Perfect storm: First wave of the COVID-19 pandemic crashes in Southeast San Francisco

Southeastern San Francisco and the 94124 zip code rank second highest in San Francisco in COVID-19 cases per 10,000 residents according to the Department of Public Health Mapping released on April 20, 2020.

New York Gov. Andrew Cuomo spoke at his daily briefing on April 23, 2020, and addressed, for the first time in the national dialogue, the perfect storm generated by the COVID-19 pandemic’s impact on dense low income, industrialized communities of color where cardiopulmonary diseases like asthma are exacerbated by exposure to the novel coronavirus along with air pollution and toxins from low paying service work in polluting industries.

On April 20, 2020, the San Francisco Department of Public Health released a map of confirmed cases of COVID-19 by zip code. That map corresponds to EPA mapping of city zip codes with the highest particulate matter emissions in tons per year.

SFDPH Map of COVID-19 cases in San Francisco documents a citywide rate of 14.23 cases per 10,000 residents. The 94124 zip code in Bayview Hunters Point ranks second highest with 27.89 cases per 10,000 residents – more than double the citywide rate! Note the mapping does not identify COVID-19 deaths by zip code.

Of note, over 20 tons of particulate emissions are generated in the 94124 zip code each year by construction dust, polluting industries and mobile sources. The 94124 zip code ranks second highest in COVID-19 cases per 10,000 population. 

An estimated 35,000 people live in the 94124 zip code. In interpreting the citywide COVID-19 case map, it is crucial to note that while the zip codes 94110 and 94112 report the highest number of cases, they represent wide geographic areas with populations double to triple that of 94124.

The most important information missing from the SFDPH COVID-19 case map are zip codes for the city’s 21 reported deaths.

Prepared statements issued by San Francisco Mayor London Breed include the grossly inaccurate misinformation: “I want to stress that when it comes to coronavirus, no zip code or neighborhood is inherently safer than another.”

This EPA map of particle pollution documents greater than 20 tons per year in the 94124 zip code. Note the overlay between maps of COVID-19 cases and particle pollution density in southeast San Francisco.

This is obviously not true! The San Francisco COVID-19 Response Map clearly identifies regions of the city’s westside with fewer than four cases reported. Indeed the 94132 zip code I reside in has NO reported cases and is not even included in the San Francisco mapping.

The pulmonary interstitium is part of the lungs’ anatomy. According to WebMD, the interstitium is a lace-like tissue spread throughout the lung that supports the air sacs and allows for gas exchange between the lungs and the blood stream.

The most important information missing from the SFDPH COVID-19 case map are zip codes for the city’s 21 reported deaths. Demographic breakdown of COVID-19 deaths by race, gender and age show 11 were Asian and the majority were male and over 60 years in age. The zip code distribution for San Francisco’s COVID-19 deaths is not documented.

When the delicate lace-like tissue called the interstitium becomes damaged and inflamed by COVID-19 and toxic air contaminants, it thickens, causing gas exchange in the lung to fail.

We know the 94124 zip code harbors inordinate incidences of cardiopulmonary diseases, diabetes and disabilities that increase the risk of contracting COVID-19. We know lung diseases caused by chronic exposure to airborne toxins look exactly like COVID -19 lung diseases and are called Interstitial Lung Disease (ILD).

A series of chest x rays reveal the characteristic ground glass appearance seen in interstitial lung disease. Damage to lung tissue called interstitium from either COVID-19 infection or exposure to air pollution leads to lung diseases, cough and difficulty breathing. The San Francisco Department of Public Health does not categorize interstitial lung disease as a separate and distinct form of cardiopulmonary disease.

Interstitial lung disease occurs in both COVID-19 infection and in people chronically exposed to air pollution. Little focus has been given to the fact that the disproportionate incidence of COVID-19 cases and deaths occurring in densely populated low income communities of color – like San Francisco’s Bayview Hunters Point 94124 zip code – are contributed to by the co-morbid risk of damage to the same regions of the lung by both toxic air contaminants and the novel coronavirus.

The interstitium is a lace-like tissue spread throughout the lungs that supports the air sacs and allows the gas exchange between the blood stream and the lungs. Interstitial lung disease is caused by thickening and scarring of the interstitium that interferes with oxygen exchange.

Peter Boraschi, MD, concludes COVID-19 pulmonary involvement is really an interstitial pneumonia and discusses imaging features of coronavirus disease 2019 finding “all patients showed ground glass opacity” on x-ray imaging. 

