On The Origin Of The Home Of COVID-19 - 19

I.

This series includes, among other things, the argument that the "farming and mass slaughtering of cows, pigs, and chickens industry" markets and exports meat products that contain corona viruses (On The Origin Of The Home Of COVID-19, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18).

One of the hypotheses set forth in this series is that SARS-CoV-2 is a descendant of corona viruses that have been found in sewage for many years:

"These findings provide strong evidence that SARS-CoV can be excreted through the stool/urine of patients into sewage system, thus making the sewage system a possible route of transmission."

(Concentration and detection of SARS coronavirus in sewage, Wang 2005, Journal of Virological Methods). Wang's decade and a half old research and perceptions have proven accurate some 15 years later as the descendant virus SARS-CoV-2 (causes COVID-19) has been found in sewage systems all over the place.

In fact, in the USA it is a preferred method of SARS-COV-2 detection now:

"Sampling wastewater is therefore sampling a mix of the total population in the sewershed, and encompasses the large proportion of infected individuals that do not get tested, because they are not or only mildly symptomatic, are reluctant to get tested, are not included in the testing policy or have less access to testing. As a consequence, sewage surveillance better represents the true SARS-CoV-2 circulation in the population. Sewage surveillance is the systematic collection, analysis and interpretation of data on SARS-CoV-2 RNA in wastewater to observe (and provide an early warning of) trends in COVID-19 in the communities. Sewage surveillance has been shown to be sensitive and fast enough to provide an early warning of increasing SARS-CoV-2 in cities. This is important information to support stratified lockdown decisions. Sewage surveillance is aimed to monitor the circulation of SARS-CoV-2 communities; large communities such as inhabitants of a large city, or smaller communities, such as nursing homes, university or office campuses, prisons, and so on. It is a very cost-efficient tool for population surveillance, and also a noninvasive tool, which does not require repeated sampling of individuals (such as nursing home inhabitants) to survey for (absence of) SARS-CoV-2 circulation in that community."  

(Implementation of environmental surveillance for SARS-CoV-2 virus to support public health decisions: Opportunities and challenges, emphasis added). The CDC has guidelines for such surveillance (CDC Wastewater Surveillance Data Reporting & Analytics).

What goes into our mouths is food that comes to us from the "farming and mass slaughtering of cows, pigs, and chickens industry", and what goes out into the sewer systems indicates what came in.

II.

What comes out of us is feces and urine with viral residue of the enteric viruses, and that excrement is combined to form sewage systems.

Exactly as Dredd Blog has hypothesized ("garbage in ... garbage out").

III.

The remaining work for scientists is to isolate the microbe or microbes that are being massacred by toxic chemicals / antibiotics used by the "farming and mass slaughtering of cows, pigs, and chickens industry" so that they are not destroyed along with pathogens.

Avoiding "firing a shotgun into a crowd with one crook in it" is a worthy endeavor.

Update

"Early phylogenetic analyses suggest that SARS-CoV-2 may have evolved between October–December 2019 [9-11].

  1. Porked ...

    "The new policy allows imports of pork with acceptable residues of ractopamine, a drug added into animal feed that promotes the growth of lean meat that some farmers use in pigs.

    The drug is banned by the European Union, but is legal in the United States.

    Demonstrators marched in front of the Presidential Office Building as part of an annual labor march.

    “I came here today to oppose the import of ractopamine," said Kelvin Chen, a 54-year-old computer engineer who was marching. "I feel these days many who do business are not ethical. If they mix the U.S. pork with Taiwan pork and then sell it to us average consumers, we as individuals have no way to know the source of the pork.” (link)
