Flu is tracked from Asia and then it travels to Europe and North America and then down to South America. The US always watches Asia to decide what flu strains to put in the vaccines for the upcoming flu season.
According to this https://www.who.int/teams/global-influenza-programme/surveillance-and-monitoring/influenza-updates/current-influenza-update WHO is reporting still low levels of flu in Asia, but the best would be for us to actually look up data for East Asian countries and see their flu numbers this past flu season (just ending now) and 3,4,5 years ago and how it compares.
I think flu in the US will be higher this year than last year in the US since people are flying, cruising internationally, and moving around a lot domestically, but I still expect it to be fewer cases of flu than average years here.
Children are being masked in schools still, airplane travel is still masked, when COVID rises in a community masks and distancing increases. All those things will reduce transmission of flu. That’s assuming flu vaccination stay constant compared to most years also.
That’s my OPINION.
