Risks linked to infectious diseases in North America (Canada and the US) are low.
In certain areas of Mexico, water and food may carry diseases (cholera, typhoid fever and hepatitis A). You should therefore only drink from sealed bottles and eat peeled or well-cooked food.
Mosquitoes, which carry diseases, are very prevalent in North America, especially in wetland areas. Preventive measures must be taken:
- Wear full-length clothing,
- Use suitable mosquito repellents,
- Sleep under a mosquito net in tropical destinations.
You do not need to worry about malaria prevention, as the disease is not present in this part of the world.
Ticks, which are found in the US and Canada in particular, can spread various infections such as Lyme disease. A careful inspection of the body is recommended after any hiking.
Lastly, be aware that the countryside, which is very vast in all North American countries, is host to a wide range of fauna. We highly recommend you avoid all contact with animals.
