Emerging IDs Flashcards
Deliberate disease
Intentional introduces
Re emerging diseases
Once posed health issues then decr dramatically and are resurging again
Key reservoirs for viral zoonosis
Bats
Rodents
EID hotspot
Regions where diseases are more likely to originate usually have high pop density and are ill equipped to cope
Categories of EIDs or ReIDs
Tropical
Non tropical
Drug resistant pathogens
Re emerging
Drivers for EID
Land use changes Enviro changes Human demographics and behaviour changers Technology and industry Pathogen changes
Cause of nipah virus emergence
Deforestation
Urbanisation
Incr pig pop
Ebola emergence
Bush meat consumption Wildlife encroachment Poor health systems Tourism Governance breakdown
Influenza emergence
Species mixing
Pathogen changes
High pop densities
Travel
Pandemic zoonoses stages
1- between reservoirs spread geographically - more likely spill over
2- initial spill over to humans
3- person to person wide spread pathogen travel. Vector translocation
Life sciences response
Develop diagnosis and therapeutic techs
Drive lab research
Food & agri industry response
Culling
Product recall
Human &I vet health care sector response
Monitor pops
Provide care
Give preventative interventions
Provide trained profs and animal handlers
Global response
WHO report all EID that could globally spread
Notify other countries through global alert and response network
Assess transmission risk
Establish control measures
What is an EID
Newly recognised in a population or occurred before but now incr incidence/ expansion, vector host range
