The Covid-19 virus is a different sort of virus. We are seeing signs of this as it is studied.

We Still Don't Fully Understand The Label 'Asymptomatic'
"Even if someone is infected by the novel coronavirus and remains asymptomatic — free of coughing, fever, fatigue and other common signs of infection, that doesn't mean the coronavirus isn't taking a toll. The virus can still be causing mild — although likely reversible — harm to their lungs.
A new paper in
Nature Medicine, published June 18, documents the clinical patterns of asymptomatic infections. It finds that many of the people studied developed signs of minor lung inflammation — akin to walking pneumonia — while exhibiting no other symptoms of the coronavirus."

Researcher: Asymptomatic Coronavirus Patients Can Still Face Organ Damage
"New
analysis from Scripps Research has found that anywhere from 30 to 40% of people with coronavirus are asymptomatic, but that doesn't mean they aren’t impacted by the disease.
Scripps Research cardiologist Eric Topol and his colleagues looked at research on over a dozen cohorts of coronavirus patients around the world. He found many of the patients that were asymptomatic still incurred lung abnormalities."
"But the other thing that we uncovered that was a surprise to us, and I don't think most people know this, is that even though you don't have symptoms, which is silent enough as it is, there's another level of silence, which is you can have internal organ damage and not know it."
One study looked at CT scans conducted on individuals aboard the Diamond Princess cruise ship. In that case, 54% of 76 asymptomatic individuals showed significant subclinical lung abnormalities"

COVID-19: Damage found in multiple organ systems | MDLinx
" Almost half of all patients with COVID-19 have evidence of blood or protein in the urine, indicating early kidney
damage, according to Alan Kliger, MD, a nephrologist at Yale University. In addition, early data has shown that around 15% to 30% of patients with COVID-19 in the ICU in New York and Wuhan, China, have required dialysis or continuous renal replacement therapy. "

Half of coronavirus patients with NO symptoms may have lung damage
"Coronavirus patients without any symptoms can still suffer organ damage - often silently - a new study suggests.
Researchers analyzing public datasets found that as many as 45 percent of people infected with COVID-19, the disease caused by the virus, never have traditional signs such as coughing, fever or shortness of breath.
What's more, in one of the datasets, more than half of asymptomatic patients had CT scans with signs of serious lung damage."
So even if someone survives the virus, there are serious health issues to deal with. And the fact that they have found lung damage in people who were asymptomatic is a new level of problems.
