UNLABELLED

THE PURPOSE OF STUDY: To assess the epidemiological situation of influenza and influenza like illnesses in Poland in 2010 compared to the situation in 2009.

MATERIALS AND METHODS

We analyzed the data involved in the annual bulletins, among others. "Infectious diseases and poisonings in Poland in 2010" and "Vaccinations in Poland in 2010" issued by the Department of Epidemiology, National Institute of Public Health-National Institute of Hygiene and Chief Sanitary Inspectorate, Department of Prevention and Control of Infections and Infectious Diseases in Humans, reports of incidence of confirmed and suspected cases of influenza, sent to the Department ofEpidemiology, NIPH-NIH by the Provincial Sanitary-Epidemiological Stations.
