Where Are The Newest COVID Hot Spots? Mostly Places With Low Vaccination Rates

Health News from NPR, Updated July 9, 20212:05 PM ET
Heard on Morning Edition

As the weather warmed up this year, coronavirus case numbers plummeted, and life in the U.S. started to feel almost normal. But in recent weeks, that progress has stalled.

The vaccination campaign has slowed, and the delta variant is spreading rapidly. And new infections, which had started to plateau about a month ago, are going up slightly nationally.

New, localized hot spots are emerging, especially in stretches of the South, the Midwest and the West. And, according to an analysis NPR conducted with Johns Hopkins University, those surges are likely driven by pockets of dangerously low vaccination rates.

“I think we should brace ourselves to see case increases, particularly in unvaccinated populations,” says Jennifer Nuzzo, a senior scholar at the Johns Hopkins Center for Health Security.

Cases are rising in many states

The number of people catching the virus has risen in more than half of the states over the past two weeks. And 18 states have greater numbers of new infections now compared with four weeks ago, including Arkansas, Florida, Iowa, Missouri and Oklahoma, where new daily cases have doubled.

“It’s an early trend,” Nuzzo says. “Unfortunately looking at what’s happening in individual states, I do worry we will continue to see national numbers increase.”

The number of people getting hospitalized for COVID-19 has also started rising again in nine states, according to Johns Hopkins: Arkansas, Florida, Hawaii, Iowa, Missouri, Nebraska, Texas, Wisconsin and Mississippi.

“I expect that more states would join that list in a few weeks as they continue to see case increases,” Nuzzo cautions.

Localized outbreaks at the county level

To understand what’s driving the small rise in cases at the state and national level, researchers are keeping an eye on county-level trends.

A federal team including the Centers for Disease Control and Prevention does a daily ranking of counties’ level of COVID-19 risk and identifies those it considers hot spots. These are places where COVID-19 presents a “high burden” to the community, measured in part by a significant rise in cases as well as increases in case positivity rates.

NPR and Johns Hopkins analyzed the current hot spots from the week of July 1 to July 7 to see how many of them have been in bad shape over a longer period. The analysis found that the vast majority of the CDC’s hot spot counties from the last seven days have seen increases in new cases compared with one month ago — 104 out of the 136 counties.

This shows that for many of these hot spot counties, the rise in cases “isn’t a blip,” Nuzzo says. “That means that they’re headed in the wrong direction” in those places.

Many of the places with dramatic rises in cases are rural areas or small towns.

For example, Newton County, Mo., has seen a 182% increase in new infections; Nacogdoches County, Texas, has seen a 632% increase. Ottawa County, Okla., has seen infections soar 828%.

Nuzzo points out that for some of the rural hot spots, the increases may be small in terms of total numbers, but that these communities typically have fewer health care resources to treat even a slight rise in COVID-19 cases.

“The ability to save lives is dependent on there being enough resources to offer lifesaving medical care,” she notes. “We could see people die from their infection that otherwise could have been saved.”

NPR analyzed counties included in a federal COVID-19 hospitalization dataset and found that COVID-19 hospital admissions rose modestly in one-quarter of these counties last week compared with two weeks ago. Nearly half of the places where hospitalization increased were in Southern states, with Texas, North Carolina and Georgia leading. Another quarter of counties that increased were in the Midwest.

Nuzzo says she’s worried about a continued trend of “localized surges” around the country.

“Most of the [hot spot] counties are in states that are also reporting state-level increases, but not all are. In fact, we are seeing counties in states that we haven’t really been worrying about — California and Washington state, for instance,” Nuzzo says.

Some of the hot spot counties are also in suburban and even urban areas. For instance, Salt Lake City has had new infections rise over the last month, as has Clark County, Nev., home to Las Vegas, and Contra Costa County, Calif., home to some San Francisco Bay Area suburbs.

The link with low vaccination rates

NPR’s analysis with Johns Hopkins illustrates dramatically the impact of vaccination rates on risk for localized outbreaks. Most — 9 in 10 — of the CDC hot spot counties that have seen increasing cases over the last month had lower vaccination rates than the average U.S. county.

