Story notes

 * This episode had Doctor Who fans pointing out the parallels between the fictional bacteria Praxeus and the real world Coronavirus. The real virus was discovered in December 2019 and spread in 2020, notably after the episode was filmed.
 * The climatic moment of the story in which the Doctor desperately saves Jake Willis from certain death in an exploding spacecraft after he sacrifices himself to destroy Praxeus made fans recall the climatic death scene of former companion Adric in Earthshock from 1982 in which the Fifth Doctor was unable to save Adric due to the Cyber-Leader damaging the control console of the TARDIS, resulting in Adric plummeting towards Earth, being the reason the dinosaurs went extinct.
 * The Doctor's opening monologue places Praxeus as taking place "early in the third decade of the 21st century."
 * This story marked the first television role in any licensed Doctor Who media given to a Brazilian actress, Gabriela Toloi.
 * This story marked the last time Millennium FX worked on an episode of the show.
 * Soyuz spacecrafts, as the one seen in the story, exist in the real world.

Production errors

 * As the Doctor is standing in the TARDIS doorway watching Yaz and Gabriela leave, it is obvious that the interior of the TARDIS is just a photo pasted onto the back wall.

Continuity

 * Team TARDIS are investigating the three separate distress signals received by the TARDIS. (TV: Fugitive of the Judoon)
 * The Doctor briefly entertains the possibility that the Autons might have taken over the world's discarded plastic. In fact, the Nestene Consciousness recently did take over the North Atlantic garbage patch, with ongoing plans for world domination through Bakin Petrochemicals. Rhys Williams took care of this threat in the short term. (AUDIO: Sargasso)
 * Team TARDIS use comm dots. (TV: The Tsuranga Conundrum)
 * When the TARDIS materialises around Jake, he appears in the interior. (TV: The Parting of the Ways, Dinosaurs on a Spaceship, Let's Kill Hitler)
