Doctors expect to see more patients sick with COVID-19, the flu and a range of other viruses this autumn, but Boston Medical Center’s Dr. Katherine Gergen Barnett says not to panic.

"These are things we've had in the past, and we'll get through it," she said.

Gergen Barnett joined Boston Public Radio on Monday for another edition of “Ask the Doctor,” updating us on the current state of COVID-19, this year’s flu season, and more. Here’s what you need to know:

Where does the United States stand with COVID-19?

During a “60 Minutes” interview last month, President Joe Biden declared that “the pandemic is over” — a comment that prompted backlash from the public. Dr. Katherine Gergen Barnett stressed that the pandemic is not over, with recent local wastewater data showing an uptick in COVID-19 cases.

“We are on track to have about 100,000 deaths per year, and deaths per week that are equal to 9/11,” Gergen Barnett said. “I think it’s really important to remember what we have gotten used to.”

What can we expect for this flu season?

While influenza is unpredictable, infectious disease experts typically look to Australia and New Zealand’s flu season for a preview of what’s headed to the U.S. The two countries’ flu season lasts from April to October – winter in the Southern Hemisphere. And with Australia experiencing its worst flu season in five years, Dr. Gergen Barnett expects this flu season to be tough.

How can I tell if I have COVID-19 or the flu?

Common symptoms of COVID-19 and the flu are similar: sore throat, sniffly nose, aches, etc. Gergen Barnett suggests that those feeling sick but test negative for COVID-19 look for clinics offering PCR tests and flu tests.

“Definitely take [an at-home COVID-19 test] every 24-48 hours, and if you’re still not feeling well and those tests are negative, you can go get a PCR test,” Gergen Barnett said. “When you get the PCR test, you should also get swabbed for the flu.”

When should I get my shots?

Gergen Barnett said people should get a COVID-19 booster as soon as possible. She also said Dr. Anthony Fauci recommended people get a flu shot by Halloween.

Doctors say it is safe to receive both a COVID-19 booster and flu shot at the same time.

You can find a COVID-19 vaccine provider by searching the Massachusetts VaxFinder tool.
