What happens if a person gets a bunch of sicknesses at the same time?

What I mean is like if a person is exposed to everything at the same time like flu, cold, ebola, aids, sars, escherichia coli, asma, chicken pox (first timer), tetanus, and anything else eye kant think of right now? and also what happenes if a person is injected by all of these viruses at the same time? no i dont want to find out by expirience but any guesses?

either they would all cancel out each other or the person would die.

the immune system is weakened if it is exposed to many viruses at once. That many viruses may weaken a person enough to become very ill. Too many viruses at once can lead to death. AIDS and one other virus can be deadly.

first, nobody should be injected with all of them at once it will overload your immunity system which fights off diseases.now if a person has this in real life they have a low immunity system maybe caused my AIDS,chemotherapy,anemia,vitamin deficiencies and the plain will to live.

if exposed to all listed, the person would die- ebola would be enough to do him in.
