Concord: Ash/Debris Cleanup Advisory


Last updated: April 24, 2018, 9:41 am

The large structure fire in Concord consisted primarily of construction materials (predominately wood). Residents should avoid direct contact and inhalation of ash/debris that was produced by the fire. Residents may use a mild soap and water to clean up ash/debris. To minimize dust generation, residents should consider lightly dampening ash/debris prior to commencing sweeping activities. Swept up ash/debris may be placed in a standard household trash receptacle. Any towels or cleaning materials should be rinsed in a sink that drains to a sanitation sewer. Residents should avoid washing or sweeping ash/debris into storm drains, as this will result in pollution accumulating in nearby creeks and rivers.

West Nile Virus

Provider Information


A review of hospital discharge data from 2009-2010 found that 80% of patients with illness potentially compatible with neuro-invasive arboviral disease were not tested for WNV. While there is no specific treatment for WNV, testing can help differentiate WNV from other conditions, provide anticipatory guidance for patients as they experience potentially lingering symptoms, and help mosquito control and public health agencies institute proper control measures to prevent further cases.

Reporting Criteria

Report any suspect case of WNV within one working day of identification to Contra Costa Public Health Communicable Disease Programs by phone at 925-313-6740 or fax the West Nile Virus Case Report Form to 925-313-6465.

Laboratory Testing

WNV testing is available through Contra Costa Public Health Laboratory by completing the Laboratory Requisition Slip. Regarding specific information on WNV specimen submittal please refer to the posted health advisory. For additional assistance with submittal call Contra Costa Public Health Laboratory at 925-370-5775.

Remember to submit specimens with the West Nile Virus Infection Case Report Form.
