Do people who recover from the corona virus recover completely?

Worldwide, the number of people infected with the new novel Corona virus has risen to nearly 4 million and more than 1.346 million have been cured.

But there is still a lot of uncertainty, meaning it is not clear how the disease can affect you on a long-term basis or how long you can be protected from it once you are sick.

It may take a long time to find out because scientists are still working on it and the epidemic is not over yet.

However, what has come to light so far is as follows.

Statistics of healthy people
Although more than 1.3 million people worldwide have beaten Code 19, the actual number could be higher, as most countries and regions do not disclose how many sick people have been recovered.

Douglas Donovan, a spokesman for Johns Hopkins University, told CNN: "Record cases outside of China are estimated at the national level based on local media reports and may be more than the actual number."

In some countries, due to limited testing capacity, many cases are not diagnosed and patients with minor or asymptomatic recovery are recovered without it, meaning that such individuals are not part of the overall or recovery case statistics.

Dr. Bala Hota, associate chief medical officer and professor of epidemiology at Rush University Medical Center in Chicago, told CNN: "Knowing the exact number of infected people in a population is a model for the rise and fall of the disease. It can be very helpful for people to know when they can return to work.

How is the recovery?
Recovery does not mean that the condition has completely healed. According to Dr. Bala Hota, many patients may experience mild cough and fatigue, even though they have been declared healthy and are not spreading the virus. It takes a long time to get to.

Mike Ryan, the World Health Organization's executive director, said in March that "it can take up to six weeks for the disease to recover, and many more can take months to recover."

This process can be different for people who need a ventilator.

Speaking to US News & World Report, Dr. J. Randall Curtis, a professor at the University of Washington's Harbor View Medical Center, said: "We've seen that patients who need ventilators have to stay for weeks at a time. Yes, and when they come out of the ventilator, they have to spend several days in the ICU and then stay in the normal unit of the hospital for several days or weeks to regain their strength.

According to a report, people who are on ventilators suffer physical and psychological damage on a long-term basis and if they have ARDS, a disease that causes difficulty in breathing, they can scratch the lung tissues. May also fall.

Long term effect
Dr. Shu Yuan Xiao, a professor at the University of Chicago School of Medicine, told ABC News that most moderate patients with code 19 are unlikely to have long-term effects after recovery, but the future of those who become more ill is not much better. ۔

In mid-March, medical experts in Hawking Kong discovered that people recovering from the new novel corona virus could have weakened lungs and some people could have shortness of breath when walking fast.

According to the South China Morning Post, the Hong Kong Hospital Authority came to this conclusion after examining the initial patients recovering from coronavirus disease code 19.

Doctors found changes in the lung capacity of 2 to 3 out of 12 patients.

Dr. Owen Tsang Tak Yin, medical director of the hospital's Infectious Diseases Center, told a news conference: "These people have shortness of breath when they walk a little faster, while some patients have 20 to 30 lung functions after complete recovery. The percentage may decrease.

He added that it was too early to determine the long-term effects of the disease, but a scan of the lungs of nine patients revealed a dust-like pattern on the glass, indicating organ damage.

But as noted above, the virus first appeared in December, so there is still a long way to go in terms of recovering patients.

But experts believe that the effects of severe pneumonia remain on the body, meaning that lung tissue can also be damaged if respiratory tract ARDS occurs.

Dr. Amish Adalja, an epidemiologist at the Johns Hopkins Center for Health Security, told ABC News: "It's common for any type of pneumonia to be so severe that the patient has to go to the ICU." ۔

Both Dr. Amish and Dr. Shu Yuan Xiao said that in some very sick people, lung function may not be fully restored.

Protected from antibodies and viruses
People with the disease develop antibodies that act against it when the disease relapses, and the same is true of the corona virus.
