Bronchiolitis on the Rise: Intensifying Flu Vaccination Efforts to Combat Respiratory Illnesses

Respiratory Illnesses Rise Across France: Bronchiolitis Epidemic Declared

October 31, 2025

Paris, France – public Health France has officially declared an epidemic of bronchiolitis in the Île-de-France region, marking the first area of the country to reach this stage. Data released on October 29th indicates a considerable increase in bronchiolitis cases, mirroring levels observed during the same period last year. Normandy is closely following, poised to enter the pre-epidemic phase for a third consecutive week, with other regions anticipated to be affected in the coming weeks.

Protecting Infants: Vaccination Strategies

Efforts to safeguard infants against respiratory syncytial virus (RSV), a major cause of bronchiolitis, began with a preventative campaign launched on September 1st. Two key approaches are available: vaccination for pregnant women with Abrysvo, which offers protection to newborns up to six months old, and passive immunization for newborns utilizing a monoclonal antibody known as Beyfortus.

Expanded Vaccine Access for Seniors

The High Authority for Health (HAS) has approved reimbursement for anti-RSV vaccinations – Abrysvo, Arexvy, and mResvia – for individuals aged 75 and older. Reimbursement is also available for those aged 65 and over with underlying cardiorespiratory conditions. However, the financial support for these vaccines is still pending implementation.

Flu and COVID-19 Updates

While bronchiolitis dominates current concerns, influenza and COVID-19 are also monitored closely. Flu indicators remain at basic levels throughout all French regions, but the annual vaccination campaign for at-risk populations – those over 65, peopel with chronic illnesses, immunocompromised individuals, and pregnant women – started in mid-October. Individuals under 65 without specific health concerns can also receive a flu vaccine, although it is not reimbursed and costs approximately 10 euros. The use of adjuvanted (Fluad) or high-dose (Efluelda) vaccines is now available for those over 65.

COVID-19 activity is currently declining in urban areas, with hospitalizations remaining stable and wastewater indicators showing a downward trend. The current COVID-19 vaccination campaign prioritizes those over 65, individuals at heightened risk, pregnant women, residents of nursing facilities, and those in close contact with vulnerable populations, including healthcare professionals.

Illness	Current Status	Key Preventative Measures
Bronchiolitis	Epidemic in Île-de-France	RSV vaccination for pregnant women, passive immunization for newborns
Influenza	Basic levels nationally	Annual vaccination campaign, particularly for at-risk groups
COVID-19	Declining activity	Vaccination campaign targeting vulnerable populations

Did You Know? Vaccination coverage amongst healthcare workers in nursing homes remains low, with only 21% vaccinated against influenza in 2024-2025, highlighting the need for improved uptake.

Pro Tip: Staying up-to-date with vaccinations is the most effective way to protect yourself and vulnerable populations from respiratory illnesses.

The debate surrounding mandatory influenza vaccination for healthcare workers continues, with the proposal included in the 2026 Social Security Financing Bill (PLFSS). A proposal from the HAS is required before implementation, and the authority is expected to provide its assessment in the first quarter of 2026.

Understanding Respiratory Illnesses

Respiratory syncytial virus (RSV) is a common respiratory virus that usually causes mild, cold-like symptoms. Though, RSV can be serious, especially for infants and older adults. Influenza, commonly known as the flu, is caused by influenza viruses that infect the nose, throat, and lungs. COVID-19,caused by the SARS-CoV-2 virus,continues to evolve,with ongoing monitoring of new variants. These viruses spread primarily through respiratory droplets produced when an infected person coughs or sneezes.

Frequently Asked Questions about Respiratory Illnesses

• What is bronchiolitis? Bronchiolitis is an infection of the small airways in the lungs, commonly affecting young children.
• who is at risk of severe RSV infection? Infants, older adults, and people with weakened immune systems are most vulnerable.
• Are flu vaccines effective? Flu vaccines are designed to protect against the influenza viruses that are expected to be most common during the season.
• What are the symptoms of COVID-19? Symptoms can range from mild cold-like symptoms to severe respiratory illness.
• Is the flu vaccine reimbursed in France? The flu vaccine is reimbursed for at-risk populations, but may require out-of-pocket payment for others.
• What steps can I take to prevent the spread of respiratory illnesses? Frequent handwashing, covering coughs and sneezes, and staying home when sick are crucial.

