A yet-unreported outbreak of the dreaded norovirus could be blamed on a massive infiltration of China’s vulnerable web browsers. The reason? The government is on an operation to spy on Chinese internet users.

While the exact cause is unclear, it appears that the origin of a global outbreak of the illness is the Global Dictionary of Common Ailments website. In the past several days, major social media platforms and western news outlets have reported that the hugely popular “curious disease” is spreading fast around the world — causing no end of disruptions and major cancellations at airports and hotels.

It appears the virus is actually called “commutative virus” and is therefore very similar to the internet version of the coronavirus, a viral pathogen that can cause the illness norovirus.

Curious Disease began spreading on Chinese social media over the weekend, and the virus has since spread to 29 other countries. The first reported cases were detected in the Middle East, around 5 months ago. Doctors are still trying to figure out exactly how many people are infected by the virus.

It appears that the emergence of “commutative virus” on Chinese social media was based on a viral tweet by SenseVentures.com, which revealed that the official registry of viral disease includes three distinct names: Coronavirus, Deep Gulf Syphilis Virus, and Patient Zero.

The official registry, according to the post, also has entries for cases of HIV/AIDS, Epstein Barr Virus, Ebola Virus, and Salmonella.
