COVID symptoms: Do you have symptoms if you never had COVID-19?

There are still thousands of COVID-19 cases per day across the United States. But questions are rising about those who never caught COVID-19 – or at least those who thought they never had COVID-19.

Driving the news: Dr. Zania Stamataki, a senior lecturer and researcher in viral immunology at the University of Birmingham, recently explored this topic in a piece for The Guardian.

  • “Some people may clear the virus quickly because they have pre-existing antibodies and memory immune cells that recognize the virus,” Stamataki wrote.
  • “There is also a possibility that different immune systems respond differently to the virus.”
  • “It is also possible that some of us may have rare types of ACE2 that the coronavirus spike can not stick to.”

Symptoms: Dr. William Schaffner, an infectious disease expert at Vanderbilt University School of Medicine in Nashville, said that there are people who might have COVID-19 but would never know it because they either did not have COVID-19 symptoms or blamed their COVID-19 symptoms on something else, according to WebMD.

  • “People may have conceivably – but we can not define them yet – different capacities to ward off viruses or bacteria,” he said, per WebMD.

Yes, but: Schaffner said those who never had COVID-19 should not assume they have “a suit of armor.”

What’s next: Axios reported that the “never COVID” group could help scientists understand how to build a vaccine that could protect the world against new variants.

  • John Brooks, chief medical officer for the Center for Disease Control and Prevention’s COVID-19 Response Team, told Axios that the idea of ​​the “never COVID” group is “very intriguing,” but “we do not know very often why someone did or did not get infected in sufficient detail to nail it. ”
