West sees early flu surge as new variant emerges

Flu activity has begun earlier than usual this year, with the first wave hitting the western United States instead of the typical southern start. The season kicked off weeks ahead of the normal schedule. Health officials note the shift in geography and timing is unusual. Scientists have identified a new flu variant carrying a mutation that lets it slip past existing immune defenses. The mutation may be helping the virus spread more easily and could be a factor in the early outbreak. ## Context Flu seasons normally start in the South and move northward as temperatures drop. An early start in the West suggests the virus is behaving differently, prompting closer monitoring of vaccine timing and public health response.
