We currently face the largest and most frightening pandemic in 100 years. Not since the influenza outbreak of 1918-19, during which 50 million people died, and 500 million were infected by a virus of avian origin, have we faced such a large, global epidemic.

While still far from those numbers, COVID-19 as of May 6, had infected 3.75 million people and killed 265,000.
