HIV-Affected individuals' projected lifespans

In a groundbreaking shift, the current life expectancy for individuals living with Human Immunodeficiency Virus (HIV) and receiving antiretroviral therapy (ART) has significantly improved, approaching that of the general population. This progress, particularly in regions with easy access to treatment, is a testament to the advancements made in HIV treatments over the past few decades.

A recent study in China, spanning from 2013 to 2023, demonstrated a remarkable increase in life expectancy among HIV-infected patients on ART. The gap between their life expectancy and that of the general population has narrowed annually, reflecting global trends due to the strides made in HIV treatments.

However, the situation is starkly different for those with HIV who are not receiving treatment. Without proper care, life expectancy is significantly reduced due to progressive immune system damage and related complications. Before effective ART, HIV infection typically led to AIDS and premature death within about 10 years or less.

The evolution of HIV treatment began in the late 1980s with the introduction of AZT, the first HIV treatment, which offered some improvement despite limitations such as side effects and resistance. A major breakthrough came in 1996 with the advent of highly active antiretroviral therapy (HAART)—a combination of three or more drugs targeting different stages of HIV replication. This reduced mortality by about 70% within two years in the U.S. and transformed HIV from a fatal disease to a manageable chronic condition.

Since then, ART has evolved with the introduction of combination pills for easier adherence, newer drug classes like integrase inhibitors, and long-acting injectables (e.g., Cabenuva) reducing dosing frequency. These advancements have improved treatment efficacy, reduced side effects, and greatly extended life expectancy for people living with HIV.

With consistent ART, people with HIV can now expect a near-normal life expectancy. The virus is suppressed, immune function preserved, and HIV-related deaths dramatically reduced. Treatment remains lifelong because HIV persists in latent reservoirs, but modern regimens have made management more sustainable.

However, without treatment, HIV infection remains life-threatening, leading to progressive immune decline and early mortality.

In summary, the life expectancy of individuals with HIV has greatly improved due to advancements in ART. Treated individuals now live decades longer than before and often close to the life expectancy of uninfected persons. Consistent medical care and monitoring of HIV viral load are necessary to adjust treatment where necessary.

Improvements in HIV treatments have significantly increased life expectancy. The additional life expectancy for people with HIV at age 20 during the early monotherapy era was 11.8 years, but it rose to 54.9 years with recent combination ART started between 2006-2013. Life expectancy for people with HIV who have access to medical care and take long-term ART is positive, with lifespans similar to that of the general population for those with high CD4 counts.

Without treatment, life expectancy for people with HIV is dramatically lower, with those receiving an AIDS diagnosis typically living for a few years. In the early years of the HIV epidemic, many people only lived around 1-2 years after receiving a diagnosis. Older people with long-standing HIV infections can develop associated health conditions like cardiovascular disease, diabetes, kidney disease, and cancer. HIV can also affect the brain, causing a condition known as HIV-associated neurocognitive disorder (HAND).
