During October 2000-May 2001, influenza A (H1N1), A (H3N2), and B viruses were identified in the Northern Hemisphere. Influenza A (H1N1) and B viruses circulated widely; influenza A (H3N2) viruses were reported infrequently and were not associated with widespread outbreaks in any country during October 2000-May 2001. Since May 2001, influenza A (H1N1) and B viruses have predominated in Asia and Oceania; influenza A (H3N2) and B viruses have predominated in Africa and South America. This report summarizes influenza activity in the United States* (1) and worldwide during May-September 25; influenza A (H1N1), A (H3N2), and B viruses continued to circulate worldwide and were associated with mild to moderate levels of activity. This activity underscores the need to follow the recommendations of the Advisory Committee on Immunization Practices (ACIP) (2,3) for the timely vaccination of persons at high risk for influenza-related complications.
在2000年10月至2001年5月期间,北半球发现了甲型(H1N1)、甲型(H3N2)和乙型流感病毒。甲型(H1N1)和乙型流感病毒广泛传播;甲型(H3N2)病毒报告较少,且在2000年10月至2001年5月期间,未在任何国家引发大规模疫情。自2001年5月以来,甲型(H1N1)和乙型流感病毒在亚洲和大洋洲占主导地位;甲型(H3N2)和乙型流感病毒在非洲和南美洲占主导地位。本报告总结了美国*(1)以及全球5月至9月25日期间的流感活动情况;甲型(H1N1)、甲型(H3N2)和乙型流感病毒继续在全球传播,并引发了轻度至中度的流感活动。这一情况凸显了遵循免疫实践咨询委员会(ACIP)(2,3)的建议,及时为流感相关并发症高危人群接种疫苗的必要性。
