🌍 Major World Health Issues

1. Infectious Diseases

   • COVID-19, Influenza, Tuberculosis (TB), HIV/AIDS, Malaria, and Hepatitis remain major concerns.

   • Emerging diseases (like Ebola or new coronaviruses) highlight the need for strong global surveillance systems.

2. Non-Communicable Diseases (NCDs)

   • Include heart disease, stroke, cancer, diabetes, and chronic respiratory diseases.

   • Responsible for over 70% of global deaths.

   • Often linked to poor diet, physical inactivity, smoking, and alcohol use.

3. Mental Health

   • Depression, anxiety, and suicide are growing concerns worldwide.

   • Stigma and lack of access to mental health care make it worse, especially in low-income regions.

4. Malnutrition

   • Includes undernutrition (especially in children) and obesity (a rising issue globally).

   • Leads to stunted growth, weakened immunity, and chronic diseases.

5. Environmental Health Issues

   • Air and water pollution, climate change, and deforestation contribute to respiratory illnesses, heat-related diseases, and food insecurity.

6. Access to Healthcare

   • Many people in low- and middle-income countries lack access to affordable, quality healthcare.

   • Issues include poor infrastructure, shortage of healthcare workers, and lack of essential medicines.

7. Maternal and Child Health

   • High rates of maternal mortality, infant mortality, and child malnutrition persist in some regions.

8. Antimicrobial Resistance (AMR)

   • Overuse and misuse of antibiotics are making infections harder to treat, threatening to undo decades of medical progress.

9. Vaccination and Preventable Diseases

   • Vaccine hesitancy and inequality in vaccine access lead to outbreaks of diseases like measles and polio.

10. Global Pandemics and Health Emergencies

• Preparedness for future pandemics, like COVID-19, is crucial to protect economies and save lives.
