Imagine that someone was in..

when would he/she find out he/she is infected without a blood test?(i mean symptons)

It depends on when it changes from HIV positive to active AIDS. Factors that differ from person to person affect how the effect will be established. It might never happen and with treatment can be controlled. NO doctor or person can give you a date with any certainty until the last six months of life.

You would never realy know unless you got poorly would you....

after some hours - nothing

you need weeks and months to start showing symptoms

Nothing, it might only show after weeks on a blood test. and if it's HIV you might just be OK all your life and never get AIDS. Symptoms well when you're in a far stage of AIDS it can be a bit like a flu, lung problems....

its a bad question, the HIV is very bad subject, go to any clinical test without waiting for surprises

signs and symptoms would not appear until months or years later. They are usually fatigue, sweats, and dementia. Most of the time a blood test won't even tell you have HIV until at least 6 months after being infected

i dont want to imagine that. but i heard that the effects of the viruses would be arised in 2-3 years time.
