- Avoidance of prolonged skin to skin contact especially with lepromatous case
- Children should avoid close contact with active untreated leprosy case 3. BCG vaccine
- Practice personal hygiene
- Adequate nutrition, rest, and exercise
Prevention and Control
LEPROSY
● Ambulatory chemotherapy through use of MDT
● Multi-Drug Therapy it is use of 2 or more drugs for the treatment of leprosy.
● Combination: Rifampicin, clofazimine, *Dapsone (Sulfones) for
Multibacillary (MB) leprosy patients
● Other drugs: minocycline, clarithromycin, and some fluoroquinolones
Treatment
● An acute bacterial infection of the intestine characterized by diarrhea, fever, tenesmus and in severe cases bloody mucoid stools.
● Severe infections are frequent in infants and in elderly debilitated persons

given in two doses and offers protection for 3 years.
● Other preventive measures are the same as those of Typhoid and Dysentery
Prevention and Control
CHOLERA (El Tor)

SOIL TRANSMITTED HELMINTHIASIS (STH)
The three major causes of intestinal parasitic in the Philippines are:
● Ascaris lumbricoides (Giant intestinal roundworm)
● Trichuris trichiura (Whipworm)
● Hookworm: Ancyclostoma duodenale (Old world hookworm) and Necator americanus ( New world hookworm)

Mode of Transmission
SOIL TRANSMITTED HELMINTHIASIS (STH)
● Anemia
● Malnutrition
● Stunted growth in height and body size
● Decreased physical activities
● Impaired mental and school performance
Signs and symptoms
SOIL TRANSMITTED HELMINTHIASIS (STH)
- Health education
a. Good personal hygiene
b. Keeping fingernails short and clean
c. Use footwear
d. Use sanitary facilities like toilets
e. Sanitary disposal of feces - Early diagnosis and treatment
a. Laboratory examination of stool (fecalysis)
b. Ensure proper dosage of medication and completion of treatment
Prevention and Control
SOIL TRANSMITTED HELMINTHIASIS (STH)
● Drugs such as Piperazine citrate, pyrantel pamoate, mebendazole, albendazole, and levimazole can be administered depending on what parasite is present.
Treatment
● One of the important tropical disease in our country.
● Since it affects mostly farmers and their families in the rural area it results in manpower losses and lessened
agricultural productivity.
● There is a high prevalence of Schistosomiasis in Region 5 (Bicol). Region 8 (Samar and Leyte) and Region 11
(Davao)
SCHISTOSOMIASIS (Bilhariasis or snail fever)
SCHISTOSOMIASIS (Bilhariasis or snail fever)
Oncomelania hupensis quadrasi
Intermediate Host
SCHISTOSOMIASIS (Bilhariasis or snail fever)
● Infection occurs when the skin comes in contact with contaminated fresh water in which certain types of snails that carry Schistosomes are living. It is a free-swimming larval form (cercaria) of the parasites that penetrates the skin. Fresh water becomes contaminated when infected people urinate or defecate in water.
Mode of Transmission
SCHISTOSOMIASIS (Bilhariasis or snail fever)
● Diarrhea (bloody stool or urine)
● Enlargement of abdomen
● Splenomegaly
● Weakness
● Anemia
● Inflamed liver
Signs and Symptoms
SCHISTOSOMIASIS (Bilhariasis or snail fever)
- Preventive measures
a. Educate the public in endemic areas regarding the mode of transmission and methods of protection
b. Proper disposal of feces and urine
c. Improve irrigation and agricultural practices: reduce snail habitats by removing vegetation
d. Treat snail breeding sites with molluscicides
e. Prevent exposure to contaminated water
f. Provide water for drinking, bathing and washing clothes from sources free of cercaria or treatment to kill them. hTravelers visiting in endemic area should be advised of the risk and informed - Control of patient contacts and the environment
a. Report to local health authority
b. No need for isolation and quarantine to infected people and those who are at risk c. Concurrent disinfection; sanitary disposal of feces and urine - Investigation of contact and source of infection
a. Epidemic measure: examine for schistosomiasis and treat all who are infected but especially those with moderate to heavy infection, pay particular to children
b. Motivate people in these areas to have annual stool exam
