About Global Health
The spread of a disease doesn't stop at a country's borders. With more people living in crowded cities and traveling to other countries, it's easier for germs to spread. Infectious diseases that start in one part of the world can quickly reach another part of the world. Some of the major diseases currently affecting countries around the globe include HIV, malaria, COVID-19, and tuberculosis.
Besides the spread of diseases, there are other global health challenges. Resistance to medicines such as antibiotics is on the rise. That makes it harder to treat certain diseases. Natural and man-made disasters create refugee populations with immediate and long-term health problems. Climate change and not enough access to food and safe water are also global problems which can affect people's health. Many countries and health organizations are working together and sharing information on these and other health issues.
It sits within Health System.
When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.
Research on Global Health
656 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.
What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
