Health systems are generally structured around nation-states. Migration, especially across national borders, therefore leads to challenges.
Keeping track of migration and urbanisation is challenging, but it's vital for population health that migration and urbanisation is well understood and planned for.
Health responses need to take on board the fact that the number of women and girls migrating across borders as well as within countries is growing.
It's difficult to keep track of the medical records of patients on the move and some may be lost to follow-up, presenting further public health challenges and population-wide risks.
Excluding international migrants from the public health care system can result in a population wide risk.
