维基百科关于猪流感的解释（英）：
Swine influenza (also swine flu) refers to influenza caused by any strain of the influenza virus endemic in pigs (swine).Strains endemic in swine are called swine influenza virus (SIV).
Swine flu is common in swine and rare in humans.People who work with swine,especially people with intense exposures,are at risk of catching swine influenza if the swine carry a strain able to infect humans.However,these strains rarely are able to pass from human to human.Rarely,SIV mutates into a form able to pass easily from human to human.The strain responsible for the 2009 swine flu outbreak is believed to have undergone such a mutation.[1] This virus is named swine flu because one of its surface proteins is similar to viruses that usually infect pigs,but this strain is spreading in people and it is unknown if it infects pigs.
In humans,the symptoms of swine flu are similar to those of influenza and of influenza-like illness in general,namely chills,fever,sore throat,muscle pains,severe headache,coughing,weakness and general discomfort.The strain responsible for the 2009 swine flu outbreak in most cases causes only mild symptoms and the infected person recovers fully in a few days.
Of the three genera of human flu,two are endemic also in swine:Influenzavirus A (common) and Influenzavirus C (rare).[2] Influenzavirus B has not been reported in swine.Within Influenzavirus A and Influenzavirus C,the strains endemic to swine and humans are largely distinct.
