Polio virus in Israel's water supply. Is this an act of terrorism?

Israel's last polio case was reported in 1988, and the WHO declared the country polio-free in 1992.

It's not an act of terrorism ... virus source is sewage from Palestinian towns in the West Bank that flows into the environment untreated.

On 3 June 2013, the World Health Organization (WHO) reported:

“In Israel, wild poliovirus type 1 (WPV1) was isolated from sewage samples collected on 9 April 2013 in Rahat, southern Israel. . . . Genetic sequencing and epidemiological investigations are ongoing to determine its origin. Preliminary analyses indicate the strain is not related to the virus currently affecting the Horn of Africa.”

On 3 July 2013, Israel's newspaper Haaretz reported:

"Almost 90 percent of sewage from Palestinian towns in the West Bank flows into the environment untreated, contaminating the groundwater and 162 kilometers of streams, according to a report prepared by the Israel Parks and Nature Authority.

"The report, prepared for the Environmental Protection Ministry and the Civil Administration in the West Bank, is based on water samples taken from various locales in 2012. It found that some 50 million cubic meters of sewage flow into the environment from Palestinian towns every year. Only 5 million cubic meters go to treatment plants, some of which are substandard. This affects Israel as well as the West Bank, since the polluted streams flow into Israel.. .

It doesn't occur every once in a while, but I don't think it's terrorism.

I read today it started from a dog that bit a solider in the Golan Heights.

I don't know if it is true but that is what I read.

No, it was brought from Africa by sick immigrants with poor hygiene and no master plan.
