COVID increases the risk of secondary infections by impairing mucosal clearance.

"Our results demonstrate profound ciliary loss in the nasal epithelium even in subjects with mild disease and shed light on mechanisms that... probably predispose patients to secondary infections."

“Repeated studies show in the bluntest terms that the initial acute infection is only the tip of the iceberg. Even a mild bout of COVID can leave a legacy of blood clots, heart failure, diabetes, decreased brain function (see sidebar), long COVID (now affecting 400 million people worldwide) and immune damage that increasingly makes people more vulnerable to a plethora of infectious diseases and possibly cancers.

These problems can erupt three years after an infection”

Cryptosporidiosis was one of the original AIDS-defining conditions.
