What is RSV?
Respiratory Syncytial Virus (RSV) is a highly contagious virus. It affects the respiratory tract, including the nose, throat, and lungs. In fact, RSV is one of the leading causes of respiratory infections worldwide. It especially affects infants, older adults, and individuals with weakened immune systems.
While RSV often causes mild, cold-like symptoms, it can become serious. For example, it may progress into bronchiolitis or pneumonia. Sometimes, these conditions require hospitalization.
Global data shows that RSV causes millions of severe infections every year. This typically happens during colder or rainy seasons when viruses spread more easily.
How RSV Spreads
RSV spreads easily through:
- Through the Air – Droplets spread when an infected person coughs or sneezes.
- Through Touch – Direct contact spreads the virus. This includes touching someone’s hands, door handles, or shared surfaces contaminated with the virus.
- Through Proximity – A close proximity increases the risk, especially in crowded workplaces, classrooms, hospitals, and childcare centers.
Surface Survival – The virus can survive for hours on hard surfaces. Therefore, it becomes particularly infectious in shared spaces, which include offices, elevators, and clinics.
Contagious Period – Individuals infected with RSV are contagious for 3 to 8 days. However, infants and adults with weak immune systems can remain infectious for up to 4 weeks.
Symptoms of RSV Infection
RSV symptoms appear 4 to 6 days after exposure. Often, they resemble a common cold. As a result, people tend to underestimate the infection.
Typical symptoms include:
- Runny nose and nasal congestion
- Cough and sore throat
- Low-grade fever
- Fatigue or general weakness
- Headache or mild muscle pain
In Healthy Adults, RSV resolves in a week or two for healthy adults.
In High-Risk Groups However, symptoms can worsen in older adults, infants, or those with chronic illnesses. Therefore, watch for these warning signs:
- Shortness of breath or wheezing
- Persistent cough with mucus
- Chest pain or tightness
- Rapid breathing or difficulty breathing
When RSV Becomes Serious
RSV can progress into severe lower respiratory infections. This is particularly true for vulnerable groups.
Complications include:
- Bronchiolitis – inflammation and narrowing of the small airways in the lungs
- Pneumonia – lung infection that may require hospitalization
- COPD or Asthma Exacerbation – worsening of chronic respiratory conditions
- Otitis Media – ear infections, especially in children
- Respiratory Failure – rare, but potentially fatal in elderly or immunocompromised patients
Globally, RSV is recognized as a major cause of hospitalization among infants under 1 year old and older adults over 60 years, often rivaling influenza in severity during seasonal outbreaks.
Who is Most at Risk?
While anyone can get RSV, the following groups are most at risk for complications:
High-Risk Group | Why at Risk |
Infants & young children (<2 years) | Airways are small and more prone to blockage or inflammation |
Adults aged 60 and older | Weakened immune response and preexisting conditions |
People with chronic illnesses | Especially heart, lung, or immune system diseases |
Pregnant women and newborns | Infection can spread to the baby after birth |
Healthcare and eldercare workers | Frequent exposure to respiratory infections |
Employees in closed or air-conditioned offices | Prolonged indoor contact increases transmission |
RSV vs. the Common Cold and Flu
RSV is often mistaken for a cold or flu, but it behaves differently:
Characteristic | Common Cold | Influenza (Flu) | RSV |
Cause | Rhinoviruses | Influenza viruses (A/B) | Respiratory Syncytial Virus |
Onset | Gradual | Sudden | Gradual |
Main Symptoms | Runny nose, sore throat | High fever, body aches | Persistent cough, wheezing |
Common in | All ages | All ages | Infants, seniors, adults with chronic illness |
Severe Complications | Rare | Pneumonia, hospitalization | Bronchiolitis, pneumonia, COPD flare-ups |
Vaccine Available | None | Yes (Flu Vaccine) | Yes (RSV Vaccine – new) |
Workplace Impact of RSV
RSV can be diagnosed through:
- Increased Absenteeism – Infected employees may miss work for several days. In addition, parents may take leave to care for sick children.
- Spread Among Staff – The virus spreads quickly in offices, especially in air-conditioned work environments.
- Rising Healthcare Costs – Widespread infection can cause companies to face higher medical and HMO expenses.
- Business Disruption – Team productivity drops when multiple employees fall ill at once.
While RSV is self-limiting in most cases, early diagnosis in high-risk individuals allows prompt treatment and reduces complications.

Treatment
Currently, there is no specific antiviral cure for RSV in most adults. Treatment focuses on symptom management and supportive care, including:
- Adequate rest and hydration
- Fever and pain relief (paracetamol or ibuprofen)
- Use of humidifiers to ease breathing
- Supplemental oxygen or hospitalization for severe cases
For high-risk patients, healthcare providers may use monoclonal antibodies (e.g., nirsevimab or palivizumab) to reduce severe infection risk in infants, or administer RSV vaccines as preventive protection in adults.
Prevention: A New Era with RSV Vaccines
For many years, RSV prevention relied only on hygiene and infection control. However, the introduction of modern RSV vaccines has changed it.
Available RSV Vaccines Two new vaccines are now available internationally. Moreover, they are expected to reach the Philippines soon:
- Arexvy® (GSK) — for adults 60 years and older
- Abrysvo® (Pfizer) — for adults 60 years and older, and pregnant women (to protect infants through maternal antibodies)
Both vaccines have shown over 80% effectiveness in preventing severe RSV-related lower respiratory infections and reduce hospitalization rates among high-risk populations.
These vaccines mark the first major advancement in RSV prevention — protecting both older adults and infants through maternal immunization.
RSV and the Philippines
In tropical countries like the Philippines, RSV circulates year-round. However, it peaks during the rainy months (June to October).
- Hospital Impact – During this time, hospitals see an increase in admissions. Many cases involve bronchiolitis and pneumonia linked to RSV in the Philippines. These especially affect children.
- Company Impact – For companies, this seasonal rise means increased absenteeism. Parents take leave to care for sick children. Additionally, employees themselves fall ill.
- Prevention Benefits – Therefore, vaccination and awareness are essential. They benefit not only individual health but also organizational continuity and cost efficiency.
Cost-Benefit Perspective for Companies
While new vaccines may seem like an added expense, their benefits outweigh costs.
Key Benefits include:
- Reduced Absenteeism – It lowers the rate of employees missing work due to illness.
- Lower Healthcare Costs – Decrease hospitalization and HMO usage rates.
- Fewer Outbreaks – Contagion cycles in office settings are minimized.
- Enhanced Confidence – Employees will feel more confident in workplace health programs.
- Strategic Value – Companies that integrate RSV vaccination into annual wellness campaigns show commitment. This includes combining it with flu and pneumonia shots. As a result, they demonstrate dedication to employee well-being and resilience.
