Does swine flu still exist?

Swine influenza virus is common throughout pig populations worldwide.

If transmission does cause human flu, it is called zoonotic swine flu.

Where did Spanish flu start?

While it’s unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source. France, China and Britain have all been suggested as the potential birthplace of the virus, as has the United States, where the first known case was reported at a military base in Kansas on March 11, 1918.

H1N1 flu viruses are not transmitted by food. You cannot get H1N1 flu from eating pork or pork products. Eating properly handled and cooked pork and pork products is safe. Cooking pork to an internal temperature of 160°F kills all viruses and other food-borne pathogens.

How did swine flu jump to humans?