Nationally, 47.6% of the U.S. population was fully vaccinated as of July 7. Rates in many of the hot spot counties with sustained outbreaks were drastically lower. For instance, Ottawa County in Oklahoma has only vaccinated about 24% of its population. Utah County, Utah, the second-most populous in the state, has about a 32% vaccination rate. The lowest rate in the list of hot spots was Newton County, Mo., at nearly 17%.

While urban and suburban counties tend to have higher vaccination rates than rural ones overall, NPR’s analysis found that hot spot counties, even in more urban areas, tend to have lagging vaccination rates. And across all geographic types, hot spot counties had lower vaccination rates. For instance, among all U.S. counties designated as “small urban” areas, the average vaccination rate was 41% nationally, whereas among the hot spots, it was 33%.

Researchers had long feared places with low vaccination rates would end up being at risk for outbreaks, says Dr. David Rubin, director of PolicyLab at Children’s Hospital of Philadelphia, which has been tracking the pandemic in the United States. And now that pattern is proving true, he says.

You can see this play out vividly in the different parts of Missouri, he notes. For example, St. Louis County in the metro St. Louis area has a vaccination rate of 47% of the total population and is seeing a small increase in new infections of 17% over the last 30 days. In Greene County, home to Springfield, Mo., the vaccination rate is more than 10 points lower and has seen a 275% increase in new cases.

“The emergence of the delta variant is going to mean for those areas with low rates of vaccination that they’re very much at risk to see significant increases in transmission, with potentially even exponential growth,” he says.

Some regions may fall prey to a scattering of new outbreaks, while others may stay relatively unscathed, Rubin says. For instance, he points to New York and Massachusetts, which have high vaccination rates, and so far, few new infections. “It’s like a wall has formed in the upper Northeast with regards to transmission,” he says.

But, as Nuzzo notes, localized flare-ups in unvaccinated areas could spread regionally.

“One of the things that we keep forgetting about this pandemic is that something that happens in one state is not isolated from something that will happen in another state,” Nuzzo says. “So as long as we keep seeing case increases in any part of the country, it remains a national crisis.”

A fall surge is predicted

The troubling rises in cases and hospitalizations are stirring worries that the country may be on the cusp of yet another national surge that could continue into the fall.

Ali Mokdad, a researcher with the University of Washington’s Institute for Health Metrics and Evaluation, says the delta variant is a “game changer” for the group’s forecasting models.

“The delta variant has changed all our projections,” he says. “It’s more likely to be transmitted, makes the vaccines less effective; previous infections are not protective. We will see a rise in cases.”

And that rise is likely to occur in the summer instead of the fall, as the group had previously projected. That’s in line with forecasts from a group of modelers organized by the CDC.

Deaths could start going up again too, by mid-August, Mokdad says. The Institute for Health Metrics and Evaluation projects that deaths could rise from their current rate of around 200 a day to up over 1,000 by fall.

And the burden of the pandemic, Mokdad predicts, will not be evenly shared.

“We’re going to see a divide in the country,” he says. Places that have high vaccination rates may still see small surges, he says, but “it will be much worse in these locations with low vaccination coverage.”

Things may worsen in the fall, in part because that’s when more people will be heading indoors as a result of cold weather.

No one is predicting things will get anywhere close to as bad as last winter. But researchers emphasize that any increase in deaths is a travesty, given that COVID-19 has essentially become a preventable disease.

Mokdad notes that among recent COVID-19 deaths, “the majority, 97[%] to 99% of the deaths, are among people who are not vaccinated.”

“It’s so sad for me on a daily basis to look at the number of deaths in the United States, knowing that these mortalities could have been prevented. No one — no one — should die from COVID19 while we have an effective vaccine.”

Researchers are hoping these early hot spots will be a wake-up call to communities with lower vaccination rates.

“They should be heeding the warning that’s coming out of Missouri and Arkansas and recognizing that they need to boost their vaccination rates,” says Rubin of PolicyLab at Children’s Hospital of Philadelphia.

Nuzzo agrees. “There’s a lot more that we can do to stop the spread of this virus and to prevent people from being hospitalized or dying from it,” she says.

Methodology

To categorize hot spots, NPR analyzed daily updates of all counties’ rankings on the Area of Concern Continuum from July 1 to July 7, provided by the Centers for Disease Control and Prevention. Sustained hot spots and hot spots were marked as such if they achieved that ranking at least once through the week.

