Fleet Week New York 2009 was the latest installment of an annual celebration to honor US service personnel. It takes place during Memorial Day and this year's celebration coincided with the peak of novel influenza A (H1N1) virus (S-OIV) activity in New York City. Four service members from the USS Iwo Jima and USS Roosevelt contracted influenza while in New York City and were hospitalized in the Department of Veterans Affairs (VA)-New York Harbor Healthcare System to minimize the risk of widespread outbreak on board the naval vessels. No additional cases were identified on the USS Roosevelt. However, 135 service personnel on the USS Iwo Jima contracted influenza.
Shipwide infection control measures including strict isolation and active case finding were instituted immediately with affected crew members and medical staff receiving oseltamivir. The new case rates remained high for 14 days, but the USS Iwo Jima was able to continue deployment. The secondary infectivity rate was 12.0%. The absolute end of the outbreak correlated with arrival at home port and the ability to move patients off board.
This outbreak not only reinforces the risk for rapid spread of novel strains of influenza A in confined populations but also demonstrates useful strategies to mitigate the severity of an outbreak, including isolation, infection control measures, and off board sick leave when feasible.
2009 年的纽约舰队周是为纪念美国军人而举行的年度庆祝活动的最新一届。该活动在阵亡将士纪念日期间举行，今年的庆祝活动恰逢新型甲型 H1N1 流感病毒（S-OIV）在纽约市活动高峰期。在纽约市期间，来自 USS Iwo Jima 和 USS Roosevelt 的四名军人感染了流感，并被送往退伍军人事务部（VA）-纽约港医疗保健系统住院治疗，以最大限度地减少在海军舰艇上爆发的风险。在 USS Roosevelt 号上未发现其他病例。然而，在 USS Iwo Jima 号上有 135 名军人感染了流感。
立即采取了船舶范围的感染控制措施，包括严格的隔离和主动发现病例，受影响的船员和医务人员接受了奥司他韦治疗。新病例的发病率在 14 天内仍然很高，但 USS Iwo Jima 号仍能够继续部署。继发性感染率为 12.0%。疫情的绝对结束与抵达母港和将患者转移出船有关。
此次疫情不仅突显了新型甲型流感病毒在封闭人群中迅速传播的风险，还展示了减轻疫情严重程度的有用策略，包括隔离、感染控制措施以及在可行的情况下让患者离开船舶休假。
