Overview
Parvovirus B19 is a virus that can cause symptoms like a rash and joint pain. It’s the virus that causes fifth disease in kids. But it can also make you sick as an adult.
A parvovirus infection in kids is more likely to cause a rash. As an adult, you might not have a rash, but instead have joint pain similar to arthritis. This can last for weeks or months.
People who are pregnant, have a weakened immune system or who have certain blood disorders are at a higher risk of serious complications from parvovirus infections.
B19 is the most well-known parvovirus, but other parvoviruses can infect people. These include human tetraparvoviruses, human bocaparvoviruses and human protoparvoviruses. They all cause similar symptoms.
