    Discovered in 1851 by the German physician Theodor Bilharz

    What is Schistosomiasis?

    Also known as Snail Fever and Bilharzia this is a disease caused by parasitic flatworms

    called schistosomes. The urinary tract or the intestines may be infected.Those who have been infected for a long time may experience liver damage, kidney failure, infertility, or bladder cancer. In children, it may cause poor growth and

    learning difficulty. https://en.wikipedia.org/wiki/Schistosomiasis

    Where is Schistosomiasis found?

    Schistosomiasis is found all over the world usually in developing countries from the Tropics. Thinking of it as a disease of Africa is not correct though; as the world has gotten smaller due to intercontinental flights and migrations. Many years ago we saw it spread following the trade routes of the 1800's today its only as far as your next airplane ticket or local waterway. There are reports of it showing up in fresh waterways in southern France and even the Caribbean islands, think about that the next time you book a holiday. The highest levels of schistosome transmission are in communities living near freshwater lakes and rivers.
    Around 240 million people worldwide have it and more than 200,000 deaths per year are a result of schistosomiasis.


    Schistosomiasis is now being found in first world countries such as the US and UK from persons with no travel history to endemic countries.

    How is Schistosomiasis transmitted?

    Individuals get infected when they come into contact with fresh water contaminated with the schistosome parasite. Fresh water becomes contaminated with the parasite when individuals infected with schistosomiasis urinate or defecate in the water, releasing the parasite’s eggs, which later hatch.The parasite larvae then develop and multiply inside specific types of freshwater snails, before re-entering the water. Then it can survive for up to 48 hours in the water as it swims around looking for a human host to infect.


    Recent developments have revealed that Schistosomiasis can be transmitted sexually between partners. Testing is underway and results are coming in of both partners being infected with Schistosomiasis.

    How does it affect you?

    When the schistosome parasite finds a host in the water, it burrows into your skin where it typically will leave red bumps or a swimmers like rash. After this it makes its way to the capillaries entering into the circulatory system stopping first in the lungs. After that phase the parasite changes into a small worm like parasite and starts to move to your liver. Once in your liver the parasite goes through its final phase and becomes an adult worm where it moves again settling into its residence either the blood vessels located around your bladder (Haematobium)or the blood vessels around your intestines (Mansoni). Once there is when the real damage starts to take place, eggs. Now that the worm is in its adult form it finds a mate and they begin to produce thousands of eggs a day. The eggs migrate through the attaching tissue into either the bladder or intestines to be expelled by the human host and hence perpetuate the cycle all over again. This is where the true damage of the disease takes place as the eggs irritate the linings and cause inflammation. Some of the eggs will be trapped due to your bodies natural defenses and cysts will form that later can develop into cancer. Frequent urination and or frequent deification of loose or floating stool is a strong symptom of schistosomiasis. Why floating? Floating is what the parasites have evolved to do as human host are more likely accessible at the surface of fresh waters.


    In STD transmissions the first signs of it show up as an UTI with frequent urination and malaise. If left untreated the more severe and associated schistosomiasis symptoms appear.


    If you suffer from IC (Interstitial cystitis) or painful bladder syndrome there is a good chance that it is Schistosomiasis.

    Symptoms of Schistosomiasis

    • A red rash or bumps on the skin from being exposed to infected water (usually visible in 12 hours after exposure)
    • If contracted sexually symptoms show in 24-72 hours after exposure with frequent urination similar to an UTI. 
    • 2 to10 weeks later the following symptoms can appear
    • Chest pain – this is the result of larval parasites moving though the lung tissue and later schistosome eggs becoming trapped in the blood vessels that supply the lungs.
    • Dry cough
    • Palpitations 
    • Fatigue
    • Poor quality of sleep
    • Malaise
    • GERD or acid reflux
    • Frequent loose or floating stools after eating.
    • Diarrhea – schistosome eggs can lodge in the blood vessels of the intestine causing inflammation resulting in bloody diarrhea or diarrhea.
    • Constipation 
    • Joint pain
    • Headache
    • Neck pain
    • Frequent urination of clear urine (every 2 hours)
    • Constant urge to urinate even after evacuating bladder
    • Pain when urinating – schistosome eggs lodged in the urinary tract cause inflammation and blood in the urine resulting in symptoms similar to urinary tract and bladder infections.
    • Blood in urine
    • Burning or stinging after urinating
    • Urine containing thin black threads
    • Dyspareunia (pain during intercourse ) 
    • Vagina pain 
    • Vaginal discharge (thick white fluid)
    • Kidney pain
    • Bladder pain 
    • Low Seminal fluid or semen 
    • Yellow chunks in sperm
    • Hemospermia (blood in sperm) 
    • Burning after ejaculation 
    • All symptoms come and go as this is a chronic disease, usually on a 6 week cycle 
    • Sometimes acute schistosomiasis symptoms can be so mild they go unnoticed
    • If left untreated death rate is about 200,000 people per year
    • Bladder cancer specifically with Schistosomiasis Haematobium


    Schistosomiasis haematobium - mansoni- japonica - mekong: Clinically treated with Praziquantel 60mg/kg/dailty orally in 3 divided doses for 1 day.



