What I’ve been told is that a bacterial infection is typically associated with a productive cough, which you don’t have. It sounds like you have coronavirus but it isn’t a guarantee so talk with your doctor or local coronavirus hotline about this to get more information.
Feelings of heat and intense sweats are other symptoms of coronavirus. Those are both related to fevers.
I have no idea if your hair shedding is a result of coronavirus or just natural. It’s not really the priority of the medical community right now, even if it were because of an infection. I wouldn’t think hair shedding is anything unnatural unless you have clumps of hair falling out.
Do you live by yourself or with other people? If you live with other people, you have to make sure to stay away from them but they can help you with some basic things like picking up essential items and food. If you are by yourself, you need to quickly acquaint yourself with your local delivery services.
