What does "Latent TB" mean?
Table of Contents
Latent tuberculosis (TB) is a condition where a person has the TB bacteria in their body, but they do not have any symptoms and are not contagious. The immune system keeps the bacteria in check, so the person feels healthy and can live a normal life. However, there is a risk that the bacteria can become active later, especially if the person's immune system weakens.
How Does TB Spread?
TB usually spreads through the air when a person with active TB coughs or sneezes. If someone breathes in the droplets, they can become infected. However, for latent TB, the bacteria stay inactive, meaning it does not spread to others.
Who is at Risk?
Certain groups of people are at higher risk of having latent TB. This includes individuals living with HIV, those who have been in close contact with someone who has active TB, and people with weakened immune systems.
Why is Testing Important?
Testing for latent TB is important because it can help in identifying people who may develop active TB in the future. Early treatment can help prevent this from happening. Common testing methods include blood tests and skin tests.
Treatment for Latent TB
If someone is diagnosed with latent TB, they may be given preventive therapy. This treatment helps to kill the inactive bacteria and reduce the risk of developing active TB later on. Medications are usually taken for several months.
Conclusion
Latent TB is a serious health issue, especially for vulnerable populations. Regular testing and treatment can help control and reduce the risk of active TB, contributing to better health outcomes for affected individuals.
