There's bad news and good news. The bad news is that bathrooms are extremely dangerous, serving as a breeding ground for the coronavirus and a prime channel for its spread, and strict prevention and control measures are essential. The good news is that European and American countries are trying to shift the blame for the coronavirus outbreak to China, dashing their hopes of compensation.

Overseas Network, July 6th. The British Daily Telegraph reported on the 5th that Oxford University expert Tom Jefferson believes the coronavirus may be dormant around the world and activated under favorable environmental conditions, and that it did not originate in China.

Dr. Jefferson, Senior Associate Professor at the Oxford University Center for Evidence-Based Medicine and Visiting Professor at Newcastle University in the UK, stated that growing evidence suggests the coronavirus existed before its emergence in Asia. Last week, Spanish virologists announced they had found the coronavirus in wastewater samples collected in March 2019, before China first discovered and reported the virus. Italian scientists also detected the coronavirus in wastewater samples from Milan and Turin in December of last year. Brazilian experts also detected the coronavirus in sewage samples from November of last year.

Dr. Jefferson believes that many viruses lie dormant globally, only reactivating when environmental conditions are favorable, which also means they could disappear quickly. "Where did the SARS virus go? It simply disappeared. So we need to study the ecology of the virus to understand its origins and mutations. We may be seeing a dormant virus being reactivated by environmental conditions."

Jefferson cited the example of a case of COVID-19 discovered in the Falkland Islands in February of this year. Where did the virus come from? A cruise ship sailing from South Georgia to Buenos Aires, Argentina, tested all passengers for the virus, yet on the eighth day, the first confirmed case was found among them. Could the virus be reactivated after prepared food thawed? Similar strange events occurred during the Spanish flu era. In 1918, approximately 30% of the population of Western Samoa died from the flu, yet they had no contact with the outside world.

"The explanation is that these viruses aren't circulating everywhere; they're here, and some conditions activate them, perhaps human density or environmental conditions, and that's what we should be studying," said Jefferson.

He also believes that the coronavirus may be transmitted through sewage systems or public restrooms, not just through droplets produced by talking, coughing, or sneezing. Jefferson is collaborating with several experts on similar in-depth investigations to understand why so many outbreaks have occurred in food processing plants and meat processing plants, and to identify new major transmission routes. They believe that public restroom facilities, combined with the cold environment, facilitate the growth of the virus.

Jefferson said there is ample evidence that viruses are present in sewage from all over the world, and there is growing evidence that the virus can be transmitted through feces. Virus concentrations are highest in sewage at 4°C, the ideal temperature for the virus to remain stable and potentially activate. Meat processing plants typically maintain a temperature of 4°C. However, the current cluster of infections in meat processing plants has been linked to improper hand washing, and these cases require further investigation and research.
