For how long have you been healthy now? When was the last day of fever? How do you feel at the moment?
You should only train if you feel totally healthy. Start slow and see how your body reacts. Don’t force anything and take it day by day. When in doubt do less. And never push through anything!
First thing should always be to be healthy. And every training is better then getting sick again and not being able to train at all.
So focus on health first and support your immune system. Everything else will follow.
This is what I would recommend.
Hope that helps!
