Respiratory Syncytial Virus (RSV)

Respiratory Syncytial Virus (RSV) is a common and highly contagious virus that affects people of all ages, but it most severely affects young children and older adults. It is the leading cause of lower respiratory tract infections in infants and young children worldwide.

What is RSV?

RSV is a member of the Pneumoviridae family of viruses and is spread through contact with infected individuals, contaminated surfaces, or airborne droplets. The virus infects cells in the respiratory tract, causing inflammation and damage to the airways.

Symptoms of RSV

The symptoms of RSV infection can range from mild to severe and may include:

• Runny nose and congestion
• Coughing and sneezing
• Fever
• Loss of appetite
• Wheezing or difficulty breathing
• Apnea (pauses in breathing) in infants
• Bronchiolitis (inflammation of the small airways) and pneumonia in severe cases

Risk Factors for Severe RSV Infection

Certain individuals are at higher risk for developing severe RSV infection, including:

• Infants under 6 months old
• Premature infants
• Children with underlying health conditions, such as heart disease or lung disease
• Older adults, especially those with weakened immune systems
• People with compromised immune systems, such as those with HIV/AIDS or undergoing chemotherapy

Treatments for RSV

There is no specific treatment for RSV infection, but symptoms can be managed with:

• Supportive care, such as rest, hydration, and nutrition
• Over-the-counter medications to relieve fever and congestion
• Oxygen therapy to help with breathing difficulties
• Antibiotics may be prescribed if a secondary bacterial infection develops
• Hospitalization may be necessary for severe cases, especially in high-risk individuals

Prevention of RSV

To reduce the risk of RSV transmission:

• Practice good hygiene, such as frequent handwashing and proper disposal of contaminated materials
• Avoid close contact with infected individuals
• Clean and disinfect surfaces regularly
• Avoid sharing utensils, glasses, or other personal items
• Get vaccinated against RSV, if available (e.g., palivizumab for high-risk infants)

Complications of RSV

In severe cases, RSV infection can lead to complications such as:

• Bronchiolitis and pneumonia
• Asthma and wheezing
• Respiratory failure
• Cardiac problems, such as heart failure or arrhythmias
• Neurological problems, such as seizures or encephalitis

Diagnosis of RSV

RSV infection can be diagnosed through:

• Physical examination and medical history
• Laboratory tests, such as rapid antigen detection or polymerase chain reaction (PCR)
• Chest X-rays to evaluate lung involvement