Among these hot spots, Johns Hopkins compared 30-day averages of new COVID-19 cases to see where cases have seen sustained increases this month compared with the previous month.

Vaccination data comes from county-level counts of fully vaccinated people as of July 7 provided by the CDC and the Texas Department of State Health Services. NPR excluded Georgia, Vermont, Virginia and West Virginia, because fewer than 80% of their vaccination records included a person’s county of residence. NPR used the National Center for Health Statistics 2013 Urban-Rural Classification Scheme to calculate average vaccination rates by county type, weighted by county population, both for all counties and for the hot spot counties.

NPR calculated per-capita county hospitalization rates using seven-day counts of confirmed COVID-19 hospital admissions for the weeks ending June 26 and July 3. This data is provided in Community Profile Reports published by the White House COVID-19 team.

In Martinez, Contra Costa and elsewhere – white backlash to Black Lives Matter

White backlash to Black Lives Matter was swift. It was also expected

The expected hostility toward the racial uprising energizing the country has begun.

It was expected by behaviorists and historians because history reveals that when some white people feel threatened by social justice movements, they lash out.

On July 4, the paint had barely dried on the 165-foot long Black Lives Matter mural on the street in front of the Wakefield Taylor Courthouse in Martinez when a man and a woman showed up. They dumped black paint on the yellow letters.

“This is not happening in my town,” the woman said as she spread the paint with a roller.

The hateful display of counterfeit patriotism was video-recorded by bystanders and went viral. On Tuesday, Contra Costa County District Attorney Diana Becton charged Nicole Anderson and David Nelson with a hate crime for defacing the mural.

“It was a peaceful mural, and it was a powerful way, as we’ve seen all over the country, that has been used to think about the importance of Black lives,” Becton told me. “But this one in particular was to think about the importance of Black lives in Contra Costa County.”

The county is roughly 43% white, according to census data. Black people make up less than 10% of the county’s population, while Latinos account for about 26% of county residents.

A 2018 report by UC Berkeley’s Urban Displacement Project and the California Housing Partnership studied housing prices and demographic changes in the county from 2000 to 2015 to, among other things, understand trends producing “patterns of segregation and unequal access to high-resource neighborhoods that have defined the county’s racial and economic geography for decades.”

By 2015, the report concluded, “approximately half of low-income Black and Latinx households in the county lived in segregated, high-poverty tracts — approximately triple the rate of low-income Asian and White households, and a steep increase from 2000. Families in these types of neighborhoods typically face greater barriers to economic mobility [and] are more likely to suffer adverse health outcomes.”

Once again, systemic racism impacts the health, economic and educational outcomes of people of color.

The permitted Black Lives Matter mural in Martinez was repainted almost immediately, but get this: The very next day, a man was arrested for allegedly pulling a gun on people looking at the mural, according to the Police Department.

The retaliation is driven by hate, resentment and fear. Don’t be surprised if it lasts beyond next year’s presidential inauguration.

“These are old means of subordination that white people have used,” said UC Berkeley psychology Professor Dacher Keltner, referring to recent viral incidents, including in Indiana where a Black man was attacked in the woods by white men. “This racism is the fabric of this culture.”

And when protesters rallied earlier this week to support Vauhxx Booker, the Black man who called the Indiana incident an “attempted lynching,” someone drove their car through the crowd, NBC News reported.

Wait, there’s more. A white woman used the N-word while arguing with a Black woman in a Sacramento-area convenience store on June 25. A white diner called someone enjoying a family celebration at a Carmel Valley restaurant an “Asian piece of s—.”

“Trump’s gonna f— you,” he said, rising from the table.

He already has.

The president is a grifter who knows hate is currency in America. He stokes white fear and resentment by painting Black Lives Matter protesters as terrorists and thugs. On July 1, he called Black Lives Matter murals symbols of hate. If his lies were your main source of information about people of color, you’d think the white, Black, Latino, Asian and Indigenous people marching for social justice were a bigger threat to this country than the coronavirus.

That’s why a white couple in St. Louis pointed their guns at protesters who marched past their home.

“The narrative of police brutality, the narrative of oppression, the narrative of racism — it’s a lie,” said the man in the Martinez incident, identified as Nelson, who wore a red T-shirt with “four more years” on the front. “Why don’t you guys learn about history?”

