Claim 8: “The West Nile virus is the only mosquito borne disease known to spread to humans in New York City and has been plaguing Gothamites for over 25 years.”
MISLEADING
While West Nile virus has been present since 1999 (over 25 years), it is not the 'only' mosquito-borne disease. While it is the 'leading' cause, other arboviruses exist globally, and the evidence mentions it as an example of vector-borne diseases alongside Lyme (tick-borne), but doesn't explicitly support the claim that no other mosquito-borne diseases spread to humans in NYC.

web search NEUTRAL — Diseases that spread this way are called vector-borne diseases. Examples you may have heard of in NYC are West Nile virus disease, spread by mosquitoes, and Lyme disease, spread by ticks.
