Rabies has been circulating in Bali since 2008, in the street dogs and in the macaques around Ubud and Uluwatu — the same monkeys that climb on visitors, take sunglasses and occasionally scratch. Most people never give it a thought until something happens, and that's the problem: the treatment you need after a bite can be difficult to arrange quickly on the island, particularly the immunoglobulin injection given to people who weren't vaccinated beforehand. Being vaccinated before you go doesn't mean ignoring a bite, but it does mean you need less, sooner, and can usually stay on holiday rather than flying home early. Beyond rabies, Bali is straightforward: food and water cover for most people, mosquito sense for dengue, and not much else.
