What he said: “If a symptom is affecting your ability to work or your ability to accomplish your normal day-to-day activities, tell your healthcare provider,” Khabbaza said.

  • “There may not always be some intervention that can be done, but COVID changes every day. We learn more every day and there are so many moving parts. If you’re having difficulty, you always want to make sure your healthcare provider is aware of everything.”

The bigger picture: The BA.2 coronavirus variant — a subvariant of the omicron variant — became the most dominant COVID-19 strain in the United States this week, according to the Centers for Disease Control and Prevention.

  • The BA.2 COVID-19 variant now makes up about 54.9% of all new COVID-19 infections in the United States.

What to watch: The Food and Drug Administration Tuesday authorized a second COVID-19 vaccine booster shot for Americans 50 and older, warning of potential new variants and the continued spread of the virus.
