The incubation period -- the time that elapses between contracting parvovirus B19 (the virus of fifth disease) and the start of the illness -- is 4 to 12 days. A person infected with parvovirus B19 is only contagious during the early part of the illness, before the rash appears.
How do you get the fifth disease?
Transmission. Parvovirus B19—which causes fifth disease—spreads through respiratory secretions, such as saliva, sputum, or nasal mucus, when an infected person coughs or sneezes. You are most contagious when it seems like you have “just a fever and/or cold” and before you get the rash or joint pain and swelling.
