Skin

Abstract Skin problems are common on expeditions. Many travellers seek to tan, but appropriate skin protection is essential. Wounds require assessment and treatment that includes careful cleaning and closure. Bites from insects, animals or humans are especially prone to infection. Blisters and splinters are common hazards, while crush injuries are painful and, if extensive, can cause systemic complications. Anything penetrating the skin can result in infection and an abscess. Burns are very painful and, if extensive, require appropriate fluid resuscitation. Ectoparasitic infestations such as those from fleas and lice can easily be acquired from local accommodation, while ticks are common in the environment and can spread many different types of disease from vertebrate vectors. Invasive maggots and flies are particularly unpleasant. Tropical ulcers and marine wound infections can heal slowly; occasionally the infections can be very serious. Minor fungal skin infections are very common, particularly in hot environments, and, if not appropriately treated, can cause considerable discomfort.
