Six were health care workers who encountered the first American known to be infected with bird flu without previous exposure to a sick animal, and the other was a close household contact of the patient. All developed mild respiratory symptoms after their exposure.
A new survey study reveals that people who had two COVID-19 infections were more than twice as likely—and those who had three or more COVID-19 infections were almost four times more likely—to report long COVID as those with one infection.
A new study reveals that 12-18 months after hospitalization for COVID-19, patients show significant cognitive decline comparable to 20 years of aging. MRI scans and blood tests also show brain injury markers and reduced brain volume in these patients. The findings suggest that COVID-19 has lasting effects on brain health, even in those without neurological complications.
Researchers from Weill Cornell Medicine have used a cutting-edge model system to uncover the mechanism by which SARS-CoV-2, the virus that causes COVID-19, induces new cases of diabetes, and worsens complications in people who already have it. The team found that viral exposure activates immune cells that in turn destroy beta cells, the pancreatic cells that produce insulin.