Once again, ignorance is a hallmark of white supremacy.

Here’s a brief lesson in American history: Southern white people went to war and sacrificed a generation to preserve the right to buy, sell and trade Black bodies. Then this country built statues to honor human traffickers and to remind Black people that their place — no, our lives — were conditional. After slavery was abolished, the lynchings of Black people became appointment viewing. Black people’s homes, churches and offices were bombed during the civil rights movement.

I could go on, but you get the historical context. In this country, when some white people feel their way of life — their status — is threatened, they respond with violence.

Dana Frank, a research professor of history at UC Santa Cruz, told me that some white resentment turns into anger instead of reflection.

“There’s white people that are well-meaning or confused and clueless, and then there’s the people who are actively crossing over into hostility. The second category is much harder to reach,” she said. “I think it’s very hard for your average white person to see all those forms of institutionalized racism in which they come out ahead. How do you open the door to somebody seeing that without that person feeling threatened?”

By getting white people to talk to white people about systemic racism.

Justin Gomez, who obtained the permit for the street mural, organized the effort a week after flyers calling for white unity were distributed in Martinez. Gomez, who is Filipino and was raised in Walnut Creek, has two children. He’s a stay-at-home dad, and his wife is a health care worker.

He told me he was blown away at how quickly the mural was defaced. Then again, he lives in Contra Costa County.

“We see Confederate flags,” Gomez said. “We see a lot of racist rhetoric in our local social media circles, so we fully knew that that was going to happen and we were ready for it.”

Six gallons of yellow paint were delivered to him Monday.

“We’re ready to fix it again,” he said.

At least 14 dead in COVID-19 outbreak at Concord nursing facility

The outbreak is among the largest in the East Bay

East Bay Times, By Annie Sciacca, UPDATED June 24, 2020

CONCORD — At least 14 people are dead after COVID-19 infected 75 people at an East Bay skilled nursing facility, according to data published by the state.

The state Department of Public Health’s latest report shows that 14 patients at San Miguel Villa, a post-acute nursing facility in Concord, have died after contracting the virus, which infected 62 residents and 13 workers at the facility.

A call to the facility was not immediately returned, so it’s unclear when the deaths occurred. Data reported to the state by the nursing home within the past 24 hours reveal that there are still 45 patients there infected with COVID-19

The state list on Tuesday showed that at least one healthcare worker at the facility had also died of COVID-19, but a spokesman for the facility, Dan Kramer, said Wednesday that it had been incorrectly reported, and that no workers had died.

The latest outbreak is yet another example of how the disease has ravaged the Bay Area’s most vulnerable population of elders living in congregate settings such as skilled nursing facilities or assisted living centers.

Of the 94% of the state’s 1,223 skilled nursing facilties that reported COVID-19 cases this week, there are currently 2,300 patients and 49 health care workers with confirmed COVID-19 infections, according to the state data. Cumulatively, there have been at least 12,282 confirmed cases across California and 7,655 cases among workers at skilled nursing facilities. And 2,299 patients and 89 health care workers have died from causes related to the deadly virus.

In non-medical residential care facilities — known commonly as assisted living facilities — there have been at least 2,969 confirmed COVID-19 cases among patients and staff, who often provide assistance in feeding, bathing, taking medication and other activities. At least 398 people in those facilities have died from COVID-19.

In Contra Costa County, health services director Anna Roth told the Board of Supervisors during its Tuesday meeting that of the 18 COVID-19 deaths that occurred the past week, 16 were from long-term care facilities, such as nursing homes. She did not identify the facilities.

Dr. Sara Levin, a deputy health officer for the county, told the supervisors a county task force had been set up to visit care facilities and help them proactively beef up infection control protocols and provide support in acquiring masks, gloves and other protective equipment, as well as ensuring they had enough staff if workers had fallen ill. The county at the end of May issued a health order to conduct mass testing as a baseline for all long-term care facilities, and then to continue testing staff monthly.

“Where we’ve seen a lot of the spread is when staff in these low-wage jobs are having to work in multiple facilities to ensure their financial stability, without benefits that don’t necessarily allow them to have sick leave,” Levin said. When federal, state and county mandates prevented most visitors, she said, “many residents were staying in facilities, so it was staff members going out to the community … and bringing it in.”

