West Coast sees unusually early rise in flu cases, doctors urge vaccination

Health officials report that the United States is entering flu season earlier than usual, with the Pacific Northwest and California experiencing a notable increase in cases. Dr. Helen Chu, a respiratory infections specialist at the University of Washington, said the region is seeing a "very, very early" surge of flu A, contrary to the typical pattern where flu spreads northward from the South and Southeast.

Johns Hopkins professor Dr. Andrew Pekosz explained that the current wave is dominated by the H1N1 strain, which may spread more easily and evade existing immunity. While the exact impact on the overall season remains uncertain, both doctors emphasized that vaccination remains the most effective preventive measure.

"I think it probably makes sense to get vaccinated a little bit earlier this year," Chu said. Columbia University physician Dr. Kaylan Christianer added that the vaccine takes about two weeks to become fully effective and urged people not to wait for a perfect match. The vaccine is recommended for everyone six months and older, with high-dose and mRNA options available for older adults, and a nasal spray option for those who prefer a needle-free delivery.

In addition to vaccination, doctors highlighted standard hygiene practices such as hand washing, mask use in crowded settings, and staying home when ill to reduce transmission. They noted that declining vaccine uptake may be contributing to the severity of recent flu seasons.

Public health authorities advise monitoring local health department updates to stay informed about regional flu activity and to adjust protective behaviors accordingly.
