More than a year into the coronavirus pandemic, experts have unraveled so many mysteries about how to treat the virus and prevent it. But at the same time, SARS-CoV-2 is always changing as new variants emerge. And accordingly, the ways in which the virus affects people seem to be shifting as well.
Here’s a quick rundown of some of the most common COVID-19 symptoms doctors are seeing right now, and how vaccines and variants fit into this picture.
The most common symptoms — such as cough, fever, and loss of taste and smell — are all still pretty much the same.
Since the COVID-19 pandemic began, the most common symptoms of the virus included a cough (often dry), shortness of breath, a fever of 100 degrees or higher, and the sudden loss of taste and smell.
Those, however, are by no means the only frequent symptoms. People also report everything from headaches to diarrhea, all of which are listed on the Centers for Disease Control and Prevention’s rundown of common possible symptoms.
For the most part, that list of the most common symptoms hasn’t really changed. “The symptoms are really the same as before. It’s the headache, cough, fatigue, runny nose, fever — those kind of generalized flu-like symptoms,” said Jonathan Leizman, chief medical officer of Premise Health, a health care company headquartered in Tennessee.
The emergency warning signs of COVID-19 have also stayed pretty much the same. Those include issues like trouble breathing, persistent chest pain or pressure, and new mental confusion.
With the delta variant, some people’s symptoms might look more like a common cold.
The delta variant (B.1.617.2) is circulating widely around the globe and is now the main strain here in the United States; it’s hitting areas with high numbers of unvaccinated Americans particularly hard.
There is some initial evidence that the symptoms associated with delta might be a bit different than those with the original SARS-CoV-2 virus, though experts caution that it remains too early to say definitively.
“The information we’re getting from the U.K. and Europe and some initial surveys here in the United States is that the delta virus infection seems to be more likely to produce symptoms that are more typical of a common cold,” said William Powderly, co-director of the Division of Infectious Diseases at Washington University School of Medicine in St. Louis, which has recently seen a big uptick in COVID-19 cases and hospitalizations. “That’s a sore throat, mild cough and nasal congestion.” ...
