Tuberculosis, or TB, might seem like a disease of the past, but it remains a persistent and serious global health threat. In fact, TB has recently overtaken COVID-19 as the world’s deadliest infectious disease, claiming more than a million lives each year. Despite significant advances in medical science, this respiratory infection continues to impact millions, especially in low and middle-income countries.

The good news? TB is both preventable and treatable. By understanding the best strategies for prevention and the available treatment options, we can take effective steps to control its spread and protect ourselves and our communities. In this blog, we’ll dive into practical ways to prevent TB, outline the treatment process, and explore the latest efforts to curb this disease.

Tuberculosis – Basics and risks

Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs but can spread to other parts of the body, including the kidneys, spine, and brain. Despite being a preventable and treatable disease, TB remains one of the world’s top infectious killers. Its persistence is partly due to how easily it spreads through the air when a person with active TB coughs, sneezes, or even speaks, releasing bacteria into the air for others to inhale.

Types of TB: Latent and Active 

TB exists in two forms: latent and active. Latent TB occurs when the bacteria are present in the body but inactive, meaning the person shows no symptoms and cannot transmit the disease, however, latent TB can become active if the immune system weakens. Active TB is contagious and causes noticeable symptoms, including a persistent cough, fever, night sweats, and weight loss.

Symptoms to look out for: 

The symptoms of TB vary depending on where it affects the body. When it impacts the lungs—known as pulmonary TB—the symptoms typically include:

• A persistent cough lasting three weeks or more
• Coughing up blood or sputum
• Chest pain, especially during breathing or coughing
• Fever and night sweats
• Loss of appetite and unintended weight loss

If TB spreads beyond the lungs, it can cause symptoms related to the affected area, such as back pain if it reaches the spine or blood in the urine if it affects the kidneys.

High-risk groups for TB:

While TB can affect anyone, certain groups are at a higher risk. People with weakened immune systems, such as those with HIV/AIDS or diabetes, are particularly vulnerable, as their bodies struggle to contain the bacteria. Healthcare workers, who may be frequently exposed to infected individuals, and those living or working in crowded environments, such as prisons or shelters, are also at greater risk.

Preventing tuberculosis – Essential strategies

Preventing tuberculosis requires a combination of personal hygiene, community awareness, and medical interventions, especially in areas where TB is prevalent. From vaccination to lifestyle habits, these strategies offer effective ways to reduce the risk of contracting TB.

1. BCG vaccination for high-risk groups

The Bacillus Calmette-Guérin (BCG) vaccine is widely used in countries with high TB rates, particularly for young children, as it offers substantial protection against severe forms of TB, like TB meningitis. While BCG does not completely prevent TB infection, it significantly lowers the risk of developing severe TB in infants and young children, making it a key preventive measure in high-risk areas.

2. Boosting indoor air quality and ventilation

Good ventilation is essential to reducing the spread of airborne diseases like TB. In places where TB is more common, ensuring that homes and shared spaces have adequate airflow can help disperse bacteria released into the air. Opening windows, using exhaust fans, and installing air purifiers with HEPA filters can make indoor environments safer, particularly in crowded or poorly ventilated areas.

3. Wearing protective masks in high-risk settings

Wearing a mask, particularly in enclosed or crowded settings, can offer an added layer of protection. For those in high-exposure areas or those with active TB, wearing a mask helps contain bacteria, while high-efficiency masks like P2 or N95 masks are ideal for filtering airborne particles, including those associated with TB. 

The AMD P2 mask, for instance, is equipped with nano-fibre technology, filtering out more than ≥99.66% of airborne particles, and has ≥99.92% Bacterial Filtration Effiecy (BFE), providing protection on par with the N95 standard.

4. Practising good cough hygiene

For individuals with active TB or suspected TB, practising cough hygiene is crucial. This includes covering the mouth with a tissue or elbow when coughing or sneezing, promptly disposing of tissues, and washing hands regularly. Such habits help limit the spread of TB bacteria to others and contribute to better hygiene overall.

5. Testing and monitoring in high-risk groups

Regular TB testing for individuals in high-risk groups is essential to catching the disease in its early stages. This includes people who work in healthcare, individuals with compromised immune systems, and those who have close contact with TB patients. Testing can identify latent TB, allowing for preventive treatment before it becomes active and contagious.

6. Early detection through screening and awareness campaigns

Countries with high TB rates often implement regular screening and awareness campaigns to identify cases early and educate communities about TB prevention. By understanding the symptoms and knowing when to seek medical attention, individuals can help reduce the spread of TB.

7. Promoting a healthy immune system

A strong immune system is a natural defence against TB. Proper nutrition, regular exercise, adequate sleep, and stress management can help keep the immune system robust, allowing the body to combat infections more effectively. For those at higher risk, these lifestyle habits are especially important to prevent the progression from latent to active TB.

Treatment options for tuberculosis

Effective treatment for tuberculosis (TB) is vital to prevent the disease from progressing, spreading, and potentially developing drug resistance. TB treatment usually involves a combination of antibiotics over an extended period, ensuring that every last bacterium is eradicated from the body. Here’s a breakdown of the treatment options and what to expect.

