Long-Haulers Are Redefining COVID-19
“Long-Haulers Are Redefining COVID-19”
I suspect the Covid-19 is like HIV where it can hide in other parts of the body. The virus level drops to a point where it cannot be detected with the Nasal swab. It is sitting there waiting for the immune system to drop before coming back out again.
The Nasal swab is for detecting respiratory illness infections. Covid-19 might be a Vascular Disease too. Once a patient inflected the virus starts in the respiratory areas then moves through the blood to spread throughout the body.
They might need to develop a blood test for active Covid-19 instead of just antibodies.
