Clemson’s wastewater shows increased levels of Covid-19, the British variant, said the professor | Instant News

GREENVILLE, SC (WSPA) – The director of the Center for Disease Control said Wednesday that the Covid-19 variant first identified in the UK is now the dominant strain in the United States, and a Clemson University professor told 7News an analysis of the virus found in wastewater showed it was the dominant strain in the Clemson area as well.

The data from DHEC and CDC do not show the British variant predominates in South Carolina, but that is something DHEC is monitoring.

Professor Clemson and chair of the university’s environmental engineering and earth sciences department Dr. David Freedman has been monitoring the Covid-19 virus found in Clemson’s wastewater for nearly a year. He said it shows how widespread the virus is in society. Over the past three weeks, he said the British variant went from nearly undetectable to dominating.

“The newest sample we have is basically 100 percent,” he said.

The British variant appears to be more contagious than the original form of the virus, according to the CDC.

Dr Freedman said wastewater showed the virus also appeared to have spread more widely in the Clemson area in March.

According to the CDC, the British variant accounts for about nine percent of Covid-19 cases in South Carolina. This is higher in several other states, including Florida, where one in three cases is caused by a variant, according to CDC data.

“Our story is a microcosm of what’s happening globally with the spread of these variants,” said Dr. Freedman.

DHEC officials are continuing to monitor the variants and hope that there will be a reduction in stable cases in the state.

“This variant nationally, as well as in South Carolina, is the reason we encourage everyone to get vaccinated as quickly as possible,” said Dr. Brannon Traxler, who is the interim public health director at DHEC.

“This variant puts us in a race between disease spread and vaccination rates,” said Dr. Freedman.

Experts warn that even though vaccines are bringing us closer to the end of the pandemic, social distancing and disguise remain important.

Dr. Freedman likens it to running a marathon.

“You’re on mile 22, the last thing you do is stop,” he said. “You have four more miles. Finish … and that’s what we face now. “

He said a variant from South Africa had not been detected in the Clemson wastewater.

Data suggests a vaccine available in the US should provide adequate protection against the variant.

“Although we have not detected … the variant in the clinical sample, we suspect it is circulating in Idaho,” said Dr. Christopher Ball, bureau chief for the Idaho Laboratory Bureau, in a news release.

Only 239 samples from the more than 136,000 confirmed COVID-19 cases in Idaho have been sequenced so far to check for mutations, according to a news release.

“The Idaho Laboratory Bureau is on track to sequencing SARS-CoV-2 samples internally by the end of the month, both of which will speed up time to generate and expand sample sizes in our strain sequencing program. In the interim, we continue to work with clinical laboratories across the state to accept samples for sequencing. “

Evidence B.1.1.7 “British variant” underscores the need for COVID-19 safety

Finding a variant in wastewater illustrates how Idaho’s battle with the coronavirus is far from over, and safety measures such as wearing masks, washing hands and maintaining physical distancing remain essential, according to the release.

“I am grateful we have a wastewater testing program, and it can tell us that this variant is in Boise so that we are reminded, once again, that we are not out of the woods yet,” said Mayor of Boise Lauren McLean in a news release. “We will get through this, and our community will recover, if we remain vigilant about keeping our distance, wearing masks and following other health protocols.”

Wastewater testing in the city of Burlington has detected “very likely” a more contagious variant of the coronavirus that originated in Great Britain.

If confirmed, the results will mark the presence of the first known B.1.1.7 variant in Vermont, which has been found in 34 other states.

“This is a new stage of the pandemic here in Vermont,” Health Commissioner Mark Levine said in a press release Thursday. “However, this is not surprising. We were hoping that the variant would make it to Vermont, and that seems to be the case. ”

City launched its wastewater program in August and started testing for the British variant last month. Tests conducted at the city’s main processing plant – which serves the city center, Old North End, South End and parts of the Hill Section – detected “low levels” of two genetic mutations linked to B.1.1.7 Wednesday afternoon, Mayor Miro Weinberger said. .

Tests at two other processing plants in the city have not yielded any evidence of this mutation, leading city officials to conclude that while a variant may exist here, it is not spreading rapidly.

The state will work to confirm the results using samples from patients confirmed to have the British variant, according to Brian Lowe, the city’s head of innovation and who leads the testing program. The sample will then be sent for genetic sequencing.

“It may take a while before they identify [it]Either because of the process or because of the many cases they have to examine, “he said.

Weinberger said people should take precautions now to slow the spread of the variant. He suggested that residents wear higher quality masks or even double masks, as recommended by the federal Centers for Disease Control and Prevention.

