Spanish flu was the most devastating pandemic ever recorded killing an estimated 50-100 million people worldwide, leaving major figures like medical philanthropist Bill Gates to draw comparisons to the ongoing COVID-19 pandemic.

What can the world's worst flu outbreak tell us about the coronavirus COVID-19 pandemic?

• Similarities Between Spanish Flu and Coronavirus

1. Both diseases seemed to originally come from an animal source -- Research into H1N1 Spanish flu virus genes suggests, the outbreak came from a bird. Likewise, health experts suspect an animal originally hosted the COVID-19 coronavirus strain before it started to infect humans.

2. The Spanish flu became much more dangerous after an apparent mutation. Likewise, strains of coronavirus are known to mutate relatively easily.

3. Infection Rate -- Spanish flu infected an estimated 1/3 of the global population. And although much remains unknown about COVID-19, the disease has spread rapidly from its origin in China and now can be found on every continent except Antarctica.

4. Mortality Rate -- The death rate of Spanish influenza case-fatality rate is estimated to have been greater than 2.5%. This means for every 100 recognized cases, on average more than two and a half people died. About COVID-19, one JAMA study published in February estimates the case-fatality rate at 2.3%, nearly identical to Spanish flu estimates. However, much work remains to determine the disease's true case-fatality rate.

• How Spanish Flu and Coronavirus Differ

Perhaps the most important difference between the two viral diseases comes down to historical timing. The Spanish flu pandemic coincided with World War I, which helped the disease quickly spread along with mobilized troops from place to place. In contrast, many nations have enacted travel restrictions to areas high in coronavirus COVID-19 infections with the purpose of preventing quick spread.

• What Remains Unknown About Coronavirus

Coronavirus COVID-19 has never been seen before this outbreak. As a result, there are many details about the infection that remain unknown. One of the most pressing questions is whether coronavirus will go away anytime soon.
