Human migration and population health, including infectious disease, will be significantly impacted by anthropogenic climate change. It will magnify and change migration paths, as well as contribute to changing infectious disease ecology and transmission dynamics. However, in the context of a changing environment, there has been little discussion of the linkages between migration and health. This article proposes that climate-change-related migration, when combined with other migration variables, will result in altered infectious disease profiles. It takes into account the hazards of infectious illness linked with various climate-related migration patterns, such as forced displacement, slow-onset migration, particularly to urban-poor areas, planned resettlement, and labour migration associated with climate-change adaptation activities. Migration can help people become less vulnerable to climate change, but it's also important to study and respond to the health effects of migration, especially infectious illnesses, on migrant populations and host communities.
