SARS-CoV-2 in Barcelona sewers

A parody (modified image; yes, I occasionally photoshop as well!) I made based on the cover of Stephen King’s novel “It”, about a monster lurking in New England sewers. Not meant as copyright infringement. You can buy the book here.

A quick post based on a Twitter thread I did this afternoon.

Several people asked me to say something about a rather fantastical finding, that SARS-CoV-2 might already have been lurking in Barcelona sewers in March 2019, a year before the first COVID-19 case was reported in Spain.

The Octopaper

A follower on Twitter asked me to look at two identical papers. I agreed that they looked very similar, did some searches, and found six more. All eight papers presented the same survival curves, table values, and similar line graphs. But they were published in different journals by different authors, at different institutes, on different patients, and different cancers.

In this blog post, I present to you the Mysterious Case of the Octopaper.
