Acute Communicable Disease Control Manual (B-73)REVISION—FEBRUARY 2013ANAPLASMOSIS(formerly termed ehrlichiosis; human granulocytic ehrlichiosis [HGE])1. Agent: Anaplamosis is caused by Anaplasmaphagocytophila, an ehrlichial organismformerly known as Ehrlichia phagocytophila, E.equi.2. Identification:a. Symptoms:Humanehrlichiosis/anaplamosis are newly recognizeddiseases in USA. The spectrum of diseaseranges from mild illness to a severe, lifethreatening or fatal disease. Symptoms areusually nonspecific; the most commoncomplaints are fever, headache, anorexia,nausea, myalgia and vomiting. The diseasemay be confused clinically with RockyMountain spotted fever (RMSF) but differsby rarity of a prominent rash.Laboratory findings include leukopenia,thrombocytopenia, and elevation of one ormore liver-function tests. In hospitalizedcases, the laboratory findings may be onlyslightly abnormal on admission, andbecomemoreabnormalduringhospitalization.b. Differential Diagnosis: RMSF, bacterialsepsis, Lyme disease, endemic (murine)typhus, toxic-shock syndrome, gastroenteritis, viral syndromes, tick-borneencephalitis and other multi-system febrileillnesses.c. Diagnosis: Preliminary diagnosis ofehrlichiosis/anaplamosis in the USA isbased on clinical and laboratory findings.Confirmation is based on: the evaluation ofa blood smear, development of serumantibodies to E. chaffeensis for ehrlichiosisor A. phagocytophila for anaplamosis;immunofluorescence test; PCR.3. Incubation: 7 to 21 days forehrlichiosis/anaplamosis.4. Reservoir: White-tailed deer are a major hostof lone star ticks and appear to represent onenatural reservoir for E. chaffeensis. Deer, elk,and wild rodents are likely reservoirs of theagent of HGE.5. Source: Ehrlichiosis/anaplamosis in NorthAmerica has been concentrated in thesoutheastern and south-central areas of theUSA. More than 12 human cases, including 3deaths, caused by a granulocytic Ehrlichia,have occurred in northern Minnesota,Wisconsin, Connecticut, Maryland and Florida.Rarely cases of ehrlichiosis/anaplamosis havebeen diagnosed in California.6. Transmission: In the United States, ehrlichiaeare transmitted by the bite of an infected tick.The lone star tick (Amblyomma americanum),the blacklegged tick (Ixodes scapularis), andthe western blacklegged tick (Ixodes pacificus)are known vectors of ehrlichiosis/anaplamosisin the US. Ixodes ricinus is the primary vectorin Europe. Most patients report a tick bite orassociation with wooded, tick-infested areas1prior to onset of illness.7. Communicability: No evidence of person-toperson transmission.8. Specific Treatment: A tetracycline such asdoxycycline; chloramphenicol for pregnantwomen and children under 8 years of age.9. Immunity: Susceptibility is believed to begeneral. No data are available on protectiveimmunity in humans from infections caused bythese organisms. Re-infection is rare but hasbeen reported.REPORTING PROCEDURES1. Reportable within 7 days of diagnosis (Title 17,Section 2500, California Code of Regulations).2.

