An anonymous reader writes: A new survey published in JAMA Pediatrics found that 95% of doctors believe patients are put at risk when doctors work while sick. Despite that, 83% of respondents said they had "come to work with symptoms like diarrhea, fever and respiratory complaints during the previous year." The researchers doing the survey dug into the reasons for this: first of all, given the heavy workload of most doctors, it's very difficult to find others who can take up the slack when one is recovering from an illness. Beyond that, the profession is pervaded by a culture of working through the discomfort and pain of minor maladies. According to a commentary on the research, hospital policies don't help matters — they often incentivize long hours and don't encourage ill workers to leave the premises.
