Posted April 12, 2020 2:02 pm
GENEVA —The World Health Organization (WHO) said on Saturday that it was looking into reports of some COVID-19 patients testing positive again after initially testing negative for the disease while being considered for discharge.


South Korean officials on Friday reported 91 patients thought cleared of the new coronavirus had tested positive again. Jeong Eun-kyeong, director of the Korea Centers for Disease Control and Prevention, told a briefing that the virus may have been “reactivated” rather than the patients being re-infected.
The Geneva-based WHO, asked about the report from Seoul, told Reuters in a brief statement: “We are aware of these reports of individuals who have tested negative for COVID-19 using PCR (polymerase chain reaction) testing and then after some days testing positive again.

“We are closely liaising with our clinical experts and working hard to get more information on those individual cases. It is important to make sure that when samples are collected for testing on suspected patients, procedures are followed properly,” it said.... https://globalnews.ca/news/6809875/w...test-recovery/

SEOUL, March 31 (Yonhap) -- A Navy sailor has tested positive again for the new coronavirus after having fully recovered from the disease, the defense ministry said Tuesday.

The sailor stationed on the southern island of Jeju was released from a hospital last week after recovering fully from the COVID-19 virus following monthlong treatment.

But he redeveloped symptoms while in preventive quarantine, and tested positive again Tuesday, officials said, adding that he was immediately sent to a hospital.

SOUTH KOREA SEES RISE IN 'REACTIVATED' CORONAVIRUS PATIENTS WHO WERE INITIALLY CURED OF VIRUS

BY JASON LEMON ON 4/13/20 AT 9:07 AM EDT
After a person is infected with a virus and recovers, they generally develop a level of immunity. Because of this, scientists can train people's immune systems to recognize and fight off diseases by infecting them with an antigen so they can develop immunity to it....

If people do not develop immunity after being infected by the coronavirus, as some scientists fear may be the case, that would make it more difficult to develop a vaccine. However, the health experts in South Korea currently believe it is more like that faulty tests and reactivation are more plausible explanations.

WHO Officials: Unclear If Recovered Coronavirus Patients Are Immune to 2nd Infection

World Health Organization officials said not all people who recover from the coronavirus have the antibodies to fight a second infection. This raises concerns that patients don’t develop immunity after surviving COVID-19

By William Feuer, Berkeley Lovelace Jr. | CNBC • Published 4 hours ago • Updated 4 hours ago

World Health Organization officials said Monday not all people who recover from the coronavirus have the antibodies to fight a second infection, raising concern that patients may not develop immunity after surviving COVID-19.

“With regards to recovery and then re-infection, I believe we do not have the answers to that. That is an unknown,” Dr. Mike Ryan, executive director of WHO’s emergencies program, said at a press conference at the organization’s Geneva headquarters on Monday.

....A preliminary study of patients in Shanghai found that some patients had “no detectable antibody response” while others had a very high response, said Dr. Maria Van Kerkhove, WHO’s lead scientist on COVID-19. Whether the patients who had a strong antibody response were immune to a second infection is “a separate question,” she added.

More than 300,000 of the 1.87 million coronavirus cases across the world have recovered, WHO officials noted, adding that they need more data from recovered patients to understand their antibody response, whether that gives them immunity and for how long......

“There are many reasons why we might see reactivation of infection either with the same infection or another infectious agent,” he said. In general, “there are many situations in viral infection where someone doesn’t clear the virus entirely from their system.” Some patients can also clear the main infection but develop a secondary bacterial infection, he said.... https://www.necn.com/news/coronaviru...ction/2259410/

Covid-19 special: Discharged British man tests positive again
By Huu Cong, Manh Tung April 14, 2020 | 08:37 am GMT+7

In an unusual development, “Patient 22,” a British man discharged from Da Nang March 27 has tested positive again, putting HCMC on guard.

He had come into contact with dozens of people in HCMC before leaving the country, local officials said.

Authorities learnt of this special case Sunday evening, Nguyen Tan Binh, Director of HCMC Health Department said at a Monday afternoon meeting.

He said that the Covid-19 illness might have recurred within the patient or he might have got infected again after he was discharged from the hospital in Da Nang.

"From now on, visitors to Ho Chi Minh City must be closely monitored," Binh said.

Reports had said that female "Patient 50," a 24-year-old Vietnamese woman being treated in the northern Quang Ninh Province, and "Patient 91," a 43-year-old British man in HCMC, had also tested positive after negative results and they are still undergoing treatment.

