My son is 2 and for the last 7 days, he has been pooping bloody mucus. I have taken him to the doc and the er and they all keep telling me that it s just a virual thing. They took one stool sample and said everything was fine, but than took another to do more test. My son weighs 30 lbs and is about 2 feet tall What could be causing this other than a viral thing?
Bloody stool is never due to viral infection. It may be due to bacillary dysentery or worm infestation.  Stool for occult blood/ ova n cyst along with culture needs to be done.
