I personally wouldn’t be surprised if it was here over a year ago.
I had something
Thanksgiving 2019,,,
I agree that it may have been around for over a year. My boyfriend died in March of what they labeled Idiopathic Pulmonory Fibrosis. It came on suddenly and he declined quickly. When he was put on oxygen I began to wonder if it was contaigeous because my lungs and breathing seemed to be affected. (Meaning we both could have had it unknowingly but I was in better health and able to shake it off.)
