Thonburi Trang

 A contagious Influenza A/B infection—faster onset and tougher than a common cold. Spreads via droplets and shared surfaces, especially during school season and cool/rainy months.

Common warning signs

• High fever with chills, marked fatigue

• Dry cough, sore throat, runny or blocked nose

• Headache and muscle aches

• Vomiting/diarrhea may occur in younger children

Red flags (see a doctor now)

• Fast or difficult breathing, chest retractions, bluish lips

• Fever >2–3 days, poor intake, unusual sleepiness

• Febrile seizure or persistent vomiting

• Age under 5 (esp. <2) or underlying conditions (asthma, heart/lung disease, immune problems)

Home care that matters

1. Fever control + rest (weight-based dosing as advised)

2. Hydration—small frequent sips; keep breastfeeding

3. Mask, isolate utensils, clean toys & surfaces

Antibiotics don’t treat flu. Clinicians may consider antivirals for high-risk kids if started early (~within 48 hours).

Prevention

• Hand hygiene, cough etiquette, stay home if feverish

• Annual influenza vaccination for everyone ≥6 months

  • First season for 6 months–8 years may require 2 doses (≥4 weeks apart)

  • Older children/adults: 1 dose each year

When to visit Thonburi Trang Hospital

• Any red flags or high-risk child

• Need assessment for antivirals, school note, or vaccine planning
  Services: Pediatric evaluation, oxygen check, tests/imaging when indicated, home-care plan, and annual flu vaccination

FAQs

How is flu different from a cold?
Faster onset, higher fever, stronger body aches, more exhaustion.

Do painkillers alone solve it?
They help comfort; some children benefit from antivirals—doctor will decide.

Best time for the flu shot?
Before the season peaks; but getting it anytime is better than skipping.

If my child had flu already, still vaccinate?
Yes—strains change and immunity wanes by next season.
