  18. Genetic Factors: Some individuals may be more predisposed.
  19. Chronic Infections: Long-term illnesses can weaken immunity.
  20. Environmental Exposure: Close contact with contaminated water or soil.

Symptoms of MAC Infection:

  1. Persistent Cough: Lasting more than a month.
  2. Fatigue: Feeling excessively tired.
  3. Fever: Elevated body temperature.
  4. Night Sweats: Excessive sweating during sleep.

  6. Shortness of Breath: Difficulty breathing.
  7. Chronic Diarrhea: Lasting for more than a month.
  8. Abdominal Pain: Discomfort in the stomach area.
  9. Swollen Lymph Nodes: Especially noticeable in the neck.
  10. Skin Lesions: Sores or lumps on the skin.
  11. Joint Pain: Aching or discomfort in the joints.
  12. Vision Problems: Blurred or distorted vision.
  13. Headaches: Persistent and unexplained.
  14. Nausea and Vomiting: Frequent bouts of sickness.
  15. Chest Pain: Discomfort or pressure in the chest.
  16. Changes in Mental Function: Confusion or memory loss.

  7. Surgery: Removing infected tissue in specific cases.
  8. Immune Reconstitution: Improving overall immunity.
  9. Nutritional Support: Ensuring proper nutrition for recovery.
  10. Symptomatic Relief Medications: Addressing specific symptoms.
  11. Physical Therapy: Managing joint or muscle pain.
  12. Antifungal Medications: If fungal co-infection is present.
  13. Counseling and Support: Addressing mental health aspects.
  14. Oxygen Therapy: Supporting respiratory function.
  15. Fluid Replacement: Important for those with chronic diarrhea.
  16. Antiretroviral Therapy (ART): For HIV-positive individuals.
  17. Pulmonary Rehabilitation: Improving lung function.
  18. Monitoring and Follow-up: Regular check-ups for progress.
  19. Dietary Changes: Tailoring diet to individual needs.
  20. Infection Prevention Measures: Minimizing exposure to potential sources.

Drugs Used in MAC Infection Treatment:

  1. Clarithromycin (Biaxin): Fights MAC bacteria.
  2. Azithromycin (Zithromax): Effective antibiotic for MAC.
  3. Ethambutol (Myambutol): Included in combination therapies.
  4. Rifabutin (Mycobutin): Targets MAC bacteria.
  5. Amikacin: An injectable antibiotic for severe cases.
  6. Ciprofloxacin: Sometimes used in MAC treatment.
  7. Levofloxacin: Another antibiotic option.
