COVID-19: Recovered patients have partially reduced lung function

More than 86,000 people worldwide have now recovered from the lung disease COVID-19. In their case, the infection manifested itself in mild or moderate form, or it’s because these patients received excellent medicalcare, reports DW newsletter.
This number can provide solace, on the one hand, but on the other there is still little information about how these people are doing after the infection has run its course.
With great relief and joy, some convalescents describe how they have survived the physical, but above all psychological stress: the healing of symptoms, the agonizing uncertainty, and the gruelling isolation phase. They are happy to be immune to SARS-CoV-2 after having survived the illness. Relief is often mixed with apprehension – for instance, with regard to the many people who have not yet infected.

Complete recovery?
As the new coronavirus generally affects the lower respiratory tract, most of those infected exhibit a dry cough, shortness of breath or pneumonia.

Recovered coronavirus patients can be left with damaged lungs, researchers in Hong Kong have claimed.
A small study of 12 patients discharged from hospital showed that two or three had reduced lung function. However, it is too early to confirm any long term effects.
“In some patients, lung function could decline by about 20 to 30 percent after recovery,” says Dr. Owen Tsang Tak-yin, medical director of the Infectious Diseases Centre at Princess Margaret Hospital in Hong Kong. “They wheeze when they go a little faster”.
Computer tomography have shown fluid or debris-filled sacs in the lungs, which may get progressively worse as the illness develops.
The findings from Hong Kong confirm very early investigations from Wuhan in early February 2020. In a recent study, scientists from Zhongnam Hospital of Wuhan University analyzed 140 lung scans of COVID-19 patients and found a ground glass opacity in both lungs of each patient.
Suspected pulmonary fibrosis
Further investigations of the recovered COVID-19 patients must now be conducted to show whether they have developed pulmonary fibrosis. Pulmonary fibrosis (PF) means scarring in the lungs. Over time, the scar tissue can destroy the normal lung and make it hard for oxygen to get into your blood. Low oxygen levels (and the stiff scar tissue itself) can cause short of breath, particularly, during physical exertion.

Early detected, a pulmonary fibrosis can be stopped
Lung fibrosis cannot be cured because the scarred changes in the lung tissue do not regress. But the progression of pulmonary fibrosis can be delayed and sometimes even stopped if detected in time.

re recovered COVID-19 patients immune?
The majority of virologists are convinced that recovered COVID-19 patients are immune to the new SARS-CoV-2 virus after the infection has run its course. After all, the body’s own immune system has produced precisely those antibodies during the infection that render the pathogen harmless.
This all-clear also applies to those who had only a weak course of the disease showed only few or perhaps no symptoms. Nevertheless, their immune system reacted to the pathogen and produced the corresponding antibodies. A renewed infection with the new coronavirus is therefore highly unlikely.

Earlier, he had bagged a Bachelor degree from the same university in 1984, after which he proceeded to the Nigerian Institute of Journalism, Lagos, in 1990, for a postgraduate diploma in Journalism. He had done many courses in communication, including the EU-BBC Editing Course in 2002. Mr. Fashomi combines effectively the practice, research and teaching of communication. And to date, he has published two academic works in communication: Issues in Communication Technology and Policy (2010) and Economic and Social Issues in Advertising and PR (2013). He had his first break in the Nigerian media in Concord Newspapers in 1990 and today, he has over two and half decades experience earned in several newspapers. He has been part of many start-ups, such as The Republic (1987), The Comet (1999), The Anchor 2001 - 2002; Sun Newspapers (2003); Westerner newsmagazine (2005 - 2010) as Editor; National Life (2011) as Sunday Editor, and Newswatch Newspapers (2012- 2016) as Daily Editor. Dele Fashomi is now the Publisher/Editor-in-Chief of newspaper online, which he started in July 2015. He is also into biography writing, with many books in his trail, some of which he wrote alone and one he co- authored with his mentor, Mr Dare Babarinsa, entitled:  Olabiyi Durojaiye - DARE TO BE DiFFERENT. He also guided and collaborated with Pa Olatunji Odusanya in writing his autobiography - AGAINST ALL ODDS. There are many other books in the works under his pen.
