HIV Testing Did Drop During COVID — But "Nearly 25 Percent" Is Too Neat a Number
“HIV testing declined by nearly 25 percent in high-burden settings”
The argument in brief
The claim that HIV testing fell by nearly 25 percent in high-burden settings during the COVID-19 pandemic contains a real kernel of truth, but the single figure is misleading. Actual declines varied wildly — from under 10 percent in some countries to over 50 percent in others at peak disruption. UNAIDS, WHO, and PEPFAR all confirm serious disruptions, but none consistently cite a uniform 25 percent figure.
Data: UNAIDS/WHO/PEPFAR compiled reports, 2020-2021
Why it spread
A specific percentage feels like proof. It sounds like someone did the math, so people share it without digging into whether that number actually holds up across contexts. The claim also touched on something people were already worried about — that the pandemic was quietly wrecking other health services — which made it easy to accept at face value.
The claim is that HIV testing declined by nearly 25 percent across high-burden settings — a figure that sounds precise and alarming. The verdict: partially false. HIV testing was genuinely disrupted during the COVID-19 pandemic, but the real picture is far messier than a single number suggests.
Multiple major health bodies confirm the disruptions were real and serious. UNAIDS's 2021 Global AIDS Update found that testing volumes dropped significantly in 2020, with some high-burden countries reporting declines anywhere from 10 percent to over 40 percent depending on the country and the month. The WHO's Global HIV Programme COVID-19 Impact Report found that Sub-Saharan African countries alone saw declines ranging from modest reductions to over 50 percent in some months. A single average simply cannot capture that spread.
The Lancet HIV published modeling that estimated a 6-month interruption of HIV services could cause significant increases in HIV-related deaths, with empirical data showing testing declines of 20 to 50 percent in various high-burden settings during peak disruptions. In the United States, CDC data showed HIV diagnoses fell roughly 17 percent in 2020 — though that number blends actual changes in transmission with reduced access to testing, making it hard to interpret cleanly.
PEPFAR's 2021 Annual Report to Congress adds important nuance: programs in supported countries largely recovered by late 2020. Some countries held services steady while others saw dramatic drops. Treating all of them as a single 25 percent story erases the variation that actually matters for public health response.
This kind of misinformation is tricky because it is built on real events. HIV testing really was disrupted. The danger is that a tidy, authoritative-sounding number gets repeated until it hardens into accepted fact — and then gets used to draw conclusions that the messy underlying data cannot support. When you see a single percentage applied uniformly across dozens of countries with very different health systems, that is a signal to look closer.
Sources
- UNAIDS Global AIDS Update 2021
UNAIDS reported that HIV testing services were significantly disrupted during the COVID-19 pandemic in 2020, with some high-burden countries reporting declines in testing volumes ranging from 10% to over 40% depending on the country and time period, but a uniform 'nearly 25%' figure is not consistently cited.
- WHO Global HIV Programme COVID-19 Impact Report
WHO documented that HIV testing disruptions during COVID-19 varied widely by region and country. Sub-Saharan African countries saw declines ranging from modest reductions to over 50% in some months, making a single 25% figure an oversimplification.
- The Lancet HIV – COVID-19 impact on HIV services
Modeling studies published in The Lancet HIV estimated that a 6-month interruption of HIV services could lead to significant increases in HIV-related deaths, and empirical data showed testing declines of 20-50% in various high-burden settings during peak COVID-19 disruptions.
- CDC – Monitoring Selected National HIV Prevention and Care Objectives
CDC data for the United States showed HIV diagnoses fell approximately 17% in 2020 compared to 2019, partly reflecting reduced testing access, though this conflates actual incidence changes with testing disruptions.
- PEPFAR – PEPFAR 2021 Annual Report to Congress
PEPFAR reported that HIV testing in supported countries declined in early 2020 but programs largely recovered by late 2020. The aggregate decline across PEPFAR-supported high-burden settings was not uniformly 25%; some countries saw larger drops while others maintained services.
