Isn't the only way to say you have Zika to test specifically for that virus in your blood !?
I mean, just because you are tired a bit and have fever and a few other symptoms surely can't be enough, it could be a lot of other things...
When you have been here a while and see enough people with enough symptoms, there is no need to go to a usually pretty incompetent doctor who will no make any diagnosis without an expensive blood plus poo and pee test to tell you what you already knew. Plus there is no treatment. Zika, Chikungunya and Dengue are all different and the latter is the one to watch out for especially if you have had it at least once before. Zika is low grade fever, conjunctivitis and bright red eyes, full body rash, aching joints and feeling tired. Dengue has a much higher fever and Chikungunya has no conjunctivitis but joints are more painful and lasts for longer. The only reason you need a diagnosis for something by means of a blood test is to help the government with their figures or to receive the correct treatment and given there is no treatment for Zika then a waste of time and money for a couple of days discomfort.
