Multiplier and can cause Infections Dangerous In humans, the journal reports The insiderCiting the research work of scientists from Florida Atlantic University (FAU) released in early 2023 Journal of Scientific Reports. These are called bacteria Vibriovulnificus, Lie in hot water (above 20°C)and critical development A mass of brown algae That blooms‘Atlantic Ocean And Especially washing up on beaches of Florida (Southeastern United States), such as the popular Miami Beach and Key Biscayne.

In this case, blisters appear on the skin at the level of infected wounds. Healthy people usually develop A mild illness. But in In rare cases, In immunocompromised people, for example (those with chronic liver disease), the infection progresses rapidly Sepsis And may die in a few days. These bacteria areThe leading cause of human mortality in the marine environmentsays Tracy Mainzer, assistant professor of biology at Florida Atlantic University. However, rest assured, Vibrio infections are rare : Florida Register 34 cases and 10 deaths in 2021 And 74 cases and 17 deaths in 2022 (Abnormal increase due to impacts of Cyclone Ian), acc Florida Department of Health who warned that there is There is no evidence of human-to-human transmission of Vibrio vulnificus. Despite that Vibrio Vulnificus mainly threatens the United States, European and therefore French Atlantic coasts are concerned. However, to a lesser extent: 32 cases of non-cholera Vibrio infections (including Vibiro vulnificus infection) identified between 2001 and 2003 according to Public Health France (latest statistics published on the subject). to To avoid infection, The researchers published Several recommendations for when you’re at the beach:
