From someone in the thread, "Covid may indeed be similar to flu but as you have stated, currently there is no immunity."

Maybe I am not following clearly, but I keep hearing we've tested so many hundreds of thousands across the US, and (you choose a number) 10-40% respond as Covid-exposed, and then of those only a smattering need health care, maybe 10%, and of those - 90% recover.

If we've been exposed, and are still living, with or without symptoms, aren't we in the process of creating this mystical "herd immunity"? Aren't we creating immunity by fighting off death by Covid?


Not necessarily. Once you've been exposed to some virus's, for example chickenpox, you have life long immunity, for others the immunity may fade in months. We do not know how long immunity after being exposed to SARS-Cov-2 is yet as it has not been around long enough to build the data, but a number of the other Corona Virus's we do know about which are responsible for some versions of the common cold have their immunity fade in months, which is one of the reasons why you can keep getting colds.

I have not had a cold in thirty plus years. Had a few other issues, skeletal/soft tissue from an athletic lifestyle. I credit much of my lack of common colds and flu to not having children. My stress levels are lower, I have more disposable income and free time. I chose whom to be around and with the money I have saved I can hire strippers to care for me when I am old. Got to get your health wherever you can! Stay safe out there pilots.
