Live tracker notes COVID cases, deaths by congressional districts

Live tracker notes COVID cases, deaths by congressional districts

Researchers at the Harvard Center for Population and Development Studies, Harvard Center for Geographic Analysis at the Institute for Quantitative Social Science, and Microsoft AI for Health have created a COVID-19 live tracker that monitors the current status of virus cases and deaths, as well as the reduction of new cases, in U.S. congressional districts.

It is the first compilation of this data, which could be key for elected officials and their constituents to monitor and develop testing strategies, vaccine deployment strategies, and other measures to enable their districts to open safely.

“By connecting previously separate reporting geographies for public health and electoral data, this data set represents an important effort,” said Gary King, director of the Institute for Quantitative Social Science, and Weatherhead University Professor at Harvard.

“As the COVID-19 pandemic continues to spiral out of control in the U.S. (and elsewhere), innovations such as this, which combine both science and public policy, are sorely needed,” said Douglas Richardson, distinguished researcher at Harvard Center for Geographic Analysis.

Nearly a year into the global pandemic, data breakdown by U.S. congressional districts has not been readily available. S.V. Subramanian and researchers in the Geographic Insights Lab, who had previously applied a geographical method to convert county-level opioid prescriptions data to the congressional district level, noticed that similar data was lacking for the pandemic. The team developed COVID-19 metrics for congressional districts and, working with Geographics Analysis center member Wendy Guan, developed a dashboard to share the data. John Kahan, vice president and chief data analytics officer at Microsoft, noted that the team’s work was similar to a project underway at Microsoft, and the groups joined forces to provide mutual scientific support, such as methodologies and data verification.

“The research provides critical insight,” said Nydia M. Velázquez, Congresswoman of New York’s 7th Congressional District and chair of the House Small Business Committee. “Because of this information, the House Small Business Committee can better examine the efficacy of federal programs in reaching the areas most impacted by this virus. Data like this is critical to policymakers, as it improves our ability to legislate changes that ensure aid is going to those that need it most.”

The live tracker contains COVID-19 metrics for each congressional district, such as confirmed cases and deaths per 100K/1M people, cumulative cases and deaths, and new cases and deaths. It also provides the progress-to-zero metric to monitor progress on addressing the pandemic.

The tracker gives elected representatives and their constituents precise information about COVID’s spread in their district. In Texas, for example, a graph reflecting infection by county gives the initial impression that west Texas is doing better than east Texas. When broken down by congressional district, however, the northwestern and southwestern parts of the state actually have the greatest number of COVID cases. The two districts with the most cases “are not even geographically close to the counties with the highest number of cases (Harris County and Dallas County),” said Weixing Zhang of the Harvard Center for Population and Development Studies.

“We’ve heard from many Congressional members that they want to have a better understanding of the disease’s spread in their districts, and so do their constituents,” said Kahan. “The data will be key for policymakers to create policies to ensure safer communities, and allow the public to see the progress we are making together.”

Words Matter When Discussing Alcohol Issues: A New Stigma-Free Vocabulary for Better AUD Outcomes

Image
Word choice may seem out of place among the myriad factors that can influence outcomes for a complex condition like alcohol use disorder (AUD). In fact, the stigma created by the language that is used to describe alcohol problems can decrease many people’s willingness to seek help for alcohol problems. It also can affect how people with AUD are treated in all aspects of life. “Stigmas are the negative attitudes toward people that are based on certain distinguishing characteristics,” says National Institute on Alcohol Abuse and Alcoholism (NIAAA) Director George F. Koob, Ph.D. “More than a decade of research has shown that stigma contributes significantly to negative health outcomes and can pose a barrier to seeking treatment for mental illness or substance use disorders.” In the United States, nearly 90 percent of people with substance use disorders and 35 percent of people with serious mental illness do not receive treatment. In a recent article published in  Neuropsychopharma...

‘Massive-scale mobilization’ necessary for addressing climate change, scientists say

Image
A year after a global coalition of more than 11,000 scientists declared a climate emergency, Oregon State University researchers who initiated the declaration released an update today that points to a handful of hopeful signs, but shares continued alarm regarding an overall lack of progress in addressing climate risks. “Young people in more than 3,500 locations around the world have organized to push for urgent action,” said Oregon State University’s William Ripple, who co-authored “The Climate Emergency: 2020 in Review,” published today in Scientific American. “And the Black Lives Matter movement has elevated social injustice and equality to the top of our consciousness. “Rapid progress in each of the climate action steps we outline is possible if framed from the outset in the context of climate justice – climate change is a deeply moral issue. We desperately need those who face the most severe climate risks to help shape the response.” One year ago, Ripple, distinguished profess...

Researchers advance science behind gut health and prebiotics

Image
When it comes to improving human gut health, approaches and the success of these approaches are based largely on an individual’s gut ecosystem: the bacteria present, its diversity and other factors. Therefore, trying to improve gut health through application of prebiotics or probiotics can have wildly variable results based on gut flora composition. Bruce Hamaker , director of the Whistler Center for Carbohydrate Research and Distinguished Professor of Food Science, and Thaisa Moro Cantu-Jungles, his postdoctoral research associate, recently discovered a way to select prebiotic fibers that have the potential to provide improvement of gut health where everyone would benefit. Their study, conducted in vitro, showed an increase in butyrate-producing bacteria with a selected fiber using this new approach. Butyrate is a short-chain fatty acid that supports many of the body’s essential functions from regulating the immune system to digestive health. In donors’ gut flora where these bacter...
