Final answer:
The correct answer to the student's question is that there are 1.2 million people currently living with HIV/AIDS infection in the United States, according to the CDC.
Step-by-step explanation:
Current Statistics on HIV/AIDS in the United States
The U.S. Centers for Disease Control and Prevention (CDC) estimates that there are currently 1.2 million people living with HIV/AIDS infection in the United States. Medical advancements and antiretroviral treatments have contributed to a longer life expectancy for those infected with HIV, which is one reason the number of people living with the infection remains significant. Despite the severity of the epidemic globally, particularly in Sub-Saharan Africa where the prevalence of HIV is the highest, the United States has been able to maintain a relatively stable number of infections due to access to healthcare and effective treatment options. Option 1, which states 1.2 million people, is the correct answer to the question.
