Scott Y1 - 2019 N1 - T2 - McGraw-Hill's NAPLEX® Review Guide, 3e AB - Influenza is a viral infection that attacks your respiratory system (nose, throat, and lungs) causing significant morbidity and mortality, particularly among children and elderly. Influenza occurs at any time during the year, but the highest rates occur between December and March. Influenza A and B are the two types of influenza viruses and influenza A is further categorized into subtypes based upon two surface antigens (hemagglutinin and neuraminidase). Immunity to influenza occurs from antibody development directed at the surface antigens.
