The predominantly black and low-income communities living near the back-to-back petrochemical refineries of Louisiana’s “cancer alley” have long suffered compromised immune systems and high rates of disease. Now, the state’s fast-growing COVID-19 outbreak is poised to hit them especially hard.

Yet behind the veil of the pandemic, last week the Environmental Protection Agency (EPA) issued a temporary policy — with no end date specified — to suspend its enforcement of key environmental regulations, allowing industries like Louisiana’s petrochemical giants to make their own determinations as to whether or not they are complying with requirements to monitor pollution levels. Ironically, as the EPA relaxes its rules for polluters, the link between long-term exposure to environmental hazards and the most severe outcomes of coronavirus infections is starting to come into focus.

Jvion, a healthcare data firm, has collaborated with Microsoft to launch a new COVID-19 community vulnerability map to identify the populations most vulnerable to severe complications following a coronavirus outbreak. The interactive map aggregates socioeconomic and environmental factors, such as lack of access to transportation, exposure to toxins, unemployment, and mortality rate. According to the map, these factors make certain “cancer alley” communities particularly vulnerable.
