Washington state is facing an unprecedented public health challenge with the epidemic of the novel coronavirus and Covid 19, the disease associated with the virus.

The Centers for Disease Control and Prevention (CDC) confirms that some populations are particularly vulnerable to the novel coronavirus and are more likely to develop serious illness and complications from Covid 19, the disease associated with the novel coronavirus.

Specifically, older adults and people who have serious chronic medical conditions, including heart disease, diabetes, and chronic lung disease. In addition, the high degree of transmissibility of the virus means that people living in areas of higher population density may also be at elevated risk.

To better understand how communities in Washington state may differ in their vulnerability to Covid 19, we developed a data visualization that combines key risk factors, using data from the US Census together with data from the Washington Department of Health. We created a census tract (CT)-level index that represents the population vulnerability to Covid 19 as follows. For each census tract in the state (n=1446), we generated an index that combines an indicator of disease burden from diabetes, lung disease, and heart disease in people 65 years and older using mortality data. We also accounted for population density. The disease burden was weighted at 0.75 and the population density was weighted at 0.25. All census tracts with populations older than 65 of less than 20 individuals were not analyzed.
