Hi!
How are you?
You might have acquired a
parasitic infection known as
Schistosomiasis.
With a history of travel to DR and the problems getting soon after returning from that country are highly suggestive of Schistosomiasis.
Infection occurs through contact with contaminated water with the parasite in open bodies of water.
On contact with humans, the parasite burrows into the skin, matures into another stage then migrates to the lungs and
liver, where it matures into the adult form.
The adult worm then migrates to its preferred body part, depending on its species. These areas include the bladder,
rectum, intestines, liver, etc.
causing blood in the stools (which gets darkened), blood in the urine, etc.
This infection responds to the drug Praziquantal. Kindly consult your physician for the confirmation and further management.
Nothing to worry, it gets cured following a complete course of Praziquantal.
Take care.
Regards!
