Researchers say COVID symptoms have changed

Since the start of the COVID-19 pandemic, patients have reported dozens of different

symptoms, ranging from cold and flu-like symptoms to more unique ones, including “COVID tongue.”

Now, medical researchers say there has been a change, an 'evolution' if you will, in the most common symptoms of COVID-19 infection.

A study involving hundreds of volunteers has found that for participants in all three groups — fully vaccinated, those who received just one dose, and unvaccinated — four of the five most commonly reported symptoms are the same: sore throat, runny nose, persistent cough, and headache.

Their prevalence across the groups, however, varies, as does the fifth symptom.

For those who are vaccinated, a blocked nose is the third-most frequently reported symptom. Among the partially vaccinated, it’s sneezing, and for the unvaccinated, it's fever.
