Increased Parvovirus B19 activity in Europe, ECDC emphasises enhanced awareness for vulnerable populations

B19V is the cause of a common childhood disease, typically presenting with mild symptoms such as fever, rash, and joint pain. Pregnant women, especially those in the first part of pregnancy, are at risk of complications if infected with B19V. Immunosuppressed individuals and those with chronic haematological disorders (e.g. sickle cell or thalassemia) may also experience severe complications like anaemia, chronic infection, or other serious adverse events.

ECDC urges healthcare providers to maintain vigilance for B19V infection when evaluating patients and to counsel those at higher risk for severe complications. In the context of community outbreaks, pregnant women, particularly if working in education or childcare, should contact their health provider to check their antibody status. They should also take appropriate precautions, such as avoiding contact with sick persons and staying or working from home, if possible. Individuals with underlying health conditions experiencing fatigue, paleness, or shortness of breath are advised to seek prompt medical attention.

Public health authorities are encouraged to enhance awareness among both healthcare professionals and the general public regarding the potential risks and symptoms associated with B19V infection, particularly for vulnerable populations. Reviewing historical B19V epidemiological data to better understand transmission dynamics and reporting at the EU/EEA level will help inform targeted risk communication strategies.
