H1N1 DISCOVERED IN POULTRY. -- (Agri Markenting)
....The current H1N1 virus strain is a mixture of human, pig and bird genes and has proved to be very contagious but no more deadly than common seasonal flu viruses.
.....However, it could theoretically become more dangerous if it adds virulence by combining with H5N1, commonly known as avian flu, which is far more deadly but harder to pass along among humans.........
This phenomenon is called genetic reassortment or recombination -- which may happen in case of simultaneous viral infections of any of the hosts.
