In a follow up to a story 10 days ago, American Samoa health authorities are reporting an increase in amoebic dysentery cases while the source of the outbreak is still a mystery.
According to a Radio New Zealand report today, the number of cases have shot up to 165, with more than a dozen requiring hospitalization.
Epidemiologist Mark Durand notes that 56 of the cases have been confirmed as Entamoeba histolytica, a protozoan parasitic cause of dysentery, while cases of Shigella have also been reported. Shigella is the cause of bacillary dysentery.
Durand says they have yet to pinpoint a common source saying, “It doesn’t a particular store, a particular eating place, a particular event, a particular part of the island, a school, a workplace, a food source that seems like it is the unifying factor behind all of these cases.”
