What is the prevalence of contraindications to Paxlovid among hospitalized COVID-19 patients?

Researchers examined the prevalence of contraindications to nirmatrelvir-ritonavir (Paxlovid) in hospitalized coronavirus disease 2019 (COVID-19) patients.

Study describes distinct pattern of ongoing respiratory syncytial virus transmission in the Netherlands after the COVID-19 pandemic

Researchers assessed respiratory syncytial virus (RSV) transmission after the coronavirus disease 2019 (COVID-19) pandemic in the Netherlands.

Comparing post–COVID-19 symptoms two years after SARS-CoV-2 infection

Researchers compared the presence of post–coronavirus disease 2019 (COVID-19) symptoms among hospitalized and non-hospitalized patients in Spain.

Novel, student-driven, contact-tracing program reduced COVID-19 exposures

Epidemiologists at the University of Illinois Chicago (UIC) developed and implemented a novel, student-driven, contact-tracing program that reduced COVID-19 exposures and infections on the campus during the 2020-2021 school year. Results from the program, which deployed UIC students to conduct both COVID-19 case investigations and contact tracing among non-clinical campus members, were published today in the American Journal of Infection Control (AJIC).

Protection afforded by SARS-CoV-2 infection against reinfection when Omicron BA.5 was the dominating subvariant in Scania county, Sweden

Researchers from Sweden conducted a cohort study to evaluate the protection granted by previous SARS-CoV-2 Omicron subvariant infections against reinfections among individuals vaccinated between June and August 2022.

Experts investigate the role of IL-26 in COVID-19

Researchers at Karolinska Institutet in Sweden have shown that patients with acute COVID-19 infection have increased levels of the cytokine IL-26 in their blood. Moreover, high IL-26 levels correlate with an exaggerated inflammatory response that signifies severe cases of the disease. The findings, which are presented in Frontiers in Immunology, indicate that IL-26 is a potential biomarker for severe COVID-19.

Researchers identify a conserved site on SARS-CoV-2 spike that a broadly neutralizing macrocyclic peptide can target

Researchers explored the efficiency of a macrocyclic peptide in inhibiting the SARS-CoV-2 spike protein.

SARS-CoV-2 RNA levels, IFN-1, ISGs, and NF-κB gene responses within the respiratory tract of mild and severe COVID-19 patients

Researchers characterized the expression of IFN-1 and IFN-2, ISGs, and NF-κB in the upper respiratory tracts of patients with mild and severe COVID-19, to understand innate immune responses to SARS-CoV-2 infections.

Experts highlight the need to study and develop treatments for fungal infections

Fungi in the soil cause a significant number of serious lung infections in 48 out of 50 states and the District of Columbia, including many areas long thought to be free of deadly environmental fungi, according to a study by researchers at Washington University School of Medicine in St. Louis.

Study finds a lower compliance rate with recently released guidelines for COVID-19 care

Uptake of national guidelines for the treatment of children hospitalized with COVID-19 fell well below what would typically be expected, report researchers at the Medical University of South Carolina (MUSC) and elsewhere in Pediatrics.

Omicron BA.2 causes more symptoms and a greater disruption to daily life

In a recent study published in the Nature Communications journal, researchers monitored the changing symptom profiles associated with different severe acute respiratory syndrome CoV-2 (SARS-CoV-2) variants, especially Omicron subvariants BA.1 and BA.2.

Among US veterans with COVID-19, few used antivirals or monoclonal antibodies

In a recent study published in the journal JAMA Network, researchers in the United States investigated factors that restricted the use of antivirals directed at severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States (US) between January and February 2022.

SARS-CoV-2 ‘Deltacron’ variant exhibits immune-escape properties similar to Omicron BA.1

The SARS-CoV-2 Deltacron does not exhibit higher transmissibility or immune evasion than the Omicron BA.1 variant.

Study reveals neglected or late TB diagnoses related to COVID-19

In a recent study published in the journal BMJ Medicine, researchers modeled changing patterns in sex- and age-stratified new and relapse tuberculosis (TB) case notifications reported to the World Health Organization (WHO) for 45 nations with high TB, TB/human immunodeficiency virus (HIV) and multidrug-resistant TB (MDR-TB) burden between 2013 and 2019 due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections.

SARS-CoV-2 antibodies persist in breast milk following two and three COVID-19 vaccine doses

A new study assesses anti-SARS-CoV-2 antibody levels in breast milk obtained from lactating individuals following two or three COVID-19 vaccine doses.

Jynneos vaccine for Monkeypox not linked to hospitalization, serious cardiac events

In a recent study posted to the medRxiv* preprint server, researchers investigated the incidence of cardiac AESIs (adverse events of special interest) among Kaiser Permanente Northwest (KPNW) members who had received JYNNEOS vaccinations against the monkeypox (MPX) virus.

Stress from fears about Covid-19 led to anxiety and depressive symptoms in pregnant women

A study that assessed stress, anxiety and depressive symptoms in pregnant women from seven Western countries during the first major wave of the Covid-19 pandemic (April 17 to May 31, 2020) shows that stress from fears about Covid-19 led to anxiety and depressive symptoms above normal levels.
