Hi, I'm A Nineteen Year Old Male. Just Wanted To

hi, I'm a nineteen year old male.
just wanted to ask if was it possible to catch some sort of disease if I swallow someone else's blood by mistake ??
it wasn't a mouthful, but it was more or so like a tablespoon and of course the person wasn't infectedand I didn't get sick after that, but I just needed to know if had to diagnose myself I need a response immediately . thank you .
