Biological hazards

                                                            Abstract

Biological hazards remain a source of challenge to the health services and to health service occupational health practitioners. The scale of the problem is truly staggering.  Recent developments include new guidance from the WHO department of hepatitis B infected healthcare workers and evidence of the value of antiviral treatment in reducing transmission of HIV. The possibility of greater occupational transmissible of hepatitis C and increasing antibiotic resistance remain of concern.
