Localsation

The origin of this new strain is unknown

is due to an apparently virulent new strain produced by Reassortment from one strain of human influenza virus, one strain of avian influenza virus, and two separate strains of swine influenza.

Transmission and symptoms

In humans, the symptoms of swine flu are diarrhea and vomiting.

It passes with apparent ease from human to human, an ability attributed to an as-yet unidentified mutation. Influenza spreads between humans through coughing or sneezing and people touching something with the virus on it and then touching their own nose or mouth.
Swine flu cannot be spread by pork products, since the virus is not transmitted through food.
Diagnosis can be made by sending a specimen, collected during the first five days for analysis.

Prevention and treatments

frequent washing of hands with alcohol-based products
Social distancing is another tactic. It means staying away from other people who might be infected
vaccines against the new strain are being developed and could be ready as early as June 2009.

If a person becomes sick with swine flu, antiviral drugs can make the illness milder and make the patient feel better faster.
They may also prevent serious flu complications.
