Brazilian researchers on discovery of COVID-19 virus in November sewage
A Brazilian research team found samples of the new coronavirus in the sewer system of the southern city of Florianopolis back in late November 2019, three months before the first COVID-19 case was officially recorded in the country on February 26.
The researchers from the Applied Virology Lab at the Federal University of Santa Catarina (UFSC) published their findings in a paper on June 26. CGTN’s correspondent in Brazil, Paulo Cabral, has spoken to two leading researchers on the team for more details about their discovery.
“We are sure of what we found in the November sample. It is the SARS-CoV-2 virus. We have no doubts about that,” Patricia Stoco, a geneticist at the lab, told CGTN.
“We are now effectively working on sequencing the whole genome of these samples, so we’ll be able to compare the sequencing of the virus found in our samples from late November with that of the virus now actually circulating and infecting people,” she said.
“Doing that we could maybe detect mutations that could possibly explain the increase in the number of cases now,” she added, stressing that comparing the full genetic sequencing is important to deepen understanding about the virus.
Gislaine Fongaro, a virologist at the university, explained how the research was conducted. She said the samples were collected from raw sewage in the pipes en route to the treatment plant.
“These samples were collected monthly between October 2019 and March 2020. So we take the samples to the laboratory and freeze them. That’s why we could go back over them now – they were frozen,” she said.
“Results came back negative for SARS-CoV-2 in the samples from October. And then negative again in the early November samples. But then results came back positive for the first time for a sample from November 27. And then all samples tested came back positive until March 2020,” she explained.
She said it’s possible that if they went further back, they could find more positive results for the novel coronavirus.
“It would be very important if we could review samples dating back to the beginning of the year [of 2019],” she said, adding that she hopes their research will encourage other teams who may have access to older samples to check them, and also encourage researchers to look into other older clinical samples taken from patients, which could also help tell the story of the virus.
“Because if we found this in the sewer, that’s because people were already carrying the virus. That means there were already people who were infected but were not diagnosed because we did not know about the virus back then,” she noted.

EU Cautiously optimistic on Syria engagement – Official
Irish foreign minister Simon Harris said on Monday that the European Union (EU) “is cautiously optimistic on Syria engagement” but called for more deeper engagement to strengthen relations with the country.
Harris said this at a news conference held at the EU Headquarters in Brussels, the Belgian capital.
“It’s early days, but I think there are signs of optimism. But it is important that we continue to engage.
“I don’t think it would be a good scenario if any other geopolitical actors and forces engage with Syria and for the European Union not to be in a position to intensively engage with them,“ he said.
In her remarks, Ms. Kaja Kallas, the Vice-President of the EU described Syria’s future as fragile but said that the bloc needed to take the right steps.
“But of course, we need to see the right steps as well. Right now, they’re saying all the right words, and they are doing also the right things.
“Therefore, we have this set step-for-step approach, and if they take the steps, then we are willing to take the steps as well,’’ she said.
On the war in Gaza, Harris said President Donald Trump and his team are very much a party to the ceasefire deal between Israel and Hamas after the intensive work that was put in.
He conceded that the Trump administration put in a lot of effort to arrive at a ceasefire agreement in the days before his assumption of office for a return to the White House.
“I think that was important and there is no doubt that the intensive work invested by the Trump administration played a very significant role in helping to bring about a ceasefire – a ceasefire that has now seen a cessation of hostilities, the killing, and the bombings.
“Also, that has seen the flow and has seen hostages being released. It’s really important that the ceasefire is in place.
“It is also important, though, to acknowledge in that ceasefire agreement itself, it does talk about people being able to return, and therefore, I think it’s important that we’re consistent in the approach that we take.
“The priority, I think, needs to be on implementing to the letter, the ceasefire agreement.”
