5 FACTORS INFLUENCED TO INCREASED OF INFECTIOUS DISEASES IN INDONESIA (1) Economic Development, Changed of Demografic and Life Style in Community; (2) Development of Transportation  Increased of Traveller inter-region, island, and city in Indonesia. (3) Environmental changed  Disaster in many areas in Indonesia, and many projects irigations ? (4) Limitation of manpower and health sevices in community; (5)Non hygiene of foodhandling  transmission of bacteriae (Salmonella typhi); (6)Mutation and Evolution of organism  new strain emerge and antibiotics resistancy.

6 EMERGING INFECTIOUS DISEASES IN INDONESIA (A)Vector borne Disease : (1) DF/DHF (2) Chikungunya (3) Japanese Encephalitis (4) Malaria (5) Filariasis (6) Leptospirosis (7) Toxoplasmosis; (B)Sexual Transmitted Disease (STD); (C)Airborne Disease : (1) Tuberculosis (2) Influenza. (D)Food and Water borne Disease : (1) Typhoid Fever (2) Diarrhoae.

7 FOOD AND WATER BORNE DISEASES. (1) TYPHOID DAN SALMONELLOSIS : The sanitary factor and hygienic food and water take was responsibility on the increase of the morbidity of typhoid fever. (2)DIARRHOEA : Many causes of diarrhoea, and the strain of Cholera Vibrio O 139 from Bangladesh was a potentially factor to increase the case of diarrhoea in Indonesia.

9 TEN MAIN DISEASES IN INDONESIA URBAN/RURAL AREA

10 TEN MAIN DISEASES OF CAUSED OF DEATH IN INDONESIA

11 Risks in 3 rd World n Lack of safe water supply n Contaminated foods n Poor sanitation n Overcrowding n Malnutrition

12 Global Risks in the World n Traveller Diarrhoea n HIV infection & immunosuppression n Day Care Centers: fomite spread –Also affects staff, household contacts n Nursing Home/Chronic Care Facilities n Antibiotics n Achlorhydria/H2 blocker

13 Factors in Emergencies n Lack of safe, clean water supply n Contamination of food supply n Poor sanitation n Overcrowding n Malnutrition n HIV infection & immunosuppression

14 Overall Significance n One of most common diseases in world n 3-5 billion cases of acute infectious diarrhea annually n Kills 5-10 million people/year n In the U.S., more than 8 million seek medical attention for diarrhea; costs $23 billion in medical expenses & lost wages

15 DIARRHEA Diarrhea is a common symptom that can range in severity from an acute, self-limited annoyance to a severe, life-threatening illness. Patients may use the term "diarrhea" to refer to increased frequency of bowel movements, increased stool liquidity, a sense of fecal urgency, or fecal incontinence

16

17 Definition διάρροια; literally meaning "through-flowing" Stool looses its normal consistence Weight usually increases: >235g/d ( ♂ ), >175g/d ( ♀ )‏ Frequency increases: >2/d Often associated with imperative urge to defecate Can contain blood, pus and mucous

18 Definition n In the normal state, approximately 10 L of fluid enter the duodenum daily, of which all but 1.5 L are absorbed by the small intestine. The colon absorbs most of the remaining fluid, with only 100 mL lost in the stool. From a medical standpoint, diarrhea is defined as a stool weight of more than 250 g/24 h

19 Input Absorption Diet/Saliva : 3 L/d Stomach : 2 L Bile : 1 L Pancreas : 2 L Bowel : 1 L Jejunum : 5 L/d Ileum : 2-3 L Colon : 1-2 L Fecal Water mL/d Thus, diarrhea is defined as >200 mL liquid excretion per day. In extremus, the gastrointestinal tract can both absorb and secrete 20 L of water per day. Total 9 L Total 8.8 L

20 ACUTE DIARRHEA n Diarrhea that is acute in onset and persists for less than 3 weeks is most commonly caused by infectious agents, bacterial toxins (either ingested preformed in food or produced in the gut), or drugs

21 Causes of acute infectious diarrhea 1. Viral - Norwalk virus, Norwalk-like virus, Rotavirus 2. Protozoal - Giardia lamblia, Cryptosporidium 3. Bacterial - Preformed enterotoxin production Staphylococcus aureus, Bacillus cereus, Clostridium perfringens Enterotoxin production; Enterotoxigenic E coli (ETEC), Vibrio cholerae

22 Other classifacation ViralProtozoan, Rota, adeno, enterovirus, Norwalk CMV, Rota, adeno, enterovirus, Norwalk, Giardia, Amy the Ameba, Cryptosporidium “Invasive”Toxicogenic/Secretory E. Coli 0157:H7, E. Coli 0157:H7, Shigella, Vibrios, Low-Backed Her, Salmonella, Vibrios, Campy Low-Backed Her, Staph, noninvasive E. Coli, Be Serious,, Cholera Staph, noninvasive E. Coli, Be Serious, C. Difficile, Cholera * lumps together invasive, inflammatory, non-amebic dysenteries, etc.

