Exotic Viruses

Henipavirus
- Transmission
  - Fruit bat food remnants (fruit seeds)
  - Fruit bat urine
  - Fruit bat faeces
- Structure
  - Lipid Membrane
  - M Matrix protein shell
  - RNA
  - Nucleocapsid
  - Phosphoroprotein
  - Icosahedral
- Diagnostics
  - Immunohistochemistry
  - Serology
  - PCR
- Treatment
  - Ribavirin = reduces mortality
  - Symptomatic = limits neural damage via anti-inflammation
Flavivirus
- Transmission
  - Mosquitos and Ticks
- Structure
  - Icosahedral
  - Lipid membrane
  - M Matrix Protein shell
  - RNA
  - Nucleocapsid
  - Phosphoroprotein
- Diagnostics
  - Immunohistochemistry
  - Serology
  - PCR
- Treatment
  - Yellow fever = vaccine
  - Dengue = NO vaccine or treatment but vector control
  - West nile = NO vaccine or treatment but vector control
Emergence
- newly appeared in population
- not previously recognised in man (new to host)
- Stage 1 : only in animals
- Stage 2 : present in animals and humans but NO transmission between humans
- Stage 3 : present in animals and humans and undergo secondary transmission between humans
- Stage 4 : present in animals but primarily in humans and causes repetitive outbreaks that end by dieing out
- Stage 5 : present exclusively in humans
Re-emergence
- existed previously
- rapid increase in incidence
- rapid increase in geographical range (new to region)
- rapid increase in human host range
