TORONTO -- A passage from author Dean Koontz鈥檚 1981 fictional novel 鈥淭he Eyes of Darkness鈥� has gone viral for purportedly predicting the real-world outbreak of the novel coronavirus.

Segments of the novel have been shared widely on social media over the last week, showing eerie similarities between the COVID-19 virus and the book鈥檚 fictional outbreak called 鈥淲uhan-400.鈥�

鈥淭hey call the stuff Wuhan-400 because it was developed at their RDNA labs outside of the city of Wuhan,鈥� reads a passage from the book, which can be seen on Amazon鈥檚 preview of the paperback edition of the novel

While the novel includes mention of Wuhan, China, the epicentre of the coronavirus outbreak, the book鈥檚 fictionalized outbreak is far from reality.

For starters, the 鈥淲uhan-400鈥� virus from the novel is a human-made biological weapon. The coronavirus is not, despite online rumours suggesting the new virus was created in a lab early on in the outbreak.

Fact-checking website Snopes points out that in the novel, the 鈥淲uhan-400鈥� virus had a 100 per cent fatality rate, whereas the current coronavirus fatality rate sits at about two per cent.

The fact-checking website also notes that while the 2008 publication of the book mentions Wuhan, other iterations of the book used a different name for the fictional weapon.

鈥淲hen we searched a 1981 edition of this book available via Google Books we found no references to 鈥淲uhan.鈥� In that edition, this biological weapon is called 鈥淕orki-400鈥� after the Russian city where it was created,鈥�

鈥淲e鈥檙e not entirely sure when or why this change occurred. From what we can tell, the biological weapon was originally called 鈥楪orki-400鈥� when this book was published in 1981. But by 2008, the name had been changed to 鈥榃uhan-400.鈥欌��
