SARS-CoV-2 attacks the alveolar sacs by penetrating pneumocytes of the lung in the alveolar sacs, where gas exchange occurs. It does this in asymptomatic and symptomatic patients. That is where the virus replicates and survives. The attacked pneumocytes die or are severely damaged. At this point if things go okay, the patient can recover. But, here is what else happens. Type 1 pneumocytes, those that are exposed to lung gases, get destroyed and are then replaced by Type 2 pneumocytes, those that normally are underneath Type 1. They cannot fulfill the role of T1P. Then, because of the invasive nature of SARS virus, lymphocytes invade the alveolar sack, filling it with lymphatic pus. They will kill off the Type 1 cells that have virus. These are the cells that do gas exchange. Everybody will end up with some type of reduced gas exchange at the end of this disease. But, the job of Type 2 is to regenerate and differentiate into Type 1 cells upon their death. So, there is that. But, in this disease, the regeneration of Type 1 cells can be blocked by the development of fibrosis, which means those nice little Type 2s will not be able to complete their mission. And, when that happens to that alveoli, game over for that spot on the lung to recover. That spot is now gone for the duration and no more gas exchange at that location.
The sequelae of the disease, or after the disease is either flu like symptoms, pneumonia, acute respiratory distress syndrome (really bad news), the diffuse alveolar damage (see above but in a grand scale), hypoperfusion of organs (lack of blood supply), which leads to multi systemic organ failure.
The key after disease onset is DAD, which is not fully understood why this coronavirus can show with DAD in asymptomatic (no shown symptom) patients.
But, here we are discussing opening training camp. We all want to see more glory from this years squad. We desire to see spring football, summer camps, fall games, winter bowl (NC game, of course!).
And, I want to see no DAD in our team. I am not sure how to ensure that happens. Do we social distance? Do we test and isolate the team from society during camp? Do we test every kitchen worker, team trainer, coach, administrator, delivery guy, janitor that comes in contact with the team to ensure that none of the team member has the side effect of DAD? I don't know. That is a decision above my pay grade. What I do know, is this is not a disease I want to have. I don't wish it upon anybody, young or old. DAD can and is occuring in the young to some degree in all cases. Most are very limited. But, some, are noticeably worse in young people. I don't have the numbers. This is an area of Covid-19 where we won't know for a while what are the numbers.
This search for numbers will open up society. It was just yesterday that a national plan for testing was approved. We are still working out the supply chain, getting testing to be more reliable, and for it to be widely available.
I will not be responding to posts. Argue among yourselves.
