Covid 19 special public health surveillance bulletin january 2022 // 18.1.2022 ”ZAF data from 56,164 Covid-19-related hospital found that the admission rate for children under the age of four was 49% higher during the Omicron wave than for Delta.”

Nature - News of a ‘super variant’ combining Delta and Omicron spread rapidly last week, but researchers say it never existed and the sequences may have resulted from contamination. // 21.1.2022

A recent study, currently available on bioRxiv* preprint server, shows that a novel protease inhibitor known as nirmatrelvir has potent activity against Omicron variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but also other variants evaluated in this paper – which supports its potential role in reducing the disease burden from coronavirus disease 2019 (COVID-19). // 21.1.2022

A new bioRxiv* preprint study led by Michelle Monje of Stanford University in California finds that a mild COVID-19 infection can produce long-term neurological damage. Persistent cognitive complications are one of many symptoms of long COVID, and the latest results suggest the severity of COVID-19 induced brain fog is similar to cancer’s “chemobrain.” // 16.1.2022

Researchers investigate the progression of infection in students and employees who tested positive for SARS-CoV-2 at Boston University. // 16.1.2022

As the Government cuts the COVID isolation period to 5 days, researchers warn that 1 in 3 people may still be infectious after the 5-day quarantine period. // 15.1.2022

A new study describes the expected distribution of viral emission of COVID-19 by an infected population of people who were either silent, speaking softly, or loudly, to determine factors influencing risks of viral transmission. // 14.1.2022

Researchers screen several systemic autoantibodies to assess their association with the severity of COVID-19. // 13.1.2022

A recent groundbreaking research paper published in the journal Nature Communications reveals the association of circulating SARS-CoV-2-specific T cells at exposure with lack of infection – implying the protective role for cross-reactive immune T cells in coronavirus disease 2019 (COVID-19) and opening the door for second-generation vaccines that could circumvent spike-antibody immune escape variants. // 11.1.2022
