Each year, infection with Human Papillomavirus (HPV) leads to millions of abnormal Pap smears and thousands of cases of cervical cancer in the US. Throughout the developing world, where Pap smears are less common, HPV is a leading cause of cancer death among women. So when the international pharmaceutical giant Merck developed a vaccine that could prevent infection with several key strains of HPV, the public health community was anxious to celebrate a major advance. But then marketing and lobbying got (...) in the way. Merck chose to pursue an aggressive lobbying campaign, trying to make its new vaccine mandatory for young girls. The campaign stoked public mistrust about how vaccines come to be mandated, and now it's not just Merck's public image that has taken a hit. The public health community has also been affected. What is the lesson to be learned from this story? Public health communication relies on public trust. (shrink)

Responses to public health emergencies can entail difficult decisions about restricting individual liberties to prevent the spread of disease. The quintessential example is quarantine. While isolating sick patients tends not to provoke much concern, quarantine of healthy people who only might be infected often is controversial. In fact, as the experience with severe acute respiratory syndrome (SARS) shows, the vast majority of those placed under quarantine typically don't become ill. Efforts to enforce involuntary quarantine through military or police powers also (...) can backfire, stoking both panic and disease spread. Yet quarantine is part of a limited arsenal of options when effective treatment or prophylaxis is not available, and some evidence suggests it can be effective, especially when it is voluntary, home-based and accompanied by extensive outreach, communication and education efforts. Even assuming that quarantine is medically effective, however, it still must be ethically justified because it creates harms for many of those affected. Moreover, ethical principles of reciprocity, transparency, non-discrimination and accountability should guide any implementation of quarantine. (shrink)

Confidentiality is a core value in medicine and public health yet, like other core values, it is not absolute. Medical ethics has typically allowed for breaches of confidentiality when there is a credible threat of significant harm to an identifiable third party. Medical ethics has been less explicit in spelling out criteria for allowing breaches of confidentiality to protect populations, instead tending to defer these decisions to the law. But recently, issues in military detention settings have raised the profile of (...) decisions to breach medical confidentiality in efforts to protect the broader population. National and international ethics documents say little about the confidentiality of detainee medical records. But initial decisions to use detainee medical records to help craft coercive interrogations led to widespread condemnation, and might have contributed to detainee health problems, such as a large number of suicide attempts several of which have been successful. More recent military guidance seems to reflect lessons learned from these problems and does more to protect detainee records. For the public health system, this experience is a reminder of the importance of confidentiality in creating trustworthy, and effective, means to protect the public's health. (shrink)
