Four Types of VHF Arenaviruses:
Lassa & Latin American Fever Carried by rats and mice Transmitted by feces and urine
Bunyaviruses: Crimean-Congo & Rift Valley Transmitted though a arthropod vector
Filoviruses: Ebola & Marburg Host of virus is unknown, possible bats
Hemorrhagic Flaviviruses: Yellow & Dengue Arthropod vector

Post Incident Actions No current post exposure prophylaxis
A fever of over 101F will trigger isolation and treatment
Will be isolated at home or hospital
Supportive treatment as needed
Information will be provided on how to protect family