23 Pathogenesis Stimulation of net fluid secretion Mucosal destruction with increased permeability Nutrient malabsorption Increased propulsive contraction

24 Etiologic Agents n Toxin-producing bacteria n Invasive Bacteria n Parasites n Viruses

25 Toxin-producing bacteria n Cholera n Shigella n ETEC (enterotoxigenic E. Coli) n EHEC (Enterohemorrhagic/EC 0157 n Clostridium difficile n Bacillus cereus

26 Vibrio Cholera n Spread in water, undercooked seafood n Secretion of fluid in small intestine n Malabsorption of fluid in large intestine n Rice water stools—large volume, high electrolyte content n More info: CholeraCholera

27 Shigella n Spread by contaminated food, water n Bloody diarrhea characteristic n Fever common n Some carriers asmptomatic; symptoms usually occur in 2-3 days n More info: ShigellaShigella

28 ETEC (Enterotoxigenic EC) n Major cause of diarrhea in developing countries & travelers n Two toxins, one cholera-like n Causes watery diarrhea, nausea, cramps, low-grade fever n Rx: TMP-SMX or Bismuth salicylate n More info: ETECETEC

29 EHEC (Enterohaemorrhagic EC) n Toxin from undercooked food, especially beef n May be mild or asx, but fever, severe cramps & bloody diarrhea common n Cause of hemolytic uremic syndrome n More info: EHEC-O157EHEC

30 C. difficile n Antibiotics facilitate overgrowth of normal bowel inhabitant n Watery diarrhea +/- blood, cramps, fever n Treatment: oral vancomycin or Flagyl n More info: C. difficileC. difficile

31 Invasive Bacteria n EIEC (enteroinvasive E. coli) n Salmonella n Campbylobacter n Yersinia

32 Enteroinvasive E. coli n Symptoms mimic Shigella: bloody diarrhea, fever, cramps n Thought to be spread by food contamination n Therapy supportive, usually self-limited without requiring antibiotics n More info: EIECEIEC

33 Salmonella n Contaminates raw eggs, dairy products, poultry, other meats n Fever, diarrhea, +/- vomiting, can enter bloodstream n More common in children, in summer n More info: SalmonellaSalmonella

34 Enteric Fever n A severe systemic illness manifested initially by prolonged high fevers, prostration, confusion, respiratory symptoms followed by abdominal tenderness, diarrhea, and a rash is due to infection with Salmonella typhi or Salmonella paratyphi, which causes bacteremia and multiorgan dysfunction

35 Campylobacter n Spread by contaminated water or raw milk n Causes patchy destruction of walls of small and large intestines n Diarrhea +/- blood, fever, vomiting, HA, abd pain n More info: CampylobacterCampylobacter

36 Yersinia n Contaminates dairy products, poultry, & other meat n Multiple syndromes, including sepsis in immunosuppressed; appendicitis-like; fever/diarrhea/abd pain in children; & extra-intestinal infections n More info: YersiniaYersinia

37 Parasites n Giardia lamblia n Entamoeba histolytica n Cryptosporidium

38 Giardia n Zoonosis, animals contami- nated Water n Diarrhea, abdominal pain, gas n Treat w/ Flagyl

39 Entamoeba histolytica n Diarrhea, often Bloody, fever, abd cramps n Onset usually 2-4 wks, range days-mos n Treat w/ Flagyl n More info: AmoebaAmoeba

40 Cryptosporidium n Watery diarrhea, emesis, cramps, fever n Transmitted in water or fecal-oral n More pathogenic in immunosupressed, especially AIDS n Best treatment is restoring immune fn, (e.g., several drugs for HIV), azithromycin shows some efficacy n More info: CryptosporidiumCryptosporidium

41 Viruses n Rotavirus n Norwalk Agent n Calciviruses

42 Rotavirus Epidemiology n Most common cause of acute gastro- enteritis in children worldwide n Infects almost all children by age 4 n Kills nearly one million annually n Fecal-oral transmission, lasts for days on toys & countertops n More common in winter

43 Rotavirus features n Ranges from asymptomatic to severe n 3-9 days’ fever, abd. pain, diarrhea n Wheel-shaped RNA virus, seen in stool on EM, or diagnosed by ELISA n Prevent w/ handwashing & hygiene n Rx severe cases w/ ORS or IV fluids n More info: RotavirusRotavirus

44 Calciviruses n Known as Norwalk-like viruses—small, single-stranded RNA viruses n Associated with ingestion of raw shellfish, fecal-oral transmission n Cause diarrhea, vomiting, fever, headache

45 DIAGNOSTIC APPROACH n Often based on clinical grounds alone –Diagnostic studies often unavailable –Symptoms often resolve, or require prompt treatment, before results can be obtained –Clinical features that may be helpful include exposure/risk factors; stool volume, presence of blood, associated symptoms

