The Promise of Opportunistic Testing

A key lesson the HIV/AIDS pandemic can offer right now: the importance of knowing one’s status with a virus that won’t necessarily bring on symptoms.
Luckily, stigma is not the same deterrent to testing as it was early on in the AIDS pandemic. But COVID-19 testing has other limitations.
Amid the AIDS pandemic, default HIV screening of secondary care patients helped identify cases that would have otherwise been missed—particularly in the more infectious early stages.

This “opportunistic testing” also holds promise for beating COVID-19—but its success depends on the quality and the quantity of tests available, which is still very much in doubt.
