SARS-CoV-2 fragments may cause problems after infection


27 Feb 2024

Most COVID-19 cases are mild, but many still lead to life-threatening complications. At a Glance: - Researchers found that fragments of SARS-CoV-2 left behind after the immune system fights off infection may continue to trigger immune responses. - The findings help explain some unusual aspects of COVID-19 and suggest a previously unappreciated way that viruses can make people sick.


Severe COVID-19 May Cause Long-Term Immune System Changes


30 Nov 2023

What you need to know In a small study supported by the National Institute of Allergy and Infectious Diseases (NIAID), severe cases of COVID-19 were shown to cause long-lasting changes to the immune system. Researchers found that severe cases of COVID-19 can change which genes are turned on or off in certain stem cells. The study focused on stem cells that produce white blood cells, a part of the immune system. The stem cells of people who recovered from severe COVID-19 produced more white blood cells — which then produced more inflammatory signals — than the cells of healthy counterparts.

SARS-CoV-2 infects coronary arteries, increases plaque inflammation


28 Sep 2023

NIH-funded research sheds light on the link between COVID-19 infection and increased risk of cardiovascular disease and stroke SARS-CoV-2, the virus that causes COVID-19, can directly infect the arteries of the heart and cause the fatty plaque inside arteries to become highly inflamed, increasing the risk of heart attack and stroke, according to a study funded by the National Institutes of Health. The findingsexternal link, published in the journal Nature Cardiovascular Research, may help explain why certain people who get COVID-19 have a greater chance of developing cardiovascular disease, or if they already have it, generate more heart-related complications.


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.

Association of Mask Mandates and COVID-19 Case Rates, Hospitalizations, and Deaths in Kansas


23 Jun 2021

This study examined the association between mask mandates in Kansas counties and COVID-19 cases, hospitalizations, and deaths. The Kansas executive order that took effect on July 3 was adopted by only 15 counties, and 68 counties did not have a mandate through October. A second mask mandate order took effect on November 25, and 40 additional counties adopted it.




COVID-19 Vaccination of Health Care Personnel as a Condition of Employment A Logical Addition to Institutional Safety Programs


08 Jun 2021

The consequences of the SARS-CoV-2 pandemic have been far-reaching, particularly among health care personnel (HCP) and within health care settings. HCP have been directly affected, sustaining occupationally acquired COVID-19 infections, and indirectly through a substantial alteration in health care delivery. With the advent of highly effective and safe SARS-CoV-2 vaccines, case rates and hospitalization rates are declining, and the promise of a return to some semblance of pre–COVID-19 health care is growing. Recently, several medical centers have announced a requirement for SARS-CoV-2 vaccination of all HCP (allowing for medical and religious exemptions), and the impending licensure of the mRNA SARS-CoV-2 vaccines (following the previous Emergency Use Authorization [EUA]) will move many other centers to consider a similar policy. A recent outbreak in a skilled nursing facility attributed to an unvaccinated HCP member clearly illustrates the risk unvaccinated HCP can pose to their patients and other HCP.1




We are scheduling training with them this week on how to generate the report.


07 Jun 2021

The Centers for Disease Control and Prevention (CDC) recently issued guidance that fully vaccinated individuals can safely remove masks and end social distancing in most indoor settings.1 Educational facilities and businesses are faced with whether and how to differentiate between vaccinated and unvaccinated individuals, including requiring proof of vaccination. Mandatory vaccination has historically served as a tool to reach and sustain high immunization coverage and to prevent transmission in K-12 schools, colleges/universities, and health care facilities. Vaccine mandates could extend to workers and customers in businesses to ensure safer environments. This Viewpoint examines the epidemiologic, public health, and legal considerations for mandatory SARS-CoV-2 vaccinations in each setting.




Mix-and-match COVID vaccines trigger potent immune response


19 May 2021

Preliminary results from a trial of more than 600 people are the first to show the benefits of combining different vaccines.




Even Partial COVID-19 Vaccination Protects Nursing Home Residents


17 May 2021

A CDC analysis has shown that a single dose of the Pfizer-BioNTech COVID-19 vaccine protected medically vulnerable nursing home residents as well as it did general adult populations that were evaluated in other efficacy and effectiveness studies.
