Flu-Like Symptoms
Since the fifth disease is caused by viruses, it tends to have many similar symptoms to the flu. They occur when the immune system starts working to eliminate foreign invaders and protect the body. Typical signs include a sore throat, nausea, fatigue, low-grade fever, headache, as well as a runny nose. They would show up 5 to 10 days after exposure to the triggering virus. It is hard to diagnose the fifth disease only based on flu-like symptoms. You need to notice other signs like rashes and joint pain, as well as additional tests to get a precise diagnosis.[3]
