A serological surveillance programme for avian influenza A virus (AIV) subtype H5 and H7 in poultry was implemented in Poland in 2008-2013 with two main objectives: i) to detect subclinical infections or previous exposures to AIV H5 and H7 subtypes and ii) to demonstrate the AI- free status of Poland. During this period, over 45 000 serum samples from 2833 holdings were examined using the hemagglutination inhibition test (HI). The presence of HI antibodies was detected in 8 breeder geese holdings (7 positive for H5 and 1 positive for H7 AIV) and in 1 breeder duck holding (H5-positive), which represented 0.32% of all investigated holdings. All seropositive flocks were examined by real time RT-PCR with negative results, which substantiated the AI-free status of Poland. Positive results detected in clinically healthy poultry kept in an open range system indicate prior infections with low pathogenic AIV originating from the wild-bird reservoir.

The aim of this study was to conduct an epidemiological and laboratory surveillance of Influenza-Like Illnesses (ILI) in Polish Armed Forces, civilian military personnel and their families in 2011/2012 epidemic season, under the United States Department of Defense-Global Emerging Infections Surveillance and Response System (DoD-GEIS). ILI incidence data were analyzed in relation to age, gender, patient category as well as pathogen patterns. Multiple viral, bacterial and viral-bacterial co-infections were identified. Nose and throat swabs of active duty soldiers in the homeland country and in the NATO peacekeeping forces KFOR (Kosovo Force), as well as members of their families were tested for the presence of viral and bacterial pathogens. From October 2011 to May 2012, 416 specimens from ILI symptoms patients were collected and analyzed for the presence of viral and bacterial pathogens. Among viruses, coronavirus was the most commonly detected. In the case of bacterial infections, the most common pathogen was Staphylococcus aureus.

Background: Occupational physicians work directly with individual employees regarding diseases that has been caused or exacerbated by workplace factors. However, employees are increasingly required to travel for their work, including to tropical countries where they risk exposure to diseases they would not normally encounter at home (i.e., malaria). Such disease/s may also take days to months to incubate before becoming symptomatic, even after their return home, thus delaying and complicating the diagnosis. Proving this was an occupational disease with respective sick leave entitlement or compensation can be challenging. There is a lack of data concerning occupational diseases caused by tropical infections.Material and methods: Employee case records for the period 2003-2008 from the State Institute for Occupational Health and Safety of North-Rhine Westphalia in Germany were analysed and assessed within Germany’s regulatory framework. These records included Germany’s largest industrial zone.Results: From 2003-2008the suspected cases of “tropical diseases and typhus”, categorized as occupational disease “Bk 3104” in Germany, have decreased significantly. A high percentage of the suspected cases was accepted as occupational disease, but persistent or permanent sequelae which conferred an entitlement to compensation were rare.Conclusion: There is scope to improve diagnosis and acceptance of tropical diseases as occupational diseases. The most important diseases reported were malaria, amoebiasis, and dengue fever. Comprehensive pre-travel advice and post-travel follow-ups by physicians trained in travel and occupational health medicine should be mandatory. Data indicate that there is a lack of knowledge on how to prevent infectious disease abroad.