The Hunters Point Community Biomonitoring Program has detected toxic elements present in soils at the Hunters Point Naval Shipyard, its landfills and in the serpentinite bedrock of the Hunters Point hilltop where tons of asbestos and toxin containing particulates were generated by grading activities beginning in 2005.

A rare chart from the SFDPH 2004 Community Health Assessment documents top contributors to excess lives lost in 94124. Note violence is the leading cause of preventable loss of life followed by cardiopulmonary diseases linked to smoking and air pollution and cancers of lung, trachea and bronchi. The San Francisco Department of Public Health no longer tracks cancer by zip code. The 2019 Community Health Needs Assessment does not include cancer and cardiopulmonary diseases as a category for health needs. See

“In December 2019, a new type of coronavirus pneumonia (COVID-19) emerged in Wuhan and spread rapidly throughout China and to over 100 countries around the world. The lung injury and repair caused by COVID-19 has many similarities with the onset and progression of interstitial lung disease. See “Chinese researchers discuss challenges and management of COVID-19 in Interstitial Lung Disease.” 

Healthy lungs matter: The COVID-19 pandemic leads to death in those who develop diseases due to damage to the lung tissue called interstitial lung disease. In people exposed to toxic air contaminants, including particulates, asbestos, silica and volatilized compounds, chronic damage to the lung tissue causes interstitial lung disease.

In a March 2019 letter to Mayor London Breed, San Francisco Department of Public Health Director of Population Health Tomas Aragon, MD DrPH, documented a 31 percent increase in lung cancer in men residing in the 94124 zip code he attributed to cigarette smoking. There has been no corresponding increase in smoking in the 94124 zip code to warrant that conclusion. 

Indeed, the 2019 SFDPH Community Health Needs Assessment documents an 18 percent decline in tobacco retailers, a 10 percent decline in the number of packs of cigarettes sold in San Francisco and finds the 94124 zip code has an incidence of cigarette packs sold that is lower than many east and westside zip codes.

HP Biomonitoring … Detect … Protect … Prevent!

The Hunters Point Community Biomonitoring Program encourages all 35,492 residents of the high risk 94124 zip code to seek diagnostic and antibody testing for COVID-19 along with urinary screening for airborne toxins known to be present at the federal Superfund site and polluting industries. HP Biomonitoring is committed to offering expert clinical nutrition consultations and referrals for standard of care evaluation of symptoms due to interstitial and fibrotic lung disease caused by exposure to toxic, allergic and infectious agents.

Al Gore says climate crisis and coronavirus ‘linked’: Pollution makes preconditions worse

by Rebecca Klar, The Hill

Former Vice President Al Gore said Monday that the climate crisis and issues surrounding environmental injustice are linked with the coronavirus pandemic.

“This climate crisis and the COVID-19 pandemic are linked in some ways,” Gore said on MSNBC. “The preconditions that raise the death rate from COVID-19, a great many of them, are accentuated, made worse by the fossil fuel pollution.”

Emerging statistics have illustrated that the coronavirus pandemic has had a disproportionate impact on communities of color.

Gore said the crisis has “exposed some longstanding weaknesses” in the country.

For example, Gore noted the death rate, before the pandemic, among Black children from asthma was much worse than for white children with asthma.

According to the Department of Health and Human Services, in 2015 African American children with asthma had a death rate 10 times that of non-Hispanic white children, and Black children are four times more likely to be admitted to the hospital for asthma as compared to non-Hispanic white children.

Gore said environmental injustice is just one factor, in addition to inadequate access to health care and unequal economics, that leads to the disproportionate impact of COVID-19 and other health issues.

Communities of color have had “a legacy of being deprived of the same political and economic power to defend themselves” and they’re more likely to be in polluted areas, such as “downwind from the smokestacks” or “downstream from the hazardous waste flows,” Gore said.

“This is now being manifested in these horrendous death rates,” he said.

Gore also criticized President Trump‘s handling of the crisis.

“He ignored the science, as he has done with the climate crisis as well,” Gore said. “He has engaged in a kind of magical thinking. He’s pushed dangerous and potentially deadly snake oil-type remedies.”

Gore urged Americans to push aside partisanship when thinking about the November elections.

“I hope that a lot of people will put the country first and try, even in this time of extreme partisanship, to try and set that aside and look at what is at stake here,” Gore said. “I mean seriously, we are really in trouble with the kind of performance in the Oval Office we’ve had. We’ve got to change that. … I know that sounds partisan, but it’s more than that; it’s way more than that.”
