Final answer:
The first high incidence of HIV/AIDS in the New World was in the United States, with the HIV/AIDS epidemic identified in 1981. Better access to treatments in the U.S. allows for more survivors compared to Africa, where medication is less available. Sub-Saharan Africa, however, remains severely affected by HIV/AIDS, accounting for nearly 70% of the world's HIV-positive cases.
Step-by-step explanation:
The first country in the New World to experience a high incidence of HIV/AIDS was the United States. The history of the HIV/AIDS epidemic began with its identification in 1981. HIV, which likely crossed over from monkeys to humans in West Africa, soon spread across the globe. Despite efforts to curb the spread of the virus, the hardest hit region is sub-Saharan Africa, due to a lack of medication access, among other factors.
In comparison to Africa, the United States has a relatively large number of people living with HIV/AIDS. Several reasons contribute to why there might be more survivors of HIV/AIDS in the U.S. compared to Africa. In the U.S., there is better access to healthcare, more advanced treatments that can manage the disease, and a higher level of public health infrastructure. Moreover, broad public health campaigns, the availability of preventive measures like condoms, and the declining cost of treatments have helped to reduce the spread and impact of the disease.
However, it's important to highlight that the epidemic continues to be a devastating issue, particularly in sub-Saharan Africa, where nearly 70% of the world's HIV-positive cases are located. The international community continues to face significant challenges in addressing this health crisis, with the social stigma associated with HIV/AIDS further complicating efforts.
