Cold virus may set the stage for Long COVID


20 Sep 2023

At a Glance Prior infection with a common cold coronavirus may predispose some people to develop Long COVID. The findings identify a potential marker that could help identify people at high risk of developing Long COVID.


Genetic variant associated with absence of COVID-19 symptoms


09 Aug 2023

At least 20% of people infected with SARS-CoV-2, the virus that causes COVID-19, never showed symptoms. These asymptomatic infections could provide clues to how the virus can be quickly cleared from the body. Genetic factors may be involved. However, most studies of genetics and COVID-19 outcomes to date have focused on severe disease.


Delivering Extra Protection Against COVID-19


27 Jul 2023

What you need to know SARS-CoV-2, the virus that causes COVID-19, is covered in spike proteins. These spike proteins interact with a protein called angiotensin-converting enzyme 2 (ACE2) that sits on the surface of human cells. By attaching to ACE2, the virus can infect the human cells. Because ACE2 does not change, the part of the spike protein that interacts with ACE2 is unlikely to change or mutate. This makes the development of “decoy” ACE2 proteins — proteins that bind to SARS-CoV-2 before it can attach to human cells — a promising target for new treatments.


What Long COVID Looks Like in Children and Young Adults


22 May 2023

At least 15 million kids have been infected with SARS-CoV-2, the virus that causes COVID-19, but it is unclear how many of them have had or are living with long COVID. The ailment includes symptoms that linger after COVID-19 or symptoms that come back after an absence of weeks or months. A person might feel short of breath, lose their sense of smell, be unable to think clearly, be tired all the time, or have other maladies that can be traced back to COVID-19.


Rapid Progression of Dementia Following COVID-19


03 May 2023

What you need to know COVID-19 can cause long-term problems with thinking, concentrating, and remembering. This condition is commonly known as “brain fog.” Brain fog after COVID-19 has been studied mostly by observing previously healthy people. In a small study supported by the National Institute of Neurological Disorders and Stroke (NINDS), researchers examined the cognitive impact of COVID-19 on people with dementia. The researchers found that having COVID-19 rapidly accelerated the structural and functional brain deterioration of patients with dementia, regardless of the type of dementia being experienced.

SARS-CoV-2 Variants of Concern in the United States—Challenges and Opportunities


17 Feb 2021

. SARS-CoV-2, like other RNA viruses, constantly changes through mutation, with new variants occurring over time. Generally, when new variants become more common, they do so because of some selective advantage to the virus.
