Whether a child or adult the figure of 7 to 10 year on average applies, but everyone is different, some are quicker than others. If you are worried that your child has HIV seek medial care, testing and appropriate treatment.
Is there anyone who can answer my question?
Sorry, I did not make it clear, I'm asking is for children 9 years old if there is no treatment, a few years will develop into AIDS.
Your question doesn't make sense. There is no such thing as a incubation period in either adults or children with HIV. There is a window period were test may not pick up the virus, this is up to 13 weeks. In terms of HIV leading to Aids, this is on average without treatment is 7 to 10 years.
Don't understand the question
