Scientists at the University Hospital of Lausanne (CHUV) warned of a parvovirus outbreak on Friday. Outbreaks are currently being monitored internationally. Parvovirus B19 poses a potentially serious risk to the fetus in pregnant women.

In adults and children, the virus causes symptoms such as moderate fever, headache, runny nose, or rash on the arms, legs, and trunk. Children’s faces develop a characteristic flush on the cheeks. The disease is harmless and goes away within a few days.

The virus is transmitted through the respiratory tract, just like Covid-19 or flu. “However, in pregnant women, this virus may pose a significant risk to the health of the fetus,” says David Baud, head of the CHUV maternity ward in Lausanne, in response to a question from the Keystone-SDA news agency.

Heart problems after birth

If a woman becomes infected with parvovirus B19 during pregnancy, the virus can cross the placenta and infect the fetus. The most feared complication is “fetal anemia”, which can lead to serious complications and even fetal loss.

Additionally, parvovirus B19 can affect the cardiovascular system of the fetus, increasing the risk of heart problems after birth.

Outbreaks also occur in France and Israel

Therefore, it is very important for pregnant women to be educated about the virus. Follow-up care may reduce pregnancy risks. If a pregnant woman comes into contact with a person carrying parvovirus B19, she should inform her gynecologist immediately. A simple blood test can be used to determine whether the patient is currently protected.

According to Baud, the current epidemic can be explained by the fact that the virus hardly spread during the Covid-19 pandemic and therefore many young children were not vaccinated. Therefore it is now a rebound effect. Outbreaks were also observed in other countries, especially France and Israel. (SDA)
