The Health 202: Genetic tracing could show how coronavirus spread through White House

White House spokesman Judd Deere said tracing has been done for people who had contact with Trump. But it’s the kind recommended by the Centers for Disease Control and Prevention, which involves merely tracking people who were nearby those known to be infected.

“Contact tracing has been done by the White House Medical Unit consistent with CDC guidelines,” Deere said, though The Post has reported many of the hundreds of people potentially exposed to the president found out via media reports of his diagnosis.

Coding coronavirus samples would give a clear picture of whether recent White House events were so-called “superspreaders.”

This is an approach researchers have tried around the country.

They’ve watched the virus accumulate a catalogue of mutations as it moved through Zip codes in the Houston area. They’ve used genetic sequencing to trace how the virus spread outward from a conference in Boston, infecting people from Alaska

PHILADELPHIA — A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain — which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer’s Disease — that could be targeted for new therapies. The study was published today in Science.

Alzheimer’s disease (AD) is a neurodegenerative disease characterized by a buildup of proteins, called tau proteins, in certain parts of the brain. Following an examination of human brain tissue samples from a deceased donor with an unknown neurodegenerative disease, researchers discovered a novel mutation in
