Understanding the Measles Threat

It’s important to know about measles to stop it from spreading. This disease is very contagious and can cause serious problems, mainly for those who haven’t been vaccinated.
How Measles Spreads: Transmission Facts
Measles spreads when someone who has it breathes, coughs, or sneezes. The virus can stay in the air for up to two hours. About 90% of people who haven’t been vaccinated and get exposed will get measles. This shows how big a risk it is for those who can’t get the vaccine.
Measles is contagious in a few ways:
- Direct contact with someone who has it
- When someone with measles coughs or sneezes, spreading it through the air
- On surfaces, but the virus doesn’t last long outside a body
Current Outbreaks: Global and US Statistics
Measles is a big worry worldwide, with 395,521 confirmed cases in 2024 in 59 countries. In the US, the first 16 weeks of 2025 saw 800 cases. This is the second most in 25 years.
Some important facts about the outbreaks are:
- Measles cases have gone up a lot globally, with many countries facing outbreaks.
- In the US, cases are rising, with reports from different states.
- People who can’t get vaccinated, like unvaccinated kids and those with weak immune systems, are getting sick more often.
How to Avoid Measles Through Vaccination

To protect against measles, it’s key to understand the MMR vaccine. The MMR vaccine is vital in stopping measles. It protects not just the person but also others by stopping the disease from spreading.
MMR Vaccine Schedule and Effectiveness
The MMR vaccine comes in two doses. The first is given to kids at 12 to 15 months. The second is given at 4 to 6 years old. Two doses of the MMR vaccine are about 97% effective against measles. This makes it a strong way to prevent the disease.
Who Should Get Vaccinated and When
Anyone not vaccinated against measles or unsure of their status should get vaccinated. This includes kids, teens, and adults who haven’t had the MMR vaccine. It’s very important for healthcare workers and travelers to get vaccinated.
Checking Your Immunity Status
If you’re not sure if you’re immune to measles, a blood test can check. This is good for those traveling to measles areas or working in healthcare. Getting the recommended two doses of the MMR vaccine is the best way to know you’re immune.
Additional Protection Strategies During Outbreaks
When measles outbreaks happen, we need to act fast to stop it from spreading. We must protect those who are most at risk, keep public places safe, and know what to do if we get exposed.
Protecting Vulnerable Populations
Groups like young kids, pregnant women, and people with weak immune systems face a big risk from measles. To keep them safe, we suggest:
- Make sure they’re up-to-date on their MMR shots
- Stay away from anyone with measles
- Don’t go to public places during outbreaks
Hospitals are key in stopping measles by isolating sick patients and making sure staff are vaccinated.
Preventing Exposure in Public Settings
To avoid measles in public, we should:
- Stay away from crowded spots and big gatherings during outbreaks
- Wear masks to help stop the virus from spreading
- Wash your hands often
By following these steps, we can lower the chance of measles spreading in public.
What to Do If You’ve Been Exposed
If you’ve been near someone with measles, it’s important to know what to do. First, check if you’re immune by looking at your vaccination records or talking to your doctor. If you’re not, you might need a special shot or treatment.
Watch for symptoms like fever, rash, or cough. If you start to feel sick, stay away from others to stop the virus from spreading.
Knowing how long you’re contagious after exposure is key. Usually, you can spread measles from four days before the rash shows up to four days after. Acting quickly and knowing when you’re contagious helps stop measles from spreading.
Conclusion
Preventing measles is key to keeping us healthy, mainly for young kids. Knowing how measles spreads and taking steps to prevent it can lower the risk. Vaccines are a big help, as they are safe, work well, and are not expensive.
The World Health Organization says getting enough people vaccinated is essential to stop measles outbreaks. They suggest two doses of the measles vaccine to build strong immunity. For more details on measles and how to stop it, check out the World Health Organization’s fact sheet.
By learning about measles and getting vaccinated on time, we can all help lower measles cases. So, can we prevent measles? Yes, by focusing on prevention and vaccination, we can keep our communities safe and stop outbreaks.