Meanwhile, a Reuters report Monday said at least 116 people initially cleared of the novel coronavirus had tested positive again in South Korea.

The report quoted Jeong Eun-kyeong, director of the Korea Centers for Disease Control and Prevention (KCDC), as saying the virus may have been reactivated rather than the patients being re-infected.

It also cited other experts’ opinions that "faulty tests may be playing a role, or remnants of the virus may still be in patients’ systems but not be infectious or of danger to the host or others."

Post discharge movements

The 66-year-old British man had flown into Hanoi from London on the Vietnam Airlines flight VN54 on March 2.

The British man was tracked down by local authorities as he toured the country. He tested positive on March 8 and was treated at Da Nang Hospital until he was discharged on March 27 after testing negative t... https://e.vnexpress.net/news/news/co...n-4084216.html

The British man had been hospitalised in Danang City in Vietnam but after being declared healthy and free of coronavirus he headed for a flight home from Tan Son Nhat Airport


...They said that the 60-year-old man, who was not named, had been admitted to hospital on March 8 and released on the March 27 after testing negative three times.

After that, he had been quarantined for another two weeks at a hotel in Danang City in line with guidelines issued by the Health Ministry.

He had then flown to Ho Chi Minh City at the end of last week and was tested while staying at an airport hotel while waiting for the next flight.

He had actually boarded the flight when the city's Centre for Diseases Control revealed that the man had tested positive for the Covid-19 virus....At the heart of the outbreak in February, China had also confirmed cases where people who appeared to have recovered and tested negative were later found to have tested positive, confounding the popular belief that those who survive would be immune at least in the immediate future from catching the disease again.

It is reportedly the first time it has happened in Vietnam.....

The family of a "devoted dad" who died after appearing to have recovered from Covid-19 have described how he suffered a sudden relapse before he died as he was being rushed to hospital.

Dom Merrix suffered a heart attack after he had a rapid decline in his health which left him struggling to breathe at his home in Portsmouth, Hampshire.
The 48-year-old had been in self-isolation for 16 days after he began to suffer the symptoms of the coronavirus although he was not tested for it.

Family friend Rachel Hibbert said: "He got up as normal and wanted to have a shower.

"He sounded absolutely fine.

"Then bang out of nowhere it happened.

"He texted his daughter to open the windows because he was struggling to breathe.

"He then texted Sarah begging for help.

"Sarah came downstairs and found him on his hands and knees struggling to breathe.

"When the paramedics arrived they put him on the trolley and asked him to lean back but he couldn't do it.
"That was it. Then the doors to the ambulance shut. They didn't see him alive again.

"His heart stopped and the paramedics spent 20 minutes outside the house trying to get it started again.

"By the time he got to hospital they couldn't bring him back."

Japan confirms first case of person reinfected with coronavirus

The reinfection has health officials worried the illness could stay dormant after signs of recovery.

By
Joseph Guzman Story at a glance

• Officials in Osaka say a tour bus guide tested positive for COVID-19 for a second time.
• There have been a number of cases of reinfection in China.
• Japan’s prime minister has asked schools to close in an effort to curb the outbreak.

Japan is reporting its first case of a person becoming reinfected with the coronavirus after showing signs they had fully recovered, according to Reuters.

Osaka’s prefectural government confirmed Wednesday a woman working as a tour bus guide tested positive for coronavirus for the second time after developing a sore throat and chest pain. The woman, who is said to be in her 40s, first tested positive in late January and was discharged from the hospital on Feb. 1 after showing signs of recovery.

Reuters reports Health Minister Katsunobu Kato said the government would need to monitor the condition of others who were infected and later discharged as health experts investigate testing positive for COVID-19 after an initial recovery.

As much remains unknown about the virus, cases of reinfection have health experts worried that the illness could remain dormant after an apparent recovery.

A total of 141 people who had apparently recovered from Covid-19 have tested positive again, South Korea's Centers for Disease Control and Prevention (KCDC) said on Thursday.


Most experts think it's unlikely that somebody will be re-infected for the coronavirus soon after recovering. It's possible that issues with testing – or varying amounts of viral RNA in the body, which the tests look for – could explain why people tested positive after testing negative....

South Korean health officials are investigating several possible explanations for a small but growing number of recovered coronavirus patients who later test positive for the virus again.

Among the main possibilities are re-infection, a relapse, or inconsistent tests, experts say.

South Korea had reported 141 such cases as of Thursday, according to the Korea Centers for Disease Control and Prevention (KCDC).

