I understand the immune response and how it identifies the second time with regard to viruses.
No it isn't. (Fear mongering)
“The immune response to Covid-19 is not yet understood,” the Centers for Disease Control and Prevention (
CDC) explains. “Patients with MERS-CoV infection are unlikely to be reinfected shortly after they recover, but it is not yet known whether similar immune protection will be observed for patients with Covid-19.”
It may just be like any other coronavirus as it relates to the immune response. They don't know.
I do know anecdotal stories told by my wife about reinfection, but that could also be attributed to not being cleared really of the virus. They are not sure.
The 2,000,000 number was not based on reinfection.
It does similar serious damage to your lungs just like pneumonia does. Once you have gotten pneumonia, you can get it again much more easily, and that I do know from experience. That's not to say this is a direct comparative. I am concerned with the lung damage.
