Covid can reinfect; deadlier the 2nd time

Even the recovered still have virus

Ontario's first two cases of the new coronavirus
— a husband and wife — have recovered but remain in isolation at their home because tests still show them carrying the bug, authorities say.
Nose and throat swabs taken since the man was released from Sunnybrook hospital two weeks ago continue to show traces of coronavirus in both him and his wife, who was never hospitalized.

Public health officials are trying to decipher what that indicates as scientists in China and around the world work to pinpoint more traits of the virus, which has never before been seen in humans.

“There is some genetic material or viral material left in the individual specimens,” Dr. Vanessa Allen of Public Health Ontario said Thursday.

“We don’t know that means, whether that’s live or dead virus,” Allen said. “There’s some component of virus in those specimens and the criteria that have been laid out are being followed, that we required two negative specimens until we understand more about what that means.Those tests must be taken at least 24 hours apart.

Ontario’s chief medical officer of health said the apparent stubbornness of the coronavirus in the Toronto-area couple, who returned from China Jan. 22 aboard a China Southern Airlines flight, may be due to their age.

The man is in his 50s and has some other health conditions that could impair his ability to shed the virus, Dr. David Williams told a news conference at Queen’s Park.

Very concerning, between the varying incubation periods reported in the article, as well as multiple false negative tests. Very concerning.
