Viruses like flu could complicate COVID-19 fight, top doctor says, as B.C. prepares for potential fall 'surge'

B.C. health officials are urging the public to stay vigilant and to "stamp out" COVID-19 before another potential wave of infections later this year hits the province at the same time as seasonal influenza.

Provincial health officer Dr. Bonnie Henry said the province is preparing for future spikes in case numbers, saying there's "very much a potential of a surge to come in the fall."

Henry was responding to a question about preparations in the U.S., whereRobert Redfield, director of the Centers for Disease Control and Prevention, said a "second wave" of casescould be "more difficult and potentially complicatedbecause we're going to have flu and coronavirus circulating atthe same time."

Redfield said Wednesday that the combination would put even greater strain on the nation's health-care system than the initial outbreak.

Echoing those concerns, Henry said COVID-19 may become harder to identify when other virusessuch asinfluenza and respiratory syncytialvirus (RSV),a common virus that can causecold-like symptomsbecome more widespread.

"Once we have influenza complicating things, and the other respiratory viruses that we see, it's much more challenging to detect which one is influenza, which one is RSV...which one is COVID-19," she said.

She said health researchers don't know yet if there is a seasonality to the coronavirus that causes COVID-19, so monitoring the number of casesis important.

"That's one of the things we are working very hard to have in place, the surveillance that we need, the testing that we need, the contacttracing in our community that we need," Henry said.

She saidit's important for people to do as much as possible now to stop the spread of COVID-19 by following health orders such as physical distancing.
