The 1889–1890 flu pandemic (October 1889 – December 1890, with recurrences March – June 1891, November 1891 – June 1892, winter 1893–1894 and early 1895) is a deadly influenza pandemic that kills about one million people worldwide.
The outbreak is dubbed "Asiatic flu" or "Russian flu" (not to be confused with the 1977–1978 epidemic caused by Influenza A/USSR/90/77 H1N1, which will also be called Russian flu).
For some time the virus strain responsible will be conjectured (but not proven) to be Influenza A virus subtype H2N2.
More recently, the strain will be asserted to be Influenza A virus subtype H3N8.
