官员表示，这种在温暖海水中滋生的所谓食肉菌今年已在墨西哥湾沿岸造成至少7人死亡。
佛罗里达州2人、路易斯安那州5人因创伤弧菌死亡。这种细菌潜伏在温暖的沿海水域中，可通过开放性伤口或食用生贝类进入人体。美国疾病控制与预防中心表示，全美范围内，感染该细菌的患者中约有五分之一会死亡。
食肉菌幸存者分享亲身经历
去年劳动节周末，萨默林·斯基普沃思在阿拉巴马州奥兰治海滩游玩时，脚部被岸边的岩石划伤。
“当时感觉像是骨折了，”她说。
斯基普沃思表示，没过几天，疼痛加剧，她不得不前往急诊室。
“感觉就像有人把汽油浇在我脚上然后点着了，”她说。
斯基普沃思的创伤弧菌检测结果呈阳性。
“我从来没想过会是感染，”她说。“我只知道脚很疼。”
斯基普沃思不得不接受紧急手术，但术后很快就出院了。医生将她的康复归功于发现及时。
“能活下来我真的很感激，”她说。
远至纽约北部的研究人员都在沿岸水域中检测到了这种细菌。在马里兰州，今年迄今已确认超过20例病例，当地卫生官员警告民众谨慎在切萨皮克湾游泳。
“如今每年，由于气候变化，我们在越来越靠北的纬度地区都能发现这种细菌，”贝勒医学院国家热带医学学院院长彼得·霍特兹博士说道。
哪些人有感染食肉菌的风险？
霍特兹表示，有基础疾病的人群应采取额外防护措施。根据美国疾控中心的数据，这些基础疾病包括肝病、癌症、糖尿病、艾滋病或地中海贫血等血液疾病。部分治疗手段也会增加感染风险，例如免疫抑制疗法和降低胃酸水平的药物。
“如果你存在上述风险因素，且皮肤有开放性伤口或擦伤，就不要在墨西哥湾沿岸和大西洋沿岸的咸淡水中游泳，”霍特兹说。
咸淡水是海水和淡水的混合体，常见于河流入海口区域。
美国疾控中心表示，伤口感染的症状包括发烧、伤口周围皮肤变色或有液体渗出，以及疼痛、红肿或肿胀。其他症状还可能包括寒战、恶心、胃痛和呕吐。
传染病医生卡桑德拉·布莱克博士告诉哥伦比亚广播公司巴尔的摩分社，接触过带菌水体的开放性伤口应立即清洗。

A so-called flesh-eating bacterium that thrives in warm seawater has killed at least seven people this year along the Gulf Coast, officials said.
Two people in Florida and five in Louisiana have died from vibrio vulnificus, which lurks in warm coastal waters and can enter the body through open wounds or from eating raw shellfish. Nationwide, the Centers for Disease Control and Prevention said about 1 in 5 people with the bacteria do die.
Flesh-eating bacteria survivor shares her story
Summerlin Skipworth was spending her Labor Day weekend last year at Alabama’s Orange Beach when she hurt her foot against rocks along the shore.
“It felt like it was broken,” she said.
Within a few days, Skipworth said, the pain spiked, sending her to the emergency room.
“It felt like somebody poured gasoline on my foot and lit it on fire,” she said.
Skipworth tested positive for vibrio vulnificus.
“An infection never crossed my mind,” she said. “I just knew I had pain in my foot.”
Skipworth had to have emergency surgery but was released quickly after the procedure. Doctors credit her recovery to early detection.
“I’m just thankful to be here,” she said.
Researchers as far north as New York have detected the bacteria in waters along the coast. In Maryland, where over two dozen cases have been confirmed so far this year, health officials warned people to be cautious about swimming in Chesapeake Bay.
“With every year now, because of climate change, we’re seeing it higher and higher in more northerly latitudes,” said Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine.
Who is at risk of being infected with flesh-eating bacteria?
Hotez said people with underlying health conditions should take extra precautions to protect themselves. According to the CDC, those conditions include liver disease, cancer, diabetes, HIV or thalassemia, a blood disorder. Some treatments that can also increase the risk of infection include immune-suppressing therapy and medicine to decrease stomach acid levels.
“If you have those risk factors, and if you have an open wound or abrasion in your skin, you do not want to go swimming in brackish waters along the Gulf Coast and the Atlantic Seaboard,” Hotez said.
Brackish water, a mixture of salt water and fresh water, can be found where rivers combine with the ocean.
Symptoms of a wound infection include fever and discoloration or discharge of fluids around the wound as well as pain, redness or swelling, according to the CDC. Symptoms can also include chills, nausea, stomach cramps and vomiting.
Dr. Cassandra Black, an infectious disease doctor, told CBS News Baltimore that open wounds exposed to water with the bacteria should be cleaned immediately.