    Artemether (6 mg/kg), which is well known for its antimalarial activity, kills schistosomula during the first 21 days in the body.


    Herbal Relief

    Woodworm combinations with Green Walnut and Cloves: This really helped me expel a lot of worms and especially the eggs and larval form of Schistosomiasis. It worked on the Schistosomiasis and forced out tapeworms, hookworms, threadworms.


    Oregano Oil: Essential oil of oregano has shown to be effective against Schistosomiasis symptoms. This essential oil is known for its antiviral, antibacterial, anti-parasitic, antiseptic and immune stimulating properties.

    It did not cure the Schistosomiasis it only kept me from succumbing to the severe symptoms of infection. It brought the symptoms under control enough where I could function.


    DE (Diatomaceous Earth Food Grade): I found DE to be helpful and have seen some microscopic evidence of it shredding adult worms.


    Turmeric: An old spice from India has really helped me with the inflammation associated with Schistosomiasis. Along with that I ran across a article describing how it keeps the worms apart and prevents them from mating. This is true I did notice a drop in egg production and an ease of the bladder pain and relief from the urge to urinate.


    Fennel Oil: Again I found an article from Brazil from a university that did research and found the Fennel Oil killed schistosomiasis, not an effective as praziquantel but it was notable.


    Cedar Oil: Natural essential oil of cedar was mentioned from the article along with Fennel oil. The Cedar is a preventive oil that can be applied to the skin in hopes to avoid infection. Much like a sunblock or jellyfish sting preventive though I have only limited experience with it.


    Cranberry Mannose + Probiotics: A combination drink powder recommended for the treatment of urinary tract infections. Mannose is a simple sugar and with schistosomiasis like all parasites loving sugar it attracts them to it and they bind with it and your body passes them out. This led me to discover using the drink mix as a relief to schistosomiasis "flareups" or when the worms were dropping a high volume of eggs. It does not cure schistosomiasis but eases the burden and offers some relief.

  • Schistosomiasis (IC) Connection

    Interstitial Cystitis (IC)

    We partnered with an I.C. (Interstitial Cystitis) support group in the U.K. and tested them. Most of these ladies have been clinically diagnosed as having I.C. by their GP.


    The results were 21 people tested to include some of the ladies partners or spouses and there were 14 positives in the group with 7 negatives.


    Most of the ladies had symptoms equal to schistosomiasis with bladder pain and vaginal discomfort being the number one complaint. None of the ladies had any travel to endemic regions in the world where schistosomiasis was present. They all started to show symptoms after having sexual relations with men. Some of those men were from an endemic regions or have traveled themselves to an endemic region only to bring it back with them.


    The more I study this I am convinced that this is a new strain of schistosomiasis and is being spread sexually. As an infected male or female in that matter, is capable of hosting the parasite in their genitals allowing it to spread during intercourse. Simply put if a male had become infected with schistosomiasis haematobium and was shedding eggs at the time of sex he would ejaculate those eggs into the female's vagina. There it would be met with a hospitable environment, wet, warm and acceptable for it to hatch within its 15 minute window of exposure to water (vaginal fluid). Once it has hatched it's now a miracidia and free to move about looking for a blood supply to continue its lifecycle into an adult worm.


    A few of the ladies were able to receive praziquantel and took it in a varying number of ways. Some took it at 60mg/kg single dose, 60mg/kg divided over 3 doses in a day, one tried taking that dose for 3 days in a row.


    We know that praziquantel works to kill the adult worms but we are lacking an approved drug to treat the juvenile stage of the infection. Without this we are just kicking the can down the road so to speak as you will never become cured. The current drug administration usually is a second dose at 6 weeks as that is the time it takes to mature into an adult. There is an herbal remedy but it's just that an unregulated or approved to treat schistosomiasis and that is wormwood. Wormwood as been long used in history to treat parasitic infections in the larval stage. It is very close chemically to Artemether a pharmaceutical drug that is used to treat malaria.


    As a result of the study subjects that took praziquantel followed by herbal treatment were cured of Interstitial Cystitis / Schistosomiasis.

