Virology

Adenovirus (Family: Adenoviridae)

• Adenoviruses are Non-Enveloped DNA Viruses
• In Humans, There are Approximately 88 Adenoviruses in 7 Different Species (Species A-G)
  • Respiratory Disease is Predominantly Associated with Adenovirus Species HAdV-B and HAdV-C
  • Conjunctivitis is Predominantly Associated with Adenovirus Species HAdV-B and D
  • Gastroenteritis is Predominantly Associated with Adenovirus Species HAdV-F Types 40, 41, HAdV-G Type 52
  • Obesity/Adipogenesis is Predominantly Associated with Adenovirus Species HAdV-A type 31, HAdV-C Type 5, HAdV-D Types 9/36/37
