Tuberculosis (TB) and Travel: What You Need to Know Before You Go

While many of us think of TB as a thing of the past, it’s still very much present — and remains one of the top 10 causes of death worldwide. If you’re heading to a high-risk country, it’s well worth understanding your risk and knowing how to protect yourself and others.

🦠 What Is Tuberculosis (TB)?

TB is a highly contagious bacterial infection caused by Mycobacterium tuberculosis. It mostly affects the lungs (pulmonary TB), but it can impact other parts of the body like the brain, spine or kidneys.

It spreads through inhalation of respiratory droplets, for example, when an infected person coughs or sneezes.

💡 Did you know? In 2021 alone, 10.6 million people became ill with TB and 1.6 million died globally — making it a major public health concern.

🌍 Where Is TB a Problem?

TB is most common in parts of:

  • Sub-Saharan Africa

  • South-East Asia

  • Eastern Europe

  • South and Central America

Travellers to these regions, especially if staying long-term, working in healthcare, or visiting friends and relatives, may be at higher risk.

The World Health Organization (WHO) considers an annual incidence of 40 per 100,000 or more to be high-risk — and that includes several popular travel destinations.

TB Background

🧑‍⚕️ Who’s At Risk of TB?

While anyone can catch TB, the risk increases if you:

  • Spend extended time in high-incidence areas

  • Have close contact with someone who has TB

  • Are under 5 years old or over 65

  • Have a weakened immune system (e.g. due to HIV, cancer, diabetes, or medications)

Additionally, latent TB — where someone carries the bacteria without symptoms — can reactivate years later, especially if your immune defences weaken.

🧬 What Is Multidrug-Resistant TB (MDR-TB)?

Multidrug-resistant TB is a serious form of TB that doesn’t respond to key first-line antibiotics. It’s harder and more expensive to treat, and only around 40% of people with MDR-TB globally receive proper treatment.

This is a growing concern in global health and highlights why prevention through vaccination and early detection is so important.

🩺 TB Symptoms to Look Out For

Symptoms usually develop slowly, over several weeks or months. They can include:

General TB Symptoms:

  • Fever

  • Night sweats

  • Fatigue

  • Loss of appetite

  • Weight loss

Pulmonary TB (Lung-related) Symptoms:

  • Persistent cough (lasting more than 3 weeks)

  • Coughing up blood or sputum

  • Chest pain

Without treatment, TB can progress gradually and become life-threatening.

💉 TB Vaccination Advice for Travellers

In the UK, the BCG (Bacillus Calmette-Guérin) vaccine is offered to infants and certain high-risk groups — including some travellers.

You may be eligible for the BCG vaccine if:

  • You’re travelling to a country with high TB incidence (over 40 cases per 100,000 population)

  • You plan to stay for 3 months or longer

  • You have close or prolonged exposure to local populations, particularly in healthcare or education

  • You were born or have family connections to high-risk countries

🧒 For children under 1: 0.05 ml intradermal injection
👨 For ages 12 months and over: 0.1 ml intradermal injection
