HIV infections and disease progression in Humans

  • The course of HIV infection and disease progression may span for a decade.
  • Stages of HIV infections include:
  1. Primary infection
  2. Dissemination of virus to lymphoid organs
  3. Clinical latency
  4. Induction of HIV expression
  5. Clinical disease
  6. Death
  • The duration between primary infection and progression to clinical disease averages about 10 years.
  • Death usually occurs within 2 years after the onset of clinical symptoms.
  • Following primary infection, viral replication occurs and the virus in blood (viremia) is detectable for about 8-12 weeks.
  • Virus is widely disseminated throughout the body during this time, and the lymphoid organs become affected.

I was told that only after 7 weeks of having sex with an HIV positive person the virus can be detected in a healthy [HIV negative] person. During this 7 weeks period the HIV multiply and grows. My question is, during this period, can a strong immune system can fight off the HIV and defeat it, kill it? For example, if I'll eat only healthy food, exercise, etc' - and have a strong immune system, I can prevent myself from having AIDS? Even though I had unprotected sex?

According to my calculations, at least a billion people are now infected, and a million more are being infected every day. Can you comment on this?

hi people! AIDS can affect anyone anywhere. The best way is to protect yourself from any kind of unprotected exposure like sex workers, multi-partner sex, syringes, blood transfusion etc. Though women are more susceptible, men are equally receptable to infection. Symptoms as such could'nt be monitored. Its usually associted with decreased immunity with consecutive infections. The virus may not show itself to a maximum of 10 years. The only way is to check urself for HIV virus. Bye . Have a safe life
