Do you get slapped cheek syndrome twice?

Yes, it is possible: Slapped cheek disease is caused by the erythrovirus( previously called parvovirus b19). It is spread primarily by respiratory secretions, such as saliva and mucus, but can also be spread by contact with infected blood. Therefore, if you comes into contact with the virus more than once, and you had not developed immunity, you will get disease again. Most common in children 5-15 years old.
