A new federally-supported study attributes the widespread Covid-19 testing to a new study that found and prevented asymptomatic transmission among nearly 2,000 Marine Corps recruits, which provides more evidence Shows that frequent testing can help contain the virus.
Dr. Stuart Sealfon is the senior author of the paper and a neurologist at Icahn School of Medicine at Mount Icahn. The Sinai Peninsula of New York City said the study shows that public health measures need to be supplemented by extensive testing to control the coronavirus.
He said in a telephone interview: “You need to do everything possible to take all these infection control measures, and you need to supplement or integrate them, and conduct as many tests and as many tests as possible.”
Many epidemiologists and public health experts have repeatedly called on the Trump administration to expand the scope of testing nationwide. Despite the increase in testing, Adret. Brett Giroir, Assistant Secretary of Health and Trump Administration virus testing expert, said there is no need to test people who are asymptomatic.
Sealfon said the new study, published on Wednesday, demonstrates the importance of frequent testing as a supplement to infection prevention measures.
The research was funded by the Defense Health Agency, the Naval Medical Research Center, and the Defense Advanced Research Projects Agency. The research objects were 1,848 Marine Corps recruits who received basic training on Paris Island, South Carolina from May 12 to July 15. The average age of the participants was 19, the study said.
According to the study, before receiving basic training, recruits should be required to be isolated at home for 2 weeks, and then be supervised on the university campus for 2 weeks. Before entering Paris Island, every recruit must show a negative Covid-19 molecular test. After entering, the recruits are also required to comply with public health guidelines, including wearing masks and staying away from society.
The study said that in order to study the asymptomatic transmission of the virus in relatively young people, the researchers used nasal swab molecular testing methods on all participants within two days, seven days, and fourteen days after arriving at Pettis Island. test.
The study found that although they had been quarantined for four weeks beforehand, 16 of the recruits tested positive for Covid-19 within two days of arrival. The study said that another 24 recruits tested positive seven days after arriving at the base, and another 11 recruits tested positive on the 14th day. Only five participants reported any symptoms of Covid-19.
According to the study, another 26 recruits who did not participate in the study tested positive for the virus on the 14th day.
Harm van Bakel (Harm van Bakel), mountain geneticist. The Icahn School of Medicine in Sinai State sequenced the virus to better understand how the virus spreads among people. He discovered that although the Marine Corps implemented all public health measures, there were still six separate infection groups on the base.
He said: “If you don’t conduct frequent and extensive testing for such young people, it will be difficult to find all positive cases.” “Therefore, only relying on symptom screening, social distancing, and guidelines for wearing masks may still miss cases.”
Senior contributor Sealfon (Sealfon) said that their findings coincided with the National Basketball Association’s attempt to create a so-called bubble to end the season earlier this year. The NBA conducted daily Covid tests on all players and employees in the bubble and successfully stopped the virus.
Sealfon added that universities and universities should pay attention to their research results. He said that despite strict compliance with infection control protocols at Marine Corps bases, college students are less likely to engage in social distancing and wear masks, which makes frequent testing more important.
He said: “Public health measures are very important, but they are far from enough.” “This is a difficult virus. You can’t let your guard down.”
