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.
  

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:

• Centers for Disease Control and Prevention (CDC) Guidance

• Wildfire Smoke and COVID-19 - CDC guidance and information on how wildfire smoke can affect you and your loved ones during the pandemic and what you can do to protect yourselves.
• Public Health Strategies to Reduce Exposure to Wildfire Smoke during the COVID-19 Pandemic - information about wildfire preparedness and response during the ongoing COVID-19 pandemic. It should be used in conjunction with the 2019 revision of Wildfire Smoke: A Guide for Public Health Officials.

Areas of smoke are analyzed and added daily during daylight hours, as visible satellite imagery becomes available.
  
  
• British Columbia Center for Disease Control (BCCDC) Guidance for Wildfire Smoke and COVID-19 [PDF] provides guidance for how to stay healthy in smoky conditions in the context of COVID-19. 
  

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).

• CDPH Guidance for Cooling Centers on COVID-19 - provides guidance to support a safe, clean environment for members of the public and workers at cooling centers.
  
  
• CDC COVID-19 and Cooling Centers - interim guidance to reduce the risk of introducing and transmitting COVID-19 in cooling centers. It should be used in conjunction with existing cooling center guidance.
  
  

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.
  

• CDC COVID-19 Guidance for Natural Disasters and Severe Weather - developed by the Centers for Disease Control and Prevention (CDC), provides information on how the COVID-19 pandemic can affect disaster preparedness and recovery, and what you can do to keep yourself and others safe.
  

• CDC Environmental Health Assessment Tool for Disaster Shelters - tool assists environmental health practitioners in conducting a rapid assessment of shelter conditions during emergencies and disasters. This tool can be modified to meet local needs during the COVID-19 emergency.
  
  

• CDC COVID-19 and General Population Disaster Shelters [PDF] - provides interim guidance on reducing the risk of introducing and transmitting COVID-19 in general population disaster shelters before, during, or after a disaster.
