Honest about the risks, and specific about what prevents each one.
Air pollution
The Government of Canada describes urban air pollution in India as at times extremely hazardous, particularly in winter. It is the risk most likely to affect a traveller with asthma, COPD or heart disease, and the one least likely to be on a vaccine list.
Prevention Extra reliever inhaler in hand luggage, a well-fitted N95, and check the daily air quality index the way you would check the weather. Move outdoor plans to the morning.
Traveller’s diarrhoea
The most likely thing to interrupt the trip. Contaminated food, water and ice are the usual routes, and it is no respecter of hotel stars.
Prevention Bottled or boiled water including for teeth, ice only where you trust the kitchen, food cooked fresh and hot. We can send you with rehydration salts and, where appropriate, a standby antibiotic.
Traffic
Road crashes are among the risks CDC names for travellers here. Traffic is dense, fast and improvisational, and pedestrians are not the priority.
Prevention Use app-based cars rather than driving yourself. Avoid night journeys on rural highways. If you get on a motorbike, wear a real helmet and check your insurance covers it.
Dengue
A risk to travellers, spread by daytime-biting mosquitoes, so evening-only precautions miss it. The Government of Canada notes there is no vaccine or medication available in Canada to prevent it.
Prevention Repellent through the day. Air-conditioned or screened rooms.
Rabies
Present in dogs and wildlife. Street dogs are everywhere and the temple macaques are bolder than they look — a snatched bag can become a scratch.
Prevention Do not feed or handle animals. Any bite, scratch or lick on broken skin: wash for a full fifteen minutes and seek medical advice the same day, vaccinated or not.
Zika
A risk in India. Spread mainly by mosquito bite but also sexually, and it can cause serious birth defects.
Prevention If you are pregnant or planning a pregnancy, this deserves a proper conversation before you book rather than after.
Altitude
The Government of Canada warns that high-altitude illness can be fatal and asks trekkers above 3,000 metres to know the symptoms. Ladakh, Sikkim and the Himalayan treks all qualify, and Leh is reached by air — you arrive at altitude rather than climbing to it.
Prevention Plan rest days into the itinerary. Acetazolamide is prescribable and we can sort it at the same appointment.
Heat
CDC names heat illness among the risks. The pre-monsoon months in the north are genuinely dangerous, not merely uncomfortable.
Prevention Plan sightseeing for early morning, drink more than you feel like, and treat air conditioning as a health measure rather than a luxury.
