What Is RSV and Where Did It Come From?
Respiratory Syncytial Virus (RSV) was first identified in 1956 in chimpanzees with cold-like symptoms and later detected in humans. Today, it’s one of the most common respiratory viruses, particularly affecting children under 5 and older adults.
Major Outbreaks
- In the U.S., RSV sends over 58,000 children to hospitals annually.
- In Thailand, RSV typically spreads during the rainy and cool season (July–December).
How Does RSV Spread?
RSV is highly contagious and spreads through:
- Droplets from coughs or sneezes of infected individuals
- Touching contaminated surfaces or toys
- Sharing utensils, cups, or towels
The virus can survive on hard surfaces for several hours, making hygiene crucial.
Incubation Period
Symptoms usually appear 2–8 days after exposure, and infected individuals can spread the virus before they even realize they’re sick.
Symptoms of RSV
Short-term (acute):
- Fever, cough, runny nose
- Wheezing or rapid breathing
- Poor feeding and fatigue in infants
Possible long-term effects:
- Increased risk of asthma later in life
- Frequent respiratory infections
- Premature babies may face higher risk of chronic lung disease
Treatment for RSV
There is no specific antiviral medication for RSV in most cases. Treatment focuses on symptom relief until recovery:
For mild cases:
- Plenty of rest
- Adequate hydration
- Fever control with lukewarm sponging
- Paracetamol for fever (avoid antibiotics—RSV is viral, not bacterial)
For severe cases:
- Oxygen therapy for breathing difficulties
- Suctioning mucus if airways are blocked
- IV fluids if dehydration occurs
- Hospitalization may be required in critical cases
High-risk infants (premature or with heart/lung conditions) may receive Palivizumab, an expensive preventive injection not widely available in Thailand.
How to Protect Yourself and Your Family
- Wash hands frequently
- Avoid crowded places for young children
- Separate sick children from healthy ones
- Clean toys and surfaces regularly
- Adults with symptoms should wear masks near children
Warning Signs: Seek Medical Help Immediately
- Rapid or labored breathing with chest retractions
- Wheezing sounds when breathing
- Bluish lips or face (cyanosis), cold hands and feet
- Refusal to feed, extreme fatigue
- Persistent high fever (lasting more than two days without improvement)