How does the current surge in bronchiolitis cases relate to post-pandemic immunity levels?

Understanding the Current Surge in Bronchiolitis Cases

Across the nation, we’re seeing a meaningful increase in bronchiolitis cases, particularly affecting infants and young children. This respiratory infection, most commonly caused by the Respiratory Syncytial Virus (RSV), inflames the small airways in the lungs – the bronchioles. The recent surge is attributed to a combination of factors, including waning immunity post-pandemic and increased social mixing. Early detection and preventative measures, including robust flu vaccination programs, are crucial in mitigating the impact. Understanding bronchiolitis symptoms is the first step in protecting your family.

RSV vs.Flu: Differentiating the Viruses & Shared Risks

While both RSV and influenza (the flu) are respiratory viruses, they present differently and impact individuals uniquely.

* RSV (Respiratory Syncytial Virus): Primarily affects young children under two years old. Symptoms frequently enough start like a common cold – runny nose, decreased appetite, cough – but can progress to wheezing, rapid breathing, and difficulty feeding. Severe cases may require hospitalization.

* Influenza (Flu): Can affect people of all ages.Symptoms are typically more abrupt and include fever, body aches, fatigue, cough, and sore throat. While less common, the flu can also lead to serious complications like pneumonia.

both viruses share similar transmission routes – through respiratory droplets produced when an infected person coughs or sneezes. This overlap highlights the importance of preventative measures like hand hygiene and, critically, annual flu shots. Co-infection with RSV and the flu is also possible, leading to more severe illness.

The Role of Flu Vaccination in Bronchiolitis Prevention

While there isn’t a vaccine specifically for RSV (though research is ongoing), flu vaccination plays a vital role in reducing the overall burden on the healthcare system and potentially lessening the severity of bronchiolitis cases. Here’s how:

1. Reduced Flu Cases: Fewer flu cases mean fewer hospitalizations, freeing up resources for children battling bronchiolitis.
2. Preventing Co-infection: Vaccination against the flu reduces the risk of a child being infected with both RSV and the flu simultaneously, which, as mentioned, can lead to more severe outcomes.
3. Protecting Vulnerable Populations: Vaccinating family members and caregivers helps create a “cocoon” of protection around infants too young to be vaccinated against the flu.
4. Strengthened immune Systems: Even if a vaccinated individual contracts the flu, the illness is typically milder, reducing the strain on the immune system and potentially lessening the risk of secondary infections.

Who Should Get Vaccinated? flu Vaccine Recommendations

The CDC recommends annual flu vaccination for everyone 6 months and older. Specific recommendations include:

* Infants and Children: children 6 months to 8 years old need two doses of the flu vaccine, spaced at least four weeks apart, the first time they are vaccinated.

* Pregnant Women: Flu vaccination is especially important during pregnancy, as it protects both the mother and the developing baby.

* Older Adults: Individuals 65 years and older are at higher risk of complications from the flu and should receive a high-dose flu vaccine.

* Individuals with Chronic Health Conditions: people with asthma,diabetes,heart disease,or other chronic conditions are more vulnerable to severe flu complications and should be vaccinated.

* Healthcare Workers: Protecting healthcare workers ensures they can continue to provide care to patients during flu season.

Recognizing Bronchiolitis Symptoms: When to Seek Medical attention

Early intervention is key to managing bronchiolitis. Be vigilant for these bronchiolitis symptoms:

* Initial Symptoms: Runny nose, mild cough, fever.

* Progressive Symptoms: Wheezing, rapid breathing (respiratory distress), difficulty feeding, lethargy, nasal flaring (nostrils widening with each breath), retractions (skin pulling in between the ribs or above the collarbone).

Seek immediate medical attention if your child exhibits any of the following:

* Difficulty breathing

* Blueish tint to the lips or fingernails (cyanosis)

* High fever (over 100.4°F / 38°C)

* Severe lethargy or unresponsiveness

* Dehydration (decreased urination, dry mouth)

Supportive Care at Home: Managing Mild Bronchiolitis

for mild cases of bronchiolitis, supportive care at home can definitely help manage symptoms:

* hydration: Offer frequent, small amounts of fluids.

* Nasal suction: gently suction nasal passages to clear
