A Vibrio cholerae O1 outbreak emerged in Haiti in October 2022 after years of cholera absence. In samples from a 2021 serosurvey, we found lower circulating antibodies against V. cholerae lipopolysaccharide in children <5 years of age and no vibriocidal antibodies, suggesting high susceptibility to cholera, especially among young children.
2022 年 10 月,海地出现了霍乱弧菌 O1 疫情,此前多年未出现霍乱。在 2021 年血清学调查的样本中,我们发现 5 岁以下儿童体内针对霍乱弧菌脂多糖的循环抗体较低,且不存在杀弧菌抗体,这表明他们极易感染霍乱,尤其是幼儿。
