Communicable Disease Nursing

I. EPI DISEASES DISEASE 1. Tuberculosis Other names: Koch’s Disease Consumption Phthisis Weak lungs

CAUSATIVE AGENT Mycobacterium tuberculosis TB bacillus Koch’s bacillus Mycobacterium bovis (rod-shaped)

MODE OF TRANSMISSION Airborne-droplet Direct invasion through mucous membranes and breaks in the skin (very rare)

Most hazardous period for development of clinical Incubation period : 4 – 6 weeks disease is the first 6-12 months after infection Highest risk of developing disease is children under 3years old

PATHOGNOMONIC SIGN 1. Usually asymptomatic 2. Low-grade afternoon fever 3. Night sweating 4. Loss of appetite 5. Weight loss 6. Easy fatigability – due to increased oxygen demand 7. Temporary amenorrhea 8. Productive dry cough 9. Hemoptysis

TREATMENT: SCC/Short Course Chemotherapy, Direct –observed treatment short course/DOTS; Rifampicin (R), Isoniazid (H), Pyrazinamide (Z), Ethambutol (E), Streptomycin (S) CATEGORY 1: 6 months SCC Indications: > new (+) smear > (-) smear PTB with extensive parenchymal lesions on CXR > Extrapulmonary TB > severe concominant HIV disease Intensive Phase: 2 months R&I : 1 tab each; P&E 2 tabs each Continuation Phase: 4 months R&I : 1 tab each

CATEGORY 2: 8 months SCC Indications: > treatment failure > relapse > return after default Intensive Phase:3 mos R&I 1 tab each; P&E 2 tabs each Streptomycin – 1 vial/day IM for first 2 months = 56 vials (if given for > 2mos can cause nephrotoxicity Continuation Phase: 5 months R&I : 1 tab each E : 2 tabs

CATEGORY 3: 6 months SCC Indications: > new (-) smear PTB with minimal lesions on CXR Same meds with Category 1 Intensive Phase: 2 months R&I 1 tab each; P&E 2 tabs each Continuation Phase: 4 months R&I 1 tab each CATEGORY 4: Chronic (*Referral needed)

SIDE EFFECTS: Rifampicin • body fluid discoloration • hepatotoxic • permanent discoloration of contact lenses Isoniazid • Peripheral neuropathy (Give Vit B6/Pyridoxine) Pyrazinamide • hyperuricemia /gouty arthritis (increase fluid intake)

MANAGEMENT/TREATMENT

PREVENTION

Diagnostic test: • Sputum examination or the Acid-fast bacilli (AFB) / sputum microscopy 1. Confirmatory test 2. Early morning sputum about 3-5 cc 3. Maintain NPO before collecting sputum 4. Give oral care after the procedure 5. Label and immediately send to laboratory 6. If the time of the collection of the sputum is unknown, discard • Chest X-ray is used to: 1. Determine the clinical activity of TB, whether it is inactive (in control) or active (ongoing) 2. To determine the size of the lesion: a. Minimal – very small b. Moderately advance – lesion is < 4 cm c. Far advance – lesion is > 4 cm • Tuberculin Test – purpose is to determine the history of exposure to tuberculosis Other names: Mantoux Test – used for single screening, result interpreted after 72 hours Tine test – used for mass screening read after 48 hours Interpretation: 0 - 4 mm induration – not significant 5 mm or more – significant in individuals who are considered at risk; positive for patients who are HIV-positive or have HIV risk factors and are of unknown HIV status, those who are close contacts with an active case, and those who have chest x-ray results consistent with tuberculosis. 10 mm or greater – significant in individuals who have normal or mildly impaired immunity

• Respiratory precautions • Cover the mouth and nose when sneezing to avoid mode of transmission • Give BCG BCG is ideally given at birth, then at school entrance. If given at 12 months, perform tuberculin testing (PPD), give BCG if negative. • Improve social conditions SIDE EFFECTS: Ethambutol • Optic neuritis • Blurring of vision (Not to be givento children below 6 y.o. due to inability to complain blurring of vision) • Inability to recognize green from blue Streptomycin • Damage to 8th CN • Ototoxic • Tinnitus • nephrotoxic

V. VECTOR-BORNE DISEASES DISEASE 1. Malaria

CAUSATIVE AGENT Plasmodium Parasites: Vivax Falciparum (most fatal; most common in the Philippines) Ovale Malariae -attacks the red blood cells

MODE OF TRANSMISSION Bite of infected anopheles mosquito Night time biting High-flying Rural areas Clear running water

PATHOGNOMONIC SIGN Cold Stage: severe, recurrent chills (30 minutes to 2 hours) Hot Stage: fever (4-6 hours) Wet Stage: Profuse sweating Episodes of chills, fevers, and profuse sweating are associated with rupture of the red blood cells. - intermittent chills and sweating - anemia / pallor - tea-colored urine - malaise - hepatomegaly - splenomegaly - abdominal pain and enlargement - easy fatigability NURSING CARE: 1. TSB (Hot Stage) 2. Keep patent warm (Cold Stage) 3. Change wet clothing (Wet Stage) 4. Encourage fluid intake 5. Avoid drafts


