The countdown to Christmas is a critical time to shield your family from the flu—and the stakes are rising. As illness numbers climb, experts are sharing practical steps to keep kids and loved ones healthier during the holiday season.
Recent CDC data covering the week ending December 6 show nearly 3 million confirmed flu cases across the United States, with about 30,000 hospitalizations and 1,200 deaths already this season. Health officials warn that case counts are likely to increase as holidays approach. Regions nationwide, including Colorado, Louisiana, and New York, are reporting higher activity, and some schools have begun remote learning or early dismissals to curb spread. In Dexter, Kansas, for example, the local school system opted for an early winter break after a substantial portion of students were out sick.
A key question this season is: what is the dominant flu variant circulating now? The leading strain is a new subclade known as K. This variant, a branch of the H3N2 family, has been spreading abroad since the summer and is now contributing to rising case numbers in several countries, including the United Kingdom. While it’s not an exact match to this year’s flu vaccine, health experts—including doctors and the CDC—still strongly advise vaccination for everyone aged six months and older as a protective measure. Young children who have not previously been vaccinated may need two doses, spaced at least four weeks apart.
The flu can present with a range of symptoms. Most commonly, people experience fever, chills, cough, sore throat, nasal symptoms, muscle aches, headaches, fatigue, and sometimes vomiting or diarrhea. Children are more likely to have gastrointestinal symptoms than adults. Understanding these signs can help families act quickly.
Vaccination remains a cornerstone of protection. Independent studies, including data from the U.K., suggest vaccines can substantially reduce severe outcomes: significant reductions in hospitalizations for children and meaningful protection for adults. It typically takes about two weeks after vaccination for antibodies to build up, so getting vaccinated ahead of travel or family gatherings is wise.
Travel during flu season adds additional considerations. The holiday period usually sees a surge in travel—tipping off around 122 million Americans hitting roads and skies between December 20 and January 1. To stay healthier on the move, consider these practical tips:
- Use touch-free security lanes where available to minimize contact with surfaces. Check if options like TSA PreCheck Touchless ID are available to you.
- Bring disinfecting wipes to clean high-touch areas such as armrests, tray tables, seat belts, touchscreens, and air vents.
- Practice thorough hand hygiene. Wash hands with soap and water for at least 20 seconds whenever possible; when not, use an alcohol-based sanitizer with at least 60% alcohol.
- Pack extra masks and wear them during travel, replacing them if they become damp or soiled.
- If you feel unwell, wear a mask and consider postponing travel until you’ve recovered.
These steps can significantly reduce your risk and help protect not only your household but also the broader traveling community this holiday season. What are your thoughts on the new subclade K?
