Oregon made a door-to-door visit to provide coronavirus testing. I don’t know how many people had a positive reaction.

Ah New research by researchers at Oregon State University It shows that the spread of coronaviruses in Corvallis is not widespread, although important details remain a mystery.

University officials said Thursday that preliminary findings suggested 2 out of every 1,000 inhabitants of a university town may be infected I was infected with the novel coronavirus on the weekend of April 25.

But the university refused to state how many of the 455 tested during the first weekend’s collection were actually positive.

The estimated prevalence in this study is based on these private test results and modeling. It is unclear how many positive results this study had, but the number of confirmed infections across Benton County has increased over the four days since April 25.

Bendall Giel, an associate professor at the University of Science who heads the project, defended the decision not to release a particular tally. Dargier argued that estimates of prevalence were important.

The university’s estimate is “much lower than that experienced in parts of the United States,” he said. But Dargier said parts of Oregon should not be used as evidence of a reopening too soon.

“It would be wrong to think, ‘Oh, two in 1,000, let’s restart,” “he said. “It’s not the way people think.”

This is the first study in Oregon and provides the only real insight to date on how widespread the virus can spread among previously untested people. University officials said early findings indicate the need for further testing that should help identify asymptomatic people whether they are infected.

Estimates of surveys from Corvallis to other Oregon are difficult to estimate.

According to state statistics, the widespread tests performed in Benton County include research results and people who asked doctors to test them, with only 2% of people being infected with coronavirus. This is more than half of the statewide average of just over 4%.

The university project officially started on April 25, sending trained field staff to randomly selected households in Corvallis every weekend for four weeks to see if residents could be tested for coronavirus. I will. Individuals who agree use a cotton swab to take a sample from their nostrils.

According to simple calculations, 1 out of 455 people tested positive the first weekend, but Dargier refused to disclose that number. Asked if there may be no one who tested positive, he said the total number of positive tests has not been announced so far.

It is clear that the prevalence of coronaviruses in Benton County is not zero, as the Oregon Health Authority reported that the population responded positively. Whatever they are, positive tests discovered during the study, Darjeel, need to incorporate modeling to determine the overall prevalence.

Mr Dargier said part of the decision not to disclose the total number of positives from the study was to protect the privacy of individuals. He didn’t say how many positive results would be needed before the university announced the tally. However, he noted that the Oregon Department of Health did not release a specific count of postcodes under 10 infections.

“We are always reassessing and we want to be as transparent as possible,” he said.

More quotes from Corvallis will be released next week. Oregon authorities collected about 900 samples last weekend. These findings will be included in the next weekly snapshot.

State figures show positive test results rising from 32 to 44 in Benton County since May 2. However, the number, if any, of new infections found as part of a university study, as opposed to those seeking medical examination, is unknown.

Going forward, this study will no longer be aimed at collecting samples from 960 people per week. Instead, authorities set a goal of collecting weekly samples from 8 to 12 households in 30 regions. It can bring tests from about 600 people a week, as Dargier said.

University officials are also considering postponing the final week of the collection at Corvallis from 16 May to 23 May.

This article was updated to clarify that the total number of infections detected from April 25 to the next day increased by 4 across Benton County.
