India is home to millions of Tuberculosis patients. It is one of the deadliest infectious diseases and needs timely attention. Cases of TB are surging at an alarming rate.  Early detection is essential in controlling its spread and improving treatment outcomes. With advancements like molecular testing, it is possible to identify the disease more precisely and detect drug-resistant strains at an early stage. Delayed diagnosis often leads to a higher risk of morbidity and mortality.

Every year, World Tuberculosis Day is observed on March 24 to raise awareness about the disease and its effects on the body. TB is a bacterial infection that happens due to Mycobacterium tuberculosis, taking a toll on the lungs. It is transmitted through the air when an infected person coughs or sneezes. The symptoms commonly seen are persistent cough, fever, night sweats, weight loss, and fatigue. Factors like weak immunity, malnutrition, and close contact with infected individuals increase the risk of TB infection. If left untreated, TB can become severe and cause complications such as lung damage.

Dr Tanish Mandal, consultant pathologist and zonal technical chief, Apollo Diagnostic Delhi said, “Prompt TB detection is lifesaving, as it enables immediate treatment and prevents further transmission. Advanced molecular diagnostics, such as PCR-based tests, have revolutionized TB detection by delivering accurate results within hours, allowing us to save more lives. These tests can identify even low bacterial loads, ensuring early intervention. Early diagnosis also reduces the risk of complications, such as long-term lung damage, empyema, and pneumothorax (lung collapse). Regular screening is essential for controlling the spread of TB. Moreover, timely diagnosis and treatment significantly reduce medical costs, hospital stays, and loss of productivity, thereby easing the financial burden on patients and their families. With the right testing and treatment strategies, we can move closer to eradicating this preventable and treatable disease.”
