The total number of 360 campylabacteriosis cases were reported in 2008 in Poland. The incidence rate was 0.94 per 100 000 population. All reported cases met criteria of confirmed case of EU case definition. No death was reported. More than 58% of patients were hospitalized. The species of Campylobacter was determined in 283 cases (78,6%): 225 cases (62,5%) were caused by C. jejuni, 47 (about 13%) by C. coli and 11 (about 3%) by C. upsalenssis. Four family outbreaks were reported in 2009 in Poland.

In Poland 8 cases of animal rabies were reported in 2008. It is the lowest number of animal rabies cases reported in Poland since the registration of the disease in the country. However, the sources of wild animal rabies are still present, mainly in the east part of the country. In Poland in 2009 the total 6 366 of people were vaccinated against rabies. Only 10 vaccinated people had contact with a rabid animal. The main reason for vaccination against rabies was exposure to an animal with not excluded rabies (5 695 cases, 89%).

With introduction of the new law on infectious diseases has decreased the number of infectious diseases subject to mandatory reporting. At the same time ambiguities in the text of the Act and no regulation defining the scope and manner of filing could affect the reduction in the number of applications especially in cases of gastro-intestinal infections caused by viruses. In 2009, a new variant of influenza A(H1N1)v has occurred in Mexico. Infection with this virus spread over all the continents causing new pandemic. In 2009 was recorded 375.4% more cases of influenza-like illness than in the previous year. Influenza pandemic strain was not much severe than the virus causing seasonal flu, although there were cases of severe pneumonia in young adults who, prior to infection had no chronic diseases. Regarding many of infectious diseases reported downward trend of incidence persisted. The incidence of diseases for which vaccines were introduced to the program of immunization in recent years (H. influenzae infection, mumps) demonstrated a clear downward trend. A serious problem remains epidemiological incidence of tuberculosis, which in Poland is almost twice higher than the average for Western Europe. Despite the reduction in the incidence of hepatitis C (with a slight increase in the number of reported infections of hepatitis B), the problem of viral hepatitis due to the its chronic character and severe complications, remains one of the most serious health problems of our society. More than three-fold increase in the incidence of hepatitis A is a signal for the rapid detection and control of outbreaks of infection with this virus and to promote preventive measures in groups with increased risk of infection. This is particularly important due to the low level of natural immunity against hepatitis A in Poland. Despite the relatively good situation of the HIV, compared with many other countries in the European region, 10% increase in the incidence should lead to the enhancement of activities to promote safe sex and other preventive measures. Regarding intestinal infections and intoxications is observed decline in the incidence of salmonellosis, with an increase in the incidence of infections caused by Campylobacter. The observed increase in the number of reported cases of the latter disease may reflect the greater frequency of laboratory tests. Still, the incidence of infections caused by Campylobacter sp. in Poland remains strongly underestimated. Due to infectious and parasitic diseases mortality in 2009 was 8.2 per 100,000 population (from 3.8 in Podlaskie voivodeship to 12.1 in Lubuskie) and it was higher in cities (9.0) than in rural areas (6.8). As in previous years men mortality (10.0) was higher than women (6.4). Highest mortality from communicable diseases was noted among elderly people above 84 (58.4). Despite the relatively stable epidemiological situation of communicable diseases, after 1998 in Poland is observed a small upward trend in the mortality rate due to these diseases. The main reason of such increase is the growing number of septicaemia, which is indicated as the underlying cause of death.

In 2009 were notified of 451 foodborne infections and intoxications involving 5118 cases (only outbreaks involving 4 person or more) and 140 foodborne (involving 2-3 persons). S. Enteritidis were the most frequency etiological agent in outbreaks (32.2% of outbreaks 30.0% cases in outbreaks). The main vehicle of foodborne outbreaks in 2009 were meals prepared from various (> 3) raw materials of animal sources (32% of outbreaks, 18.9% cases). Of the places of food contamination, the most prevalent were private homes (10.9% of outbreaks, 5.2% of cases) and food producing farms (11.3% of outbreaks,7.6% of cases).

In Poland, 2 517 cases of neuroinfections were reported in 2009, of which 865 had bacterial aetiology, 1 244--viral aetiology, and 408-- other or unknown origin. The etiological agent was determined in 493 (57%) cases of bacterial neuroinfections. Among them Neisseria meningitidis was found in 190 cases, Haemophilus influenzae type B (Hib) in 13 cases and Streptococcus pneumoniae in 163 cases. An increasing trend in pneumococcal infections incidence has been observed since 2005, and a substantial decrease of Hib incidence, related to increasing vaccination coverage. Viral neuroinfections incidence in 2009 increased compared to year 2008. Among confirmed cases, there were 351 cases of tick-borne encephalitis. Most of the cases were reported from endemic areas of north-eastern part of the country.

