It is said that almost a hundred people in South Korea tested positive again for the coronavirus after recovery. So far, most scientists suspect that recovered patients are immune.

WHO examines Covid 19 relapses

The World Health Organization (WHO) investigates suspected relapses of Covid 19 patients who were considered cured after negative virus tests. "We are in close contact with our clinical experts and are working hard to get more information about these individual cases," a WHO position told Reuters about the unusual cases in South Korea. It is very important that the prescribed procedure is followed when assessing the patients. According to the WHO guidelines, a patient can only be discharged from the hospital if two coronavirus tests are negative every 24 hours.

Anyone near Trump or Pence will be given rapid coronavirus test - White House

  Anyone near Trump or Pence will be given rapid coronavirus test - White House With the coronavirus contagion spreading, the White House said on Friday that anyone expected to be near President Donald Trump or Vice President Mike Pence will be given a rapid COVID-19 test. “As the physician to the president and White House Operations continue to protect the health and safety of the president and vice president, starting today anyone who is expected to be in close proximity to either of them will be administered a COVID-19 test to evaluate for pre-symptomatic or asymptomatic carriers status to limit inadvertent transmission," said White House spokesman Judd Deere.

In South Korea, almost a hundred people recovering from an infection have been tested again positively for the novel corona virus, according to local authorities. The director of the Korean Center for Disease Control, Joeng Eun Kyeong, said on Friday that the virus was more likely to have been "reactivated" than that it was a new infection. South Korean health officials said it is still unclear what is behind this trend. Epidemiological investigations are currently ongoing.

The question of whether people recovering from an infection can catch the coronavirus again is of international importance. Many countries believe that people cured of a corona infection develop immunity to the virus and that over time a large enough population will be immune to the disease to prevent the pandemic from flaring up again.

So far, there is also a lot of evidence, for example a Chinese study on rhesus monkeys, which showed no signs of disease after a second infection. In the past, alleged new infections mostly turned out to be incorrect tests. The detection of the virus by means of PCR repeatedly incorrectly produces negative results, says corona expert Christian Drosten from the Berlin Charité.
