Most of the time people are not in fact certain that it's zika. That's why the number of confirmed cases is so low relative to the number of suspected cases. When you get common viral infection symptoms, it's common in Paraguay to avoid Aspirin just in case it's dengue, even if you don't have the joint pain and spots in the skin that the disease is known for. Some considerate people even use mosquito repellent when they get suspicious, so they won't transmit the disease in case it really is dengue.
