NASA Earth Observing System Data and Information System (EOSDIS) Worldview. San Mateo County, located about 200 miles downwind, experienced 7 days with concentrations exceeding “Unhealthy” AQI levels.įigure 1. 2Īs the smoke from the Camp Fire spread south, Sacramento County, located about 88 miles downwind, observed 24-hour maximum fine particulate matter (PM2.5) concentrations exceeding 260 μg/m3 (on day 8 of the 18-day event), with 11 consecutive days exceeding “Unhealthy” Air Quality Index (AQI) levels (24-hour average PM2.5 >65.5 μg/m3).
1 Today, more than 25 million acres of wildlands-a risk area of over half the state-are classified as a very high or extreme fire threat in California. In 2018, California experienced the most destructive wildfire season on record, with 7,571 fires burning nearly 1.7 million acres, over 23,300 damaged or destroyed structures, and 93 confirmed fatalities.1 The Camp Fire, which began on November 8, 2018, in east wind-driven fire-prone wildlands in Butte County, Northern California, was the deadliest wildfire in California history and sixth-deadliest U.S. Funding from the National Syndromic Surveillance Program supports the use of syndromic surveillance in improving the nation’s public health. The state’s experience demonstrated the utility, reliability, and timeliness of syndromic data for monitoring and characterizing wildfire-related health impacts. They set up monitoring and response plans and formed data-sharing relationships across jurisdictional lines.Ĭalifornia’s use of syndromic data during the 2018 wildfire season formed cross-jurisdictional relationships and a desire for regional collaboration and information exchange around emerging areas of syndromic surveillance. Epidemiologists in Sacramento and San Mateo counties quickly adapted the wildfire-related syndrome definitions and surveillance techniques.
NSSP scientists contacted Sacramento, San Mateo, and other affected sites to propose technical assistance, guidance, and resources for monitoring wildfire events. 2Īt the onset of the fires, California’s decentralized and independent public health jurisdictions were in various stages of becoming part of CDC’s National Syndromic Surveillance Program (NSSP). 1 More than 25 million acres of California wildlands are classified as very high or extreme fire threats-a risk area covering more than half the state. In 2018, California experienced its most destructive wildfire season on record.
