Some people who get COVID have ongoing symptoms, new symptoms, or symptoms that go away but return. This condition is commonly called Long COVID.
It has been challenging to know whether symptoms are really due to the ongoing effect of COVID infection or is due to a different cause.
The NIH has developed a research study, named RECOVER, that is intended to identify symptoms after COVID infection that can reasonably identify people with Long COVID.
People who had COVID were compared to people with similar characteristics such as age, sex, race, and the like Both groups were questioned about the presence of symptoms that may be associated with Long COVID.
Those symptoms that were more common 6 months after an initial infection in people who had COVID compared to the control group were considered to be a result of COVID rather than some other coincidental cause.
There were 12 symptoms that were significantly more common among people who had COVID. In order of frequency they are: postexertional malaise (after physical exertion having a feeling of being unwell and often lacking interest in things that used to interest them), fatigue, brain fog, dizziness, GI symptoms, palpitations (unusual awareness of heart beats), change in sexual desire or capacity, loss of or change in smell or taste, thirst, chronic cough, chest pain, and abnormal movements.
Six of these symptoms were the most common; in order of frequency they were: postexertional malaise (87%), fatigue (85%), brain fog (64%), dizziness (62%), GI symptoms (59%), and palpitations (57%).
While these findings are not yet definitive, they are able to be used to determine if a person has Long COVID. Your odds of having Long COVID, increases the more of these symptoms you have.
My suggestion is for you to see your doctor if you have one or more of these symptoms several weeks after an acute episode of COVID.
