The issue of homelessness is a far too frequent presence in our lives. Cities across our nation offer a disturbing display of a challenging and multivariate public health issue. From resource funding, to training, knowledge, and experience for public health leaders, to every one of us; we must be aware and sensitive to help those in need. The challenges are numerous and the time to mitigate homelessness may be lengthy, but we all must be aware of our common call to help those in need. A particular mention of homeless veterans is offered.
