Public Health Research is an essential peer-reviewed journal that energetically engages with key public health issues that have come to the fore in the global environment — mounting inequalities between rich and poor; the globalization of trade; new patterns of travel and migration; epidemics of newly-emerging and re-emerging infectious diseases; the HIV/AIDS pandemic; the increase in chronic illnesses; escalating pressure on public health infrastructures around the world; and the growing range and scale of conflict situations, terrorist threats, environmental pressures, natural and human-made disasters.
