title: Hepatitis type A in an oral surgeon: a prospective study of contacts.
abstract: No acute cases of clinical or anicteric hepatitis were in observed in 75% of 161 patients who had been exposed to hepatitis A by an oral surgeon during the contagious period. Three cases of liver dysfunction of indeterminate cause did occur, although at least two could be attributed to multiple abuses of drugs 3-5 and not to exposure to hepatitis. The fact that hepatitis A did not spread in this instance suggests that oral surgeons who are ill with acute hepatitis A do not necessarily transmit the disease to their patients. Epidemiologic investigations of similar situations will undoubtedly augment this preliminary data.
