OccupationalHealthHazardsamongDoctorsand Nurses
Risk of catching resistant infections and sometimes there is risk that they carrythese deadly bacteria to their homes. So their family members and children areat risk.Risk of working in disaster areas, floods, earthquakes.
Change in natural bio flora of doctors and nurses. It is replaced by hospital bioflora. If they get infection, it is difficult to treat.
Risksbecauseoflegalproblemsand violent patients: Legaltroubleaddstofurther stress.Verbalabuseandthreateningisverycommon.Fear of physical assaultcanreallyharmdoctorsandfamilymembers.Excessiveandunilateralregulationputsdoctorsatthereceivingendofthediscontent(doctorsalways blamed).
