Why it matters

Add The New York Post on Google A New Yorker has contracted the potentially dangerous West Nile virus — the first reported human case in the city this year, health officials revealed Wednesday.

Common ground

The unidentified city dweller fell ill with the mosquito-borne disease after spending time outdoors around the city, and in several locations outside the Big Apple, health department officials said.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
