&gt; &quot;Fever by Zika virus is described as an acute febrile illness.&quot;<p>&gt; There you go! See that there&#x27;s a difference from the other statement?<p>I think you are confused about medical terminology, particularly, I think you are confusing <i>acute</i> fever (which is a fever with sudden onset) with <i>severe</i> fever.<p>&gt; I have never seen a case till today regarding this, neither has the society here a person that had Zika but very little symptoms, it&#x27;s always hard and pushes the people to bed<p>I&#x27;m pretty sure that the reason these sources have stated this is that people with Zika but very few symptoms <i>have</i> been identified by medical authorities. OTOH, many people with Zika but without severe symptoms won&#x27;t ever know they had Zika, since they may not seek medical attention.
