The world is becoming more globalized socially and therefore it is necessary to think about health in a global context.
Global Health is an area of study, research, and practice that places a priority on improving the health for all people around the world, using a full range of public health and health promotion strategies. There are different definitions of global health but this is the one we prefer to use, partly from Kaplan JP etal. Lancet 2009, 373:1.
Global health crucial and affects everyone:
1.Rarely a week goes by without a headline about the emergence or re-emergence of an infectious disease or other health threat somewhere in the world.
2.Example of Ebola and Zika virus
3.You can travel to certain countries without being vaccinated in the hope that you don’t get sick and bring the sickness back to your home countries
4.You can’t travel to certain countries if you have certain infectious diseases
5.A sickly nation can be a burden to itself and other nations who have to spend resources to reduce the impact of the disease instead of funding infrastructure, money is going to fighting preventable diseases.
