If Zika is similar to dengue, then only some people get those symptoms. Other people just feel something like they have influenza without the sneezes and the runny nose.

Those diseases spread easily precisely because many people have it and don't stay home with mosquito net and repellents. They just go on with their lives, transmitting the disease to other people who may be more vulnerable and have worse symptoms.

It's a bit different, the symptoms regarding Zika are really strong, that's why people are certain it's Zika because you fall in bed really. So if I get through "transmission" I would get the same symptoms.. it's hard to understand but if you understand the different types of Dengue and their symptoms you will understand how Zika is different and it's not soft (like a cold or virus flu).

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.
