Global Health: Past and Present
The global health history timeline has numerous milestones that gave rise to current practices.
- History: Ancient societies made effort towards waste management and infectious diseases control.

In this development they demonstrate clearly remarkable achievements as well as changing trends in global health.
Key Concepts in Global Health:
Social Determinants of Health:
- Economic status.
- Education levels.
- Cultural conditions.
- Environmental influences.
Epidemiology and Disease Burden:
- Rate of incidence and prevalence.
- Local case fatality rate.
- Disability adjusted life years (DALYs).
- Disease patterns.
Health System:
- System of governance and policies.
- Health resources.
- Models of health service delivery.
- Devices of health finances and insurance.
Global health politics:
- Functions of world health organization.
- Health policies.
- International agencies.

Health Equity:
- Provision of healthy care services.
- Imbalance among populations.
- Interventions.
- Moral issues.
Major Global Health Challenges:
Crises due to natural or synthetic disaster and the changing nature of disease are some of the great obstacles. Chronic disease ignore the health service and generate troubles among the rest of the world. More than 70% of deaths worldwide are caused by non-communicable diseases (NCDs) such as heart disease and diabetes.
Infectious Diseases:

- Telemedicine: Forms of technology which makes lonely patients talk to the physician through the phone.
- Mobile Health (mHealth): Use mobile telephone in health monitoring as well as in providing health information.
- Electronic Health Records (EHRs): Help to gather visceral treatment information with technology.
- Wearable Devices: Offer patients electronic wrist bands that record certain activities during the day and continuously monitor health improvements.
With those technologies being exploited to the fullest, health practitioners are capable of administering high quality and more equitable care around the world, thus promoting better health.
