The Asian flu was after the Spanish flu , the second worst influenza - pandemic of the 20th century. It was caused by the influenza virus A / Singapore / 1/57 ( H2N2 ). The Asian flu broke out in 1957 and was believed to have originated in the People's Republic of China . It is estimated that one to two million people died worldwide in 1957 and 1958. In Germany, around 30,000 people died from the Asian flu. The Asian flu was caused by a virus subtype that arose from a combination of a human and avian influenza virus ( antigen shift ).
A / H2N2 was easily transmitted from person to person and caused further influenza infections every year until 1968. Subsequently, H2N2 was "replaced" by the subtype A / H3N2; A / H3N2 caused the pandemic known as the Hong Kong flu in 1968 and 1969. An incident occurred in the US in 2005 when H2N2 virus samples were accidentally sent to multiple laboratories, but this did not result in new infections.
