As some might say…

“It was the best of times, it was the worst of times…” 

These—the immortal words of Charles Dickens—could be used to describe 2020 (and now 2021).  On the one hand, COVID 19 has been on the forefront of everyone’s minds.  But in the same moment, economic shifts have created space for some to revitalize the concepts of work, creativity, and playtime. 

Thanks to the kindness and retrospection of @realGulDukat (“Dukat”, of course, being a fictional character from Star Trek: Deep Space Nine), the world now has The Complete Guide To Pandemic Focused Episodes in Star Trek. This Twitter user took some time at the very beginning of the pandemic in 2020 to document a thorough list of all Star Trek episodes that focused on the pandemic, as a way of helping the Trekkie community.

Star Trek: Discovery is a great show, but it hasn’t been around very long, so it didn’t make the list. There are some that are kind of close, like Season 3 Episode 8 “The Sanctuary,” which partially talks about a plague of locusts, and Season 3 Episode 5 “Die Trying,” which is about a health crisis and a mystery of someone who died.

In case you’re wondering, back in April Patrick Stewart said that he didn’t want Star Trek: Picard to have a pandemic storyline, TrekMovie reported. He said, in part: “I would not encourage that. This is a disturbing and frightening and sad time for many thousands of people. I would feel uncomfortable if we were to make this a theme of the second season. It is too sensitive, too upsetting, too frightening, than some of the other issues that we have dealt with, which are much more of a political nature.”

There you have it, folks: a binge-worthy list for all of sci-fi fandom.  We hope this helps you pass the time.  Stay safe, and remember to give our friend @GulDukat a follow on Twitter. And if we missed any episodes, please let us know in the comments.
