Fever with flu, Can I still breastfeed?

anon
I'm currently fighting a fever 🤒  Having runny nose and sore throat. Body aches.
My question is, can I still breastfeed my son? Everyone in my family is telling me not too, because I can pass my 2 month old my sickness 😕
I have no idea what to do.
He usually co-sleeps with me as well. 😞