PREVENTION

Early Diagnosis and Prompt Treatment Early diagnosis – identification of a patient with malaria as soon as he is seen through clinical and/or microscopic method Clinical method – based on signs and symptoms of the patient and the history of his having visited a malaria-endemic area Microscopic method – based on the examination of the blood smear of patient through microscope (done by the medical technologist)

*CLEAN Technique *Insecticide – treatment of mosquito net *House Spraying (night time fumigation) *On Stream Seeding – construction of bio-ponds for fish propagation (2-4 fishes/m2 for immediate impact; 200-400/ha. for a delayed effect) *On Stream Clearing – cutting of vegetation overhanging along stream banks

QBC/quantitative Buffy Coat – fastest Malarial Smear – best time to get the specimen is at height of fever because the microorganisms are very active and easily identified Chemoprophylaxis Only chloroquine should be given (taken at weekly intervals starting from 1-2 weeks before entering the endemic area). In pregnant women, it is given throughout the duration of pregnancy. Treatment: Blood Schizonticides - drugs acting on sexual blood stages of the parasites which are responsible for clinical manifestations 1. QUININE – oldest drug used to treat malaria; from the bark of Cinchona tree; ALERT: Cinchonism – quinine toxicity 2. CHLOROQUINE 3. PRIMAQUINE – sometimes can also be given as chemoprophylaxis 4. FANSIDAR – combination of pyrimethamine and sulfadoxine

*Avoid outdoor night activities (9pm – 3am) *Wearing of clothing that covers arms and legs in the evening *Use mosquito repellents *Zooprophylaxis – typing of domestic animals like the carabao, cow, etc near human dwellings to deviate mosquito bites from man to these animals Intensive IEC campaign

VI. DISEASES TRANSMITTED BY ANIMALS DISEASE 1. Leptospirosis Other Names: - Weil’s Disease - Mud Fever - Trench Fever - Flood Fever - Spirochetal Jaundice - Japanese Seven Days fever

2. Rabies Other Names: Lyssa Hydrophobia Le Rage

CAUSATIVE AGENT Leptospira interrogans – bacterial spirochete RAT is the main host. Although pig, cattle, rabbits, hare, skunk, and other wild animals can also serve as reservoir Occupational disease affecting veterinarians, miners, farmers, sewer workers, abattoir workers, etc

MODE OF TRANSMISSION Through contact of the skin, especially open wounds with water, moist soil or vegetation infected with urine of the infected host Incubation Period: 7-19 days, average of 10 days

Bite or scratch (very rare) of rabid animal

Degeneration and necrosis of brain – formation of negri bodies

Non-bite means: leaking, scratch, organ transplant (cornea), inhalation/airborne (bats) Source of infection: saliva of infected animal or human

b. Sylvatic – disease of wild animals and bats which sometimes spread to dogs, cats, and livestock

MANAGEMENT/TREATMENT Diagnosis Clinical manifestations Culture of organism Examination of blood and CSF during the first week of illness and urine after the 10th day Leptospira agglutination test Treatment: Penicillins and other related B-lactam antibiotics Tetracycline (Doxycycline) Erythromycin Most common complication: kidney failure

Rhabdovirus of the genus lyssavirus

Two kinds of Rabies: a. Urban or canine – transmitted by dogs

PATHOGNOMONIC SIGN Leptospiremic Phase - leptospires are present in blood and CSF - onset of symptoms is abrupt - fever - headache - myalgia - nausea - vomiting - cough - chest pain

Incubation period: 2 – 8 weeks, can be years depending on severity of wounds, site of wound as distance from brain, amount of

Immune Phase - correlates with the appearance of circulating IgM Sense of apprehension Headache Fever Sensory change near site of animal bite Spasms of muscles of deglutition on attempts to swallow Fear of water/hydrophobia Paralysis Delirium Convulsions “FATAL once signs and symptoms appear”

Diagnosis: history of bite of animal culture of brain of rabid animal demonstration of negri bodies Management: *Wash wound with soap immediately. Antiseptics e.g. povidone iodine or alcohol may be applied *Antibiotics and anti-tetanus immunization *Post exposure treatment: local wound treatment, active immunization (vaccination) and passive immunization (administration of rabies immunoglobulin) *Consult a veterinarian or trained personnel to observe the pet for 14 days *Without medical intervention, the rabies victim would usually last only for 2 to 6 days. Death is

PREVENTION Protective clothing, boots and gloves Eradication of rats Segregation of domestic animals Awareness and early diagnosis Improved education of people Avoid wading or swimming in water contaminated with urine of infected animals. Concurrent disinfection of articles soiled with urine. Have pet immunized at 3 months of age and every year thereafter Never allow pets to roam the streets Take care of your pet National Rabies Prevention and Control Program Goal: Human rabies is eliminated in the Philippines and the country is declared rabiesfree

BCG vaccination – practical and effective preventive measure against leprosy

Adequate nutrition Health education

MDT Facts: It reduces communicability period of leprosy in 4-6 weeks time. It prevents development of resistance to drugs. It shortens the duration of treatment.

MULTIBACILLARY (lepromatous and borderline); infectious type Duration of treatment: 24-30 months Procedure: Supervised: Rifampicin, Dapsone, and Lamprene
