If the body's immune system cannot fight off an infection, what happens?

Explanation:

If the body's immune system cannot fight off infection, a number of things could happen but you have to remember that it also depends on what the immune system is trying to fight off. Normally if your immune system is not strong enough to fight off an infection or virus, you will have side affects and will begin to become ill. Side affects could be as easy as a cold to something more severe such as the flu, pneumonia or as its going on right now, the corona virus.

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
