[Comparative study on the identification of occupational risks for nursing workers at 2 basic health units of the municipality of Sao Paulo].

Occupational risks of nursing work in Basic Health Units have not been study frequently, so it stimulate us to develop this paper, whose objective are: to compare the perception of nursing workers of two Basic Health Units about these risks and to establish a parallel between the health problems with their exposition to occupational risks. Data were collected by an interview and were analyzed according to their frequencies. Biological risks were observed more frequently. The conclusions show that nursing workers have difficult to understand the genesis of occupational risks.
