RAW INTERVIEW: Study author discusses dementia-like issues found in COVID patients

Dr. Sudha Seshadri, founding director of the Glenn Biggs Institute for Alzheimer's and Neurodegenerative Diseases at UT Health San Antonio, discusses a study of older adults in Argentina. It found a surprising amount of dementia-like changes in memory and thinking for at least six months after contracting COVID-19.

The World Health Organization is developing a team of about 20 scientists who will be tasked with uncovering the origins of the COVID-19 outbreak -- and officials warned that time could be running out, according to a report.

The Wall Street Journal reported Sunday that officials from the U.N.’s public-health arm have warned that the world may never know the virus’ origins.

Lawrence Gostin, faculty director of the O’Neill Institute for National and Global Health Law at Georgetown University, told the paper that it is unclear if the team’s mandate will be enough to actually make progress in the investigation.

"China still holds all the cards, the WHO lacks power and it’s inconceivable to me that a new committee will be able to negotiate access to China…This is building a beautiful committee with nowhere to go," he said.

The outbreak has also created additional tension between the U.S. and China. The Journal’s report said the Biden administration has been pressing WHO's director Tedros Adhanom Ghebreyesus to renew the inquiry. The WHO did not immediately respond to a late email from Fox News.

Full remarks: Biden addresses UN General Assembly

President Joe Biden gave his first address to the U.N. General Assembly and called on nations to move quickly to tackle the COVID-19 pandemic, climate change and other issues facing the world, on Sept. 21, 2021, in New York City.

An unidentified WHO spokesman told the paper that the team’s priority "needs to be data and access in the country where the first reports were identified."

The U.S. intelligence community earlier this month failed to conclusively identify the origin of the coronavirus following a 90-day investigation ordered by President Biden and experts are divided on why. A report by the Office of the Director of National Intelligence (ODNI) found that officials were unable to rule whether the virus escaped from a lab or spread to humans through an infected animal.

Biden orders US intelligence officials to redouble efforts to find origin of COVID-19 pandemic

President Joe Biden on May 26 ordered U.S. intelligence officials to redouble their efforts to investigate the origins of COVID-19, including any possibility that the virus may have emerged from a Chinese laboratory.

Klon Kitchen, a former intelligence officer with the ODNI, told Fox News it is in China's interest to continue to bar access to uncovering the origin of the virus.

"China is highly incentivized and capable of denying us this information," Kitchen said. "They're incentivized to deny us this information because no matter what it is – whether it was a wet market or a biological facility as its origin – it's embarrassing to the Chinese Communist Party."

The Journal’s report pointed out that Chinese President Xi Jinping addressed the UN General Assembly last week and said his country will "continue to support and engage in global science-based origins tracing and stands firmly opposed to political maneuvering in whatever form."
