Yeah, I've wondered the same things myself. All I know is that my hematologist says he has researched the hell out of this and figured out a lot. He seemed content that he knows enough now. He's one of the highest respected oncologist/hematologists in our area. Im glad i have him. He told me the coumadin will protect me.
I dont think anyone should take meds prophylactically unless they are a health care worker and its doctors orders.if you do get sick with the virus, consult with a good doctor.
The neighbor girl has it and just has bad cold symptoms, but she's only 19 years old. For those of us older and with health problems I would definitely ask a doctor for help.
