Multiple choice

Which of the following is NOT a mode of transmission for infectious diseases?

  1. Direct contact

  2. Indirect contact

  3. Airborne transmission

  4. Vector-borne transmission

  5. Fomite transmission
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Vector-borne transmission is not a mode of transmission for infectious diseases. It is the transmission of a disease by an arthropod, such as a mosquito or tick.

Multiple choice

Which of the following is NOT a common source of data for non-communicable disease surveillance?

  1. Hospital records

  2. Vital statistics

  3. Population surveys

  4. Environmental monitoring
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Environmental monitoring is not typically used for non-communicable disease surveillance, as it is more commonly employed for monitoring infectious diseases and environmental hazards.

Multiple choice

How do viruses replicate?

  1. By hijacking the host cell's machinery

  2. By creating their own copies of genetic material

  3. Both of the above

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Viruses replicate by hijacking the host cell's machinery to create copies of their own genetic material and proteins. They then assemble these components into new viruses that can infect other cells.
