QUESTION 1

Biological factors that need to be considered when designing a strategy to control an infectious disease (Handel et al , 2007

Mode of transmission of the infectious agent

Species and nature of the infectious agent , e .g , bacteria , virus viroid , etc

Doubling time of the infectious agent

Number of days of incubation until symptoms are observed in an infected person

Mode of reproduction of the infectious agent

Resistance and

sensitivity of the causative agent

Number of strains or species associated with the infection

Severity of infection , e .g , outbreak , endemic , pandemic , etc

Natural habitat of the infectious agent

Method of containment of the infectious agent

Comparison of biological factors for AIDS and influenza

Biological factor AIDS Influenza

Mode of transmission Body fluids , e .g , blood , semen , saliva , urine tears Direct contact with infected person , air-borne transfer

Species and nature of infectious agent Human immunodeficiency virus-1 (HIV-1 ) Influenza virus

Doubling time of infectious agent 10 hours 17 hours

Incubation days until symptoms are observed 2 to 4 weeks 1 to 5 days

Mode of reproduction of infectious agent Clonal reproduction Clonal reproduction

Resistance and sensitivity of infectious agent Resistant to protease inhibitors Resistant to anti-viral drugs

Number of strains associated with the infection Four strains (M , O , N and

) 3 strains (A , B and C

Severity of infection Epidemic Pandemic

Natural habitat of the infectious agent Chimpanzees Wild and domestic birds
