Final answer:
The specific number of new HIV infections in the U.S. per year is not provided, but there has been a global decrease in new infections and a significant decline in AIDS-related deaths in the U.S. due to antiretroviral treatments. Disparities in healthcare access contribute to varying survival rates, with more survivors in the U.S. compared to Sub-Saharan Africa.
Step-by-step explanation:
The number of new HIV infections per year in the U.S. has not been specifically provided in the provided information. However, it is important to note the overall global trends that have been observed in the fight against HIV/AIDS. While the annual number of new cases of HIV has shown a decline globally, from 3 million in 2001 to 2.7 million in 2005, according to United Nations data, and mortality rates have also seen a reduction due to the effectiveness of antiretroviral treatments, the disease remains a significant issue in many parts of the world.
In the United States, antiretroviral therapies have contributed to a 70 percent decrease in AIDS-related deaths over a period of 15 years, but disparities persist, particularly among low-income African-American communities, where AIDS remains a public health crisis. These treatments, combined with better healthcare infrastructure, could explain why there may be more survivors with HIV infections and AIDS in the U.S. compared to regions like Sub-Saharan Africa, where the number of people living with HIV/AIDS is higher and access to care is often more limited.
Understanding the difference between the incidence and prevalence of HIV is crucial. Incidence refers to the number of new cases reported within a specific time frame, while prevalence refers to the total number of existing cases at a given point in time, including both newly diagnosed and long-term cases.
