Fifth disease is a viral infection caused by parvovirus B19, it is usually a mild illness and spread through respiratory secretions just like a cold.
Fifth Disease is usually diagnosed by the appearance of a red rash on the face known as a “slapped cheek” rash. A rash may also appear on the chest, back, buttocks, arms, and legs and may be itchy with a lacy appearance. The rash typically lasts about a week but may come and go for several weeks especially when exposed to sunlight or heat. Once the rash appears, the person is generally considered no longer contagious and can usually return to school or work. The first symptoms of Fifth Disease are usually fever, runny nose, and headache, but 20% of children and adults who are infected have no symptoms at all. Some people with Fifth Disease may also experience painful or swollen joints. This is most common in adults, particularly women.
How to avoid the spread of this and other infections:
frequent hand washing
covering your mouth and nose when you cough or sneeze
avoid touching your eyes, nose, mouth
avoid close contact with ill people
stay home when you are sick
Children with any rash are advised to be seen by their physician before attending school.
Populations at risk:
Pregnant women should consult with their obstetrician if they have been infected or exposed to an infected individual because in rare instances it can cause complications such as anemia in the fetus. About half of pregnant women have been previously exposed to the virus therefore usually immune.
People with weakened immune systems should contact their physicians because they are at risk for serious complications due to Fifth Disease infection.