Acute Communicable Disease Control Manual (B-73)REVISION—OCTOBER 2011ANISAKIASIS1. Agent: Larval nematodes of the subfamilyAnisa-kinae, genera Anisakis, andPseudoterranova.2. Identification: A parasitic disease of thehuman gastrointestinal tract usually manifestedby cramping, abdominal pain and vomiting,resulting from the ingestion of uncooked orunder treated marine fish containing larvalnematodes. The motile larvae burrow into thestomach wall producing acute ulceration withnausea, vomiting and epigastric pain,sometimes with hematemesis. They maymigrate upward and attach in the oropharynx,causing cough. In the small intestine, theycause eosinophilic abscesses, and thesymptoms may mimic appendicitis or regionalenteritis. At times they perforate into theperitoneal cavity; they rarely involve the largebowel. Diagnosis is made by recognition of the2 cmlong larva invading the oropharynx or byvisualizing the larva by gastroscopicexamination or in surgically removed tissue.3. Incubation period: Gastric symptoms maydevelop within a few hours after ingestion.Symptoms referable to the small and largebowel occur within a few days or weeks,depending on the size and location of larvae.4. Reservoir: Anisakinae are widely distributed innature, but only certain of those that areparasitic in sea mammals constitute a majorthreat to humans. The natural life cycleinvolves transmission of larvae by predationthrough small crustaceans to squid, octopus orfish, then to sea mammals, with humans asincidental hosts.5. Source: The disease occurs in individuals whoeat uncooked and inadequately treated(frozen, salted, marinated, smoked) saltwaterfish, squid or octopus. This is common inJapan (sushi and sashimi), the Netherlands(herring), Scandinavia (gravlax) and LatinAmerica (ceviche).6. Transmission: The infective larvae live in theabdominal mesenteries of fish; often afterdeath of their host they invade the bodymuscles of the fish. When ingested by peopleand liberated by digestion in the stomach, theymay penetrate the gastric or intestinal mucosa.7. Communicability: Direct transmission fromperson to person does not occur.8. Specific Treatment: Gastroscopic removal oflarvae; excision of lesions.9. Immunity: None.REPORTING PROCEDURES1. Reportable: (Title 17, Section 2500, CaliforniaCode of Regulations). Report within 1 workingday of identification of a case or suspectedcase.2. Report Form: OUTBREAK / UNUSUALDISEASE REPORT (CDPH 8554) Ifanisakiasis infection is associated with afoodborne illness, see also foodborne illnessreporting.

Acute Communicable Disease Control Manual (B-73)REVISION—OCTOBER 2011CONTROL OF CASE, CONTACTS & CARRIERSCASE: No restrictions.CONTACTS: Examination of others possiblyexposed at the same time may be productive.PREVENTION-EDUCATION1. Avoid ingestion of inadequately cooked marinefish. Heating to 60 "C (140 "F) for 10 minutes,blast-freezing to -35 "C (-31 "F) or below for 15hours or freezing by regular means at -23 "C(10 "F) for at least 7 days kills the larvae.Irradiation effectively kills the parasite.2. Cleaning (evisceration) of fish as soon aspossible after they are caught reduces thenumber of larvae penetrating into the musclesfrom the mesenteries.DIAGNOSTIC PROCEDURESConsult Public Health Laboratory, ParasitologySection.PART IV: Acute Communicable DiseasesANISAKIASIS — page 2

Acute Communicable Disease Control Manual (B-73)REVISION—MARCH 2014BOTULISM(See also INFANT BOTULISM and WOUNDBOTULISM, below.)1. Agent: Toxin produced by Clostridiumbotulinum (and rarely other clostridiumspecies), a gram-positive bacillus. Mostcases due to type A, B or E toxin. Heat-labiletoxin is produced under anaerobic nsically in the gastrointestinal tract(intestinal botulism, infant botulism) or wound(wound botulism).2. Identification:a. Symptoms: An intoxication characterizedby weakness, extreme dryness of themouth, headache and constipation(although vomiting and diarrhea mayoccur), followed by symmetrical cranialnerve motor paralysis, ptosis, visualdifficulty, and descending paralysis.Severity appears dose related.Death may occur from respiratory failureor superimposed infections.b. Differential Diagnosis: Guillain-Barrésyndrome (Miller-Fisher variant),myasthenia gravis, cerebrovascularaccident, tick paralysis, neoplasia, orchemical intoxication.c. Diagnosis: Demonstration of toxin infeces or serum of the patient or in a suspected food item. Isolation of theorganism from feces, wound, orsuspected food is indicative of source.3. Incubation period: Usually within 12-36hours of eating contaminated food, but mayoccur several days afterward. Woundbotulism occurs within days of injury.4. Reservoir: C. botulinum spores in soil,water, and the intestinal tracts of animals,including fish.5. Source: Toxins are produced by C.botulinum and rarely other clostridiumspecies under anaerobic conditions, usuallyby improperly home-canned foods, especiallylow acid food, corn, beans; baked potato ormishandled foods that should have beenrefrigerated. Also in contaminated, closedwounds, similar to tetanus (C. tetani).6. Transmission: Ingestion of toxin orproduction of toxin in infected wound or GItract.7.
