Premise: "Unlike the three subtypes, Zaire, Sudan and Ivory Coast, which can cause hemorrhagic symptoms, Reston does not. There has been no evidence that Reston can cause significant illness in humans. When Reston was previously found in monkeys, few animal handlers were infected but only one had very mild symptoms," the DOH's official website announced. In January 1997, the Philippines Department of Environment and Natural Resources ordered the immediate slaughter of some 600 monkeys in Ferlite, a breeding farm in Laguna, to prevent an outbreak of Reston ebolavirus.
Hypothesis: Macaques cause agricultural hardships.
