Flu Season Started Early This Year: What Denton Families Need to Know

Reviewed by the Evolve Health clinical team · 2026-10-16 · 5 min read

Most years, flu waits until December to really get going. This year it did not wait. National tracking shows flu activity rising since late August, and Texas health officials opened the season with an unusually early push for vaccination. Nobody needs to panic over numbers that are still low overall — but "plenty of time" is the one thing this season is not offering. Here is what is happening, what it means for North Texas, and the handful of decisions worth making now.

What's happening with flu this year

The CDC's first FluView report of the 2026–27 season, covering the week ending October 10, tells the story in a few numbers:

• Test positivity jumped from 3.9% to 5% in one week — a 28% rise, and a level usually not seen until much later in the fall.
• Flu hospital admissions nearly tripled in a month, from 1,133 in the week ending September 5 to 3,334 in the week ending October 3.
• One strain is dominating: influenza A(H1N1) accounts for 96.4% of subtyped influenza A samples so far.
• Older adults are being hit hardest, with an admission rate of 3.8 per 100,000 for people 65 and older — the highest of any age group — followed by children under 5.

USA TODAY reported on October 13 that wastewater monitoring shows the earliest flu season onset in at least four years, with flu infections rising in all 50 states and activity at levels more typical of December or January. A Texas infectious-disease clinician quoted in that coverage described influenza A increasing over the first two weeks of October and called the early start unusual. The honest summary: flu activity is still low in absolute terms, but it is rising earlier and faster than a normal year — which is exactly when getting vaccinated pays off most.

What this means for Texas and Denton

Texas is not watching from the sidelines. The Texas Department of State Health Services (DSHS) marked October 1 as Texas Influenza Awareness Day and is urging every Texan 6 months and older to get a flu shot as soon as possible. Federal tracking for HHS Region 6 — the region that includes Texas — also showed flu test positivity rising in the week ending October 10.

To be clear about what we are and are not saying: no one is reporting a Denton outbreak. What the Texas and national numbers do show is a season starting early across the state and country, which means Denton families get the most benefit by doing in October what usually waits until November — flu shots before holiday travel, and a plan for what to do if symptoms start. Classrooms, dorms, youth sports, and multigenerational households are where flu moves fastest, and they are everyday life here.

Flu vs. cold vs. COVID: how to tell them apart

The fastest way to sort it out is how it starts. Flu tends to hit all at once — fever, aches, and exhaustion within hours. A cold builds slowly and stays above the neck. COVID overlaps with both, which is why testing matters when it changes what you do next.

Who should get the flu shot first

Everyone 6 months and older should get a flu shot this season — that is the shared recommendation of Texas DSHS and the major medical groups. But if your household is scheduling in waves, these family members go first, because this year's early data already shows who flu is sending to the hospital:

• Adults 65 and older — the highest flu admission rate right now. Ask about the enhanced flu vaccines made for older adults.
• Children under 5 — the second-highest admission rate, and young kids have less immune experience with flu.
• Pregnant patients — the shot protects you during pregnancy and passes protection to your baby for their first months.
• Anyone with a chronic condition — asthma, diabetes, heart or lung disease, or a weakened immune system makes flu complications more likely.
• First-time flu shots for kids under 9: children in this group need two doses, four weeks apart. Starting now means both doses are done before the holidays.

When to get it: now, and here's the math

A flu shot takes about two weeks to protect you — your body needs that time to build antibodies. Work backwards from Thanksgiving: a shot this week in October means full protection well before holiday travel, visiting grandparents, and crowded gatherings. That timing is the whole story this year. If you are searching for a flu shot near me or a walk-in flu shot in Denton, sooner genuinely is better — and a November shot still helps, because flu will be circulating for months. It is not too late until the season is over; it is just a little less early.

Already sick? The 48-hour window matters

If flu symptoms have already started, speed matters more than it does with a cold. Antiviral medicines work best when started within 48 hours of your first symptoms — they can shorten the illness and lower the risk of complications, especially for the higher-risk groups above. That window is why a rapid flu test in Denton, done the day you feel sick, is worth the trip: it confirms flu while an antiviral can still help, and your clinician can prescribe during the same visit if it is right for you.

Most flu can be cared for at home with rest, fluids, and fever reducers. Get care the same day — or urgent help right away — if you notice:

• Difficulty breathing or shortness of breath
• Chest pain or pressure
• Confusion, dizziness, or trouble waking up
• Signs of dehydration — very little urine, extreme thirst, dry mouth
• Fever or cough that improves, then returns or gets worse
• In children: fast or labored breathing, bluish lips, severe irritability, or fever in an infant under 3 months

Flu and COVID shots at the same visit

Yes, you can do both in one trip. Flu and COVID shots can be given at the same visit, which makes fall vaccination a single stop instead of two. This year that convenience matters a little more: with national vaccine guidance in the headlines, four major medical groups — family physicians, pediatricians, OB-GYNs, and infectious-disease specialists — issued their own fall recommendations, and all of them agree on the flu shot for everyone 6 months and older. If you are unsure which shots your family needs this fall, bring your questions to your visit and we will sort it out together.

Frequently asked questions

Is flu season starting early in 2026?

Yes. The CDC's first FluView report of the 2026–27 season showed flu test positivity climbing from 3.9% to 5% in a single week, and wastewater data suggests the earliest flu season onset in at least four years. Flu is rising in all 50 states — months ahead of the usual December–February peak.

When should I get my flu shot in 2026?

Now. Texas DSHS and the CDC both urge everyone 6 months and older to get vaccinated as soon as possible, ideally by the end of October. Because the shot takes about two weeks to protect you, an October shot has you covered before Thanksgiving travel and holiday gatherings. A shot in November still helps — flu circulates for months — but earlier is better this year.

How long does the flu shot take to work?

About two weeks. Your body needs roughly 14 days after the shot to build up antibodies, which is why timing matters when flu is already circulating. Getting vaccinated this week means real protection by the time holiday travel begins.

How long after flu symptoms start does Tamiflu work?

Antiviral medicines such as Tamiflu (oseltamivir) work best when started within 48 hours of your first symptoms — the sooner, the better. That is why a rapid flu test early on matters: it confirms flu while there is still time for an antiviral to help. If you are in a higher-risk group, call a clinician the day symptoms start rather than waiting it out.

Can I get the flu shot and COVID shot at the same visit?

Yes — flu and COVID shots can be given at the same visit, one in each arm or in the same arm at different spots. It is a convenient way to get both done in one trip. Ask our team what is right for you and your family at your visit.

Does my child need two flu shots this year?

Possibly. Children under 9 who are getting a flu vaccine for the first time need two doses, given at least four weeks apart, for full protection. Starting in October means both doses are done before the holidays. Children who have had flu shots in past seasons generally need just one dose — ask us and we will check your child's record.
