Impact of climate change on dermatological conditions related to flooding: update from the International Society of Dermatology Climate Change Committee

Abstract

Climate change contributes to the increase in severity and frequency of flooding, which is the most frequent and deadly disaster worldwide. Flood-related damage can be very severe and include health effects. Among those health impacts, dermatological diseases are one of the most frequently encountered. Both infectious and noninfectious dermatological conditions are increasing after flooding. We searched PubMed using the search term climate change OR global warming OR rainfall OR flooding OR skin. Articles published in the English-language literature were included. We also searched the International Society of Dermatology website library on climate change for additional articles. There is an increased risk of trauma during the course of a natural disaster. The majority of post-tsunami wound infections were polymicrobial, but gram-negative bacteria were the leading causes. Infectious diseases with dermatological manifestations, such as impetigo, leptospirosis, measles, dengue fever, tinea corporis, malaria, and leishmaniasis, are important causes of morbidity among flood-afflicted individuals. Insect bites and stings, and parasite infestations such as scabies and cutaneous larva migrans are also frequently observed. Inflammatory conditions including irritant contact dermatitis are among the leading dermatological conditions. Dermatological conditions such as alopecia areata, vitiligo, psoriasis, and urticaria can be induced or exacerbated by psychological conditions post disaster. Prevention is essential in the management of skin diseases because of flooding. Avoiding exposure to contaminated environments, wearing protective devices, rapid provision of clean water and sanitation facilities, prompt vector controls, and education about disease risk and prevention are important.
