SEIJO, Alfredo et al. Outbreack of St. Luis encephalitis in the Metropolitan Buenos Aires Area. Medicina (B. Aires) [online]. 2011, vol.71, n.3, pp. 211-217. ISSN 0025-7680.

We describe the epidemiological and clinical findings of 13 patients with diagnosis of infection by St. Louis encephalitis virus, transmitted between January and March 2010 in Buenos Aires Metropolitan Area (AMBA). Thirteen patients, average age 38 years, had an acute onset with hyperthermia and headache. Between days two and ten of the onset of symptoms, 7/13 patients had signs and symptoms of neurological involvement. This was characterized by meningitis without encephalic sings in 1/7 and in 6/7 the most frequent findings were: stiff neck, disorientation, photophobia, confusion and language impairment. Two MR and one EEG revealed signs of involvement of temporal lobes. The cerebrospinal fluid showed pleocytosis with predominance of mononuclear cells, normal glucose and moderately elevated protein. There were no fatalities cases. In 6/13 patients the initial clinical suspicion was dengue. As epidemic virus circulation had not been previously reported in the AMBA it can be considered an outbreak of St. Luis encephalitis for the spatial and temporal clustering of cases.
