Respiratory syncytial virus, commonly known as RSV, is one of the many viruses responsible for infections of the ear, nose, throat, and lungs. This pervasive virus affects people of all age groups and is found worldwide. Fortunately, you can learn everything you need to know about RSV with a search online right now, which could help you spot early symptoms.
Who’s Vulnerable to RSV?
RSV poses a significant threat to children under two years of age, ranking as the leading cause of hospitalizations among infants under one year old in developed nations. Premature infants, adults aged 65 and older, and individuals with chronic heart and lung conditions face an elevated risk of severe illness and hospitalization.
RSV infections are a year-round concern, with a notable increase in cases during the late fall to early spring in North America. The precise onset and conclusion of RSV season vary slightly each year, with infections peaking during January and February. RSV infections typically follow a two-year cycle, alternating between high numbers and increased severity one year and milder cases the next.
While most children experience at least one RSV infection by the age of two, previous infections do not provide long-lasting immunity. Antibodies produced by the immune system in response to RSV infection typically last only six to 12 months, necessitating repeated exposure to maintain high antibody levels. This cycle explains the alternating pattern of severe and mild RSV infections.
How RSV Spreads
RSV transmission occurs through two primary means:
- Contact with objects contaminated by respiratory secretions from an infected person. When the individual touches their nose or mouth, the germs on their hands can lead to their own infection.
- Inhalation of the virus when an infected person coughs or sneezes within close proximity (one meter) without covering their nose or mouth.
Recognizing RSV Symptoms
RSV symptoms typically appear three to seven days after infection and resemble those of a common cold, including fever, runny or congested nose, sore throat, cough, and decreased energy. Muscle aches and decreased appetite may also be present. Some individuals may experience breathing difficulties. Notably, RSV symptoms closely mimic those of other respiratory viruses.
Treatment for RSV
As RSV is a viral infection, antibiotics are ineffective in shortening its duration or reducing its contagiousness. No antiviral medications are available for treating RSV infections. Most patients can manage their symptoms at home:
- Use antipyretics (fever-reducing medications) if fever is present, although this does not shorten the illness.
- Saline sprays or drops help relieve nasal congestion and can be used frequently without risk of overdose.
- Commercially available nasal aspirators can aid infants and children in breathing more comfortably.
- Encourage fluid intake to prevent dehydration, offering small amounts regularly. For infants, breastmilk or formula is suitable, while older children can consume a variety of fluids, including oral rehydration solutions, broths, popsicles, ice cream, and gelatin. Extended periods of consuming only water should be avoided.
When to Seek Emergency Care for RSV in Children
While most RSV cases can be managed at home, certain circumstances warrant medical attention:
- Rapid or labored breathing, even without fever.
- Significant reduction in feeding among infants.
- Excessive sleepiness or difficulty in waking.
- No urination in 12 hours.
Hospitalization may be necessary for RSV-infected patients requiring:
- Supplementary oxygen.
- Intravenous fluids due to dehydration.
Protecting Against RSV
Although no vaccines are available for RSV, a specially prepared antibody called palivizumab is recommended to reduce complications in premature infants and children with chronic heart or lung conditions who meet specific criteria. Palivizumab is administered as monthly injections during the RSV season.
Adhering to the same preventive measures effective against COVID-19 and other respiratory viruses reduces the risk of RSV infection:
- Frequent and thorough handwashing.
- Maintaining a two-meter distance from others in public settings, as RSV-infected individuals can transmit the virus before showing symptoms.
- Wearing masks in enclosed public spaces.
To protect others:
- Stay home from school or work when sick.
- Practice cough etiquette by covering your mouth and nose with your elbow or a tissue to prevent virus transmission.
By following these guidelines, we can collectively reduce the risk of RSV infection and help safeguard our communities.