“There is a belief that the public health measures that have worked to keep the virus at bay in the past are still valid,” he said. “Now, people just need to be very vigilant and focus on implementing it.”

British variant of COVID-19 found in Bend | waste water Corona virus | Instant News

A highly contagious strain of COVID-19, a British variant, has been found in wastewater samples taken from the Colorado Avenue collection point in Bend, state scientists said Friday.

The samples were taken on December 22, and nearly a month later genome sequencing detected the variant, said Brett Tyler, director of the Oregon State University Center for Genome Research and Biocomputing.

“We all know that Bend is a tourist magnet,” said Tyler. “That’s a challenge for your community. That’s how the virus spreads, through travelers. We suspect that’s how it got there. “

This variant has also been detected in Yamhill County and in two individuals in Portland. Two of the three people didn’t travel, Tyler said. The British variant doesn’t make people sicker, but it is spreading faster and could affect vulnerable communities, he said.

George Conway, director of Deschutes County Health Service, said on Friday that it was only a matter of time before the variant was detected in the region.

“We anticipate that eventually we will detect it in Deschutes County,” Conway said by email. “Various evidence suggests that the British variant (B.1.1.7) is more efficiently transmitted than other variants of the virus that causes COVID-19. That means it’s increasingly important to take precautions to slow the spread. “

According to modeling by the US Centers for Disease Control and Prevention, this variant will continue to grow in early 2021, likely becoming the dominant strain by March, Conway said.

The current vaccine appears to be quite effective in immunizing people against this strain, as is the case with a strain currently more common in North America.

Detection in wastewater samples is an effective way of seeing how common the virus is in society, he said.

A team of students and researchers from Oregon State University are heading to Redmond this weekend to conduct a randomized Team-based, Community-level Coronavirus Epidemic Assessment in 30 neighborhoods. Wastewater samples from Redmond and Bend will also be collected at that time, Tyler said.

“Even though the vaccine has been launched, the emergence of this new variant makes people need to remain vigilant in wearing masks, limiting contact with other people, maintaining distance and washing hands,” said Tyler. “And they need to be vaccinated.”

Britain is expanding surveillance of viral waste | Instant News

The UK is expanding a surveillance system that detects COVID-19 in sewage after trials helped alert local authorities to increasing levels of the virus in municipal wastewater.

The UK Department of Health and Social Care has announced that researchers last month used a technique, known as wastewater epidemiology, to successfully identify a new cluster of infections in the city of Plymouth in Southwest England.

The local outbreak was caught before symptoms appeared and had not yet been detected by the UK’s testing and tracking system. The alert was forwarded to the local council and the National Health Service, which contacted people in the area to warn of an increase in cases.

The UK government-led program, which started in July, will now expand to 90 sewage treatment sites that collectively serve more than a fifth of the UK’s population.

The government hopes that this will become an early warning system for the regional spike in COVID-19 cases.

“Wastewater monitoring and sampling offers another tool to help us identify outbreaks early on, helping NHS Test and Traceability and local authorities target hotspots quickly and effectively,” said Health Minister Matt Hancock.

Yang Zhugen, a lecturer in sensor technology at the Cranfield Water Science Institute which is part of the UK program, said the genetic material from the virus could be detected in sewage long before victims of the new plague fell ill.

“Even if people are in the early stages of infection, without symptoms, their stool can still contain viral particles,” Yang told China Daily in a previous interview.

Epidemiologists are increasingly using wastewater testing to track levels of use of illegal drugs, pharmaceuticals and other chemical compounds over the past few decades. Recently, scientists have begun exploring similar techniques for monitoring pathogens, including influenza, polio, and sexually transmitted diseases.

Researchers in the Netherlands managed to detect the new coronavirus in Utrecht in early March, weeks before the city’s first confirmed cases of COVID-19. Separate testing confirmed the presence of the virus at waste disposal sites elsewhere in Europe, as well as in the United States, South America, Asia and Australia, prompting several governments to initiate wastewater surveillance programs.

This method is also used with frozen waste samples, helping scientists determine a timeline for the spread of the virus. Ancient waste samples from Spain, Italy and Brazil show that the novel coronavirus was circulating globally well before the first documented cases of COVID-19 in China, in late December 2019.

David Graham, a professor of ecosystem engineering at Newcastle University and project leader on the UK program, said that while more investment is needed to improve methods for calculating COVID-19 in wastewater, initial results are “very promising”.

“Wastewater virus levels are clearly higher in places with higher cases of COVID-19, and we are now working with colleagues across the UK to support predictive tools for public health protection,” Graham said.
