People who have recovered from Long Covid can suffer relapses or flare-ups from new viral infections — not just from COVID but from cold, flu, and other viral pathogens, researchers have found.

In some cases, they may be experiencing what researchers call viral interference, something also experienced by people with HIV and other infections associated with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).
Clinical studies on the issue are limited, but patients, doctors, and researchers report many people who previously had Long Covid have developed recurring symptoms after consequent viral infections.
Anecdotally, these flare-ups occur more commonly in patients with Long covid with autonomic dysfunction — severe dizziness when standing up — and other symptoms of ME/CFS.

Patients can “recover (or feel recovered) from Long Covid until the next immune challenge — another COVID infection, flu infection, pregnancy, food poisoning (all examples we have seen in the clinic) — and experience a significant flare-up of your initial COVID infection.”

MEA Comment
It is well recognised that new infections are a very common cause of an exacerbation of symptoms, or sometimes a more prolonged relapse of ME/CFS.
So, it comes as no surprise to find that researchers have concluded that the same situation applies to people with Long Covid.
The ME Association has an information leaflet covering the causes and management of exacerbations and relapses in ME/CFS. People with Long Covid will also find this information helpful.
