Pertussis in Poland in 2017.

Introduction: After the introduction of compulsory pertussis vaccination in Poland in 1960, there was a sharp decline in the incidence of this disease. For several years, however, an increase in the number of reported cases has been observed. In 2015 and 2016, the incidence was 12.

Tetanus in Poland in 2017.

Introduction: In the last decade, the number of tetanus cases in Poland has not exceeded 20 cases. Since 1984, neonatal tetanus has not been reported.

Objective Of The Work: The aim of the study is to present the data of epidemiological surveillance of tetanus in 2017 in a historical perspective, taking into account the role of protective vaccination and a reference to activities for the elimination of neonatal tetanus on a global scale.

Pertussis in Poland in 2016.

Introduction: In Poland, the high incidence of pertussis has been maintained for 10 years – in 2016 it was 17,77 per 100,000 population and it was 38% more compared to the previous year. The high percentage of pertussis is still present in those who are older, who may be a source of infection for non-immunized or not fully immunized newborns and infants. The most effective prevention strategy remains the implementation of vaccinations in accordance with the current calendar.

Tetanus in Poland in 2016.

The Purpose Of The Study: The purpose of the study was to provide data on tetanus incidence in 2016 in the basic categories of epidemiological surveillance.

Material And Methods: The study is based on the individual forms of tetanus cases submitted to the NIZP-PZH Epidemiology Department and the data of the bulletin “Infectious Diseases and Poisoning in Poland in 2016.

Results: The number of tetanus cases in 2016 was 12, exactly as it was in the previous year 2015.

Pertussis in Poland in 2015.

The Purpose Of The Study: The purpose of the study is to provide data on epidemiological surveillance of the tetanus in 2015.

Material And Methods: The study is based on the individual forms of tetanus cases submitted to the NIZP-PZH Epidemiology Department and the data of the bulletin “Infectious Diseases and Poisoning in Poland in 2015.

Pertussis in Poland in 2014.

Introduction: In Poland, they are still recorded high number of cases whooping cough - five-year median for 2005-2009 and 2010-2014 are similar and amount to 5.2 and 5.5 per 100 000 population.

Tetanus in Poland in 2014.

Unlabelled: For many years the number of tetanus cases reported in Poland remaing below fifty with marked random variations. Almost all disease occur in people unvaccinated. Some of them, especially in people over age 60, are fatal.

Tetanus in Poland in 2013.

Unlabelled: Tetanus is an infectious disease which, despite the small number of cases is a permanent risk to unvaccinated people. The severity of disease is associated with high mortality especially in older age groups.

Purpose Of The Study: The aim of the paper is to present epidemiological surveillance data tetanus in 2013.

Pertussis in Poland in 2013.

Introduction: The epidemiological situation of pertussis in recent years has changed dramatically. There is a high percentage of cases of pertussis among adolescents and adults. Infected adults can be a source of infection for non-immune individuals such as infants.

Pertussis in Poland in 2012.

Introduction: The epidemiological situation of pertussis in recent years has changed dramatically. There is a high percentage of cases of pertussis among adolescents and adults. Infected adults can be a source of infection for non-immune individuals such as infants.

Tetanus in Poland in 2011.

Purpose Of The Study: Tetanus epidemiological assessment of the situation in Poland in 2011.

Materials And Methods: We used the data published in the annual bulletin "Infectious diseases and poisonings in Poland in 2011" and "Vaccinations in 2011" (NIPH-NIH-Department of Epidemiology, GIS - Department of Prevention and Control of Infectious Diseases in Humans - Warsaw 2012) and individual reports sent to the Department of Epidemiology NIPH-NIH RESULTS: In 2011 there were reported 14 cases of tetanus--(incidence 0.036/100 000) two less than in 2010.

Pertussis in Poland in 2011.

Introduction: Results of the nationwide Pertussis Epidemiology Study implemented by Department of Epidemiology NIPH-NIH in 2009-2011 showed a high proportion of cases of whooping cough in adults whose only symptom of Bordetella pertussis infection was long lasting cough. It should be noted that the infected adults pose a risk of transmission of infection to susceptible contacts such as infants.

The Aim Of The Study: To assess the epidemiological situation of pertussis in Poland in 2011, including vaccine coverage of children.

[Tetanus in Poland in 2010].

Epidemiological assessment of the incidence of tetanus in Poland in 2010 was based on the analysis of aggregate data provided by the State Sanitary Inspection and published an annual newsletter: Infectious diseases and intoxications in Poland in 2010, compiled by MP Czarkowski, E Cielebak, B Kondej, E Staszewska, Warsaw in 2011 and based on an annual newsletter: Vaccinations in Poland in 2010, compiled by MP Czarkowski, E Cielebak, B Kondej, E Staszewska, Warsaw 2011. A more accurate characterization of disease was based on the individual reports sent to the Department of Epidemiology, NIPH-NIH. In the last decade the incidence of tetanus has remained below 0.

[Pertussis in Poland in 2010].

Introduction: Pertussis is an acute infectious disease of the upper respiratory tract. It is the infection of the re-emerging character and affects infants, youth and more frequently adults. The results of the Nationwide Surveillance Study of Pertussis conducted at the Department of Epidemiology (NIPH-NIH) in 2009-2011 confirmed the high incidence of pertussis in adults, among whom the only symptom of Bordetella pertussis infection was prolonged cough.

[Pertussis in Poland in 2009].

In 2009, 2 390 cases of pertussis were reported in Poland. The incidence 6.3 per 100 000 was higher, 9.

[Pertussis in Poland in 2008].

In 2008, 2 163 cases of pertussis were reported in Poland. The incidence 5.7 per 100 000 was higher, 9% more compared to the last year (5.

[Chickenpox in Poland in 2007].

In 2007, 160,174 cases of chickenpox were reported in Poland. The incidence 420.2 per 100,000 was higher compared to 2006 (370.

In 2007, 4,147 cases of mumps were reported in Poland. The incidence 10.9 per 100,000 was lower compared to 2006 (39.

The effectiveness of vaccination with whole-cell pertussis vaccine by age group in Poland 1996-2001.

Recurrence of pertussis in highly vaccinated populations has been observed in many countries. Two mechanisms have been proposed to explain it: a shift in incidence towards older age groups in which the protective effect of vaccination is diminished; and vaccine-induced changes in genomic and immunological characteristics of circulating strains of Bordetella pertussis, which become different from vaccine strains, thereby reducing vaccine efficacy. Marked increase in the incidence of pertussis has been observed in Poland since 1997, following a decade of stability at a low level.
