The diseases which attacked them were in the form of dysenteries, tenesmus, lientery, and fluxes; but, in some cases, there were dropsies, with or without these complaints.
In the first place, tenesmus, accompanied with pain, attacked many, but more especially children, and all who had not attained to puberty; and the most of these died.
Herophon was seized with an acute fever; alvine discharges at first were scanty, and attended with tenesmus; but afterwards they were passed of a thin, bilious character, and frequent; there was no sleep; urine black, and thin.
Samuel may not have noted tenesmus because there was nothing to report.
In some men, this brought vomiting, but the most common reactions were waves of painful peristalsis in the gut, accompanied by tenesmus, a desire, but inability, to use the bathroom.
This is followed almost immediately by various symptoms; more rapid breathing, lowered arterial pressure, faster heart-beat, vomiting, blood diarrhoea and rectal tenesmus.
"Severe vomiting, diarrhoea, rectal tenesmus: unable to keep standing, she urinates under herself; the pupils are dilated, the eyes haggard; complete mind-blindness, near-total failure of reflexes, deep unconsciousness, breathing dyspneic, heart-beat faint and very fast, pulse barely perceptible; dead in thirty-six hours."
Purging not always present, but tenesmus and strangury.
Acrid, metallic taste, constriction and burning in throat and stomach, nausea, vomiting of stringy mucus tinged with blood, tenesmus, purging.
_ -- Burning pain and constriction in throat and gullet, pain and tenderness of stomach and bowels, intense thirst, nausea, vomiting, purging and tenesmus, with bloody stools, dysuria, cold skin, and feeble and irregular pulse.
