Health care workers are unlikely to get blood borne illnesses from their patients because there are safety practices in place to minimise the risk of exposure.
Explanation:
Health care workers wear appropriate PPE (personal protective equipment) when dealing with patients who may be carrying a blood borne illness. They should be vaccinated against the blood borne pathogens that have vaccines developed.
I think that health related professions are important in the society because they give there opinions to keep us healthy, and they also have backup plan when we are sick to try to make us better.
