Current Issues
Antibiotic Resistance
- Antibiotic resistance is a serious issue where bacteria evolve to become resistant to antibiotics used to treat them.
- This is a direct consequence of the overuse or misuse of antibiotics, for instance, not completing a full course, thereby allowing some bacteria to survive and adapt.
- The rise of ‘superbugs’ – bacteria that are resistant to multiple types of antibiotics – is particularly concerning.
- Scientists are constantly striving to develop new antibiotics that can successfully target these resistant bacteria.
Vaccination Hesitancy
- Vaccination hesitancy refers to the reluctance or refusal to vaccinate, despite the availability of vaccines.
- Main reasons include fears about vaccine safety, lack of trust in healthcare providers or vaccine manufacturers, or belief in vaccine myths.
- This can lead to declines in vaccination coverage and resurgence of preventable diseases.
- Vaccine hesitancy has been identified by the World Health Organization as one of the top ten threats to global health.
Emergence of New Diseases
- New diseases, often referred to as emerging infectious diseases, can pose major challenges in prevention and treatment.
- These can be entirely new infections (like COVID-19), or known diseases spreading to new regions (like Zika virus).
- Rapid global travels and urbanization can accelerate the spread of these diseases making them difficult to control.
Disease Eradication
- Disease eradication is the complete and permanent worldwide reduction to zero new cases of the disease.
- Notable success stories in disease eradication include smallpox, which was declared eradicated in 1980 thanks to a global immunization program.
- Current targets for eradication include polio and Guinea worm disease.
- However, issues like vaccination hesitancy, conflict zones, hard-to-reach populations, and other social, political, and economic barriers make disease eradication a complex target.
Health Inequalities
- Health inequalities denote the differences in health status or in the distribution of health resources between different population groups.
- This can lead to certain groups having better access to advanced treatments while others do not.
- Such disparities can be based on factors such as socioeconomic status, geography, gender, age, or ethnicity.