Concord’s San Miguel Villa is a 190-bed nursing facility on San Miguel Road owned and operated by Mark Callaway, Gary Jarvis and Velda Pierce. Pierce and Callaway also own other Contra Costa nursing facilities: Alhambra Convalescent Hospital, Lone Tree Convalescent and Antioch Convalescent Hospital, according to state records.

Since 2017, the facility has had a total of 106 complaints or reported incidents, and state inspectors found a total of 36 “deficiencies.” Some of those deficiencies included problems with infection control.

In an inspection in April 2019, for instance, state inspectors found multiple licensed vocational nurse staff members had not followed proper handwashing protocols.

Last year, the family of an elderly man who died at San Miguel Villa sued the facility, saying its lack of staffing and training led to the man’s suffering. The facility used drugs to sedate him, the lawsuit alleged.

Staffing shortages and lack of adherence to infection control practices have contributed to the outbreaks in nursing homes, experts have said.

“We are really concerned about the lack of oversight in skilled nursing facilities like San Miguel Villa,” said Nicole Howell, executive director of Ombudsman Services of Contra Costa, Solano and Alameda counties. “This underscores the need to improve regulation and oversight — particularly one that specializes in dementia and memory loss.”

The outbreak and death toll at San Miguel Villa is among the largest in East Bay skilled nursing facilities.

East Bay Post-Acute in Castro Valley has had a total of 16 COVID-19-related patient deaths, and 18 patients at Gateway Care and Rehabilitation Center in Hayward have died of the virus.

In San Mateo County, Millbrae Skilled Care has had 14 COVID-related deaths, and more than 100 cumulative infections among patients and 31 cases among health care workers there. But the state data shows there are no infections reported in the last 24 hours at that facility.

In Santa Clara County, 12 patients of Canyon Springs Post-Acute nursing facility in San Jose have died of COVID-19, and at one point 106 patients and staff were infected with the virus. There were no current cases within the last 24 hours, according to the state data.

Update: An earlier version of this story reported at least 15 people had died of COVID-19 at San Miguel Villa. A spokesperson confirmed the state data incorrectly reported that a healthcareworker had died.

Little known Concord fault poses threat to Bay Area refineries, Benicia-Martinez rail bridge…

Little known Concord fault poses big threat

CONCORD — A mysterious earthquake fault slices under central Concord, its jagged, quarter-mile-wide seam running beneath a critical fuel-pumping facility, traversing the edge of a refinery processing 166,000 barrels of crude oil daily, and undercutting strip malls and homes.

While its big sisters, the San Andreas and Hayward fissures, grab the headlines, the Concord Fault — with its 11-mile-long fracture zone stretching from the Carquinez Strait to the Mount Diablo foothills — is also capable of producing a catastrophic earthquake, geologists say. And with critical infrastructure in its path, particularly refineries and a vulnerable railroad bridge not far away, a large seismic event could leave the entire northern half of the state without easy access to fuel — disrupting transportation and the transmission of electricity and water, according to a recent study.

The Concord fissure may be largely ignored by the general public. But not by geologists.

“The Concord Fault is significantly more active than the fault that caused the Napa earthquake,” said Chris Wills of the California Geological Survey, referring to the 6.0 wine country temblor last August that caused more than $400 million in damage. “Nobody would be surprised if a magnitude-6 earthquake happened on the Concord Fault tomorrow.”

Make no mistake, Concord’s contribution to the Bay Area’s geologic activity is significantly smaller than the San Andreas and Hayward zones. Updated U.S. Geological Survey estimates indicate a 3 to 4 percent probability of a magnitude-6.7 or higher earthquake over the next 30 years on the Concord or lower Green Valley Fault, a connected Solano County segment, compared with 6.4 percent for the San Andreas and 14.3 percent for the Hayward Fault.

The Concord Fault creeps a measly 4 to 5 millimeters annually, while the Hayward slips 9 millimeters and San Andreas 25 millimeters.

The last catastrophic temblor on the Contra Costa-Solano combo fault struck more than 400 years ago, but geologists still say it’s important to monitor.

“At some point in time that system has to fail — we just don’t know exactly when,” said David Schwartz with the USGS. Even if the Concord Fault only produces a 5.0 quake, it could cause significant damage, Schwartz said.