  • Sexually Transmitted Parasite

    Schistosomiasis as an STD

    Sexually Transmitted

    Female Genital Schistosomiasis:

    Because Haematobium resides in the urinary and reproductive tracts it can be spread sexually. Infections typically show up as an UTI and are misdiagnosed as such.


    Search: World Health Organization Female Genital Schistosomiasis for facts.


    Schistosomiasis can also affect males as well as females. Cases are coming in about people with no travel history to subtropical areas contracting the disease from sexual partners in first world countries.


    We are finding adult schistosomiasis worms in semen and vaginal samples in the U.K. and U.S.. Along with this we have taken urine samples and found miracidia from those same people. Miracidia are a juvenile form of schistosomiasis as it makes its way through the growth cycle.


    Symptoms of an STD schistosomiasis infection will begin to show up 48 hours to a week later with increased urination accompanied with discomfort or pain. A sense of urgency to urinate every 2 hours is an indications that the human body is trying to expel a foreign object from the urethra.


    Semen quality in Schistosoma haematobium infected men in Madagascar.

    Acta Trop. 2009 Jan;109(1):41-4. doi: 10.1016/j.actatropica.2008.09.010. Epub 2008 Sep 30.

    Author information Abstract 

    The seminal vesicles and the prostate are frequently affected by egg-induced inflammation in Schistosoma haematobium infected men. The objective of this study was to assess the semen quality in men with male genital schistosomiasis (MGS). The examination of the semen samples was performed in men aged 15 to 49 years living an S. haematobium endemic area in Madagascar prior to anti-schistosoma treatment with praziquantel and five months later. Men from the high endemic Sirama sugarcane plantation with positive egg excretion in the urine and circulating anodic antigen (CAA) present in serum (n=85) were compared to men (without egg excretion and no CAA) from the neighbouring low-endemic Mataipako village (n=57). The proportion of men with egg excretion in semen was significantly higher in Sirama than in Mataipako (53% versus 4%), whereas the median ejaculate volume was significantly lower in Sirama (1.8 ml versus 2.4 ml). There was no statistical difference in median spermatocyte counts and in the proportions of men detected with azoospermia. The mean apoptotic rate was 7.8% in a subgroup of 30 men from Sirama. A positive correlation was found between apoptotic rate and seminal eosinophil cationic protein (ECP) level (rho=0.560; P<0.001). At follow up, egg excretion and ECP level in semen declined significantly and were paralleled by a significant reduction in the apoptotic rate. The study suggests that S. haematobium infection is associated with sperm apoptosis and a reduced production of seminal fluid. Egg induced inflammation in the seminal vesicles and the prostate could be underlying mechanism for both observations.

  • Avian Schistosomiasis


    The bird schistosomes are a group of blood flukes (Platyhelminthes, Digenea). They contain the largest clade of the family Schistosomatidae that includes ten genera: Dendritobilharzia, Gigantobilharzia, Allobilharzia, Austrobilharzia, Anserobilharzia, Trichobilharzia, Bilharziella, Macrobilharzia, Ornithobilharzia and Jilinobilharzia. In the two-host life cycle (fresh water snails as intermediate hosts and aquatic birds as definitive hosts), they develop as adults with in venous and arterial vessels or nasal tissue of their bird host. Bird schistosomes of the genus Trichobilharzia are categorized as nasal and visceral groups depending on their target tissue within the final hosts (Horák et al., 2002; Brant et al., 2006). Cercariae of the bird schistosomes released from intermediate hosts are recognized as the great causative agent of human cercarial dermatitis (HCD) or Swimmer's itch which is considered an emerging disease in various parts of the World (de Gentile et al., 1996). Experiments have demonstrated that avian schistosomes can migrate and partly develop in other bodies of their non-specific mammalian hosts, causing serious health risks. Larvae of different visceral avian schistosome have been detected in the lungs of experimentally infected monkeys and rodents (Horák et al., 2002), and foot paralysis has been seen in mice infected with the neurotropic species Trichobilharzia regenti(Horák et al., 1999; Hrádková and Horák, 1999). Therefore, as a result of these experiments, It is thus considered conceivable that avian schistosomes may be responsible for some nervous or pulmonary symptoms in humans...

  • My Schistosomiasis Story

    In 2011 I became sick while working overseas in the Middle East with a fever, frequent urination along with kidney and bladder pain plus a long list of other health related problems due to parasites. I returned home gave the disease to my wife and we battled it together. It took me 6 years to finally figure out what was wrong with me as I was diagnosed with Schistosomiasis in 2017. We spent another 2 years trying to figure out how to cure her and remove it from her reproductive tract. I created a new drug to treat (FGS) Female Genital Schistosomiasis with a 1 dose cure rate. I am working to bring it to market as fast as possible for those who are suffering.  https://www.villya.net
