CDC警告前往墨西哥旅遊時謹防致命傷寒

(本報綜述)美國疾病管制與預防中心(CDC)警告前往墨西哥Baja California旅行的民眾,謹防可能接觸致命的洛基山斑疹傷寒。這是一種致命的細菌性疾病,其傳播途徑是透過被感染的褐狗蜱的叮咬而傳播,而這種蜱可能寄生在寵物身上。

一名來自加州聖迭戈的居民,前往墨西哥Baja California旅行後,在當地感染了該疾病,最終在上個月去世。

除了Baja California外,墨西哥的Sonora、Chihuahua、Coahuila 和Nuevo León等多地都發現了洛基山斑疹傷寒的存在。

在上週發布的一項一級旅行警告中,CDC敦促在旅途中或返回美國兩週內出現洛基山斑疹傷寒症狀的旅行者,務必尋求醫療協助。

CDC指出,洛基山斑疹傷寒的症狀包括發燒、頭痛和皮疹,這些症狀可能在症狀出現後的兩到四天內發展。該疾病在感染者中可能迅速發展,如果不及早用抗生素多西環素治療,可能會致命。CDC表示,10歲以下的兒童死於洛基山斑疹傷寒的可能性是成年人的五倍。

加州聖迭戈縣公共衛生官員表示,上一次有人死於洛基山斑疹傷寒還是在2014年。

This 2008 photograph depicts a dorsal view of a female yellow dog tick, Amblyomma aureolatum, which is a vector of Rocky Mountain spotted fever (RMSF) in the country of Brazil.Note that the back of this tick is only partially covered by its hard, scutum, or “shield”, which allows its abdomen to expand to many times the size seen here. Compare this feature with that of the male version of this hard tick, PHIL 11070, of the family Ixodidae, and how the male scutum covers its entire dorsal abdomen.
Rocky Mountain spotted fever (RMSF) is the most severe tick-borne rickettsial illness in the United States. This disease is caused by infection with the bacterial organism Rickettsia rickettsii.
