On April 23, 2009, the New York City Department of Health and Mental Hygiene (DOHMH) was notified of a school outbreak of respiratory illness; 2 days later the infection was identified as pandemic (H1N1) 2009. This was the first major outbreak of the illness in the United States. To guide decisions on the public health response, the DOHMH used active hospital-based surveillance and then enhanced passive reporting to collect data on demographics, risk conditions, and clinical severity. This surveillance identified 996 hospitalized patients with confirmed or probable pandemic (H1N1) 2009 virus infection from April 24 to July 7; fifty percent lived in high-poverty neighborhoods. Nearly half were <18 years of age. Surveillance data were critical in guiding the DOHMH response. The DOHMH experience during this outbreak illustrates the need for the capacity to rapidly expand and modify surveillance to adapt to changing conditions.
2009 年 4 月 23 日，纽约市卫生局（DOHMH）接到一起学校呼吸道疾病爆发的通知；两天后，该感染被确定为大流行（H1N1）2009 年。这是美国首例此类疾病的重大爆发。为了指导公共卫生应对决策，DOHMH 利用基于医院的主动监测，然后加强被动报告，收集有关人口统计学、风险条件和临床严重程度的数据。该监测从 4 月 24 日至 7 月 7 日确定了 996 名患有确诊或可能的大流行（H1N1）2009 病毒感染的住院患者；其中 50%居住在高贫困社区。近一半的人年龄在 18 岁以下。监测数据对指导 DOHMH 的应对至关重要。DOHMH 在此次疫情中的经验表明，有必要迅速扩大和修改监测范围，以适应不断变化的情况。