46 DIAGNOSTIC STUDIES If available, may include: n Fecal leukocytes n Stool culture n Ova and parasites n C. difficile titer n Amoeba titers

47 MANAGEMENT OF DIARRHOAE n Treatment often empiric n Oral rehydration therapy (ORT) n IV hydration n Anti-diarrheals: anti-motility, absorbent, and anti-secretory agents n Antibiotics

48 Oral Rehydration n Safe, simple, cheap n 1 st use: Bangladesh, 1971—dramatic reduction in mortality n Premix, or use H2O, salt, sugar n Treats and prevents diarrhea n Sodium-glucose co-transport n Mothers can administer ORT

49 Oral Rehydration n Glucose-based ORT may paradoxically increase fecal fluid loss n Rice-based ORT may more quickly relieve symptoms, ? More available n High amylose maize (amylase-resistant) based ORT shortens diarrhea duration and reduces stool volume

50 Indications for IV hydration n Severe dehydration (hypotension, shock, stupor, coma) n Ileus—abd distention a/o absent BS n Persistent severe vomiting n Excessive stool output (10cc/kg/hr) n Severe glucose malabsorption

51 More on IV hydration n Replace fluid deficit as well as continuing losses n Transition to ORT as soon as dehydration improves and/or gut seems to be working again

52 Antimotility Agents n Increase segmental & decrease propulsive contractions n Prolong transit time n Loperamide better than diphenoxylate in clinical trials n Opiates have similar effect on motility n Limit to 48 hours; may prolong illness & can cause ileus or toxic megacolon

53 Absorbent agents n Nonabsorbable resins, e.g. cholestyramine n Bind C. difficile toxin n Speed toxin clearance, promote mucosal recovery—for multiple pathogens n Stop 5 days after symptoms resolve

54 Antisecretory agents n Decrease propulsive contractions n Increase mucosal absorption n Decrease mucosal secretion n Enhance electrolyte & H20 reabsorption n Most useful in AIDS-associated diarrhea n Ex.: octreotide

55 Antibiotics in Diarrhoae n Not indicated for most cases of simple, watery diarrhea n Most helpful for: –Shigella, ETEC, ameobiasis, giardia, cholera, S. typhi –May help for cryptosporidium, other salmonella –Not useful for viral, EIEC

56 Special treatment of cholera n Oral Rehydration Therapy n Antibiotics –Limit spread of disease by reducing volume & duration of diarrhea –Adults: Doxycycline, 300 mg once –Children: 6 mg/kg once –Alternatives: TTC, Chloramphenicol, Septra, quinolones, erythromycin

57 n Applying the principle of hygiene n Depend of the improvement of income n Cultural changes of personal hygiene n Many effort for control of TF, are : (1) Treatment and control of sources infection : Adequate antibiotic treatment for active patients and carriers, special isolation in the hospital ?, desinfections of the excreta, sterilization of the patient’s linen etc. CONTROL OF ENTERIC FEVER

58 n (2) Improved on environment health. To trace the source infection. To investigate of routes transmis. Water purification/chlorination. Control of all exposed foods for sale in the market and store.. Reduction the house-flies density. To avoid of having open garbage pail etc. CONTROL OF ENTERIC FEVER

59 n (3) Supervision on food industries and restaurant. Supervision on sanitation of places work and food processin, equipment etc.. Prohibition to employ people who infected. Routine examination of stool culture. To trace of food, if as medium suspected. All milk and milk products should be pasteurized or boiled. CONTROL OF ENTERIC FEVER

60 n (4) Control of healthy population. Supervision on hygiene of food and drink. Serving the food in hot condition. Health education for community. Providing the places for washing hand. Conducting vaccination of EF in endemic area, however, improvement of sanitation and health system is very important role. CONTROL OF ENTERIC FEVER

61 Choose foods processing for safety. n Cook food thoroughly. n Eat cooked food immediately. n Store cooked food thoroughly. n Reheat cooked food thoroughly. n Avoid contact between raw and cooked foods. n Wash hands repeately. n Keep all kitchen surfaces meticolously clean. n Protect foods from insects, rodents & animals. n Use pure water. THE WHO GOLDEN RULES FOR SAVE FOOD PREPARATION

62 NO DISEASE ASYMPTOMA TIC DISEASE CLINICAL COURSE ONSET ORDINARY DETECTION LEVEL OF PREVENTION PRIMARY Remove of risk factors SECONDARY Early detec- tion & prompt treatment TERTIARY Reduce complications PREMORD Underlying risk factors

63 n Diarrheal disease most prevalent in developing countries, and costly. n In Indonesia incidence still high. n Transmission most of direct route. n Empiric treatment with ORT most often effective n The strategies of Diarrhea Control SUMMARY OF DIARRHEA CONTROL

64 The strategies of Diarrhea Contro l are :. Detection and control of source,. Disease surveillance,. Health education in community,. Improvement of hygiene sanitation,.
