If You Have These 2 COVID Symptoms, You Could End Up in the Hospital - msnNOW

One recent study, which has not yet been peer reviewed, found that two serious COVID symptoms in particular can indicate a higher chance of hospitalization among those with long-term COVID cases—yet to the naked eye, they may seem no worse than others.

The research team behind the study used an app to gather data from over 4,100 COVID patients and found that roughly 13 percent of participants experienced "long-COVID," an extended illness lasting at least 28 days.

Though the study cautioned against generalizing based on their analysis and was quick to point out its own limitations (in particular that the study subjects were predominantly female, under the age of 70, and responsible for self-reporting their own data), this could help doctors identify serious cases of COVID sooner.

In fact, 97 percent of long-term patients reported this particular symptom, and many people reported that this was their only symptom.

The researchers found that over 91 percent of long-term patients reported headaches, while only 13 percent of the more general COVID population typically presents with this particular symptom.

The researchers found that this symptom disproportionately affects long-COVID patients, and could also indicate a more serious case.
