Baby suddenly refuses to latch

Ever since my boy had hfmd, he stopped latching. He has since recovered from hfmd, but it has been almost a month but He still refuses to latch. Each time I tried, he will turn his head away or push away from my boobs. There's no way to make him latch, he will even cry murder each time i tried to latch him. Is there any methods to coax him back to latch? Or it this a sign that he do not want to latch anymore :( I've veen trying, I'm a working mom. So each time I'm around, i will try offer boobs first. But he seems to hate my boobs alot now :(
