  • 9. MOOD OF TRANSMISSION : All means of transmission being involved Except :  Soil contact  Vertical.
  • 10. Host susceptibility
  • 11. HOST SUSCEPTIBILITY : Age. Gender. Occupation.• Neonates. • No • Intensive care• elderly predominance. units. patients • Emergency department. • Laboratory medicine..
  • 12. HOST SUSCEPTIBILITY : General medical condition: Environmental factors:• Chronic ill patients. • Variety of medical• Immunocompromised. procedures.• Long term medical devices . • Invasive techniques creating potential routes of• Long term antibiotics infection.• Bedridden state. • Drug-resistant bacteria.• Low activities . • Crowded hospital populations. • Poor infection control practices .

  • 14. DIAGNOSIS AND TREATMENT : Diagnosis is clinical scenario oriented . Cultures for blood, urine, stool and even sputum samples. Viral serology should always be considered. Treatment is case oriented . But the initial must be empirical and wide spectrum coverage.
  • 15. PREVENTION : General Measures:  Health education:  Not only to the patient or visitors but medical staff also.  Educate the medical staff about (HAI) mood of transmission . ect.

  • 25. ENVIRONMENTAL HAZARDS CONTROL:  Safe water supply .  Prober disinfection.  Sanitary disposal of waste .  Food sanitation and food handlers control.
  • 26. ENVIRONMENTAL HAZARDS CONTROL:  Dust control .  Control of respiratory droplets .  Regular instrumental sterilization.  Usage of disposal instruments.  Blood and its products screening.  Collaborating .
