Characteristics of long COVID among older adults: a cross-sectional study
International Journal of Infectious Diseases – 2333 individuals were evaluated at an average of 5 months [146 days (95% CI 142-150)] following COVID-19 onset. Mean age was 51 and 20.5% were>65 years. Older adults were more likely to be symptomatic, with most common symptoms being fatigue (38%) and dyspnea (30%). They were more likely to […]

Nature – The Omicron variant has been associated with reduced vaccine effectiveness (VE) against mild disease with rapid waning. Meanwhile Omicron has also been associated with milder disease. Protection against severe disease has been substantially higher than protection against infection with previous variants. We used a test-negative case-control design to estimate VE against hospitalisation with […]

Viral loads in clinical samples of men with monkeypox virus infection: a French case series
The Lancet – Monkeypox virus (MPXV) is currently spreading among men who have sex with men, outside of sub-Saharan Africa, and close contact during sex seems to be one of the key pathways of viral transmission in the current outbreak. Our aim was to describe the distribution of MPXV in the human body, as it […]

Nature – Understanding the epidemic growth of the novel SARS-CoV-2 Omicron variant is critical for public health. We compared the ten-day secondary attack rate (SAR) of the Omicron and Delta variants in households using Norwegian contact tracing data, December 2021 – January 2022. Omicron SAR was higher than Delta, with a relative risk (RR) of […]

Translational Research and Clinical Interventions – Coronavirus disease 2019 (COVID-19) has caused >3.5 million deaths worldwide and affected >160 million people. At least twice as many have been infected but remained asymptomatic or minimally symptomatic. COVID-19 includes central nervous system manifestations mediated by inflammation and cerebrovascular, anoxic, and/or viral neurotoxicity mechanisms. More than one third […]

The Lancet – Singapore offered the BNT162b2 vaccine (tozinameran; Pfizer-BioNTech) to adolescents aged 12–17 years in May 18, 2021, and extended booster vaccines to this group in Jan 21, 2022. Literature on the effectiveness of primary series and booster vaccination among adolescents is scarce outside of Europe and North America. We aimed to determine primary […]

CDC MMWR Enterovirus D68 (EV-D68) caused biennial outbreaks of severe respiratory illness and acute flaccid myelitis (AFM) in the United States in 2014, 2016, and 2018. After an extended period of low EV-D68 circulation during the COVID-19 pandemic, surveillance data suggest increased detection of rhinovirus/enterovirus and EV-D68, concurrent with increased emergency department visits by children […]

JAMA – Question Is SARS-CoV-2 seropositivity associated with symptoms of myalgic encephalomyelitis and/or chronic fatigue syndrome (ME/CFS) in children and adolescents? Findings This cross-sectional study of hospital-based SARS-CoV-2 seroprevalence surveys in Germany compared seropositive and seronegative children and adolescents and identified an excess of possible ME/CFS symptoms with serological evidence of preceding SARS-CoV-2 infection. This association almost […]

Remdesivir resistance in transplant recipients with persistent COVID-19
Clinical Infectious Diseases – New mutations conferring resistance to SARS-CoV-2 therapeutics have important clinical implications. We describe the first cases of an independently acquired V792I RNA-dependent RNA polymerase mutation developing in renal transplant recipients after remdesivir exposure. Our work underscores the need for augmented efforts to identify concerning mutations and address their clinical implications. Download […]

CDC – Increases in severe respiratory illness and acute flaccid myelitis (AFM) among children and adolescents resulting from enterovirus D68 (EV-D68) infections occurred biennially in the United States during 2014, 2016, and 2018, primarily in late summer and fall. Although EV-D68 annual trends are not fully understood, EV-D68 levels were lower than expected in 2020, […]
