Delaware Public Health to spray after La Crosse virus case; city notifies residents of one‑mile treatment radius

The Delaware Public Health District plans to fog a roughly one‑mile radius in Sunbury after detecting a human case of La Crosse virus, City Administrator Chris Hennessy told council. "Earlier today, the Delaware Public Health District notified us that they're going to, spray for mosquitoes in the city this evening. There has been a human case of a LaCrosse virus, detected here in the city," Hennessy said, and he pointed council members to a map in the packet showing the center point near SR 3 and Cherry with an approximate one‑mile radius. Hennessy said the public health district also deployed a mobile office to the square to assist residents and can test mosquitoes from individual properties on request. Officials said the city will share maps and timing details once dates are confirmed and encouraged residents with concerns to contact the Delaware Public Health District. No council action was required; the announcement was an informational update to the public safety portion of the administrator's report.
