Rakhine, Myanmar: 828 suspected patients and 428 patients diagnosed with schistosomiasis

Schistosomiasis lifecycle

Eggs are eliminated with feces or urine The number 1 . Under optimal conditions the eggs hatch and release miracidia The number 2 , which swim and penetrate specific snail intermediate hosts The number 3 . The stages in the snail include 2 generations of sporocysts The number 4 and the production of cercariae The number 5 . Upon release from the snail, the infective cercariae swim, penetrate the skin of the human host The number 6 , and shed their forked tail, becoming schistosomulae The number 7 . The schistosomulae migrate through several tissues and stages to their residence in the veins ( The number 8 , The number 9 ). Adult worms in humans reside in the mesenteric venules in various locations, which at times seem to be specific for each species The number 10 . For instance, S. japonicum is more frequently found in the superior mesenteric veins draining the small intestine The letter A , and S. mansoni occurs more often in the superior mesenteric veins draining the large intestine The letter B . However, both species can occupy either location, and they are capable of moving between sites, so it is not possible to state unequivocally that one species only occurs in one location. S. haematobium most often occurs in the venous plexus of bladder The letter C , but it can also be found in the rectal venules. The females (size 7 to 20 mm; males slightly smaller) deposit eggs in the small venules of the portal and perivesical systems. The eggs are moved progressively toward the lumen of the intestine (S. mansoni and S. japonicum) and of the bladder and ureters (S. haematobium), and are eliminated with feces or urine, respectively The number 1 .

Pathology of S. mansoni and S. japonicum schistosomiasis includes: Katayama fever, hepatic perisinusoidal egg granulomas, Symmers’ pipe stem periportal fibrosis, portal hypertension, and occasional embolic egg granulomas in brain or spinal cord. Pathology of S. haematobium schistosomiasis includes: hematuria, scarring, calcification, squamous cell carcinoma, and occasional embolic egg granulomas in brain or spinal cord.

Human contact with water is thus necessary for infection by schistosomes. Various animals, such as dogs, cats, rodents, pigs, hourse and goats, serve as reservoirs for S. japonicum, and dogs for S. mekongi.

WSJ

“…..Defendants Wa Lone and Kyaw Soe Oo were entrapped by police officers who planted classified documents on them to disrupt their reporting into atrocities in Rakhine state, according to their defense. Myanmar has been accused by United Nations investigators of genocide in a crackdown launched a year ago against ethnic Rohingya Muslims that left about 10,000 people dead and forced more than 700,000 to relief camps in Bangladesh.  Messrs. Wa Lone and Kyaw Soe Oo shed light on abuses that included the massacre of 10 Rohingya men and boys in the village of Inn Din. Their photos of the victims, who were tied together before being executed, prompted a rare admission of wrongdoing by Myanmar’s military, which has otherwise rejected claims that it violated human rights in what it calls an antiterrorism campaign……”
