I have a medic friend in Iraq, near this area. According to him, they believe the Cholera is not being caused by the water treatment system, but because many don’t have access to this water.
They try to find their own water supplies, which are being contaminated by the large number of refugees. At least that is their theory so far. The epidemic is spreading because there are many who are malnourished and living under pretty awful conditions. He says they are busy, but fine so far, with plenty of tetracycline, and deliverable potable water. They are working 24/7 on locating the source of the problem, and educating the population on ways to avoid and treat infection.
Glad to hear the people are getting good treatment.
