Question
To avoid the spread of communicable diseases we must break the chain of infection. This can be done at each link in the chain. Which of the following match the link in the chain of infection with an appropriate action that breaks the chain of infection at that link?Group of answer choicesPathogen: exercisePortal of entry: avoid touching door knobsPortal of exit: covering your coughTransmission: antibiotics
Solution
The correct matches for each link in the chain of infection with an appropriate action that breaks the chain of infection at that link are:
-
Pathogen: This is not correctly matched with 'exercise'. A more appropriate action would be 'use of antibiotics or vaccines' as these directly target and eliminate pathogens.
-
Portal of entry: 'Avoid touching door knobs' is a correct match. Door knobs are common surfaces that can be contaminated with pathogens. By avoiding touching them, or by cleaning hands after touching them, we can prevent pathogens from entering our body.
-
Portal of exit: 'Covering your cough' is a correct match. When we cough without covering, we can spread pathogens into the environment. By covering our cough, we can prevent the pathogens from exiting our body and infecting others.
-
Transmission: This is not correctly matched with 'antibiotics'. A more appropriate action would be 'hand washing or use of sanitizers' as these practices can prevent the transmission of pathogens from one person to another.
