Answer

Arboviruses are an important cause of aseptic meningitis and encephalitis in the summer and fall months in the United States. West Nile virus was introduced to the United States in 1999 and has now spread throughout the continent. In 2012, the largest outbreak of West Nile virus infection to date occurred in the United States, with 5387 cases reported (about half of which were neuroinvasive disease, such as meningitis or encephalitis) and a 4.5% mortality. [12] West Nile virus can also cause acute flaccid paralysis, retinitis and nephropathy.
