Report on Hemorrhagic fevers: - etiology, clinic, prophylaxis
HF syndrome associated with vascular instability & ↓ vascular integrity.
Direct or indirect attack on micro
vascular permeability (esp.
when PLT function is ↓ ) to actual disruption and local hemorrhage.
Pathogenesis is
poorly understood and varies among the viruses that are involved.
The acute phase in the most of the HF’s are
associated with virus replication and viraemia .
except hanta virus and dengue fever in which the immune response
plays a main pathogenic role.
Yello fever:Etiology:- Flavi virus ( in Africa and in south America) .
transmitted from monkey to human by mosquito.
Clinics:- IP 3-6 days.
In mild cases the disease is indistinguishable from other viral infections as influenza or
dengue.
Classically jaundice, protienuria, hemorrhage can occur
Initial phase:- acute high fever 39 – 40 deg C (normalize in 4-5 days), Head ache, Retro bulbar pain, myalgia,
arthralgia, flushed face, suffused conjuncti
