Like various other respiratory illnesses, COVID-19 can cause lasting lung damage. Together we proceed to learn around COVID-19, we’re understanding an ext regarding exactly how it affect the lungs during acute illness and also afterward.

You are watching: How many people are recovering from coronavirus

Panagis Galiatsatos, M.D., M.H.S., is an professional on lung disease atJohns Hopkins Bayview clinical Centerand watch patients with COVID-19. He describes some the the short- and long-term lung problems lugged on by the brand-new coronavirus.

What walk COVID do to lungs?

COVID-19 can reason lung complications together aspneumoniaand, in the most severe cases, acute respiratory tract distress syndrome, or ARDS. Sepsis, another feasible complication of COVID-19, can likewise cause lasting injury to the lungs and other organs.

“As we have actually learned an ext about SARS-CoV-2 and also resulting COVID-19, we have discovered that in serious COVID-19, a significant pro-inflammatory problem can result in several vital diseases, complications and also syndromes,” Galiatsatos says.

COVID-19 Pneumonia

In pneumonia, the lungs come to be filled through fluid and also inflamed, leading to breathing difficulties. For part people, breathing difficulties can become severe enough to call for treatment at the hospital through oxygen or even a ventilator.

The pneumonia the COVID-19 reasons tends come take hold in both lungs. Air bag in the lung fill through fluid, limiting their capability to take in oxygen and also causing shortness that breath, cough and also other symptoms.

While most civilization recover indigenous pneumonia without any type of lasting lung damage, the pneumonia linked with COVID-19 have the right to be severe. Even after the an illness has passed, lung injury may an outcome in breathing difficulties that might take month to improve.

Acute respiratory Distress Syndrome (ARDS)

As COVID-19 pneumonia progresses, an ext of the waiting sacs come to be filled with liquid leaking native the small blood vessels in the lungs. Eventually, shortness that breath sets in, and also can cause acute respiratory distress syndrome (ARDS), a type of lung failure. Patients with ARDS are often unable to breath on your own and may call for ventilator support to help circulate oxygen in the body.

Whether it occurs at house or at the hospital, ARDS can be fatal. Human being who endure ARDS and recover from COVID-19 may have actually lasting pulmonary scarring.


Another feasible complication that a severe situation of COVID-19 issepsis. Sepsis occurs once an infection reaches, and also spreads through, the bloodstream, resulting in tissue damage everywhere it goes.

“Lungs, heart and other human body systems work-related together like tools in an orchestra,” Galiatsatos says. “In sepsis, the cooperation in between the organs falls apart. Whole organ systems deserve to start come shut down, one ~ another, consisting of the lungs and also heart.”

Sepsis, also when survived, have the right to leave a patient through lasting damage to the lungs and other organs.


Galiatsatos notes that when a person has actually COVID-19, the immune device is working hard to hit the invader. This have the right to leave the body more vulnerable to epidemic with another bacterium or virus on peak of the COVID-19 — a superinfection. More infection can an outcome in extr lung damage.

Three components in Coronavirus Lung Damage

Galiatsatos note three factors that influence the lung damages risk in COVID-19 infections and also how likely the human is come recover and also regain lung function:

Disease severity.“The an initial is the severity of the coronavirus epidemic itself — even if it is the person has actually a gentle case, or a major one,” Galiatsatos says. Milder situations are much less likely to reason lasting scars in the lung tissue.

Health conditions.Galiatsatos says, “The 2nd is whether there are existing wellness problems, such together chronic obstructive pulmonary disease (COPD) or heart disease that can raise the danger for severe disease.” Older world are also more vulnerable for a severe situation of COVID-19. Your lung tissues might be much less elastic, and also they may have weakened immunity because of progressed age.

Treatment.“Treatment is the third factor,” the says. “A patient’s recovery and long-term lung health is going to rely on what kind of care they get, and how quickly.” Timely support in the hospital because that severely okay patients deserve to minimize lung damage.

Can coronavirus patient lessen the opportunity of lung damage?

There room things patients have the right to do to rise their possibilities for much less severe lung damage, Galiatsatos says.

“If you have actually a health issue that puts girlfriend at higher risk, make certain you’re doing whatever you have the right to to minimization the possibility of contracting the virus. Also, make certain that your chronic health problems are managed and also they have the right to be. Because that example, people living with diabetes, COPD or heart disease should be especially careful to control those conditions with monitoring and also taking their medications as directed.”

Galiatsatos adds that proper nutrition and hydration have the right to also assist patients stop complications that COVID-19. “Staying fine fed is crucial for overall health. Appropriate hydration maintains ideal blood volume and healthy mucous membranes in the respiratory tract system, i m sorry can assist them far better resist infection and tissue damage.”

Coronavirus: Smoking, Vaping, Wildfire Smoke and also Air pollution

our expert,Panagis Galiatsatos, M.D., M.H.S. Discusses how smoking, vaping and also air pollution can increase the severity of COVID-19. Learn about how every of these could influence a COVID-19 diagnosis.

Is COVID-19 lung damages reversible?

After a serious situation of COVID-19, a patient’s lungs can recover, however not overnight. “Recovery from lung damages takes time,” Galiatsatos says. “There’s the early injury to the lungs, adhered to by scarring. Over time, the tissue heals, but it deserve to take three months to a year or much more for a who lung role to go back to pre-COVID-19 levels.

“Lung healing in of chin can develop symptoms,” Galiatsatos says. “It is comparable to a foot bone breaking, needing a cast for months, and having the cast come off. Nobody would suppose to begin to run appropriate away with the newly-healed leg bone. As the foot strengthens and muscle re-grows, patients will experience discomfort from this healing. This is what ours lungs walk through, too!”

He notes the doctors and patients alike need to be all set for proceeding treatment and also therapy.

“Once the pandemic is over, there will certainly be a group of patients with new health needs: the survivors. Doctors, respiratory tract therapists and other health care providers will need to aid these patients recuperate their lung function as much as possible.”
