Florianópolis had the Covid-19 virus before China

The microbiology laboratory of the University of Burgos has determined that the SARS-Cov-2 was circulating in Florianópolis three months before of What his presence was known in China.
This is determined by a study conducted by this Spanish university in collaboration with the Federal University of Santa Catarina, Brazil.

The result of this work which radically change your perspective on the behavior of the virus it has already been published by the magazine Total environmental science, according to RFI France.

The researchers detected the presence of covid-19 between November 19 and 27, 2019, ninety days before the first infection in Brazil was confirmed.

The work carried out by the two universities is the first description of the presence of viral RNA in the world

“This discovery at Florianopolis, as well as other discoveries made in Paris, Milan and Barcelona, ​​shows that the virus was circulating before we realized we had a problem“The coordinator of the investigation, Alfonso David Rodríguez Lázaro, told Radio France International.
For Rodríguez Lázaro, this finding does not affect what has been scientifically proven on the traceability of Sars-Cov-2: it is a animal virus, not created in laboratory, which jumped directly or indirectly on the human being in the Chinese city of Wuhan.
The microbiologist, full professor at the University of Microbiology of Burgos, also has a degree in veterinary medicine and food science and technology and holds a degree in public health from the National School of Health.

“The virus was circulating before we realized we had a problem.”

“This is not an isolated case”, Rodriguez Lázaro said during the radio interview: “Our study was carried out in wastewater and found that a large number of people were shedding the virus in Florianópolis, in the Brazilian region of Santa Catarina, long before the first cases of contagion were reported in Brazil ”.
Likewise, other studies carried out in other university centers have shown that the virus circulated in Spain, France or Italy before the first Covid-19 patients have been detected in these countries.
In fact, in Spain himself, who took the first samples december 2019 has developed a work on the “covid tongue”, smoothing the taste buds and loss of the sense of taste, already considered a almost indisputable symptom presence of the virus in an infected patient.
The expert said on air that although the coronavirus is considered a virus which mainly affects the respiratory tract, in your investigations and analyzes of samples detected a high number of patients with diarrhea as a symptom of infection. When a person has diarrhea, they shed the virus in very large amounts: “A patient can excrete up to a billion particles per thousand liters of diarrhea,” he quantified.

Wastewater carries the virus

The Spanish expert also pointed out that study wastewater being able to draw a microbiological map could pave the way get to the virus. Instead of examining patient by patient to see who is wearing it, testing the water containing feces can provide viral traceability that can be faster or more effective: helps determine which area of ​​a city is infected.
“Dada la important información que arroja este tipo de investigación en aguas residuales, the Organización Mundial de la Salud (OMS) y la Unión Europea (UE) proponen que, para antes de finalizar el año 2021, se lleven a cabo planes de vigilancia en The that every week residual samples are taken and the stool is examined contained in them, ”reports RFI.
The researchers had stored in refrigerators wastewater from the city of Florianópolis that would be used in further studies. When the pandemic was detected, they used it to investigate viral RNA tracing.
