- Depression affects over 280 million people worldwide.
- Suicide is a leading cause of death among young people.
⚠️ Causes:
- Genetic predisposition, trauma, stress, social isolation.
- Lack of support systems.
✅ Treatment and Support:
- Therapy and counseling.
- Psychiatric medications.
- Community awareness and stigma reduction.
- Integrating mental health into primary care.
8.
Malaria and Vector-Borne Diseases

- Malaria alone kills nearly 600,000 people annually, mostly in sub-Saharan Africa.
- Others include dengue, Zika, chikungunya.
⚠️ Causes:
- Mosquitoes (Anopheles, Aedes species).
- Warm, humid climates; poor sanitation.
✅ Prevention:
- Insecticide-treated bed nets.
- Antimalarial drugs and vaccines.
- Vector control programs.
- Public awareness.
9.
Antimicrobial Resistance (AMR)
📊 Global Impact:
- Threatens the effectiveness of antibiotics.
- Could cause 10 million deaths annually by 2050 if unchecked.
⚠️ Causes:
- Overuse and misuse of antibiotics.
- Poor infection control in healthcare settings.
- Lack of new antibiotics.