The hepatitis E virus (HEV) the causative agent of hepatitis E, is a non-enveloped RNA virus. HEV is transmitted through oral consumption of contaminated food and water According to the currently knowledge now be considered as zoonosis. The main reservoir of HEV are pigs, boars and deer. For the first time HEV was isolated from animals (pigs) in 1997 in the U.S. Genetic analysis of strains isolated from pigs showed high similarity to strains HEV isolated from humans. This was the first evidence showing that HEV is a zoonosis. Further studies have shown that occupational groups e.g. veterinarians, swine breeders with close contact to pigs have an increased risk for HEV infections. The additional evidence supported the zoonotic potential of HEV were reports of acute hepatitis E after the consumption of undercooked meat from deer and wild boar. Infection of HEV in the domestic pig and wild boar population in Europe is widespread.

In total 939 HIV cases were diagnosed in Poland in 2009 (2.46 per 100,000 population), constituting a 10% increase comparing to 2008 and 33% increase comparing to the median number in 2003-2007. The total number of incident AIDS cases in 2009 registered up to the end of 2010 was 107 (incidence 0.28 per 100,000 population). There were 42 death of AIDS patients in 2009 registered up to the end of 2010. Among the newly diagnosed HIV cases an increase of the share of infections acquired through heterosexual contact (up to 7% of all cases and 36% of cases with known transmission route) and homosexual contact between men (up to 6,7% of all cases and 34% of cases with known transmission route) were observed as compared to 2008, which reflects significant changes in HIV epidemiology in Poland, where the epidemic was for many years driven by injecting drug use. Across the country HIV infection is the most frequently detected among people aged 30 to 39 years (69.8%) and among males (76.6%). In comparison to 2008, the proportion of reports without information about the possible route of transmission increased. Furthermore, the percentage of late presenters, as defined by time between HIV and AIDS diagnoses of less than 3 months, is still high (56.1% of AIDS cases), suggesting that an important proportion of AIDS incidence could be prevented by improving testing rates. The largest group among patients with AIDS are also males and people aged 30 to 39 years. 40.2% of them were probably infected through injecting drugs.

Chickenpox is a common childhood disease. It occurs sporadically in persons over the age of 15. Regardless of the fact that chickenpox is considered to be a disease of benign course, it may cause complications of different severity levels and with necessity of hospitalization. Since 2004, a high incidence of chickenpox is observed in Poland. The aim of the present article was to analyze the epidemiological situation of chickenpox in Poland in 2010 with its comparison to the situation observed in the previous years. The epidemiological situation ofchickenpox in Poland in 2010 was analyzed on the basis of aggregated data on infectious diseases published in the annual bulletins, i.e.: "Infectious diseases and poisonings in Poland in 2010" (Czarkowski MP. et al., Warsaw, NIPH-NIH, Chief Sanitary Inspectorate) and "Vaccinations in Poland in 2010" (Czarkowski MP. et al., Warsaw, NIPH-NIH, Chief Sanitary Inspectorate). In the present article the authors also referred to the Polish Immunization Programme for 2010 (annex to the statement of the Chief Sanitary Inspector of 22 October 2009). The data on the number of hospitalized persons and complications due to the chickenpox was derived from the Department - Centre for Monitoring and Analyses of Population Health Status and Health Care System (NIPH-NIH). In 2010, 183 446 cases of chickenpox were reported. The highest number of chickenpox cases was registered in mazowieckie voivodeship, the lowest--in podlaskie voivodeship. The incidence was estimated at 480.04 per 100 000 population and was significantly higher than the incidence observed in 2009 (367.2). The highest chickenpox incidence, which amounted to 4298.4 per 100 000, was reported in children aged 5-9 years. The highest number ofchickenpox cases (the peak) was reported in the period from January to June. The lowest number of cases was registered in September. The chickenpox incidence was higher in men than women and in the inhabitans of villages (498.6 per 100 000) than in persons residing in towns (468.8). The highest incidence was observed in towns with the number of inhabitants ranging from 55 to 99 thousands (532.2 per 100 000), while the lowest incidence was reported in towns over 100 thousand inhabitants (439.1 per 100 000). Overall, 1007 persons were hospitalized due to the chickenpox. A total of 31 540 persons were vaccinated, of whom 30 513 persons belonged to the age group 0-19 years. Since 2004, an increase in the number of reported chickenpox cases is observed in Poland. It is a consequence of improvement in chickenpox registration.
