Take all of the drugs as directed during the entire time.ĭuring the first 2 to 3 weeks, you will be able to pass TB bacteria to others. You will take drugs for four, six or nine months. If you have active TB disease, you'll need to take steps to prevent other people from getting an infection. The body didn't absorb the drugs as expected.They weren't prescribed the right treatment plan.People didn't follow directions for taking the drugs or stopped taking the drugs.

Problems that can lead to such drug-resistant strains of bacteria include the following: If these bacteria are passed on to other people, a new drug-resistant strain can grow over time. When antibiotic drugs aren't used correctly - or drugs fail to kill all the bacteria for another reason - the conditions are ideal for more-resistant versions of the bacteria to get established and multiply. If it does survive, then it can multiply. A random genetic change in a bacterium might give it some quality that makes it more likely to survive the attack of an antibiotic. This happens, in part, because of naturally occurring genetic changes in bacteria. This means that drugs that once cured the disease no longer work. Some forms of the TB bacteria have become drug resistant. Also, a baby may have symptoms from swelling in the fluid around the brain or spinal cord, including:


Active TB disease happens when the immune system can't control an infection. There are no symptoms during latent TB infection.Īctive TB disease. The germs can't do any more harm if the immune system keeps them under control. Immune system cells build a wall around lung tissue with TB germs.

Primary infection is usually followed by the stage called latent TB infection. Some people may get flu-like symptoms, such as: Most people don't have symptoms during a primary infection. But some captured germs may still survive and multiply. The immune system may completely destroy the germs. Immune system cells find and capture the germs. The first stage is called the primary infection. A TB infection may be in one of three stages. When tuberculosis (TB) germs survive and multiply in the lungs, it is called a TB infection.
