In Oregon, the flu has become increasingly active during the 2025-26 season, starting from a 0.4% positive increase and zero hospitalizations during the week of Sep. 28 to a 16.2% positive increase and 49 hospitalizations during the week of Jan. 11. Additionally, the 2025-26 Oregon flu season had the lowest amount of flu immunizations in the past four years. The amount of immunizations this year peaked at the end of September, drastically decreasing since then.
Influenza — or the flu — is an infection of the respiratory system primarily through the nose, throat and lungs. Symptoms for the flu can be similar to a common cold, such as the sore throat and runny or stuffy nose, but the flu amplifies these symptoms, and is often accompanied by additional symptoms like fever, cough, headache, muscle aches, exhaustion, sweating and chills. A cold tends to have a slow start, while the flu can come on very quickly, typically two to three days after contact with the virus.
Flu season in North America usually runs from October to May. The virus is spread through coughs, sneezes, spit and touch. To help prevent getting the flu, it is recommended to stay away from others who have it as well as to sanitize hands and surfaces frequently.
This flu season, about 15 million Americans have come down with the flu so far, and, as of Jan. 13, 180,000 have been admitted to the hospital with the flu, with 7,400 reported deaths.
This flu season, a variant of the flu called subclade K has been prevalent, thus being the cause of the rise in cases. The seasonal flu vaccine in the US this year provided protection against three flu viruses that researchers had expected to be the most common, but did not account for the sudden mutation of subclade K, making the vaccine less effective. The subclade K variant has not been present in the past few years, which also resulted in a natural decrease in immunity.
The subclade K variant has been responsible for 90% of flu cases this year. There is no evidence to suggest that the variant is more severe, just much more active due to its mutations.
Due to the sudden rise of the mutation, the flu vaccine this year is less effective. Typically, the vaccine is anywhere between 60-65% effective in the prevention of the flu, but this year the vaccine is only 30-40% effective. That being said, experts still recommend getting the vaccine to anyone who doesn’t have a medical reason not to because, not only does it reduce the risk of getting the flu, it also lessens the severity if anyone does get the flu. The flu vaccine takes about two weeks to be fully effective, so those who plan to get it should do so sooner rather than later.
Minor side effects that may arise from getting the flu shot include soreness, a low fever, aches and redness, along with swelling where the shot was given.
Walgreens offers a free flu shot for those who are interested. They take walk-ins, with the option to also schedule ahead. Walgreens recommends the flu shot for anyone three years old and up. Those who get it should also consider getting the vaccine once a year due to immunity fading over time as well as new variations arising yearly.
Any Western student who pays the health fee can also go to the Health and Counseling Center on campus to get their flu shot. Clinic hours are Monday through Friday, 9-12 p.m. and 1-5 p.m. They also offer free cold and flu kits to students that include medicine, thermometers and throat lozenges, among other things, to help stay healthy during flu season.
