infants and those with compromised immune systems. However, if vaccination rates drop, the virus can quickly spread, leading to outbreaks.

Though measles may seem like a disease of the past, it remains a significant public health issue in some parts of the world and among unvaccinated populations. The key to preventing measles is widespread vaccination to achieve herd immunity. Public health initiatives must continue to focus on increasing vaccination rates and addressing vaccine hesitancy to protect our global community from the threat of measles.
