Every week, if nearly half of the population is tested with the Kovid-19 by rapid antigen method, the epidemic may be eliminated in just a few weeks, even if it is tested with a less reliable rapid antigen kit than RT-PCR. Ho. This claim has been made in a new study.
Research published in the Journal of Science Advance has underlined that such a strategy would require keeping few people at home and not closing restaurants, bars, markets and schools.
Scientists from various institutions, including the University of Colorado, Boulder, US, who are involved in this research, said that the sensitivity of the kit used for the Kovid-19 probe at this time is quite varied.
He said that antigen detection for detection of infection required 1,000 times more virus presence than RT-PCR test. The study said that another test RT-lamp should also have 100 times more virus presence than the RT-PCR probe.
Scientists said that by now the standard RT-PCR test should contain the genetic element RNA of 5,000 to 10,000 per virus in a millimeter sample to detect infection. This means that this method shows the transition either in the initial phase or in the final phase.
“The big picture of our study is that when it comes to public health, it is better to have less sensitive results that are tested today rather than results,” said Daniel Larmore, working at the University of Colorado and lead author of the research paper. More sensitive delays should be investigated.
He said, “Instead of advising all people to stay in the house, you should make sure that a person who is infected does not spread the infection, we should only order the infected people to stay in the house so that the rest of the people are out of their lives. Could live
In this study, scientists assessed whether the sensitivity of the probe, the time it takes to repeatedly test and complete the procedure are most important in controlling Kovid-19.
Scientists analyzed available literature about the fluctuations in the number of viruses in the body during infection. They studied when people felt symptoms of infection and when they could spread the infection to others.
The researchers predicted the impact of the investigation in three possible situations with the help of a mathematics-based model. A city with a population of 10 thousand in the first position, a population of 20 thousand at the university level in the second position and a population of 84 lakh in the third position.
They found in the study that when it comes to controlling infection, the time taken for repeated investigation and testing becomes more important than the sensitivity of the test. Giving examples, scientists said that if large-scale but less sensitive rapid antigen testing is conducted twice a week in a large city, the spread of the virus can be reduced by up to 80 percent.
He said that if the same test is done twice a week by RT-PCR which results in 48 hours to arrive, the infection can be prevented by only 58 percent. Scientists said that the reason is that about two-thirds of the infected do not have any symptoms and they wait for the results and spread the infection during this time.