What S. Korea knows so far about recurring COVID-19 cases

By Ock Hyun-ju
Published : Apr 17, 2020 - 17:24 Updated : Apr 17, 2020 - 17:33

A total of 163 patients previously declared cured of COVID-19 have tested positive again in South Korea as of Friday, up 22 from a day earlier, giving the government a fresh headache in its fight against the virus.

The recurring cases account for 2.1 percent of the 7,829 people released from quarantine after recovering. Studies are underway to find out why, according to the Korea Centers for Disease Control and Prevention.

It took 13.5 days on average for these patients to test positive again after being deemed clear of COVID-19 -- as little as one day and as long as 35.
...

An epidemiological and clinical analysis of 137 recurring cases showed that more than half of them, 72 people, had no symptoms and 61 people showed mild symptoms, according to the KCDC. Analysis is underway for the other four.

Those who test positive again after release from quarantine are usually detected through regular testing required by some municipalities or when they show symptoms and seek testing themselves.

Health officials here have cautiously dismissed the possibility of patients being reinfected with the virus.

....

“We could not find the virus that was alive (in recovered patients who tested positive again), so we think it will not be highly infectious,” KCDC Director General Jeong Eun-kyeong said at a briefing Friday.

“In the cases testing positive again within one week after full recovery, many of them produce negative and positive results alternately before eventually producing positive results due to remaining pieces of the virus in the body,” she said.

As of Friday, there were no cases of secondary transmission from recovered patients who had tested positive again, according to the KCDC.
Some 294 people came into contact with the patients who tested positive again, with 256 of them under government monitoring.

While 22 recovered patients were back in self-quarantine after testing positive again on Friday, Korea saw 22 new infections. The total number of COVID-19 cases here stands at 10,635.

The number of recurring cases has more than tripled from 51 on April 6, keeping the authorities on their toes despite the country largely having brought the virus situation under control, with fewer than 30 new cases per day for the past week.

There were no such recurring cases of severe acute respiratory syndrome or Middle East respiratory syndrome, the authorities said a day earlier, calling the novel coronavirus “evil.”...:tiphat:http://www.koreaherald.com/view.php?ud=20200417000631

COVID-19 In South Korea Appears To Have 'Reactivated' In Some Patients

By Cathy Burke | Friday, 17 April 2020 10:03 PM

More than 160 South Koreans have tested positive a second time for the coronavirus, suggesting COVID-19 may have a longer shelf life than expected, the Wall Street Journal reported.

The virus has “reactivated” in the patients, meaning it went dormant and came back,...But the research remains ongoing and inconclusive, the Journal reported.

...
“It may be that you have to test these recovered people every month for symptoms or viruses,” Mary Guinan, a former chief scientific adviser to the U.S. Centers for Disease Control and Prevention director, told the Journal. “Maybe it comes and goes. We don’t know.”

The World Health Organization has acknowledged not all recovered patients appear to have the antibodies to stave off a second infection, the Journal reported.

“Countries in Europe and the U.S. will see the same phenomena after us, and they will look to South Korea’s ongoing research for clues,” Lee Hyuk-min, an infectious-disease doctor in Seoul, who advises the government on COVID-19 response, told the Journal...:tiphat:https://www.newsmax.com/world/global.../17/id/963490/

Chimps 're-challenged' with virus after recovery shows role of immunity

Published: April 18, 2020 14:18Jay Hilotin, ASsistant Editor

....Now, however, there had been concerns raised over reported COVID-19 “reinfections”. On February 28, 2020, Reuters reported that a number of discharged patients in China and elsewhere are testing positive after "recovering".
....
Here’s a lowdown on the reported reinfection story:

Q: What triggered such reinfection concerns?


Following unspecified reports of "reinfection", on April 11, 2020 (Saturday), the World Health Organization (WHO) said that it was looking into reports of some COVID-19 patients testing positive again — after initially testing negative for the disease while being considered for discharge.
Q: What’s prompted reports of “reinfection”?



Beside the February reports in China, on April 10 (Friday), South Korean officials also reported 91 patients thought cleared of COVID-19 had “tested positive again”. Korean health officials said, however, that they are trying to find out if this is the case.
Q: What accounts for the supposed “reinfections”, as in the 91 reported cases in South Korea?


Experts said it’s possible it was a relapse, instead of a reinfection, as some SARS-CoV-2 tests are not rigorous enough, that they could yield “false negative” results for the virus.

The discovery of immunity in monkeys 28 days following the primary infection sheds some light on puzzling cases in which patients appeared to relapse, or be re-infected. Some discharged after testing negative for coronavirus later again developed symptoms, even testing positive.
