ABSTRACTBackground and Methods: 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.Results: 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.Conclusions: 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.

The Impact

SUMMARYA pandemic influenza A(H1N1) 2009 outbreak in a summer school affected 117/276 (42%) students. Residential social contact was associated with risk of infection, and there was no evidence for transmission associated with the classroom setting. Although the summer school had new admissions each week, which provided susceptible students the outbreak was controlled using routine infection control measures (isolation of cases, basic hygiene measures and avoidance of particularly high-risk social events) and prompt treatment of cases. This was in the absence of chemoprophylaxis or vaccination and without altering the basic educational activities of the school. Modelling of the outbreak allowed estimation of the impact of interventions on transmission. These models and follow-up surveillance supported the effectiveness of routine infection control measures to stop the spread of influenza even in this high-risk setting for transmission.

Background and Objective.Assessing the impact of 2009 influenza A (H1N1) on healthcare workers (HCWs) is important for pandemic planning.Methods.We retrospectively analyzed employee health records of HCWs at a tertiary care center in New York City with influenza-like illnesses (ILI) and confirmed influenza from March 31, 2009, to February 28, 2010. We evaluated HCWs' clinical presentations during the first and second wave of the pandemic, staff absenteeism, exposures among HCWs, and association between high-risk occupational exposures to respiratory secretions and infection.Results.During the pandemic, 40% (141/352) of HCWs with ILI tested positive for influenza, representing a 1% attack rate among our 13,066 employees. HCWs with influenza were more likely to have fever, cough, and tachycardia. When compared with the second wave, cases in the first wave were sicker and at higher risk of exposure to patients' respiratory secretions (P = .049). HCWs with ILI- with and without confirmed influenza-missed on average 4.7 and 2.7 work days, respectively (P = .001). Among HCWs asked about working while ill, 65% (153/235) reported they did so (mean, 2 days).Conclusions.HCWs in the first wave had more severe ILI than those in the second wave and were more likely to be exposed to patients' respiratory secretions. HCWs with ILI often worked while ill. Timely strategies to educate and support HCWs were critical to managing this population during the pandemic.
