Visiting India: A Comprehensive Travel Health Guide for UK Travellers

India is a vibrant, diverse destination that attracts thousands of British tourists every year. However, the difference in climate, sanitation, and endemic diseases means that preparation is key to a safe journey. At OnlineDoctor24, we recommend starting your health preparations early to ensure you have the necessary immunity and medications before you fly.

According to NHS FitForTravel guidance, the health risks in India can vary significantly depending on whether you are visiting urban centres like Delhi and Mumbai, trekking in the Himalayas, or relaxing in Goa. This guide provides an evidence-based overview of the precautions UK travellers should take.

Routine UK Immunisations

Before considering travel-specific jabs, ensure your routine UK vaccinations are up to date, including DTP (Diphtheria, Tetanus, and Polio) and MMR (Measles, Mumps, and Rubella). Many cases of measles in the UK are imported from international travel.

Recommended Travel Vaccines

• Hepatitis A: Recommended for most travellers as it is transmitted through contaminated food and water.
• Typhoid: Highly recommended due to the risk of exposure in areas with poor sanitation.
• Hepatitis B: Consider this if you are staying long-term, working in healthcare, or may require medical or dental treatment abroad.
• Rabies: India accounts for a high percentage of global rabies cases. While the vaccine does not eliminate the need for treatment after a bite, it simplifies the post-exposure protocol.
• Cholera: Usually only recommended for those at high risk, such as aid workers in areas with active outbreaks.

Malaria risk is present throughout India, including many cities, though the level of risk varies by region and altitude. It is essential to consult a healthcare professional to determine if antimalarial medication (such as Atovaquone/Proguanil or Doxycycline) is required for your specific itinerary.

Preventing Bites

While malaria is a concern, India also has high rates of Dengue Fever and Chikungunya, for which there are no preventative tablets. You must focus on bite avoidance:

• Use an insect repellent containing 50% DEET on exposed skin.
• Wear long-sleeved shirts and long trousers, especially during dusk and dawn when mosquitoes are most active.
• Sleep under a permethrin-treated mosquito net if your accommodation is not air-conditioned or screened.

Travellers' diarrhoea, often colloquially called 'Delhi Belly', is the most common health issue for visitors to the Indian subcontinent. It is typically caused by consuming food or water contaminated with bacteria, viruses, or parasites.

Safe Eating Practices

• Boil it, cook it, peel it, or forget it: Only eat food that has been freshly cooked and is served steaming hot.
• Water: Stick to sealed bottled water or water that has been boiled or chemically treated. Avoid ice in drinks.
• Salads and Fruit: Avoid raw salads and only eat fruit that you have peeled yourself (such as bananas or oranges).
• Hand Hygiene: Wash your hands frequently with soap or use an alcohol-based hand sanitiser before eating.

Heat Exhaustion

Temperatures in India can exceed 40°C during the pre-monsoon months (April to June). British travellers are at risk of heat exhaustion and heatstroke. Ensure you stay hydrated and avoid strenuous activity during the hottest part of the day.

Air Quality

Major Indian cities frequently experience high levels of air pollution, particularly in the winter months. Travellers with underlying respiratory conditions like asthma or COPD should ensure they have sufficient supplies of their preventer and reliever inhalers and may wish to consult a doctor before travelling to highly polluted areas.

Arranging a consultation with an online doctor before your trip is a convenient way to get a personalised travel risk assessment. A GP can review your medical history and itinerary to recommend specific antimalarials or travel vaccinations.

You should speak to a GP if:

• You are unsure which antimalarials are suitable for the region of India you are visiting.
• You need to discuss managing a chronic condition, like diabetes or asthma, while abroad.
• You require a 'fit to fly' letter or documentation for carrying controlled medications through customs.
• You have returned from India and developed a fever, persistent diarrhoea, or a skin rash.

Our online GP service provides advice aligned with NICE Clinical Knowledge Summaries, ensuring you receive the highest standard of evidence-based care before you travel.
