HIV / AIDS
Roughly 630,000 deaths a year, and about 40 million people living with HIV

🧠 Understand
The trend
Deaths are down roughly 70% from the 2004 peak thanks to antiretroviral therapy — one of medicine's great comebacks — but funding cuts now threaten the gains.
The scale
On the order of 40 million people live with HIV and 1.3 million are newly infected each year. Around 9 million still aren't on treatment — which is why roughly 630,000 still die annually from a manageable condition.
Root causes
A virus spread through sex, blood and childbirth. What keeps it killing is not biology but access and stigma: people untested, untreated, or afraid to seek either.
Who suffers most
Sub-Saharan Africa carries about two-thirds of the burden; adolescent girls and young women face several times the infection risk of their male peers. Key marginalized groups face both the virus and criminalization.
Common misconception
"HIV is either a death sentence or a solved problem." Neither: a person on treatment has near-normal life expectancy and cannot transmit the virus (undetectable = untransmittable) — yet hundreds of thousands still die yearly purely for lack of access.
⚡ What actually works
Antiretroviral therapy at scale
Strong evidence
Daily pills that suppress the virus to undetectable — the person stays healthy and cannot pass it on.
Cost & effect: Generic first-line treatment costs well under $100 per person-year; treatment-as-prevention is why new infections keep falling.
PrEP (pre-exposure prophylaxis)
Strong evidence
A preventive pill or long-acting injection for people at high risk.
Cost & effect: Reduces sexual transmission risk by ~99% when taken; new twice-yearly injectables may be a turning point for hard-to-reach groups.
Preventing mother-to-child transmission
Strong evidence
Testing and treating mothers so babies are born HIV-free.
Cost & effect: Cheap, near-total protection; vertical transmission has collapsed wherever coverage is high.
