路易斯安那州卫生官员周四报告称，今年迄今该州已有至少5人死于暖沿海水域中发现的食肉型细菌感染。
根据路易斯安那州卫生部的数据，2026年该州已记录至少9例创伤弧菌感染病例，所有9名患者均已住院治疗。
卫生部表示，这9名患者均因伤口接触海水而感染创伤弧菌，且所有人都存在基础健康问题。
卫生部称，过去10年间，路易斯安那州年均报告7例创伤弧菌感染病例，1例死亡病例。但2025年，该州记录的感染病例至少达26例，死亡5例。
佛罗里达州卫生部今年迄今也记录了2例创伤弧菌感染死亡病例。该州2024年报告19例死亡病例，2025年又有5例死亡。该机构表示，在2024年飓风海伦等大型风暴过后，该州感染率有所上升，这些风暴给社区带来了大量洪水和积水。
专家表示，气候变化导致的水温上升也加剧了创伤弧菌感染在新地区出现的风险。
今年春季，纽约长岛沿海地区的水样中检测出了创伤弧菌。
目前已知约有十几种弧菌可引起被称为弧菌病的疾病，但创伤弧菌是其中最严重、最可能致命的一种。根据美国疾病控制与预防中心的数据，每5名感染创伤弧菌的患者中就有1人会因此死亡，感染还可能导致截肢。
美国疾控中心数据显示，弧菌感染最常见的感染时段为5月至10月，此时海水温度最高。
疾控中心表示，人们可能因开放性伤口接触海水，或食用生的或未煮熟的贝类（尤其是牡蛎）而感染弧菌。
路易斯安那州卫生部指出，存在基础健康问题的人群最容易因创伤弧菌感染患上重症，这些基础疾病包括癌症、肝病、艾滋病、地中海贫血以及正在接受免疫抑制治疗的人群。
弧菌伤口感染的症状包括发烧、皮肤变色、伤口流脓或分泌物、伤口周围疼痛肿胀。弧菌血液感染的症状则包括发烧、寒战、 dangerously low blood pressure和皮肤病变。
弧菌感染的胃肠道症状包括腹泻、胃痉挛、恶心和呕吐。
为避免感染，路易斯安那州卫生部建议公众远离盐水或咸淡水混合的半咸水水域。若可能接触过这类水域，要用肥皂清洗伤口。处理海鲜时，要将其彻底煮熟，并将熟食和生食分开存放。
Flesh-eating bacteria has killed 5 in Louisiana this year, officials say

A flesh-eating bacteria found in warm coastal waters is responsible for at least five deaths so far this year in Louisiana, state health officials reported Thursday.
There have been at least nine total cases of Vibrio vulnificus in the state in 2026, according to the Louisiana Department of Health. All nine patients were hospitalized.
The nine patients all contracted Vibrio vulnificus through wounds that were exposed to seawater, the health department said, and all of them had underlying health conditions.
Over the past 10 years, Louisiana has averaged seven cases of Vibrio vulnificus per year and one fatality, the health department said. In 2025, however, there were at least 26 cases and five fatalities recorded in the state.
The Florida Department of Health has also recorded two deaths from Vibrio vulnificus so far this year. In 2024, it reported 19 deaths, and another five in 2025. The agency said Florida saw higher rates of infection after major storms, such as Hurricane Helene in 2024, that brought deluges of floodwater and standing water to communities.
Rising water temperatures caused by climate change are also contributing to the risk of Vibrio vulnificus infections in new regions, experts say.
This spring, Vibrio vulnificus was discovered in water samples taken in coastal areas of New York’s Long Island.
There are about a dozen Vibrio species that can cause the illness known as vibriosis, but Vibrio vulnificus is the most serious and life-threatening. About one in five people who contract Vibrio vulnificus will die from it, per data from the U.S. Centers for Disease Control and Prevention. It can also lead to amputations.
Vibrio infections are most commonly contracted between May and October, when ocean water temperatures are warmest, according to the CDC.
They can be contracted when an open wound is exposed to seawater, or through the consumption of raw or undercooked shellfish, specifically oysters, the CDC said.
Those with preexisting conditions are most susceptible to serious illness from Vibrio vulnificus, the Louisiana Health Department said. Those conditions include cancer, liver disease, HIV, thalassemia and those receiving immune-suppression treatments.
Symptoms of a Vibrio wound infection can include fever, skin discoloration, drainage or discharge, or pain and swelling around the wound. Symptoms of a Vibrio bloodstream infection can include fever, chills, dangerously low blood pressure and skin lesions.
Gastrointestinal symptoms of Vibrio can include diarrhea, stomach cramps, nausea and vomiting.
To avoid infection, the Louisiana Health Department advises the public to stay out of salt or brackish water, which are areas where saltwater and freshwater mix. After a possible exposure, wash wounds with soap. When preparing seafood, cook it thoroughly and keep cooked seafood separate from raw seafood.
