Human and animals influenza is caused by the virus possessing 8 RNA segments in the genome. The segmented nature is critical structural feature that allows influenza viruses to undergo genetic reassortment. Pigs are important reservoir of influenza viruses because they express two types of receptors in the trachea which can bind swine, human and avian influenza viruses during infection. Therefore reassortation of viruses’ segments from different origin and subtypes can occur and facilitate in this way the generation of the strains with pandemic potential. Pigs can infect human with influenza virus directly which was several times confirmed. However the monitoring of pig care takers health indicate that it happened occasionally. In April 2009 the first cases of influenza, caused by the new strain of influenza type A H1N1, possessing genes of swine origin of unknown combination, occurred in North America. Within few days influenza spread and over 1000 people in 21 countries developed the illness, including 27 deaths. New A H1N1 strain possesses pandemic potency and is transmitted between humans only. Up to now none of the cases reported worldwide have had any direct contact with pigs. More over infected person introduced the mutant into the pig herd which may increase the risk of further reassortation. Data concerning the epidemic of A H1N1 strain are presented in this paper.
