The most commonly observed neurological syndromes in WNV positive patients were meningitis (16/29, 55.17%, 95.00% CI (35.69–73.55)), AFP (6/29, 20.69%, 95.00% CI (7.99–39.72)), seizures (3/29, 10.34%, 95.00% CI (2.19–27.35)) and encephalitis (1/29, 3.45%, 95.00% CI (0.09–17.76)), but the development of these syndromes was not statistically associated with infection (p ≥ 0.05). The gene discussed is AFP; the disease is encephalitis.
