RSV

RSV stands for Respiratory Syncytial Virus. This virus is highly contagious and often leads to colds or flu-like illnesses during the cold winter months. It infects the respiratory tract and causes symptoms such as a runny nose, cough, fever, fatigue, and often conjunctivitis. The most common complication, particularly in infants and young children, is inflammation of the lower respiratory tract. RSV infections are often indistinguishable from other flu-like illnesses or COVID-19 because the symptoms are very similar. If there are breathing difficulties, persistent high fever, or if a baby refuses to drink, medical attention should be sought immediately. RSV infections do not provide lasting immunity, so reinfections can occur. However, individuals without specific risk factors usually recover well.

For infants and young children
To protect the youngest ones from RSV, it is recommended to avoid contact with individuals showing symptoms of respiratory infections. Additionally, there is a new passive immunization for infants using the monoclonal antibody Nirsevimab (Beyfortus®). This immunization is recommended for all infants at the start of their first RSV season. Ideally, the immunization should be administered in autumn (October) or, for winter births, as early as possible. The costs are covered by mandatory health insurance.

For adults aged 60 and older
Since this year, two RSV vaccines - Arexvy® and Abrysvo® - have been approved in Switzerland for adults aged 60 and older. The latter is also approved for pregnant women from the 32nd week of pregnancy to protect newborns. However, insurance coverage for these vaccines has not yet been clarified.

Vaccinating close contacts alone is not sufficient to adequately protect infants, so antibody immunization is strongly recommended to shield them during their first RSV season. The Travel Clinic UZH does not offer RSV immunizations for infants. However, for adults in risk groups who wish to be vaccinated against RSV with the Arexvy® vaccine, this service is available (currently at their own expense) at the Travel Clinic UZH.
