A major tell-tale sign of fifth disease is developing a bright red rash on the cheeks a few days after seeing the cold/flu symptoms emerge. Still, at times, the rash may be the very first symptom that arises or is noticed. The good news is that once the rash does appear, patients are no longer contagious. In fact, once the rash surfaces, children can return to school as they aren’t at risk of spreading the virus at that point.
Rashes show up about 14 to 21 days after someone has been exposed to fifth disease, and can last anywhere from two weeks to 39 days. Unless your child seems very ill, is immune-compromised, or anemic, there is no need to reach out to a doctor; however, should their rash turn painful, purple, blister, or last over five weeks, it is encouraged to reach out for medical attention.
