Triocomponental foci of infectious diseases are divided into:
Vector, interhostal, postinterhostal
Eradication of infectious disease means:
Reduction of an infectious disease’s prevalence in the global host population to zero
What are the rules of packaging infectious material for laboratory?
Rules of 3 layers
1) impermeable glass, plastic material
2) soaking material
3) outer container case
What are hosts of Rift valley fever?
Ruminants (wild and domestic), rodents, antelopes, wildebeests, human (dead-end host), african monkeys and carnivores
Transmission of Rift valley fever?
Direct and indirect, through fluids for humans (nasal discharge, blood, vaginal secretions after abortion, mosquito, meat, aerosols, milk)
Vector = mosquitos (they have vertical)
Hosts of blue tongue?
Domestic and wild ruminants (primarily sheep)
Division of the Newcastle disease virus strains according to their pathogenicity (virulence groups):
(Paramyxovirinae, Rubulavirus, genus Avulavirus)
Lentogenic - mild
Mesogenic - moderate
Velogenic - very virulent
Viscerotropic and neurotropic
Transmission of tularemia:
(F. tularensis)
Animals: direct contact or arthropods (ticks and mosquito), inhalation, food or water
Humans: direct contact or bitten by insects that have fed on animal, human to human not likely

Alimentary infection
What is the way of packaging a liquid sample containing potentially infectious material?
- Receptable
- Absorbent material
- Secondary packaging
- Outer packaging of adequate strength
- All must be leak proof
What is the practical difference in working in BSL-3 and BSL-4?
In BSL-4, you need a positive pressure suit
