We document the absence of carriage of Neisseria meningitidis W-135 of the sequence type 11 in returning pilgrims after the Hajj 2002. This finding contrasts with the 15% carriage rate we previously reported in pilgrims returning from the Hajj 2001. The epidemiology of carriage may be changing or may have been controlled by vaccination and a policy of administering antibiotics to pilgrims from countries with a high incidence of meningococcal disease.
我们记录了2002年朝觐归来的朝圣者中不存在序列型11的脑膜炎奈瑟菌W-135携带情况。这一发现与我们之前报告的2001年朝觐归来朝圣者15%的携带率形成对比。携带情况的流行病学可能正在发生变化,或者可能已通过疫苗接种以及对来自脑膜炎球菌病高发国家的朝圣者施用抗生素的政策得到了控制。
