The Department of Medicine, Health, and Society affirms that anti-Black racism is a primary driver of disease and death, and that police violence, which disproportionately targets people of color, is an urgent public health concern. MHS supports Black Lives Matter, and calls for justice in the police killing of George Floyd along with the many Black and Indigenous people killed before him because of White supremacy. As faculty, staff, and students, members of the MHS community commit to supporting and enacting antiracism in research, teaching, and administrative practices, in recognition of antiracism as a key element of collective health and thriving. We call upon our colleagues to share their support and solidarity for Black people and Black lives.
