At some point in the not too distant future, people will struggle to remember what life with COVID-19 was like.

According to the CDC, about 500 million people became infected with the Spanish flu, around 100 years ago. The death count was at least 50 million people worldwide, with about 675,000 of those deaths happening in the United States. But, until March of this year, most of us were hard-pressed to remember anything about the Spanish flu.