The great unknown

On Oct. 23, 1955, a 5.4 quake — the Concord Fault’s last major temblor — was felt from San Jose to Sacramento. It caused $1 million in damage ($8.7 million in today’s dollars) and one fatality, according to the USGS. Windows shattered, brick walls cracked and moved, chimneys shifted and wine bottles crashed from liquor store shelves.

What makes the Concord Fault particularly worrisome to regional planners, so much so that it was highlighted in a December study by the Association of Bay Area Governments, is its potential impact on regional and statewide fuel distribution. Without gasoline, every other crucial need, including water, electricity and transportation, will be affected.

In its report, ABAG studied three theoretical earthquakes — a 7.9 on the San Andreas, a 7.0 on the Hayward and 6.8 on the Concord.

“Originally, we were just going to explore the San Andreas and Hayward faults, but we realized that (there are) a lot of key infrastructure assets in (the Concord) region,” said study author Michael Germeraad, an ABAG resilience planner.

Five Bay Area refineries — all but two are within a couple miles of the fault — processed 235 million barrels of crude in 2012, about 40 percent of the state’s total, according to ABAG. In addition, Kinder Morgan operates a pumping station nearby that receives processed crude from all the refineries and pipes it out to terminals across Northern California and Nevada.

Critical pipelines

That pumping station, a critical piece of fuel infrastructure, lies directly above the Concord Fault.

Built in the 1950s, the station receives products from eight facilities and pumps the refined crude through pipelines. It can store about 1 million barrels, but normal inventory is half of that, said Melissa Ruiz, a Kinder Morgan spokeswoman. Its five outgoing pipelines serve Chico, Fresno, Reno, Sacramento, San Jose, Stockton and surrounding cities, in addition to seven military facilities and public airports.

The company has facilities and pipelines in active fault areas throughout California but has never lost a pipeline or tank to a quake and maintains its infrastructure to industry rules and regulations, Ruiz said.

In its report, ABAG said it had concerns because pipelines can fail due to soil liquefaction — where hard soil loses strength during strong ground shaking — and fault rupture. Knowing pipeline material, age, weld types and other factors would help scientists know where failures are “more likely,” but that information isn’t available.

“Damage to the Concord station would interrupt fuel transmission across the northern half of the state,” the report concluded.

The study also found that if one Bay Area refinery was damaged, they would all likely suffer damage because of their close proximity to each other, and because they are built on similar soils and have similar construction.

“A conservative restoration estimate of damaged refineries is months,” the study found for the Concord quake scenario.

The Tesoro Golden Eagle facility in Martinez sits on 2,206 acres just feet from the fault. Built in 1903, Golden Eagle employs about 650 workers and is the fourth-largest refinery in California.

Spokeswoman Patricia Deutsche said refinery officials are aware it sits next to the fault and a liquefaction zone, but she said the facility follows industry design standards. Piles are driven down hundreds of feet into bedrock, equipment has been retrofitted and the Avon Wharf, an oil terminal located on aging timber piles along the southern shore of Suisun Bay, just received environmental clearance for retrofit up to state quake standards, she said.

Seismic assessments of Bay Area refineries are done every five years, and the building code requirements consider the level of possible ground shaking from any nearby fault, said Gayle Johnson, senior engineer with Simpson Gumpertz & Heger, a national engineering firm.

Johnson, who has investigated the performance of industrial facilities in more than 20 earthquakes worldwide, said since the refinery retrofit programs began in the late 1980s and early 1990s, there has been a “ton of upgrade work done.”

Other impacts

While fuel infrastructure may be the top concern for the region, a large quake could disrupt other major lifelines. The Benicia-Martinez rail bridge, located between the two vehicle spans, is particularly vulnerable, according to ABAG, and could face “significant or complete damage.”

Liquefaction along the Carquinez Strait could cause dredged water channels to slough into the shipping pathways. Runways could rupture at Buchanan Field, which sits adjacent to the fault. Delta levees could breach, creating flooding and impacting drinking water quality, ABAG found.

Two-thirds of the power generated in the region is produced by natural gas facilities, many along the Carquinez Strait.

“In the event natural gas lines are damaged, these facilities will be unable to generate electricity,” the study found.

Still, Wills warns that what will happen during a significant quake on the Concord Fault is largely a mystery.

“How it releases is not that well known,” he said.
