Bug bites Animal bites Snake bites You're most likely to be bitten by bugs - and the bites or stings of some insects cause unpleasant reactions. Medical attention should be sought if an insect bite causes swelling, bruising, or persistent pain.
Many insects also transmit communicable diseases.
Some insects can sting and transmit disease without the person even being aware of the bite, particularly when camping or staying in basic lodgings. Insect repellents, protective clothing, and mosquito netting are advisable in many parts of the world - they're vital for malaria prevention. Wrist and ankle bands impregnated with DEET are available and provide longer-lasting protection. Many chemists and outdoors shops carry various repellents - shop around. Apply repellent sparingly only to exposed skin or clothing.
