In recent weeks, there has been a surge in measles cases in our local area, sparking concern among public health experts and the community. Dr. Chris Truitt, one of our experts here at GermBlast, recently shared some insights on this highly contagious virus and provided practical tips for controlling its spread. Let’s break down what the measles virus is, how it impacts individuals, and the best ways to prevent it from spreading further.

What is Measles and Where Does It Come From?

Measles is a viral infection that is part of the paramyxovirus family. It is one of the most contagious airborne viruses, meaning it spreads incredibly easily through respiratory droplets when an infected person coughs or sneezes. Measles typically starts with flu-like symptoms, including fever, runny nose, and coughing, but the defining characteristic of measles is the appearance of a telltale splotchy red rash that usually starts on the face and spreads throughout the body.

The virus primarily affects unvaccinated individuals, particularly children, though anyone who is not immune can be at risk. Due to its highly contagious nature, measles can spread rapidly in places where people are in close contact, such as schools, daycare centers, and healthcare facilities.

Who Does Measles Impact?

While measles can affect anyone, it primarily impacts children, especially those who are unvaccinated. In some cases, measles can lead to serious complications, including pneumonia, encephalitis (brain swelling), and even death. Adults, especially those who are immunocompromised or have weakened immune systems, are also at increased risk for severe illness from measles.

It is essential to recognize that measles not only affects the person infected but also poses a risk to vulnerable populations such as infants, pregnant women, and individuals with chronic health conditions.

How Does Measles Impact Someone?

The symptoms of measles usually begin 10 to 12 days after exposure and can last for several weeks. The initial signs of measles include:

• Fever
• Runny nose
• Coughing
• Conjunctivitis (red, inflamed eyes)
• Sore throat

After a few days, the hallmark rash begins, typically starting on the face and moving down the body. The rash consists of flat, red spots, often with small raised bumps in the center. The rash can last for several days before fading.

In some cases, measles can lead to severe complications such as pneumonia, encephalitis, and ear infections. In rare cases, it can lead to a long-term complication called subacute sclerosing panencephalitis (SSPE), a progressive, fatal brain disorder that can occur years after the initial infection.

How to Mitigate the Spread of Measles

Controlling the spread of measles is crucial, and several preventive measures can be taken:

1. Isolation: If a person exhibits symptoms of measles, it’s vital to isolate them from others to prevent the virus from spreading. Keeping infected individuals away from public spaces, especially schools and healthcare facilities, is key to controlling the outbreak.
2. Use of N95 Masks: Since measles is transmitted through respiratory droplets, wearing a well-fitted N95 mask can help reduce the spread when an infected person coughs or sneezes. N95 masks are designed to filter out tiny airborne particles and provide significant protection in environments where measles may be present.
3. Surface Disinfection: Measles can remain in the air for up to two hours in an enclosed space after an infected person has left. To mitigate the risk, it’s essential to disinfect high-touch surfaces using hospital-grade disinfectants. These surfaces may include door handles, light switches, countertops, and electronic devices. The disinfectant should be allowed to sit for the recommended contact time (usually between 1 to 10 minutes, depending on the product).
4. Air Quality Control: Using high-efficiency particulate air (HEPA) filters in air purifiers can help trap measles virus particles that may be lingering in the air. A high-flow air purifier with a HEPA filter is particularly effective in reducing airborne viruses and improving indoor air quality.
5. Vaccination: The most effective way to prevent measles is through vaccination. The MMR vaccine (measles, mumps, rubella) is highly effective in providing immunity against the measles virus. Ensuring that you and your family members are vaccinated is the best way to protect yourself and your community from measles outbreaks.
6. Hygiene Practices: In addition to vaccination, practicing good hygiene is essential in preventing the spread of measles. Regular handwashing with soap and water, especially after coughing or sneezing, is crucial in reducing the spread of the virus.

Conclusion

Measles is a highly contagious virus that can have serious consequences, but by taking proactive measures, we can limit its spread. Isolating infected individuals, using N95 masks, disinfecting surfaces, and improving air quality can all play a vital role in controlling an outbreak. Most importantly, ensuring that you and your family are vaccinated against measles is the most effective prevention strategy.
