Dr Prashanth Mukka said, “Despite decades of medical advancement, Tuberculosis (TB) continues to be clouded by stigma and misinformation. These myths often delay diagnosis and treatment, making awareness as critical as medication.”
1. It is a disease of the past
Most people think that tuberculosis was an epidemic; however, Dr Prashanth highlighted that TB remains one of the world’s leading infectious killers, with India carrying a significant burden. It is very much a present-day public health challenge.
2. It only affects the lungs
Dr Prashanth states that while pulmonary TB is common, the infection can also impact the brain, spine, lymph nodes, and other organs, known as extrapulmonary TB.
3. TB spreads through touch or sharing food
Dr Mukka clearly states that tuberculosis is infectious in nature and spreads through airborne droplets when an infected person coughs or sneezes, not via handshakes, utensils, or food.
4. Only certain people get TB
According to Dr Mukka, although malnutrition, smoking, and low immunity increase risk, TB can affect anyone exposed to the bacteria.
5. TB is incurable
Most people think that tuberculosis is incurable. However, Dr Mukka mentions that with timely diagnosis and the correct drug regimen, TB is completely curable. The key lies in adherence to treatment.
6. You can stop medicines once you feel better
There is a misconception that stopping medicines once tuberculosis symptoms subside is normal. However, Dr Mukka said, “Symptoms may subside early, but stopping treatment midway can lead to drug-resistant TB; a far more dangerous condition.”
7. TB patients must be socially isolated
Being infectious in nature, tuberculosis patients feel isolated. However, isolation fuels stigma. Once treatment begins, patients quickly become non-infectious and can safely resume normal interactions with precautions.
8. It’s a hereditary disease
Dr Mukka busted one of the biggest myths that tuberculosis is hereditary. He clearly states that TB does not run in families genetically. It spreads through bacteria in the air, not through genes.
9. The BCG vaccine prevents TB for life
The BCG vaccine is considered life-restoring for tuberculosis patients. However, this vaccine offers partial protection, especially in children, but does not guarantee lifelong immunity.
10. TB only affects low-income populations
Dr Mukka explains that tuberculosis is not defined by socio-economic status. Urban lifestyles, stress, and weakened immunity can put anyone at risk.
