Ebola virus disease (EVD) is a zoonosis of high virulence in humans. Current epidemic in West Africa is the largest EVD epidemic reported so far, exceeding the number of cases notified and geographical regions affected. This article discusses selected aspects of Ebola virus biology and ecology which are of significance for the processes of primary infection in humans and the spread of epidemic in population. A special attention was drawn to the issues essential for the diagnosis of infection and safety of testing.

Thiomersal is an organomercury compound known for its antiseptic and antifungal properties and used as an antibacterial agent in pharmaceutical products, including vaccines and other injectable biological products. In recent years, concerns about the possible link between immunization with thiomersal-containing vaccines and autism development have grown. ⋯ There are no contraindications to the use of vaccines with thiomersal in infants, children and non-pregnant women. The risk of serious complications associated with the development of diseases in unvaccinated individuals far outweighs the potential risk of adverse consequences associated with immunization with thiomersal-containing vaccines.

The National IHR Focal Point is a center set up by each Member State of the World Health Organization (WHO) in accordance with the International Health Regulations (2005). The International Health Regulations (IHR) were adopted on 23 May 2005 at the World Health Assembly and entered into force since 15 June 2007 as the legal instrument designed to help protect all countries from uncontrolled international spread of diseases and other urgent public health threats. According to Article 2 of IHR the purpose and scope of these Regulations are to prevent, protect against, control and provide a public health response to the international spread of disease in ways that are commensurate with and restricted to public health risks, and which avoid unnecessary interference with international traffic and trade. ⋯ The task of the National IHR Focal Point in Poland is also the dissemination of WHO and ECDC notifications, including recommendation and risk assessment documents. The aim of this work is the review of WHO and ECDC notifications received by National IHR Focal Point in Poland in the period from 2010 to 2015 which were related to emerging infectious diseases not covered by routine vaccination programs or for which there are no effective vaccines that have occurred in the WHO European Region. The review includes verotoxin-producing Escherichia coli O104: H4 infections, MERS-CoV infections, Ebola virus disease, malaria, dengue fever, West Nile fever, chikungunya and cholera.

Evaluation of the epidemiological situation of imported malaria in Poland in 2013 compared to the data from previous years. ⋯ Despite a significant increase in the number of cases compared to previous years, the total number of imported malaria remains low. Persistent large number of delays in the diagnosis and a high percentage of severe malaria cases indicate the need to raise doctors awareness of the possibility of malaria incidence. Travelers should be also constantly reminded of the need to inform their GPs about the stay in the malaria endemic areas in the event of fever after returning.

An analysis of HPV vaccination strategies and vaccination coverage in adolescent girls worldwide for the last eight years with regard to potential improvement of vaccination coverage rates in Poland. ⋯ Disparities in HPV vaccination coverage rates in adolescent girls worldwide may be due to different strategies of vaccination implementation between countries. Having compared to other countries, the low HPV vaccination coverage in Polish adolescent girls may result from the lack of funding at national level and the fact that vaccines are administered in a primary health care setting. A multidimensional approach, involving the engagement of primary health care and school personnel as well as financial assistance of government at national and local level and the implementation of media campaigns, particularly in regions with high incidence of cervical cancer, could result in an increase of HPV vaccination coverage rates in Poland.
