Just so you know:
While the global pandemic of 1918 lasted for two years, a significant number of deaths were packed into three especially cruel months in the fall of 1918.
Historians now believe that the fatal severity of the Spanish flu's “second wave” was caused by a mutated virus spread by wartime troop movements.
Also, Spanish flu struck the 20-40 age group. And 65 years and older. Some analyses have shown the virus to be particularly deadly because it triggers a cytokine storm, which ravages the stronger immune system of young adults.
It is estimated that about 500 million people or one-third of the world’s population became infected with this virus. The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States. Most in a two-month period starting in September 2018.
There was no vaccine to protect against influenza infection and no antibiotics to treat secondary bacterial infections that can be associated with influenza infections. People were asked to avoid public transportation and walk to work. Stores closed early.
(25 million died of the Black Plague that lingered on for centuries for the 1300's through the early 1900's.Vladamir Haffkine, a Jewish physician, discovered the vaccine for the black plague in 1905.)
According to Wikipedia, the 2009 swine flu pandemic was an influenza pandemic that lasted for about 19 months, from January 2009 to August 2010, and was the second of two pandemics involving H1N1 influenza virus (the first being the 1918–1920 Spanish flu pandemic).
This virus appeared to be a new strain of H1N1, which resulted from a previous triple reassortment of bird, swine, and human flu viruses
further combined with a Eurasian pig flu virus,[11] leading to the term "swine flu".[12]
The number of lab-confirmed deaths from the Swine Flu reported to the WHO is 18,449,[8] though this 2009 H1N1 flu pandemic is estimated to have actually caused about 284,000 (range from 150,000 to 575,000) deaths.[14]
A follow-up study done in September 2010 showed that the risk of serious illness resulting from the 2009 H1N1 flu was no higher than that of the yearly seasonal flu.[15
The WHO estimates that 250,000 to 500,000 people die of seasonal flu annually.[10]
So far, according to https://ncov2019.live/, as of Aug 2, 2020, COVID-19 total confirmed cases 18,025,812; total critical cases 68,752; total deceased 688,961,
total active cases 6,040,669, total recovered 11, 127, 455.
