Gastrointestinal Viruses

This topic focuses on viruses causing gastroenteritis, including Rotaviruses, Noroviruses, Astroviruses, and certain Adenoviruses. It covers their structure, pathogenesis (damage to intestinal epithelium), clinical features, transmission (fecal-oral route), and laboratory diagnosis (antigen detection, EM). For Zambian college and university students, especially in paediatrics and public health, this is highly relevant due to the significant burden of viral diarrhoea in children. Understanding these pathogens is crucial for disease prevention, outbreak management, and examination preparation.
