Abstract
The first laboratory-confirmed case of 2009 pandemic influenza A (H1N1) in Greece was reported on May 18, 2009. During July--August, Greece experienced a moderate wave of transmission of 2009 H1N1; a stronger wave began in October, and a peak in incidence occurred during November 23-29. To conduct surveillance in Greece for 2009 H1N1, the Hellenic Centre for Diseases Control and Prevention (HCDCP), in collaboration with the National Health Operations Centre (NaHOC) of the Ministry of Health and Social Solidarity, collected and analyzed data regarding 1) laboratory-confirmed 2009 H1N1 cases, 2) influenza-like illness (ILI) visits to hospital emergency departments (EDs), 3) ILI hospitalizations, 4) confirmed 2009 H1N1 admissions to intensive-care units (ICUs), and 5) confirmed 2009 H1N1 deaths in hospitals. This report summarizes the findings in Greece during May 18, 2009-February 28, 2010, when 18,075 laboratory-confirmed 2009 H1N1 cases, 294 ICU admissions, and 140 deaths were reported. The majority of severe 2009 H1N1 cases were associated with underlying medical conditions (68.4% of ICU admissions and 82.1% of deaths), including pregnancy. In Greece, where 2009 H1N1 vaccination coverage was limited and a large proportion of the population likely remains susceptible, continued surveillance and effective vaccination programs will be needed this winter to combat 2009 H1N1 and any other circulating influenza virus.
