Micro 53: Bunyaviridae and Arenaviridae
This episode explores two families of enveloped negative-sense RNA viruses often associated with zoonotic transmission and severe systemic disease. Drawing from Murray’s Chapter 53, it examines ecological reservoirs and genomic structure as determinants of epidemiology.
The Bunyaviridae family (now taxonomically expanded but conceptually preserved in Murray) includes viruses transmitted by mosquitoes, ticks, or rodents. Many possess segmented genomes, allowing reassortment. Clinical manifestations range from febrile illness to haemorrhagic fever and encephalitis.
The Arenaviridae family…
