Health
No vaccinations are required for Hong Kong, though travelers planning to stay any length of time should be aware that hepatitis A and B are prevalent across Asia, and precautions are therefore wise.
Tap water is best avoided in Hong Kong. Bottled water is normally provided by hotels and is readily available from convenience stores throughout the territory.
Avoid eating food from street stalls to be on the safe side, as they tend no to have the same standards of hygiene as licensed restaurants.
