A Pill That Stops Measles From Spreading Through the Air? Scientists Say It Works!
Quick Summary
Scientists have created a new pill that stopped a measles-like virus from spreading through the air in animal tests. The pill also helped sick animals recover faster. Researchers say it could one day be a powerful new tool for stopping measles outbreaks.
What Happened?
Measles is a very contagious illness. It spreads through the air when a sick person coughs or sneezes. Right now, there is no approved medicine that directly attacks the measles virus once someone is infected. Doctors mainly rely on vaccines to prevent measles before it starts.
Scientists at Georgia State University wanted to change that. They developed an experimental pill called GHP-88310. The pill works by blocking a key part of the measles virus called the polymerase. Think of the polymerase as the virus’s copy machine. It makes millions of copies of itself to spread through the body. The pill jams that copy machine so the virus cannot multiply.
The researchers tested the pill on ferrets. Ferrets can catch a virus called canine distemper that behaves a lot like measles in humans. When ferrets were given the pill — either shortly before or shortly after being near a sick ferret — the virus could not spread to them. It worked both for viruses passed by direct touch and viruses floating through the air.
The study was published in the scientific journal Nature Microbiology.
Why Does It Matter?
Measles is making a comeback in several parts of the world. More people are skipping their vaccines, which means more outbreaks. A pill like this could be used to protect people during an outbreak, especially those who cannot receive vaccines.
The pill is still in early stages. It has been tested in animals, not people yet. Scientists will need to do more studies before it could be approved for human use. But the results so far are very exciting.
This kind of medicine is called an antiviral. Antivirals are to viruses what antibiotics are to bacteria. Scientists have been working for years to find a good antiviral for measles. This new pill is the most promising one seen in a long time.
Big Words
- Antiviral — a medicine that fights a virus, the same way an antibiotic fights bacteria; antivirals stop viruses from making more copies of themselves
- Polymerase — a special protein inside a virus that acts like a copy machine, making new versions of the virus so it can spread
- Outbreak — when many people in one area get the same illness in a short period of time
- Vaccine — a shot or liquid medicine that teaches your immune system to recognize and fight a specific germ before you ever get sick
- Contagious — easily spread from one person or animal to another
Fun Fact
Measles is so contagious that if one person has it, up to 9 out of 10 people nearby who are not vaccinated or protected will catch it. That makes it one of the most infectious diseases ever known.
Think About It
This pill is a backup tool, not a replacement for vaccines. Why do you think scientists still think vaccines are the most important way to stop measles, even if this new pill works?
