We are still treating people as infectious if they have a fever so you should continue to quarantine. You cant prove that your wife isnt infectious or that you arent asymptomatically carrying it. Check your local guidance on whether you should be socialising with others regardless of your Coronavirus status.
My wife tested positive for COVID-19 several weeks ago and has now had a fever for over a month, while I am asymptomatic. We have been quarantined for the entire month and have not left our house. Her doctor recently gave her antibiotics as she believes my wife has a secondary infection that is causing the fever to linger. Is it safe for me to see family (while maintaining 6 ft/mask/etc of course)?Edit: My family has also been self-quarantined, they are relocating to their vacation home which is close to me.
