Hybrid immunity and strategies for COVID-19 vaccination
The Lancet Infectious Diseases – Since April, 2022, BA.2.12.1, BA.4, and BA.5 subvariants of the omicron (B.1.1.529) SARS-CoV-2 variant of concern have been spreading globally with increased viral fitness and transmissibility. Omicron BA.5 subvariant is currently the predominant COVID-19 threat worldwide. With the emergence of the antigenically distinct variants of concern, either natural immunity or […]

Test predicts which COVID-19 patients will grow worse, Stanford Medicine study find
Stanford Medicine – Elevated virus levels in hospitalized COVID-19 patients’ blood predicts worsening respiratory symptoms and suggests ongoing viral replication in later disease stages, Stanford Medicine-led study says. A one-time test could predict which people hospitalized with COVID-19 are likely to worsen significantly during their stay, even if they were admitted with relatively mild symptoms, […]

These scientists traced a new coronavirus lineage to one office — through sewage
Nature – Virologist Dave O’Connor admits that he was getting desperate when he started asking dog owners for poo samples. For much of 2022, O’Connor, at the University of Wisconsin–Madison, and his colleagues have been tracking a heavily mutated variant of SARS-CoV-2, the virus that causes COVID-19. Early this year, they discovered the variant in […]

Lingering cardiac involvement in previously well people after mild COVID-19
Nature Medicine – Lingering cardiac symptoms, including exercise intolerance, tachycardia and chest pain, are increasingly recognized as post-acute COVID-19 sequelae1. In patients with a severe course of initial illness, accrued cardiac injury and pre-existing conditions readily explain cardiac symptoms. However, signs of cardiac injury such as elevated troponin levels and structural heart disease are rare […]

How COVID-19 stole our sense of smell
Chemical Engineering News – SARS-CoV-2 has left thousands with a distorted or lost sense of smell. This population is helping researchers identify what happens when smell goes wrong and what might help. Researchers are getting a clearer idea of how. This understanding and a growing awareness of olfactory disorders could help others facing smell loss […]
