In general, animals tend to avoid humans but they can attack, particularly if they're with their young.
Animal bites can lead to infections that may be serious, sometimes fatal. They can also transmit rabies, an acute viral infection of the nervous system. Rabies occurs in Europe and North America, as well as in the developing world.
In areas of endemic rabies, domestic dogs, cats and other animals shouldn't be petted. Wild animals should be avoided altogether.
If you're bitten by an animal, prompt treatment is vital. Treated early enough, rabies can often be prevented. Once symptoms develop, however, the disease is usually fatal.
If you or a member of your group is bitten by an animal:
Wash the wound immediately using soap, or flush with clean water for at least five minutes. Apply antiseptic, if possible, and cover the area with a dry dressing.
Seek medical attention immediately. If you need a rabies vaccination, the course must be started straight away.
Note the details of the incident and description of the animal. If it's domesticated, try to identify the owner. Find out whether the animal has an up-to-date rabies vaccine. Check if the animal becomes sick within a fortnight.
