Influenza Pandemic

Influenza virus moves to humans initially by infecting the animals, where the animals infect the humans in some cases eventually spreading through human contact resulting in an epidemic. This has been established by World Health Organization. Influenza virus is generally transmitted through wild birds to other species which leads into an outbreak of human influenza pandemic. New human influenza strains are the result of emergence of different strains of the viruses in poultry and pigs. Influenza pandemic is epidemic of influenza which spreads and infects large number of population worldwide leading to high levels of mortality. Unlike regular epidemics of influenza, it does not occur regularly.
