New positive test from those who have already been infected with the coronavirus raises questions from employers. For example, the virus was re-detected in a Carinthian woman on Tuesday after she had been tested negative before and had become ill. Apparently an Austrian bass working in the health sector has already been tried three times.
As reported by the “Salzburger Nachrichten” (Wednesday edition), Lower Austria suffered from a crown disease with a mild course in mid-April. After 14 days of quarantine, the virus was re-detected in a test in early May.. He had to stay home, but not in strict quarantine. When he wanted to go back to work these days and had to take another test, he was positive for the third time. Now the man is sitting at home again.
According to the Ministry of Health, it is recommended that people working in the health or care sector, including outpatient facilities, be fired from work in the event of a positive crown test. In case of resumption, it must be fulfilled that a negative SARS-Cov-2-PCR test was obtained from two simultaneous swabs of the mouth and nasopharynx.
It is still unclear how contagious these people really are. Detecting the genetic material from SARS-CoV-2, even after several weeks, says nothing about whether someone is still infectious. In PCR virus genome tests, the genome components of the pathogen can be found in nasopharyngeal swabs for approximately 20 days, in extreme cases up to 37 days. Like the Viennese trip and tropical medicine Herwig Kollaritsch He told the APA, even after a positive test, it is not known if it is a live virus.
“All the data tells us that two days without symptoms of Covid disease 19, a person is no longer infectious,” said Kollaritsch. But it also had to be understandable that one had to be particularly careful with certain people, such as the health professions. “In addition to the risk of infection in hospitals, etc., this also implies liability problems,” explained the expert. Antibody tests would also not clarify the question. Colarctic: “All of these people have antibodies.“
Weeks ago, reports from Asia came to Corona patients who recovered from the hospital and tested positive for the virus a few days later. The well-known virologist from Berlin. Christian drosten von Berliner Charite emphasized that the pathogen might sometimes be detectable just at the end of the disease and not in the middle. “The virus has been around the whole time, but the test cannot always detect it.“he said on his podcast.
The virus has been around the whole time, but the test cannot always detect it.

Drosten illustrates this with goldfish in a children’s pool. Take a sample blindfolded with a bucket, be a gold fish in it, like a picture for a virus particle, and then don’t. At the end of the disease, the viral load is low, so there are fewer and fewer goldfish in the group by comparison. This increases the probability that a test will also be negative, even if there is still viral material in the patient. Therefore, experts do not assume a multi-phase course of corona disease.
