Since returning from Senegal, my health has been relatively stable. I may still have amoebas (sort of like parasites living in my gut), but they were pretty much a part of my body for the past two years. The other day, however, I got a letter from Peace Corps Headquarters that I may have an early stage infection of Schistosomiasis. "Schisto" as it is known around the ex-pat community, is a nasty little parasite that burrows into our bodies from snail-born flatworms living in fresh water. Although the PC letter said that at this time I only need a second test to further determine if I am infected or not, I am, to put it mildly, freaked out. I am also freaked out by the fact that any of my treatment will have to come through worker's compensation, and I am now living outside of that comfortable bubble of PC medical care.
According to the CDC, over 200 million people throughout the world are living with a Schistosomiasis infection, which makes me wonder, what do they all do for treatment? Wikipedia has a lot of information on Schistosomiasis, but not much on treatment. Last December, our PC doctors informed us that the CDC found the regular treatment was becoming less effective, but I am not sure whether that includes early-stage infections or not.
The Schisto Life Cycle According to the CDC:
Infection occurs when your skin comes in contact with contaminated fresh water in which certain types of snails that carry schistosomes are living.
Fresh water becomes contaminated by Schistosoma eggs when infected people urinate or defecate in the water. The eggs hatch, and if certain types of snails are present in the water, the parasites grow and develop inside the snails. The parasite leaves the snail and enters the water where it can survive for about 48 hours. Schistosoma parasites can penetrate the skin of persons who are wading, swimming, bathing, or washing in contaminated water. Within several weeks, worms grow inside the blood vessels of the body and produce eggs. Some of these eggs travel to the bladder or intestines and are passed into the urine or stool.
I was very careful to avoid swimming in lakes and stagnant water, even when I was very hot, and being in water would have been a great relief. However, a lot of my work entailed standing in wet fields, and wading to collect water for plantings. Contact with fresh water was unavoidable in my line of work, and schisto will continue to be a threat to Ag workers in developing countries.
It's a little unnerving, not knowing for sure whether I have the infection or not. I have a doctor's appointment for this afternoon, but the test results may not be in for several weeks. Until then, I will just have to wait and see if I have worms and worm eggs in my body - in addition to the amoebas already there.
UPDATE:
Yesterday I went to the doctor and got my blood test. He surmises that it will be a month before I receive the results, so until then, I just sit and wait - and hope that I don't become symptomatic, because I would be in a grey area of coverage. FECA (The Federal worker's comp) won't cover anything until they have a confirmed blood test. On a happier note, I did not just infect half of Lake Don Pedro; apparently the lake is large enough so that I did not just create a public health emergency while I was up there last weekend.