1. Standard treatment regimen 

The primary treatment for TB, especially in its drug-sensitive form, is a combination of antibiotics taken over six to nine months. This regimen typically includes:

• Isoniazid
• Rifampicin
• Ethambutol
• Pyrazinamide

In the initial phase, patients are often prescribed all four drugs for two months to reduce the bacterial load rapidly. After this, two drugs (usually isoniazid and rifampicin) are continued in the maintenance phase for an additional four to seven months. Completing the entire course is essential, as stopping early can lead to a resurgence of the infection and potentially to drug-resistant TB.

2. Directly Observed Treatment (DOT)

Directly Observed Treatment (DOT) is a system in which healthcare providers or trained volunteers directly observe patients as they take their TB medication. DOT is especially important for communities where adherence is challenging, as it ensures that patients complete the full course. By confirming that every dose is taken, DOT helps prevent the development of drug-resistant TB strains and reduces the chances of treatment failure.

3. Treatment for Drug-Resistant TB

Drug-resistant TB (DR-TB) arises when standard antibiotics are no longer effective against the bacteria. Multidrug-resistant TB (MDR-TB), which is resistant to both isoniazid and rifampicin, is particularly challenging to treat and requires a different approach. Patients with DR-TB undergo a longer treatment regimen, often lasting 18–24 months and involving second-line antibiotics like:

• Levofloxacin or Moxifloxacin
• Bedaquiline
• Linezolid

These drugs come with a higher risk of side effects, and careful monitoring is essential. Treatment for DR-TB is rigorous and requires close supervision to manage potential side effects and ensure patient safety.

4. Latent TB treatment

For individuals with latent TB infection, the goal is to prevent the bacteria from becoming active. While people with latent TB don’t have symptoms, they are at risk of developing active TB if their immune system weakens. Treatment for latent TB usually involves a single antibiotic, either isoniazid or rifapentine, taken for several months. This approach significantly reduces the risk of latent TB progressing to active TB, making it an effective preventive measure.

5. Supportive care and nutritional support

Supporting the immune system is crucial in TB recovery. Patients are encouraged to follow a balanced diet rich in vitamins and minerals, with an emphasis on nutrients that bolster immunity, like vitamin C, vitamin D, and zinc. Nutritional support may be particularly beneficial for individuals in low-resource settings where malnutrition is prevalent. Additionally, managing stress and prioritising rest play a role in the recovery process, as a well-supported immune system can aid in the body’s response to treatment.

Importance of completing TB treatment 

One of the biggest challenges in TB treatment is patient adherence to the full course of antibiotics, especially given the extended duration. Skipping doses or stopping treatment early can lead to a relapse, where the infection returns in a more severe and potentially drug-resistant form.

Lifestyle tips to reduce TB risk

1. Strengthen your immune system

A robust immune system is your first line of defence against TB. To keep your immunity in top form:

• Eat a balanced diet: Incorporate fruits, vegetables, lean proteins, and whole grains, focusing on nutrient-dense foods rich in vitamins C, D, and zinc to support immune function.

• Stay physically active: Regular exercise, like walking or cycling, can enhance immune health, strengthen the respiratory system, and improve lung function.

• Get adequate rest: Proper sleep helps your body repair and recharge, making it better equipped to fight off infections.

2. Limit alcohol consumption and quit smoking

Both smoking and excessive alcohol intake can weaken the lungs and immune system, making it easier for TB bacteria to take hold. To protect yourself:

• Limit alcohol: Excessive drinking impairs immune function and can reduce the body’s ability to fight infections.

• Quit smoking: Smoking damages lung tissue and makes you more vulnerable to respiratory infections, including TB. Quitting smoking not only reduces TB risk but also improves overall lung health.

3. Maintain a clean living environment

Since TB can persist in poorly ventilated and unsanitary conditions, maintaining a clean and hygienic environment is essential for reducing its spread. Regularly cleaning and disinfecting surfaces, especially in shared spaces, helps minimise bacteria build-up and improves overall air quality.

Conclusion: Recognise the signs when to seek help

1. Persistent symptoms

If you experience a prolonged cough that lasts more than three weeks, ongoing chest pain, or persistent fatigue, it’s essential to consult a healthcare provider. These symptoms could indicate active TB or another underlying respiratory condition requiring medical evaluation.

2. Fever, night sweats, and unintended weight loss

Recurring fevers, excessive night sweats, and unexplained weight loss are common symptoms of TB. If you experience any of these, especially in combination, they warrant immediate attention to rule out TB and initiate treatment if necessary.

3. Exposure to high-risk environments or individuals

If you’ve recently been in close contact with someone diagnosed with active TB or spent time in high-risk areas, seek medical guidance even if you’re asymptomatic. Early testing and preventive treatment may be recommended.

4. Immunocompromised individuals

Those with weakened immune systems—due to conditions like HIV, diabetes, or prolonged use of immunosuppressive medications—should remain vigilant. TB poses a higher risk to individuals with compromised immunity, making regular screenings and preventive care critical.

5. Development of severe symptoms

In cases of severe respiratory distress, blood in your sputum, or difficulty breathing, seek emergency medical attention. These symptoms could signify advanced TB or complications that require urgent care.

Creating an action plan

If you are diagnosed with TB, work with your healthcare provider to establish a tailored action plan, including medication schedules, follow-up visits, and lifestyle adjustments to manage the condition effectively.
