Deaths from the 1889–1890 flu pandemic

Deaths from the 1889–1890 flu pandemic, a deadly influenza pandemic that killed about 1 million people worldwide. The outbreak was dubbed "Asiatic flu" or "Russian flu" (not to be confused with the 1977–1978 epidemic caused by Influenza A/USSR/90/77 H1N1, which was also called Russian flu). For some time the virus strain responsible was conjectured (but not proven) to be Influenza A virus subtype H2N2.^[1][2] More recently, the strain was asserted to be Influenza A virus subtype H3N8.^[3]
