Dr. Tony Holohan:

I will put words rather than numbers on it because the numbers are extremely small. The practices we had in place last winter to restrict the transmission of Covid-19 practically obliterated influenza in the northern hemisphere. That was our experience in this country.

Each winter, we track the rate through our sentinel GPs, of whom there are 60 around the country, of influenza-like illnesses, which have a constellation of symptoms consistent with the flu. We saw a rise in that that was almost exclusively Covid. We detected almost no flu over the course of last winter.
