I read the second article and still fail to see where you get your number. I did find these statements...
“The new coronavirus and the disease it causes are still just months old,
meaning researchers have not been able to study the disease's long-term effects on people.”
“Physicians report that patients hospitalized for Covid-19 are experiencing high rates of blood clots that can cause strokes, heart attacks, lung blockages, and other complications, ...
For instance, physicians are seeing an uptick in strokes among young patients with Covid-19.“
“Physicians have also found evidence of scarring in Covid-19 patients' lungs. According to Parshley, some CT scans show Covid-19 patients have light gray patches on their lungs called "ground-glass opacities," which don't always heal. One Chinese study found the patches in 77% of patients, Parshley reports.
Brennan explained that the "virus creates an incredibly aggressive immune response" that causes "spaces [in the lungs to be] filled with debris and pus, making your lungs less pliable." According to Brennan, this type of lung damage can be permanent and could result in reduced lung capacity. "Routine things, like running up a flight of stairs, would leave these individuals gasping for air," he said.
While it's too soon to tell whether the lung damage in Covid-19 patients will be permanent,
researchshows that about one third of survivors of similar coronaviruses such as SARS and MERS had long-term lung damage.“
“Physicians have also reported an increase in inflammation of and damage to the heart muscle in Covid-19 patients. One
study published in March found that out of 416 hospitalized Covid-19 patients, 19% showed signs of heart damage.
Another
study from Wuhan published in January found 12% of Covid-19 patients showed signs of cardiovascular damage. Other studies have since found evidence of myocarditis, inflammation of the heart muscle that can cause scarring, and heart failure in Covid-19 patients.
Now, physicians warn that Covid-19 survivors may experience long-lasting cardiac damage and cardiovascular problems, which could increase their risk for heart attack and stroke. Doctors also warn Covid-19 could worsen existing heart problems.”
“Physicians and public health experts say more research—and time—is needed to understand the long-term effects of Covid-19 and the complications patients might encounter down the line and whether they have a chance of recovery.”
Even in the second article there is a statement of how unknown the long-term effects will be. It is too soon to know.
Nowhere did I see your 5% or a fraction of that percentage mentioned. Research is ongoing with no final numbers in the record. But the closing statement of it’s not a matter of if but when effects go away sort of comes from left field. There is nothing prior to that statement that backs this up. Both articles are reporting on what is currently being seen along with the clear statement of “we don’t yet know” anything because we’ve only been dealing with this stuff a few months.
There are patients recovering well. But there are many who are not. It is not known if courses of treatment make a different or if there is something else just not yet found. To quote a study done at some point in March saying this is it is nowhere near accurate. Until the virus is over and real longterm effects can be studied, you can’t say the effects do not linger nor permanently remain with a person.
