摘要
Most cases of parvovirus B19 infection are asymptomatic and occur in childhood; half of all 15-year-old adolescents have specific anti-parvovirus B19 antibodies. Here, we report a rare case of parvovirus B19 primary infection, rare due to (1) its occurrence in a geriatric patient (an 82-year-old woman), (2) its lupus-like presentation, and (3) its potential role in precipitating congestive heart failure.
