During the COVID-19 pandemic, we saw countless times how some people remained completely unaffected by the virus while others were suffering a great deal. Similarly, millions of people live with ‘Inactive Tuberculosis’ and do not know about it until it becomes active. Tuberculosis, or TB, is a serious sickness caused by tiny germs called Mycobacterium tuberculosis. UCLA Health explains that these germs can attack your lungs, making it hard to breathe. But they can also travel through your blood to other parts of your body. Inactive, or latent TB is a bit different- the variables of the virus may be in your system, but you will not get sick. According to the Center of Disease Control and Prevention (CDC) there is no cough, no fever, or no fatigue. Although Tuberculosis is a communicable disease, inactive TB cannot be spread through contact. While diagnosing, a simple blood draw or a skin test, will show that the disease is present, but your chest X-ray might be completely fine. Even though its not serious it's important to treat latent TB. Why Should You Get Inactive TB Treated? TB is a serious illness that can make you very sick, causing bad cough, tiredness, fever, and weight loss. Treating latent TB is like stopping the virus, while it's still small and easy to treat. It's much easier to kill the dormant germs than to fighting the active disease. By simply taking medicine for latent TB, you can protect yourself from a serious condition. The virus can also travel through your blood to other parts of your body meaning it can affect your spine, the little glands that fight infection (lymph nodes), your kidneys, and even your brain. It's important to know that TB can make anyone sick, no matter how old they are. Can You Diagnose And Treat An Inactive TB? The CDC explains there are two main ways to test for TB- a blood test and a skin test. The blood test is like checking a sample of your blood to see if it reacts to TB germs. The skin test involves putting a tiny bit of test material under your skin and seeing if you have a reaction after a few days. If you have latent TB, you'll need to take medicine for several months. This medicine is like a special cleaner that kills sleeping germs. If you stop taking the medicine too early, the germs might not be completely gone. And they can become resistant to the medication. Because there are fewer ‘germs’ to kill with latent TB, the treatment is much shorter and easier than treatment for active TB. Following a medication schedule is the best way to make sure you stay healthy and don't develop active TB. How Can One Carry A Disease And Not Know? A 2017 study published in the Viruses Journal explained that we all have slightly different versions of our genes (polymorphisms) and these differences can affect how our bodies react to any virus. Some gene variations might make your immune system stronger against a specific virus, while others might make you more vulnerable.
