Most likely. Or maybe July.
But I dont think mass human spread will start until autumn or winter hits or at least gets close in the northern hemisojere (we all know things hit hard first in the North, then in the south)
By that time the virus should have mutated enough for this to happen. Plus influenza hits harder on colder weather and it might even mix up with normal flu viruses going around further increasing the death rate.
This Is actually quite scary unlike COVID since novel influenza viruses (specially avían ones) typically hit very hard and kill young and perfectly healthy people unlike coronaviruses which mostly kill old or weak people. The only scary thing about coronaviruses Is their ability to leave people crippled like how it happened with long COVID or SARS and MERS survivors. Still this Is only mostly temporally and influenza can do it too, encephalitis lethargica which Is even far more worse and causes permanent brain damage and paralysis. It happened the most during spanish flu which also caused hemorrhagic pneumonia and more crazy shit, it was the first introduction of the H1N1 virus to people, then it went extinct. You know, the swine flu of 2009 which was also H1N1 could have been as bad as the 1918 one or even worse since it was the same virus with even more virulent mutations and it has been like almost a century since the first H1N1 pandemic, but we were lucky that the same spanish flu H1N1 virus got reintroduced in the 70s due to a Soviet or Chinese lab leak when still most people did hold some degree of immunity to it so that made it way milder since there was already strong immunity to H1N1 among the population. That is why swine flu of 2009-2010 ended up being a huge nothingburger for most people but still the youngest people died.
