Final answer:
Signs not typically associated with arboviral encephalitis include flaccid paralysis, respiratory paralysis, and hydrophobia. Symptoms of arboviral encephalitis most often include fever, headaches, and restlessness, which can escalate to convulsions and coma in severe cases.
Step-by-step explanation:
Signs and symptoms that are not typically associated with arboviral encephalitis include flaccid paralysis and respiratory paralysis, which are more commonly seen in other neurological infections. Likewise, hydrophobia is a symptom specifically associated with rabies, another viral disease, rather than arboviral infections. As most arboviral infections result in either asymptomatic cases or symptoms like fever, chills, headaches, vomiting, diarrhea, restlessness, and in severe cases, convulsions and coma; any symptoms deviating significantly from these patterns, such as skin rashes or persistent cough, would not typically be signs of arboviral encephalitis.
