With shots and infections, the most common COVID symptoms have shifted

The most common symptoms of COVID-19 have changed, making it more difficult for people to distinguish between the two infections.

The ZOE COVID Study, an app-based study with over 4 million users, was created by researchers at Massachusetts General Hospital, Harvard University, King's College London, and ZOE.

Common symptoms that have topped standard lists include a persistent cough, a cold, and a feeling of weakness in the lungs. The loss of taste and smell was a telltale sign of the virus. The top five don't have those symptoms anymore.

The top five symptoms of a breakthrough infection are sore throat, a blocked nose, a cough, and headaches. Only persistent cough remains from the original list of top symptoms. The sixth most common symptom was a loss of smell, followed by a sore throat. The shortness of breath was ranked 29th.

The top five symptoms are similar to those seen in fully vaccineed people. The most common symptom in the unvaccinated and partially vaccine groups is headaches. The unvaccinated reported that they had more sneezing, and the partially vaccined reported that they had more fever. The data did not include the number of times respondents had been bitten by the disease.

There are a number of reasons why the symptoms have shifted to milder ones. Immune protection from previous vaccinations protects against serious disease. Younger people tend to have less severe symptoms than older people when they fall ill in recent weeks.

Sneezing has risen in the ranks of COVID-19 symptoms, making the top five for partially vaccined people. Sneezing is one of the most effective ways to spread the disease. People should be cautious if they suddenly experience a sneezing fit.
