COVID-19

Two distinct diagnostic tests, a host/pathogen RNA sequencing platform, and spatially-resolved tissue mapping tools were created by a multidisciplinary team of Weill Cornell Medicine and NewYork-Presbyterian Hospital-led researchers and used to map SARS-CoV-2 infections at the height of the initial COVID-19 outbreak in New York City.

A team led by investigators at Weill Cornell Medicine and NewYork-Presbyterian has used advanced technology and analytics to map, at single-cell resolution, the cellular landscape of diseased lung tissue in severe COVID-19 and other infectious lung diseases.

Last spring, as the COVID-19 pandemic hit New York City with full force, Dr. Daniel MacGowan, a neurologist specializing in neuromuscular disease, was asked to consult in a COVID recovery ward.

As the COVID-19 pandemic enters its second year, scientists are urgently investigating ways to detect signs of the SARS-CoV-2 virus before an outbreak emerges.

Antibodies that guard against COVID-19 can transfer from mothers to babies while in the womb, according to a new study from Weill Cornell Medicine and NewYork-Presbyterian researcher.

Severe COVID-19 involves a distinctive reprogramming of gene activity in infected patients‘ immune cells, according to a study led by researchers at Weill Cornell Medicine.

With the COVID-19 vaccines rolling out across the country and more people getting vaccinated, many are wondering how long it takes for the vaccines to provide protection.

Cases of symptomatic COVID-19 were extremely low among children and staff at a network of YMCA day camps in North Carolina that took precautions like masking and physical distancing, with close to zero transmissions occurring at the camps.

As the coronavirus vaccine rolls out across the country, an infectious disease expert answers questions about its safety and when it’s likely to be available to the general public.

Human organoids, tiny organ-like structures grown in the laboratory, can be used to identify potential COVID-19 drugs in an automated, high-throughput fashion.

T-cells taken from the blood of people who recovered from a COVID-19 infection can be successfully multiplied in the lab and maintain the ability to effectively target proteins that are key to the virus’s function.

When a patient is hospitalized with COVID-19, signs of damage to the right side of the heart may indicate a greater risk of death, according to a study from investigators at Weill Cornell Medicine and NewYork-Presbyterian.

Cancer patients who contracted COVID-19 during the height of the pandemic in New York City had similar outcomes to other patients with COVID-19.

It began as a spark of interest in remote healthcare, gained momentum four years ago with the introduction of a suite of digital health services, then exploded when COVID-19 strained the system, making hospital and doctor visits anything but routine. Today, telemedicine—as a panel of experts at an Oct. 1 Weill Cornell Medicine webinar agreed—is no longer a futuristic idea but an immediate and vital tool for doctors and patients alike.

The amount of SARS-CoV-2 virus, or “viral load,” in cancer patients and in the general inpatient population upon hospital admission may predict their risk of dying of the infection, according to a study led by researchers at Weill Cornell Medicine and NewYork-Presbyterian.

A study by investigators at Weill Cornell Medicine and NewYork-Presbyterian aims to answer one of COVID-19’s biggest mysteries: why do some people become severely ill, while others have no symptoms?

Weill Cornell Medicine has awarded eight grants of $100,000 each to faculty for a variety of research projects on COVID-19, funded by the institution’s Board of Overseers and additional donors. The grants will support studies aimed at understanding fundamental aspects of the disease, the body’s immune response and social determinants of health that affect COVID-19 outcomes. 

Dr. Kristen Marks, an associate professor of medicine in the Division of Infectious Diseases at Weill Cornell Medicine and associate attending physician at the medical center, leads the team conducting Moderna Therapeutics’s phase 3 COVID-19 vaccine trial at NewYork-Presbyterian/Weill Cornell Medical Center—one of dozens of medical centers around the U.S. where this still-experimental vaccine will be tested. 

My wife thinks she got me sick, and I think I got her sick. She was serving on a grand jury—in a room with dozens of people who had sniffles and coughs—and one afternoon she called me and said she’d been sent home with a fever and didn’t feel well. 

Home health care workers faced increased risks to their physical, mental and financial well-being while providing essential care to patients during the COVID-19 pandemic, according to researchers at Weill Cornell Medicine, Cornell Tech and Cornell University.
