Tuberculosis is a bad disease that affects around 11 million people every year and causes a lot of deaths worldwide. Scientists have been studying the bacteria that cause tuberculosis for a time. Now new research says that another common illness, the flu, may be making tuberculosis worse.
A new study by researchers at Imperial College London found that the flu can weaken our body’s ability to fight the bacteria that cause tuberculosis. This is the time that scientists have found proof that catching the flu may increase our risk of getting tuberculosis.
This discovery is very important for health especially in countries where tuberculosis is still a big problem. Researchers think that getting a flu shot every year may help prevent tuberculosis.
Human Challenge Study
To study the relationship between the flu and tuberculosis scientists used blood samples from people who were part of a study program at Imperial College London. In this program healthy people are given the flu virus on purpose so that scientists can study how the virus affects them.
By using these blood samples scientists can see how the flu virus affects our system. They took blood samples from people before. After they got the flu. Then they exposed these blood samples to the bacteria that cause tuberculosis in a laboratory.
The results showed that the flu makes it easier for tuberculosis bacteria to grow. This means that our body’s natural defenses are not as strong when we have the flu.
Immune System Impact
The study found that the flu disrupts our systems ability to fight tuberculosis. The flu virus interferes with a part of our immune system that helps keep tuberculosis under control.
When this part of our system is not working properly our body is not as good at fighting tuberculosis bacteria. Scientists think that this may be why people who get the flu are more likely to get tuberculosis or have it get worse if they already have it.
Vaccine Potential
One of the exciting things about this study is that it suggests that flu shots may help prevent tuberculosis. In countries where tuberculosis is still a big problem getting a flu shot may help prevent people from getting tuberculosis. This is especially important because tuberculosis is still a problem in many parts of the world. There are forms of tuberculosis that are resistant to medicine, which makes them very hard to treat.
By getting a flu shot we may be able to protect our system and reduce our risk of getting tuberculosis. This could be a cost-effective way to prevent tuberculosis especially in areas where it is still a big problem.
Future Steps
While this study is very promising scientists need to do research before they can say for sure that flu shots can help prevent tuberculosis. They need to do studies to see if flu shots really can reduce the risk of tuberculosis.
This study is a very important step forward. It shows that scientists need to think about how other illnesses, like the flu can affect our body’s ability to fight tuberculosis. This could help us find ways to prevent tuberculosis and make the world a healthier place.
Tuberculosis is still a big problem worldwide. This study gives us hope that we may be able to use something that already exists like the flu shot to help prevent it. If future studies confirm these findings flu shots may become a tool in the fight against tuberculosis.
