[VI Symposium: Some global health problems with local impact: Great challenges for Public Health].

The objective of the symposium was to emphasize the great public health challenges that we are facing today; such is the case of dementia, which is one of the main causes of disability and dependence among older adults. Another important issue is antibiotic resistance; even though it has played a key role in the health of humanity, its indiscriminate use has resulted in increased bacterial resistance. Therefore, health regulations in the rational use of prescribed drugs in our country are part of the actions taken in order to not only control the use of such drugs, but also regulate different areas related to health in order to avoid health risks. Finally, a current challenge is emerging and reemerging diseases that have caused various epidemics such as influenza, Ebola virus disease, binomial tuberculosis and HIV, and Chikungunya that is currently affecting the Region of the Americas.
