Overexposure to sunlight during long stays in tropical countries can reveal short- and long-term harmful effects on the skin of Caucasian residents, especially for fair-skinned subjects. The aim of this study was to describe sun exposure and sun protection behaviors during lifetime among French adults who declared having experienced at least one expatriation period in tropical or high-sun index areas for a duration of more than three consecutive months. ⋯ Although expatriates are aware of travel health advices concerning the countries where they planned to stay, they are usually poorly informed about sun exposure risk factors. Such individuals who planned to expatriate in countries with a high ultraviolet index should benefit from a visit to a travel clinic including specific health care information for risk related to sun exposure, ie, skin cancers and photoaging.

Whether the result of cyclical atmospheric changes, anthropogenic activities, or combinations of both, authorities now agree that the earth is warming from a variety of climatic effects, including the cascading effects of greenhouse gas emissions to support human activities. To date, most reports of the public health outcomes of global warming have been anecdotal and retrospective in design and have focused on heat stroke deaths following heat waves, drowning deaths in floods and tsunamis, and mosquito-borne infectious disease outbreaks following tropical storms and cyclones. ⋯ Nevertheless, temporal relationships between environmental factors and human health outcomes have been identified and may be used as criteria to judge the causality of associations between the human health outcomes of climate changes and climate-driven natural disasters. Travel medicine physicians are obligated to educate their patients about the known public health outcomes of climate changes, about the disease and injury risk factors their patients may face from climate-spawned natural disasters, and about the best preventive measures to reduce infectious diseases and injuries following natural disasters throughout the world.

Severe acute respiratory syndrome-associated coronavirus (SARS-CoV) was introduced to the United States through air travel. Although the risk of SARS-CoV transmission within aircraft cabins has been addressed by several studies, the magnitude of the risk remains unclear. ⋯ Transmission of SARS-associated CoV was not observed, suggesting that the risk of transmission is not amplified aboard aircraft.
