  6. 6. INCUBATION PERIOD  It is highly variable in man,commonly3-8 weeks following exposure.  The closure the bite to the brain,the shorter the incubation.  Rabies virus travels one centimeters per day
  7. 7. DOG BITE
  8. 8. PATHOGENSIS  Live virus Epidermis , Mucus membrane Peripheral nerve centripetally CNS ( grey matter ) centrifugally Other tissues (salivary glands)
  9. 9. SIGN & SYMPTOMS  Bizarre behavior  Agitation  Seizures  Difficulty in drinking  Patients will be able to eat solids  Afraid of water – Hydrophobia  Even sight or sound of water disturb the patient  But suffer with intense thrist  Spasms of pharynx produces choking  Death in 1-6 days  Respiratory arrest/death/some may survive.
  10. 10. Continued..  Headache, fever, sorethroat  Nervousness, confusion  Pain and tingling at the site of bite  Hallucinations  Paralysis
  11. 11. PREVENTATION  PRE EXPOUSURE PROPHYLAXIS  POST EXPOUSRE PROPHYLAXIS
  12. 12. PRE EXPOSURE VACCINATION
  13. 13. PRE EXPOSURE PROPHYLAXIS  Provided to subjects at the risk before occupational or vocational exposure to rabies.  Subject include diagnosticians laboratory and vaccine workers, vatenarians, cavers.  Simplifies post exposure management.  Only vaccine used.
  14. 14. POST EXPOSURE PROPHYLAXIS  Provided to subjects after rabies exposure.  Consist of wound care, rabies immune globulin, and vaccine  Cleansing.  Chemical treatment.  Suturing.  Anti-rabies serum.  Antibiotics and anti-tetanus measure.  Observe the animal for 10 days.  Wash lesions well with soap and water.  Infiltrate rabies immune globulin (20 IU/kg) into and around the margin of bites.  Administer vaccine around 90 days.
  15. 15. RABIES IMMUNOGLOBULIN  Two Human Rabies Immunoglobulin are available;  Both supplied in vials at– 150 IU/ml
  16. 16. WOUND CLEANING & TREATMENT Wash the area of an animal bite thoroughly
  17. 17.  Initial treatment for an animal bite should include through cleansing however all animal bite should be seen by Physician.
  18. 18.  Apply pressure if bite is actively bleeding.
  19. 19. TREATMENT  POST EXPOSURE TREATMENT A. LOCAL WOUND TREATMENT Wash with soap/detergent and warter preferably for 10 minutes. Apply alcohol, povidone iodine/ any antiseptic. Anti-tetanus Avoid suturing wounds. Do not apply oinment, creams/ wound dressing
  20. 20. ANTIMICROBIAL Amoxicillin Cloxacillin Cefuroxime For those instances where there is no obvious signs of infection (Amoxicillin as prophylaxis)
  21. 21. VACCINE ADMINISTRATION 1. Intra muscular schedule 6 dosage schedule Reduced multisite intra mascular regime (2-1-1) 2. Intradermal schedule 2 site intradermal schedule(2-2-2- 0-1-1) 8 site intraderal schedule (8-0-4- 0-1-1)
  22. 22. Vaccination INTRADERMAL SCHEDULE Day of Immunization PVRV/PCECV Site DAY 0 0.1 ml L & R deltoids/ anterolateral thighs of infants DAY 3 0.1 ml L & R deltoids/ anterolateral thighs of infants DAY 7 0.1 ml L & R deltoids/ anterolateral thighs of infants DAY 28/30 0.1 ml L & R deltoids/ anterolateral thighs of infants
  23. 23. MANAGEMENT OF RABIES PATIENT  Once symptoms start, treatment should centre on comfort care, using sedation and avoidance of intubation and life support measures once diagnosis is certain.  MEDICATIONS Diazepam Midazolam Haloperidol + Dipenhydramine
  24. 24. 2. SUPPORTIVE CARE Confirmed rabies should receive adequate sedation and comfort care in an appropriate medical facility once rabies diagnosis has been confirnmed invasive procedure must be avoided Provide suitable emotional and physical support Discussion and provide important information to relative concerning tranmission of disease and indication for PET of contacts. Honest, gentle communication should be provided to relatives of patients.
  25. 25. 3. INFECTION CONTROL Patient should be admitted in a quiet, draft-free isolation room. HLCR workers and relatives in contact with patients should wear proper personal protective equipment. 4. DISPOSAL OF DEAD BODY
