1. Influenza (Flu)
2024-25 Flu Season
The flu started earlier than usual this season. Both Influenza A and B are circulating.
Cold vs. Flu
| Cold | Flu | |
|---|---|---|
| Onset | Gradual | Sudden |
| Fever | Low or none | High (102°F+ / 39°C+) |
| Body aches | Mild | Severe |
| Energy | Relatively normal | Very lethargic |
Flu Vaccine
- Eligible: 6 months and older
- First-timers: 2 doses, 4 weeks apart
- It's not too late to vaccinate even during flu season
Treatment
- Antivirals (like Tamiflu) work best within 48 hours of symptom onset
- See a doctor quickly if flu is suspected
- Fever reducers, fluids, and rest
2. RSV (Respiratory Syncytial Virus)
What is RSV?
A respiratory virus that peaks in winter through early spring. It can cause bronchiolitis or pneumonia in babies under 2 years.
High-Risk Groups
- Babies under 6 months
- Premature babies (born before 37 weeks)
- Babies with heart or lung conditions
- Immunocompromised babies
Symptoms
- Starts like a cold (runny nose, cough)
- Cough progressively worsens
- Wheezing when breathing
- Fast or labored breathing
- Refusal to feed, fussiness
Prevention
- Handwashing is most important!
- Avoid contact with sick people
- Avoid crowded places
- High-risk babies: consider Palivizumab (Synagis)
- New vaccines (Arexvy, Abrysvo) available for high-risk groups
3. Whooping Cough (Pertussis)
2024 Pertussis Outbreak - Record High Cases!
Whooping cough cases have surged dramatically in 2024. It's especially dangerous for infants under 6 months who haven't completed their DTaP series.
What is Whooping Cough?
A bacterial respiratory infection that can cause coughing fits lasting 100 days (about 3 months) - hence the name.
Symptoms (Stages)
| Stage | Duration | Symptoms |
|---|---|---|
| Catarrhal | 1-2 weeks | Cold-like symptoms (runny nose, mild cough) |
| Paroxysmal | 2-8 weeks | Coughing fits + "whoop" sound, vomiting, red face |
| Convalescent | Weeks to months | Gradual decrease in coughing |
Why It's Dangerous for Infants
- Apnea (stopping breathing) after coughing fits
- Cyanosis (turning blue)
- Can lead to brain damage or death in severe cases
- Infants may show only apnea without the characteristic "whoop"
DTaP Vaccine Schedule
- Primary series: 2, 4, 6 months
- Boosters: 15-18 months, 4-6 years
- Risk is highest before completing the primary series
Tip: Pregnant women getting Tdap during weeks 27-36 pass antibodies to protect newborns.
Seek Emergency Care If:
- Baby stops breathing or pauses after coughing
- Lips or face turn blue
- Baby becomes limp or unresponsive
4. Mycoplasma Pneumonia
What is Mycoplasma?
Mycoplasma pneumoniae is a type of bacteria causing "walking pneumonia." It has been spreading significantly since fall 2024.
Who Gets It?
- Most common in school-age children (5+)
- Younger babies are less likely to catch it, but can get severe cases
- Spreads through households with older siblings
Symptoms
- Persistent dry cough (most characteristic)
- Fever (100-102°F / 38-39°C)
- Headache, sore throat
- Fatigue
- Can progress to pneumonia
Note: If cough persists for 2-3+ weeks, consider testing for Mycoplasma.
Treatment
- Requires antibiotic treatment (usually macrolide antibiotics)
- Regular cold medicines won't help
- Cough may persist even after starting treatment - be patient
Prevention
- No vaccine available - hygiene practices are key
- Avoid contact with people who are coughing
- Good ventilation
5. Norovirus (Winter Stomach Bug)
What is Norovirus?
A major cause of winter gastroenteritis. Highly contagious and spreads easily within families.
Symptoms
- Sudden vomiting (often the first sign, and severe)
- Watery diarrhea
- Stomach cramps, nausea
- Low-grade fever
- Usually improves within 1-3 days
Watch for Dehydration!
Babies can become dehydrated quickly from vomiting and diarrhea.
- Offer oral rehydration solution (ORS)
- Continue breastfeeding/formula
- Small frequent sips rather than large amounts
See a Doctor If:
- No wet diaper for 6+ hours
- Dry lips, sunken eyes
- No tears when crying
- Blood in stool or vomit
- High fever
Prevention
- Handwashing with soap (alcohol sanitizers less effective against norovirus)
- Cook food thoroughly
- Use gloves when cleaning up vomit/diarrhea
- Disinfect with bleach solution (1:50 dilution)

FAQ
Q. Can my baby have multiple illnesses at once?
Yes, it's not uncommon. Flu + bacterial infection together can make things worse. Watch for worsening symptoms.
Q. Can vaccinated children still get whooping cough?
Vaccine protection wanes over time. But vaccinated children usually have milder cases.
Q. What if we missed some vaccinations?
It's better late than never! Your pediatrician can create a catch-up schedule.
