Two tests help predict Covid-19 proliferation | World News
Only by implementing a carefully controlled program that uses two very different things Covid-19 test kit Researchers have shown that it is possible to predict how the disease will affect the country.
Scientists emphasized the need to understand as quickly as possible when and where new cases of infection emerge. At the same time, it was imperative to identify already infected individuals, possibly non-infected, so that scientists could understand the behavior of the disease in the coming months. You can achieve these individual goals with two different tests.
To find the first, or newly infected, one, medical staff must use the polymerase chain reaction (PCR) test, which can find human virions. This test identifies a specific coronavirus gene sequence and creates multiple copies that are easily detected.
To identify people who are already infected and should now be immunized from a re-infection, doctors should use tests that show antibodies produced in response a Past infections of Covid-19
The University of Bath’s Andrew Preston said that the PCR test itself is very effective at detecting the virus, but its effectiveness depends on how well healthcare workers can take samples from patients, from the nose and back of the throat. Said to depend.
“If the virus is not picked up with a swab, the result is negative. Therefore, how effectively the swab is collected and how much virus is present at the sampling location can be used to determine if the virus is detected in infected individuals. Will decide whether to do that, “he said.
More testing will be done after Michael Gove’s announcement British health workers Tested Start with emergency medical doctors and nurses this weekend. However, there is a shortage of PCR machines, staff trained to use them, and most worried, the reagents needed to run them. It limits test acceptance.
As the disease continues to grow this year, PCR tests will be used, but antibody tests will be introduced in the coming months. The government has announced that it will purchase 3.5 million of these tests. These tests are currently being evaluated at Oxford University.
“Testing people around the country to see if they are infected with Covid-19 will give an accurate picture of the disease,” said Adam Finn, a professor at the University of Bristol. “This gives us confidence in our position and the steps we need to take to limit the spread of the virus. We are currently in the dark. It should stop. “
