No, TB (tuberculosis) is not 100% fatal. TB is an infectious disease that is caused by bacteria and can be found in the lungs, but it can also affect other parts of the body. While it is a serious and potentially fatal disease, it is not always 100% fatal.
Treatment is available for TB, and with proper treatment, it is possible to manage the disease and even cure it. Treatment involves antibiotics and other medications, and in some cases, surgery may be needed. With the right treatment, most people can be cured, and the mortality rate of TB is decreasing as treatments become more effective.
However, not everyone is able to access the necessary treatments, and in those cases, TB can be fatal. For example, in countries with limited resources, access to effective treatments may not be available. In addition, people with other serious illnesses, such as HIV/AIDS, may have a harder time fighting TB and may be more likely to die from it.
Overall, TB is not 100% fatal, but it is still a serious and potentially deadly disease. Treatment is available, but not everyone is able to access it, and in those cases, the disease can be fatal. It is important to be aware of the risks and to seek treatment as soon as possible if you think you may have TB.
