Measles: A Highly Contagious and Preventable Disease
Measles remains a critically important global health threat, despite the availability of a safe and effective vaccine. This highly contagious viral disease can lead to severe illness, complications, and even death, particularly in young children.Understanding the risks, symptoms, and preventative measures is crucial for protecting individuals and communities.
What is Measles?
Measles is a highly contagious infection caused by a virus. It spreads easily through the air when an infected person breathes, coughs, or sneezes [[1]]. It’s so contagious that if one person has it, 90% of the people close to that person who aren’t immune will also become infected.
Symptoms of Measles
The initial symptoms of measles typically appear 10-14 days after exposure to the virus and include:
- High fever (often above 104°F)
- Cough
- Runny nose
- Red, watery eyes (conjunctivitis)
- Small white spots inside the mouth (Koplik’s spots)
These are followed by a rash that usually begins on the face and spreads down the body. The rash can last for up to a week.
Serious Complications
While measles is frequently enough considered a childhood illness, it can lead to serious complications, especially in young children, pregnant women, and individuals with weakened immune systems. These complications can include:
- Pneumonia
- Encephalitis (inflammation of the brain)
- Ear infections
- Diarrhea and dehydration
- Subacute sclerosing panencephalitis (SSPE), a rare but fatal brain disorder that develops years after a measles infection
In 2018, over 140,000 people died from measles globally, the majority of whom were children under the age of five [[2]].
Transmission and Risk Factors
Measles is spread through direct contact with an infected person or through the air via respiratory droplets produced by coughing or sneezing. Individuals at highest risk include:
- Unvaccinated individuals
- Young children
- Pregnant women
- People with weakened immune systems
- Individuals traveling to areas with ongoing measles outbreaks
Prevention: The Power of Vaccination
The most effective way to prevent measles is through vaccination. The measles, mumps, and rubella (MMR) vaccine is highly effective, providing two doses offer over 97% protection [[3]]. The World Health organization (WHO) recommends two doses of the MMR vaccine for all children.
Global Efforts and Current Status
Before widespread vaccination in 1980, measles caused more than 2 million deaths each year. While significant progress has been made, measles outbreaks still occur in many parts of the world, often in areas with low vaccination rates. The WHO and its partners are working to eliminate measles globally through increased vaccination coverage and improved surveillance.
Frequently Asked Questions (FAQ)
- Can adults get measles? Yes, adults who were never vaccinated or who only received one dose of the MMR vaccine are susceptible to measles.
- Is measles more contagious than COVID-19? Yes, measles is considered more contagious than COVID-19.
- What should I do if I suspect I have measles? Contact your healthcare provider promptly. It’s important to avoid contact with others to prevent further spread.
