State of California
- COVID19.CA.GOV is the State of California’s official website that provides data, resources, volunteer opportunities, safety precautions, and tools for the response to COVID-19 in California.

COVID-19 Community Health Data, Indicators, and Tools
- California COVID Assessment Tool (CalCAT) is an interactive modeling tool to inform state and local response. CalCAT includes:
- Effective reproduction number (R-effective) which is the average number of people each infected person will pass the virus onto and represents the rate at which COVID-19 is spreading.
- Short-term forecasts that take into account the most recent trends in cases, hospitalizations, and deaths and apply statistical models to those data to generate anticipated trends in the coming two to four weeks.
- Long-term scenarios that estimate the effect of various non-pharmaceutical interventions (NPIs)
- COVID-19 HPI Resource Map on the California Healthy Places Index (HPI) interactive platform - developed by the Public Health Alliance of Southern California, this tool supports local assessment, response efforts, and informs equitable resource allocation, program planning, and service delivery. Explore community conditions linked to life expectancy with up-to-date measures of COVID-19, including county-level death rates by race/ethnicity (where available). HPI also includes separate decision support layers for CDPH’s Climate Change and Health Vulnerability Indicators (CCHVIs) for California.
- Tracking California’s Who is Most Vulnerable to COVID-19 webpage describes factors contributing to the unequal effect COVID-19 is having across California. Tracking California also provides a COVID-19 Data and Resources page that includes resources for accessing stable and safe housing, health care, water service, healthy and affordable foods, parks and green space, and more, in the context of the pandemic. Tracking California mobilizes data to identify and understand pollution and disease, helping Californians take action to create healthier communities.
- National Weather Service (NWS) Forecast Maps and NWS Graphical Forecasts provide daily forecasts, maps, data, and advisories to assist in planning for weather, air quality, and smoke-related hazards that could be exacerbated by the COVID-19 pandemic and various local conditions.
COVID-19, Wildfires, and Wildfire Smoke
The COVID-19 pandemic overlaps with the wildfire season in California. The populations most vulnerable to COVID-19 overlap with the populations most exposed to air pollution and its respiratory and cardiovascular effects on health. The populations may also overlap in terms of being more vulnerable to having adverse health impacts from wildfire smoke exposure (while not being more likely to be exposed to the smoke itself). Most actions that health experts recommend for protecting communities from wildfire smoke remain the same, but some special considerations need to be made during the pandemic. Information on wildfire, wildfire smoke, and COVID-19 can be found below:

COVID-19 and Extreme Heat
COVID-19, Extreme Heat, and Cooling Centers
As summer temperatures increase, extreme heat is a major public health concern in California and can lead to heat-related illness, including heat stroke and death. Cooling centers can protect health during heat events but can also potentially facilitate the transmission of COVID-19 among both staff and visitors (particularly older adults or people with underlying medical conditions).
Other COVID-19 and Extreme Heat Resources
- Heat and COVID-19 Information Series and other resources - produced by the Global Heat Health Information Network (GHHIN) to support governments and communities in preparing for hot weather while managing COVID-19. Resources include guidance regarding vulnerable populations, ozone and heat, health workers and heat stress, personal protective equipment and heat, and more.
- Webinar Recording: Health and Equity Impacts of Extreme Heat [VIDEO] - Arizona State University School of Sustainability hosted a discussion to address the disproportionate health impacts of extreme heat on communities already facing social and health inequities, and the need to manage multiple concurrent emergencies in the context of COVID-19.

COVID-19 Guidance for Environmental Health Practitioners
- CDC COVID-19 Guidance for Environmental Health Practitioners - developed by the Centers for Disease Control and Prevention (CDC), provides guidance around congregate facilities and shelters, cleaning and disinfection, food safety, water safety, solid waste and debris, natural disasters, wildfires, and air quality, and more.
