Money quotes: 

"In an interview with AFP, OIE Director General Bernard Vallatdescribed the virus as a "cocktail" of four different strains."

"The OIE noted that past epidemics of human influenza epidemics with animal origin had been named after their geographical origin, such as Spanish flu or Asian flu.

"It would be logical to call this disease 'North American influenza'," it suggested."
