Transmission of the human immunodeficiency v i rus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV), from a seropositive patient to a health c a re worker, can occur by accidental pricking with a needle or by wounds caused by cutting instruments. Although these exposures are not frequent , their medical and legal implications for sanitary personnel are important. Recommendations of post-exposure prophylaxis should be available to all health care workers with an assistencial function, because of the risk of transmission of contagious diseases with high morbi-mortality and the necessity of having a structural secuence of action. With this objective we performed this review and update of the "steps to follow in case of a biological accident", focussing on practical issues.
