Yesterday, Friday, the Ministry of Health and Population in Egypt announced that 29 new cases were infected with Corona virus, with 60 cases whose results turned from positive to negative and 39 cases of similar recovery and discharged from hospitals. What does it mean to shift the result of cases from positive to negative and does it mean to recover from the virus completely or not? What is the difference between it and those recovering from the virus? This is what we learn about in the following lines.
Male website “medlineplus“The positive result of corona virus analysis means that you have a corona virus infection, but if your results are negative, and with symptoms similar to” corona “you may need more tests in order to get a diagnosis, you will still need to take steps to prevent the spread of infection.
According to a video posted by “CNNOn his official Twitter page, Dr. Deborah Brix, an American physician and coordinator of the team tasked with following up on Corona virus developments, warned against the wrong interpretation of the negative results of virus tests.
White House coronavirus response coordinator Dr. Deborah Birx said that even if a person has a negative coronavirus test, “that means you’re negative that day” and they shouldn’t say up on taking precautions to prevent infection. https://t.co/XQUu2uxgCh pic.twitter.com/QewsM7vzNP

She explained in a press conference that “when you get negative results, this means that the results are negative on that day, this does not mean that the virus does not spread during the night, but the results may become positive the next day.”
This means that shifting results from positive to negative does not mean a complete recovery from the virus.
“When you have negative results, this does not mean stopping taking precautions. Rather, the person who has symptoms of the disease must take all precautions to not transmit infection to others because diseases of the respiratory system are infectious, even if the results of the analysis are negative.”
This means that shifting the results from positive to negative means the beginning of the recovery of the person with the virus and not his final recovery, so it must be put under test and under consideration to complete recovery and not spread the infection, where the analysis is performed again after another time period of 48 hours.
According to “BBC“Corona virus analysis works by searching for the genetic code of the virus, where a sample is taken from the patient, then, in the laboratory, the genetic code of the virus is extracted (if present) and copied repeatedly, making small quantities vast and discoverable.
Usually the tests are “RT-PCR“, Widely used in medicine to diagnose viruses such as HIV and influenza, is very reliable.
A study published in the journal “Radiology” showed that five of the 167 patients had negative results, although lung tests showed that they were sick. Then they showed positive results to the virus later.
The site pointed out that the results of the analysis may change due to many factors, including that patients have the coronavirus, but in such an early stage, there is not enough to detect it.
There may also be a problem with the way the tests are performed, and if the samples are not stored and processed properly, the test may not work.
There has also been some discussion about whether doctors who are testing the back of the throat are looking in the wrong place – this is a deep lung infection and not a nose and throat infection.
During the analysis, scientists try to choose a region of the virus code that they believe will not mutate, but if there is a weak match between it and the virus in the patient, the affected patient may get a negative result.
Likewise, the virus code may remain in the analysis with a weak concentration that is not shown in the analysis Pcr On the first examination.
So people should be tested again if their symptoms persist even though the results are negative.
