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.

Malian defence minister killed in attack that saw jihadis and rebels seize towns, military bases
Dakar (AP): Malian Minister of Defence Gen. Sadio Camara was killed in an attack as jihadi and rebel forces seized towns and military bases across the country, according to a military officer and two other sources on Sunday.
There was no immediate comment from the Malian government.
“Unfortunately, the Ministry of Defence, Gen. Sadio Camara, has been killed during the attack which targeted his house yesterday,” said a military official who spoke on condition of anonymity because he did not have permission to speak to the media.
Two other people, a civil society leader and a security member, confirmed the information.
Separatist fighters on Saturday joined Islamic militants in launching one of the biggest coordinated attacks on the Malian army in the capital and several other cities that left at least 16 wounded.
The separatists have been fighting for years to create an independent state in northern Mali, while al-Qaida and Islamic State group-aligned militants have been fighting the government for over a decade.
Malian troops and Russian mercenaries withdrew from the northern city of Kidal after the attacks, the rebels said Sunday.
A spokesperson for the Tuareg-led Azawad Liberation Front, or FLA, a separatist group, said the Russian Africa Corps troops and the Malian military withdrew from the city after an agreement was reached for their peaceful exit.
“Kidal is declared free,” said FLA spokesperson Mohamed El Maouloud Ramadan.
The Malian army did not respond to requests for comment but in an earlier statement said they were “tracking down terrorist armed groups in Kidal.”
The separatists have been fighting for years to create an independent state in northern Mali. Kidal had long served as a stronghold of the rebellion before being taken by Malian government forces and Russian mercenaries in 2023. Its capture marked a significant symbolic victory for the junta and its Russian allies.
It was the first time the separatists worked alongside the al-Qaida-linked militant group JNIM, which also claimed responsibility for Saturday's attacks on Bamako's international airport and four other cities, including Kidal, in central and northern Mali.
“This operation is being carried out in partnership with the JNIM, which is also committed to defending the people against the military regime in Bamako,” Ramadan said.
Wassim Nasr, a Sahel specialist and senior research fellow at the Soufan Center security think tank, said that the coordination between the two groups, as well as the explicit call for the Russian military to leave, is new.
“The coordination, conducting attacks all over the country at the same time, real coordination on the military level but also on the political level because both claims of both groups they acknowledged that they worked together, this is a first,” said Nasr.
Mali government spokesperson Gen. Issa Ousmane Coulibaly said on state television late Saturday that 16 people were wounded, including civilians and military personnel, and that several militants were killed. He did not provide a death toll.
The governor of Bamako's district, Abdoulaye Coulibaly, announced a three-day overnight curfew, from 9 p.m. to 6 a.m.
The Economic Community of West African States has condemned the attacks and called on “all states, security forces, regional mechanisms and populations of West Africa to unite and mobilize in a coordinated effort to combat this scourge.”
The separatists called on Russia to “reconsider its support for the military junta in Bamako, whose actions have contributed to the suffering of the civilian population.”
Following military coups, the juntas in Mali, Niger, and Burkina Faso turned from Western allies to Russia for help in combating Islamic militants. But the security situation has worsened in recent times, with a record number of attacks by militants. Government forces have also been accused of killing civilians they suspect of collaborating with militants.
In 2024, an al-Qaida-linked group claimed an attack on Bamako's airport and a military training camp in the capital, killing scores of people.
Ulf Laessing, head of the Sahel program at the Konrad Adenauer Foundation, said that while the attacks were a major blow to the credibility of Mali's Russian partners, JNIM is unlikely to take control of Bamako in the near term due to opposition from the local population.
“The attacks are a major blow to Russia as the mercenaries had no intelligence about the attacks and were unable to protect major cities. They have unnecessarily worsened the conflict by not distinguishing between civilians and combatants,” Laessing said.
