Final answer:
The exact figure for adolescents aged 15-19 diagnosed with HIV in 2013 is not available in the provided references. The data highlights the severity of the HIV/AIDS epidemic, especially in sub-Saharan Africa and among young people.
Step-by-step explanation:
The specific number of adolescents aged 15-19 diagnosed with HIV in 2013 is not provided in the provided information. However, the data suggests an overall high prevalence of HIV/AIDS within certain demographics and regions, particularly in sub-Saharan Africa. It is important to note that access to health care plays a significant role in the diagnosis and treatment of HIV/AIDS, and that adolescents are included in the recommended age range for HIV screening in the United States.
The global HIV/AIDS epidemic has dramatically affected millions, with a significant number of infections occurring in young individuals below the age of 25. The spread of the disease is notably severe in low- and middle-income countries, and despite progress in treatment, HIV still remains one of the leading causes of death globally.
