SCHISTOSOMIASIS Flashcards
caused by some species of blood flukes in the
genus Schistosoma.
SCHISTOSOMIASIS
OTHER TERM
§ Bilhariasis
§ Snail fever
§ Katayama fever
CLASSIFICATION:
Parasite
What is the intermediate host responsible for transmitting Schistosomiasis, and what is the infective stage that is released into the water by this host?
Schistosomiasis is transmitted by a tiny snail called ONCOMELANIA QUADRASI, which serves as the intermediate host. The infective stage released into the water by this snail is called CERCARIA.
SCHISTOSOMIASIS
CAUSED BY BLOOD FLUKES OF 3 TYPES
- Schistosoma mansoni
- Schistosoma japonicum
- Schistosoma haematobium
This BLOOD FLUKES Infects the GI tract
Schistosoma mansoni
This BLOOD FLUKES is Endemic in the PH
Schistosoma japonicum
This BLOOD FLUKES Infects the GU tract
Schistosoma haematobium
SCHISTOSOMIASIS incubation period
IP: 2-6 weeks after exposure
How is Schistosomiasis primarily [MOT] transmitted to humans, and which STAGE of the parasite is responsible for infecting individuals?
Answer:Direct contact with contaminated fresh water
Schistosomiasis is primarily transmitted to humans through DIRECT CONTACT with contaminated fresh water, such as bathing, swimming, wading, or washing.
The free-swimming larval forms CERCARIAE) of the parasite are responsible for penetrating the skin during these activities.
SCHISTOSOMIASIS
S/SX
“Inside Free Flowing Dark Abyss.”
Inside (I): Initially, transient pruritic rash/ “swimmers itch”
Free (F): Fever
Flowing (F): Diarrhea
Dark (D): Bloody stools
Abyss (A): Abd. Pain (liver/spleen area)
SCHISTOMIASIS
LATE SIGNS
“Another Abdomen Have Slowly Lurk.”
“Another (A): Anemia (infects the liver)
Abdomen (A): Abd. Enlargement
Have (H): Hepatomegaly (invades the liver)
Slowly (S): Splenomegaly
Lurk (L): Lymphadenopathy”
SCHISTOSOMIASIS DX TEST
Fecal smears / Kato Katz method

SCHISTOSOMIASIS
NURSING INTERVENTIONS
o TSB
o Skin care
o Provide comfort
o Proper nutrition
SCHISTOSOMIASIS
PREVENTION AND CONTROL
“Rummaging Snails, Posing , Clinging, Safe,or For Harm,”
o Reduce snail density
§ Molluscicides
§ Stream Cleaning Vegetation (expose the snails
to sunlight)
o Proper waste disposal
o Control of stray animals
o Safe and adequate water supply for bathing,
laundering and drinking
o Foot bridges over snail-infested streams
o Health education about mode of transmission and
prevention
