Questions and Answers
  • 1. 
    A 10-month-old boy is brought to an outpatient clinic by his mother. The child has been sneezing, has a cough, and his nose is constantly running. There is no evidence of fever, pharyngeal inflammation or lower respiratory tract involvement. It is late February and the regional health authorities have requested that physicians provide them with nasopharyngeal samples for an epidemiological study. A nasopharyngeal aspirate is collected and sent to the regional health authorities. The virology lab establishes that this sample contained an enveloped, segmented, negative-polarity, single-stranded RNA virus, approximately 100 nm in diameter.
