Why our testing is so inadequate to control COVID

A study published in JAMA Network Open is a great reminder about the need for way, way, way more testing of asymptomatic individuals if we’re really gonna make a dent in controlling the spread of COVID.

In this analysis, the researchers estimate that “transmission from asymptomatic individuals was estimated to account for more than half of all transmissions” of COVID.

In other words, half the positive cases of COVID probably get their infection from someone who has no symptoms, and who consequently would not come to the attention of the public health authorities.

Depressing, yes, but just a terrific reminder that you never know where or from whom you may get infected, so please continue to use all those prevention strategies that lower your risk of infection from any source.
