parvovirus B19: Is ‘Slapped Cheek’ syndrome on the rise? Know symptoms, prevention and more

Parvovirus B19, which causes “slapped cheek” syndrome, has been more common recently, especially in children in the US. Following a noticeable spike in cases across Europe in the first few months of the year, the virus was said to be spreading. The number of infections among children aged five to nine has increased dramatically from 15% in 2022 to 40% by June 2024, prompting the CDC to issue a health alert last week. Adults who work closely with children in healthcare and educational environments are also more susceptible to illness, as per the reports of Metro.co.uk.

Understanding the virus

Parvovirus B19 is a seasonal respiratory virus that is also known as “slapped cheek” disease or fifth disease. It is transmitted by respiratory droplets from infected people, whether or not they exhibit symptoms. The term “slapped cheek” refers to the characteristic red rash that appears on children’s cheeks, giving the impression that they have been slapped. In addition to being airborne, the virus can also spread by blood transfusions or plasma products, as well as from a pregnant woman to her fetus.

Symptoms of Parvovirus B19

The initial signs of the virus are fever, generalized discomfort, and joint pain. These symptoms often arise a week or so after infection and remain for approximately five days. People are extremely infectious during this time. After that, children frequently get erythema infectiosum, or a face rash, seven to ten days later. One to four days after this rash, a body rash with a web-like appearance may develop. It is noteworthy that the facial rash typically appears following the reduction of the infectious stage. Some virus-infected individuals might not show any symptoms at all.

Treatment and prevention

As of right now, there isn’t a specific parvovirus B19 vaccine or treatment available. Pregnant women who exhibit symptoms or have been in contact with someone infected with the virus are advised by the CDC to consult a doctor. Patients with compromised immune systems or long-term blood issues ought to speak with medical professionals as well. Wearing a mask can help lower the chance of infection. People infected with parvovirus B19 usually lose their ability to transmit the virus after they develop the distinctive face rash.
