Fifth Disease is caused by which virus?

Explanation:
Fifth disease is caused by Parvovirus B19. This small, nonenveloped DNA virus infects red blood cell precursors in the bone marrow and commonly produces the telltale slapped-cheek facial rash in children, followed by a lacy, spreading rash on the body. Other viruses listed cause different illnesses—Rhinovirus gives the common cold, Varicella-zoster causes chickenpox and shingles, and Adenovirus can lead to conjunctivitis or respiratory infections—so Parvovirus B19 is the match for erythema infectiosum.
