The swine flu outbreak of 2009 is thought to be due to such a mutated strain of the SIV. The current outbreak is known as swine flu only because one of the surface proteins of the tested virus is comparable to the one which infects pigs. It is still unknown if this is presently infecting pigs though it's clearly spreading among folks, leading the World Health Organization to raise the Phase 4 pandemic alert.

This new strain in charge of the outbreak has been revealed to be a re-assortment of strains of the influenza A virus subtype H1N1.
H and N antigens of influenza A virus to endure regular antigenic variation.

Transmission of novel influenza A H1N1 is being studied as a part of the continuing outbreak enquiry, but limited data available indicate that this virus is transmitted in techniques similar to other influenza viruses.

Seasonal human influenza viruses are thought to spread from individual to individual primarily through large-particle respiratory droplet transmission ( e.g, when an infected person coughs or sneezes near a susceptible person ).
A H1N1 cases should be considered most likely infectious. The guestimated incubation period is not known and could range between 1-7 days, and much more likely 1-4 days.



Complication the most typical complication of influenza is pneumonia primary influenza viral pneumonia, secondary bacterial pneumonia, or mixed viral and bacterial pneumonia

Other pulmonary complications associated with influenza include worsening of prolonged obstructive pulmonary illness and exacerbation of protracted bronchitis and asthma. In children, influenza infection may present as croup.
