Flu Illness
Swine Flu Caused By Vaccine
Mutated strains of B are resistant to neuraminidase inhibitor therapy, researchers reported, and may have the ability to cause a pandemic. Widespread use of neuraminidase inhibitors, currently the only available antiviral defense against influenza B, may have led to the emergence of viral variants with The virus is easily transferred and can survive on a range of environmental surfaces.

E.g.
how much transmission takes place through indirect contact, and what is the relative contribution of aerosol transmission under normal conditions?The recent attention devoted to human in the context of a possible pandemic has identified a surprising number of research gaps, some of which concern issues of fundamental importance for preventing or reducing transmission. 2. How important in influenza are indirect and aerosol transmission?From molecules to physiology Our data show that both RH and temperature do indeed affect the frequency of virus among guinea pigs, although via apparently differing mechanisms.
