Tuberculosis (TB) has been known to mankind for centuries, and its traces can be found in ancient civilizations. Even Egyptian mummies have shown signs of this deadly disease. Historians believe Nefertiti and her husband Akhenaten, rulers of ancient Egypt around 1330 BC, may have died from TB. Despite these historical records, the fight against tuberculosis is far from over. It continues to affect millions of people worldwide, and many still suffer in silence due to the stigma surrounding the disease.
Despite significant advancements in medical science and healthcare facilities, myths about TB persist. These misconceptions, often passed down through generations, fuel social isolation, fear, and misunderstanding. Patients dealing with TB not only face physical symptoms but also experience mental and emotional distress due to the stigma attached to the disease. It’s crucial to address these myths, providing facts and insights that can help individuals better understand TB, support those affected, and ultimately reduce the burden of this disease.
In this blog, we will debunk some of the most common myths surrounding TB and replace them with facts that can guide us in the fight against this preventable and treatable disease.
1) Myth: Tuberculosis (TB) Passes Down From One Generation to Another
Fact: TB is not a hereditary disease. Like genetic traits, it does not pass from one generation to another. Tuberculosis is caused by the bacteria Mycobacterium tuberculosis, which is transmitted from person to person through the air when an infected person coughs or sneezes. While certain risk factors such as living conditions, access to healthcare, and immune system strength may influence a person’s susceptibility, TB is not inherited.
2) Myth: Tuberculosis (TB) is Not Curable
Fact: TB is a curable disease. About 95% of people who initiated treatment for TB in India in 2023 began seeing positive results. The treatment for TB involves a combination of antibiotics taken for six months or longer, depending on the type of TB. Success rates for treatment are impressive: in the public sector, the treatment success rate is 86.9%, and in the private sector, it’s 89.5%. The key to successful treatment is early detection, adherence to the prescribed medication regimen, and timely medical supervision.
3) Myth: Tuberculosis (TB) Spreads by Touching or Sharing Food
Fact: TB is primarily spread through the air when an infected person coughs, sneezes, or even talks. Close and prolonged contact with an individual with active TB is the main route of transmission. Sharing food or touching someone with TB will not lead to infection. The bacteria do not spread through casual contact like shaking hands, hugging, or eating together. Awareness of proper hygiene practices and respiratory etiquette is essential in preventing the spread of TB.
4) Myth: Tuberculosis (TB) is Always Fatal
Fact: While TB is a serious disease that can lead to complications if left untreated, it is not always fatal. With timely diagnosis and appropriate treatment, most people recover fully from TB. The success of TB treatment is supported by modern medicines that can cure the disease. However, if TB is not diagnosed early or if treatment is not completed as prescribed, it can lead to severe health consequences, including organ damage or drug-resistant TB, which is harder to treat.
5) Myth: Tuberculosis (TB) Only Affects Poor People – To Treat TB, We Must End Poverty
Fact: While poverty, malnutrition, and poor living conditions can increase the risk of contracting TB, the disease affects people from all walks of life, regardless of their socioeconomic status. TB does not discriminate based on income or social class. It is a global health issue that affects millions of people in both developing and developed countries. The key to reducing TB prevalence lies not only in improving living conditions but also in early detection, better healthcare access, and improved treatment.
6) Myth: Tuberculosis (TB) Only Affects the Lungs
Fact: TB is commonly associated with lung infection, but it can affect other parts of the body as well. When TB bacteria spread through the bloodstream, they can infect other organs, including the kidneys, spine, brain, and even the heart. This is known as extrapulmonary TB. It’s important to understand that TB can manifest in various ways, and prompt diagnosis is necessary to address all forms of the disease.
7) Myth: Tuberculosis (TB) is a Thing of the Past Now
Fact: TB is far from being eradicated. Although progress has been made in controlling TB, it remains a global health challenge. The World Health Organization (WHO) estimates that nearly 10 million people fall ill with TB each year, and around 1.5 million people die from the disease annually. While significant strides have been made in diagnosis, treatment, and prevention, the fight against TB is ongoing. New challenges, such as drug-resistant TB, continue to make the disease more difficult to treat.
8) Myth: Tuberculosis (TB) Cannot Reoccur Once Someone Has Been Infected
Fact: TB can reoccur, especially if the initial infection was not fully treated. In some cases, people may experience a relapse of TB months or even years after completing treatment. This can happen if the person does not complete their full course of antibiotics, leading to the development of drug-resistant strains. Regular follow-up care and adherence to treatment protocols are critical to preventing reactivation of the disease.
9) Myth: Once Vaccinated in Childhood, One Cannot Be Infected Again
Fact: The BCG vaccine is widely administered in childhood in many countries to provide some protection against severe forms of TB, particularly in children. However, this vaccine does not guarantee lifelong immunity, and individuals can still contract TB later in life if exposed to the bacteria. It is important to note that the BCG vaccine primarily protects against severe forms of TB, such as TB meningitis, rather than preventing infection altogether. Individuals still need to follow appropriate preventive measures throughout their lives.
10) Myth: Patients can safely discontinue their anti-TB medications once their symptoms improve.
Fact: One of the most dangerous myths surrounding TB is that patients can stop their treatment as soon as they begin to feel better. TB treatment requires a strict regimen of antibiotics that must be taken for the entire prescribed duration, usually six months. Stopping treatment prematurely can lead to a relapse, drug resistance, and the development of multidrug-resistant TB (MDR-TB), which is much harder to treat. Adherence to the full course of treatment is critical to ensuring the successful cure of TB.
11) Myth: Everyone with Tuberculosis (TB) is Infectious
Fact: Not everyone with TB is infectious. People with latent TB infection (LTBI) carry the bacteria in their bodies but do not exhibit symptoms and cannot spread the bacteria to others. Only individuals with active TB, particularly those with pulmonary TB (which affects the lungs), are contagious. Even among people with active TB, the risk of transmission can be significantly reduced once they start treatment and have been on the medication for a few weeks.
Breaking the Myths: A Unified Effort Towards a TB-Free World
Tuberculosis is a serious disease, but it is also preventable, treatable, and curable. The myths surrounding TB create unnecessary barriers that prevent people from seeking early diagnosis and treatment. By debunking these misconceptions, we can reduce the stigma surrounding the disease, encourage people to seek medical help and promote treatment adherence.
Public awareness and education are key to controlling TB. The World Health Organization’s (WHO) End TB Strategy, which aims to reduce TB deaths by 90%, reduce TB incidence by 80%, and eliminate catastrophic costs for TB-affected households by 2030, offers a roadmap to ending the global TB epidemic. India’s National TB Elimination Programme (NTEP) further reflects this vision, with the ambitious goal of achieving a TB-free India by 2025.
It’s time for us to come together, educate ourselves and others, challenge misconceptions, and support those affected by TB. By doing so, we can make significant progress towards ending the TB epidemic and saving lives. Let’s not allow myths to stand in the way of progress. The fight against TB is a collective effort, and together, we can build a TB-free world.
