How many cases of AIDS are there in the United States?
The latest data I can find is from the end of 2003, so the numbers will be slightly higher today. The prevalence of HIV positive individuals is estimated to be between 900,000 and 1 million people in the United States (many do not know they have the disease, so that's why there is only an estimate). The prevalence of patients with AIDs in the United States is just over 400,000. There are about 45,000 new cases of AIDS each year.
There were early cases that looked like AIDS in 1959 (UK and US) and 1969 (US). There is some doubt now about these. In 1976 a sailor in Norway was diagnosed with AIDS, which he probably contracted in Cameroon, in Africa between 1960 and 1966. In 1977 a Danish surgeon who had worked in Zaire was diagnosed. There were several cases in 1978. By the early 1980s there were many cases in the US.
Do you mean " How many states are in the Continental United States?" If so, there are 48. The continental United States refers to the states that are connected by borders. Hawaii & Alaska are located away from the other states, therefore they aren't considered to be in the Continental United States.
This question weighs heavy on the minds of many people after they find out they are infected with HIV or get and AIDS diagnosis. There are many social service agencies in the United States that help provide counseling and services to those infected with HIV. I would suggest going to to the related link and look for resources there. That website is the most comprehensive HIV site online.
