First reported case of a person getting COVID from a cat
Nature - Scientists in Thailand have established that a tabby passed SARS-CoV-2 to a veterinary surgeon — although such cases of cat-to-human transmission are probably rare. // 29.6.2022
First infection with SARS-CoV-2 is associated with increased risk of acute and post-acute death and sequelae in the pulmonary and extrapulmonary organ systems. However, whether reinfection adds to the risk incurred after the first infection is not clear. Here we use the national health care da... // 17.6.2022
Some people test positive for Covid-19 for weeks. Are they still infectious?
After contracting Covid-19, some people may continue to test positive on rapid tests for 10 days or longer—and experts are split about whether these individuals should continue to isolate past 10 days or just employ safety precautions until they test negative. // 1.6.2022
COVID-19 Autopsies Reveal Underreporting of SARS-CoV-2 Infection and Scarcity of Co-infections
Coronavirus disease 2019 (COVID-19) mortality can be estimated based on reliable mortality data. Variable testing procedures and heterogeneous disease course suggest that a substantial number of COVID-19 deaths is undetected. // 14.4.2022
Clearing the Fog: A Systematic Review on Cognitive Dysfunction in COVID-19
Objective: The systematic review aims to examine the association between COVID-19 and cognitive dysfunction, including the link between the severity of COVID-19 and the occurrence of cognitive impairment and the potential pathophysiological mechanisms related to brain fog among COVID-19 patients. // 25.5.2022
Morbidity and Mortality Weekly Report (MMWR) Post–COVID Conditions Among Adult COVID-19 Survivors Aged 18–64 and ≥65 Years — United States, March 2020–November 2021
This report describes how survivors of COVID-19 were at higher risk for developing many other health conditions. // 24.5.2022
Background The rapid worldwide spread of the mildly pathogenic SARS-CoV-2 Omicron variant has led to the suggestion that it will induce levels of collective imm… // 16.5.2022
”Interpretation Moderately symptomatic Omicron infection is only poorly immunogenic and does not represent a substitute for vaccination.”
The risk of new-onset neuropsychiatric illness after severe COVID-19 is substantial but appears similar to other severe respiratory infections. // 11.5.2022
Effectiveness of influenza vaccination against SARS-CoV-2 infection among healthcare workers in Qatar
A number of studies reported that influenza vaccination is associated with lower risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and/or coronavirus disease 2019 (COVID-19) morbidity and mortality. We conducted a matched, test-negative, case-control study to estimate effectiveness of influenza vaccination, using Abbott’s quadrivalent Influvac Tetra vaccine, against SARS-CoV-2 infection and against severe COVID-19. // 10.5.2022
Approximately 13% of hospitalized COVID patients have serious neurologic symptoms
In a recent study in the journal Critical Care Explorations, the Viral Infection and Respiratory Illness Universal Study (VIRUS): COVID-19 Registry was used to record significant neurologic signs of SARS-CoV-2 infection, as well as prehospital risk factors and outcomes. // 9.5.2022
Microgliosis and neuronal proteinopathy in brain persist beyond viral clearance in SARS-CoV-2 hamster model
Thus, despite the absence of virus in brain, neurons develop signatures of proteinopathies that may contribute to progressive neuronal dysfunction. // 16.4.2022
Long-term mortality following SARS-CoV-2 infection: A national cohort study from Estonia
People infected with SARS-COV-2 had more than three times the risk of dying over the following year compared with those who remained uninfected. // 28.4.2022
