90% of recovered COVID-19 patients in Wuhan suffering from lung damage: report
Beijing: Ninety per cent of a sample group of coronavirus-recovered patients from a prominent hospital in China's Wuhan city where the pandemic broke out have reported lung damage and five per cent of them are again in quarantine after testing positive for the virus, according to a media report on Wednesday.
A team at the Zhongnan Hospital of Wuhan University led by Peng Zhiyong, director of the hospital's Intensive Care Unit, has been conducting follow-up visits with '100 recovered patients' since April.
The first phase of this one-year programme finished in July. The average age of the patients in the study is 59.
According to the first phase results, 90 per cent of the patients' lungs are still in a damaged state, which means their lungs ventilation and gas exchange functions have not recovered to the level of healthy people, state-run Global Times reported.
Peng's team conducted a six-minute walking test with the patients. They found that the recovered patients could only walk 400 metres in six minutes while their healthy peers could walk 500 metres in the same period.
Some recovered patients have to rely on oxygen machines even three months after being discharged from the hospital, Liang Tengxiao, a doctor from the Dongzhimen Hospital, Beijing University of Chinese Medicine, was quoted as saying by the report.
Liang's team is also conducting follow-up visits with recovered patients aged above 65.
The results also showed that antibodies against the novel coronavirus in 10 per cent of the 100 patients have disappeared.
Five per cent of them received negative results in COVID-19 nucleic acid tests but positive results in Immunoglobulin M (IgM) tests, and thus have to be quarantined again, the report said.
IgM is usually the first antibody produced by the immune system when a virus attacks. A positive result in an IgM test usually means that a person has just been infected by the virus.
It is still unclear if this means these people have been infected again.
The 100 patients' immune systems have not fully recovered as they showed a low level of B cells -- - a primary force for killing viruses in the human body -- but a high level of T cells which only recognise viral antigens outside infected cells.
"The results revealed that the patients' immune systems are still recovering," Peng said.
The patients also suffered depression and a sense of stigma. Most of the recovered patients told the team that their families were not willing to have dinner with them at the same table, the report said.
Less than half of the recovered patients have returned to work, it said.
The findings are significant as the coronavirus first emerged in Wuhan city.
Hubei province for which Wuhan is the provincial capital has reported a total of 68,138 confirmed COVID-19 cases till now. The disease has claimed 4,512 lives in the province, according to the official data.
China reported 27 new confirmed COVID-19 cases on Tuesday, including 22 locally-transmitted cases, the National Health Commission (NHC) said on Wednesday.
All locally-transmitted cases were reported in Xinjiang Uygur Autonomous Region, the NHC said.
On Tuesday, five new imported cases were also reported. Of the cases, two were reported in Shanghai and one each in Beijing, Sichuan and Shaanxi, the commission said.
As of Tuesday, the total number of confirmed COVID-19 cases had reached 84,491, including 810 patients who were still being treated, with 36 in severe condition.
Altogether 79,047 people had been discharged after recovery, and 4,634 had died of the disease in the mainland, the NHC said.

Zubeen Garg's drowning in Singapore highlights vessel operators' responsibility: legal experts
Singapore (PTI): The drowning of Indian singer-composer Zubeen Garg has brought the spotlight on rules and regulations that concern responsibilities of vessel operators when dealing with intoxicated passengers, according to a media report that cited legal experts.
A cultural icon in India’s northeastern region, 52-year-old Garg travelled to Singapore in September 2025 to perform at a live event. A day before his performance, he went on a yacht trip with a group of people. He drowned while swimming in the sea near Lazarus Island, which is a popular diving spot.
His death shook his home state Assam, where millions came out on the streets mourning. Later, police cases were registered against the organiser of the event, his manager and some others.
Nico Lee, managing director of the Triangle Legal law firm, told The Straits Times that Singapore has Maritime and Port Authority of Singapore (Port) Regulations under which there are provisions to debar drunk passengers.
The owner, agent or captain of the vessel must not allow persons under the influence of alcohol or drugs onboard if they are intoxicated to a point where they endanger safety of the vessel, its crew or any person in it.
“In terms of civil liability, it could be argued that a yacht captain is negligent, as he owes a prima facie duty of care to guests on board under general negligence principles,” Lee was quoted as saying by the newspaper.
The singer and his entourage of about 15 individuals were partying on a chartered vessel, which they had boarded at Marina at Keppel Bay.
A death certificate issued by the Singapore General Hospital listed his cause of death as drowning.
An autopsy report suggested that Garg had 333 mg of alcohol per 100 ml of blood in his system, which was four times the legal limit for driving in Singapore and is likely to have impacted his coordination.
Citing Garg’s case, Lee said the circumstances were serious, as the controller of the vessel knew that the guest was intoxicated. Also, he may not have understood or processed a safety briefing for all passengers.
“That combination makes reliance on an ordinary briefing inadequate. If intoxication reaches a level that endangers the safety of the vessel or persons on board, the person in charge should not permit boarding at all,” he said.
According to Lee, the vessel’s operators could also have assigned a crew member to directly supervise him or ensure that he received a one-to-one explanation when he was capable of understanding.
Part of the responsibility could be attributed to the guest if he chose to enter the water and ignore instructions or behave dangerously despite the yacht owner or charterer’s best efforts, Lee said.
Vanessa Sandhu from Clifford Law LLP told The Straits Times that a key question is whether the yacht captain or operator owed a “duty of care” to the passenger and, if so, whether a breach of that duty caused the death.
“A yacht captain and operator generally owe passengers a duty to take reasonable care for their safety while on board, including swimming or water activities. This may include providing safety equipment and issuing appropriate safety instructions,” the daily quoted Sandhu as saying.
“However, the standard of care is an objective one, based on what a reasonable captain or operator would have done in the circumstances. It is not an absolute obligation to prevent all harm,” she said.
During the coroner’s inquiry, the operators of the vessel had said that no one had forced the singer to consume alcohol or enter the water, and that the entire entourage was informed on the yacht about the necessity of wearing life jackets before going for a swim.
A coroner’s inquiry on March 25 ruled Garg’s death as accidental drowning. On April 1, the police said that investigations into the singer's death had concluded, with no evidence of foul play.
However, in Assam, where seven persons were arrested in connection with Garg’s case, and some of them charged with murder, the matter is being heard in the court. All the suspects have denied any wrongdoing.
