Flu season is here, and this year, it’s proving to be one of the most severe in recent history. With increasing flu cases, overwhelmed hospitals, and an aggressive strain circulating, parents must take extra precautions to protect their children. This guide will help you understand how flu in New Jersey affects families, recognize symptoms early, and take the proper steps to keep your household safe.
When Is Flu Season in NJ?
Flu season in New Jersey typically starts in October and lasts until May, with peak activity between late December and early March. However, in 2025, cases began surging earlier than expected, and health officials predict that flu activity will remain high through March and possibly into April. This makes early prevention more important than ever.
How Serious Is the Flu in New Jersey This Year?
This flu season has been one of the worst in over a decade. Here are the latest statistics:
- 29 million flu cases have been reported nationwide.
- 370,000 hospitalizations have occurred.
- 16,000 flu-related deaths, including 68 children, have been recorded.
- New Jersey is one of the hardest-hit states, with 20 flu-related deaths per week.
With schools reporting high absentee rates due to flu outbreaks, it’s clear that children are among the most vulnerable. Taking preventive measures is crucial.
Why Is the Flu Worse This Year?
Several factors have contributed to the severity of flu in New Jersey this season:
- A stronger flu strain – This year’s dominant strain is more aggressive, leading to severe symptoms.
- Lower vaccination rates – Misinformation and vaccine hesitancy have led to fewer people getting the flu shot.
- Weakened immunity – After years of COVID-19 precautions, children have had less exposure to seasonal viruses, making them more susceptible.
- Holiday gatherings and travel – Increased social interactions during the holidays contributed to the rapid spread of the virus.
How Effective Is the Flu Vaccine in 2025?
One of the biggest concerns for parents is whether the flu vaccine actually works. According to the Centers for Disease Control and Prevention (CDC), flu vaccines are updated each year to match the most common circulating strains. For the 2025 season, preliminary data suggests that the flu vaccine is 50–60% effective in preventing severe illness.
Even if a vaccinated person catches the flu, their symptoms tend to be milder and last for a shorter period compared to those who are unvaccinated.
Dr. Hisham Gadallah, MD, Pediatric Specialist, explains:
“This flu season has been particularly severe, especially among unvaccinated children. The flu vaccine remains the best defense, significantly reducing the risk of complications, particularly in young children and those with chronic conditions. Additionally, maintaining good hygiene and a balanced diet strengthens the immune system, offering extra protection against the virus.”
Is the flu vaccine safe for kids?
Yes, the flu vaccine is safe for children. The American Academy of Pediatrics (AAP) and the CDC recommend flu shots for all children aged 6 months and older. The vaccine undergoes extensive testing each year to ensure its safety and effectiveness. Side effects, if any, are usually mild and temporary, such as:
- Soreness at the injection site
- Low-grade fever
- Fatigue or mild aches
Flu Symptoms in Children: What to Watch For
Flu symptoms can develop quickly and are often mistaken for a common cold. The most common signs include:
- High fever (above 100°F)
- Chills and body aches
- Severe fatigue and weakness
- Persistent cough and sore throat
- Runny or stuffy nose
- Vomiting or diarrhea (more common in younger children)
When to Seek Medical Help
Most children recover from the flu with rest and proper care, but in some cases, medical attention is needed. Call a doctor if your child has:
- Difficulty breathing or rapid breathing
- Persistent high fever that doesn’t respond to medication
- Chest pain
- Confusion or difficulty staying awake
- Severe dehydration (no urination for 8+ hours, dry mouth, no tears when crying)
How to Prevent the Flu in New Jersey
Prevention is the best way to keep your child safe. Here’s how you can reduce the risk of flu infection:
1. Get the Flu Vaccine
The flu shot remains the most effective way to prevent serious illness. When well-matched to circulating flu strains, it can reduce the risk of severe complications by 40-60%. Even if your child contracts the flu after vaccination, symptoms are likely to be milder.
2. Teach Good Hygiene Habits
- Encourage frequent handwashing with soap and water for at least 20 seconds.
- Teach children to cough or sneeze into their elbows instead of their hands.
- Regularly sanitize frequently touched objects like toys, doorknobs, and electronic devices.
3. Avoid Crowded Public Spaces
Flu spreads quickly in schools, daycare centers, and indoor public places. If flu cases are rising in your community, limit unnecessary exposure to crowded areas.
4. Keep Sick Children at Home
If your child shows flu symptoms, keep them at home to prevent spreading the virus. Wait at least 24 hours after their fever goes down (without medication) before sending them back to school.
5. Strengthen Their Immune System
A strong immune system can help fight off infections. Support your child’s health by:
- Ensuring they get 8-10 hours of sleep per night.
- Providing a balanced diet rich in vitamins and minerals.
- Keeping them hydrated with water and nutritious fluids.
What to Do If Your Child Gets the Flu
If your child gets the flu, early treatment can help speed up recovery and prevent complications.
How to Care for a Sick Child at Home
- Encourage rest – Sleep is essential for recovery.
- Keep them hydrated – Offer water, clear soups, and electrolyte drinks.
- Use fever reducers – Medications like acetaminophen (Tylenol) or ibuprofen (Advil) can help with fever and body aches.
- Offer light meals – Foods like soup, oatmeal, and fruit are easier to digest.
When to Consider Antiviral Medication
If your child is at high risk for flu complications, a doctor may prescribe an antiviral medication like Tamiflu. These medications work best when taken within the first 48 hours of flu symptoms and can reduce the severity and duration of illness.
How Long Will the Flu Season Last?
Flu cases are expected to remain high through March, with a gradual decline in April. However, health officials warn that if vaccination rates remain low, the season could last longer than usual.
Final Thoughts: How Parents Can Stay Prepared
This year’s flu season is particularly severe, but by staying informed and taking the right precautions, you can protect your child from serious illness. Flu vaccinations, vaccines and immunization, along with good hygiene and a strong immune system, are essential to keeping your family safe.
If your child does get sick, monitor their symptoms closely and seek medical care if necessary. Flu prevention starts at home—take action today to ensure your family stays healthy throughout the season.
