RSV – A comprehensive introduction to respiratory syncytial virus (RSV)

Respiratory syncytial virus (RSV) is a common virus that primarily infects the upper and lower respiratory tract. It is a common cause of respiratory infections in infants, young children, older adults and people with weakened immune systems. RSV was first discovered in the 1950s and has since become a major health problem worldwide.

What is RSV?

RSV belongs to the paramyxovirus family and the pneumovirus subfamily. It is an RNA virus that spreads through the air and replicates mainly in the mucous membranes of the respiratory tract. It can cause both upper and lower respiratory infections, from mild cold symptoms to severe pneumonia.

How does RSV spread?

RSV is highly contagious and spreads from person to person through respiratory droplets. Coughing, sneezing and direct contact with infected people or contaminated surfaces can lead to transmission of the virus. The peak of RSV infections occurs in the winter months, with infants and young children at particular risk.

Symptoms of RSV infections

The symptoms of an RSV infection are often similar to those of a cold. They can cause symptoms such as cough, runny nose, fever, sore throat and headache. In infants and young children, RSV can also cause bronchiolitis, an inflammation of the small airways in the lungs. Severe cases of RSV can cause shortness of breath, cyanosis (blue discoloration of the skin), and in rare cases, death.

Diagnosis of RSV infections

The diagnosis of RSV infection is usually based on clinical symptoms and can be confirmed by various tests. A commonly performed test is the nasal swab, which takes samples of nasal secretions to detect the virus. In some cases, a blood test may also be done to detect antibodies to RSV.

Treatment of RSV infections

There is no specific antiviral treatment for RSV infections. In most cases, symptoms are treated with supportive measures. These include rest, adequate fluid intake, decongestant nasal drops and fever-reducing medication. Severe cases of RSV, particularly in infants and young children, may require hospitalization to provide appropriate care.

Prevention of RSV infections

Prevention of RSV infections focuses primarily on hygiene measures. These include washing your hands regularly, avoiding crowds during RSV season, keeping your distance from infected people, and using disinfectants on surfaces. RSV vaccination is currently only available for certain high-risk groups, such as premature babies.

RSV in infants and young children

RSV infections are particularly common in infants and young children. They are at higher risk of serious complications because their respiratory and immune systems are not yet fully developed. Parents and caregivers should pay particular attention to symptoms of RSV and seek medical advice quickly if infection is suspected.

RSV in older adults and people with weakened immune systems

Although RSV is primarily known to occur in children, older adults and people with weakened immune systems can also be susceptible to serious RSV infections. This is especially true for people with chronic lung disease, cardiovascular disease, or a history of smoking.

Conclusion:

Respiratory syncytial virus (RSV) is a common virus that can cause respiratory infections. It mainly affects infants, young children, older adults and people with weakened immune systems. Although most cases are mild and recover on their own, severe cases of RSV can lead to pneumonia and other complications. Prevention of RSV infections through hygiene measures is of great importance, especially for people at risk. Early diagnosis and appropriate care can help prevent serious complications.
