Rising SARS-CoV-2 Seroprevalence and Patterns of Cross-Variant Antibody Neutralization in UK Domestic Cats

Recent evidence confirming cat-to-human SARS-CoV-2 transmission has highlighted the importance of monitoring infection in domestic cats. Although the effects of SARS-CoV-2 infection on feline health are poorly characterized, cats have close contact with humans, and with both domesticated and wild animals. Accordingly, they could act as a reservoir of infection, an intermediate host and a source of novel variants. To investigate the spread of the virus in the cat population, serum samples were tested for SARS-CoV-2 antibodies by ELISA and a pseudotype-based virus neutralization assay, designed to detect exposure to variants known to be circulating in the human population. Overall seroprevalence was 3.2%, peaking at 5.3% in autumn 2021. Variant-specific neutralizing antibody responses were detected with titers waning over time. The variant-specific response in the feline population correlated with and trailed the variants circulating in the human population, indicating multiple ongoing human-to-cat spill-over events.

Position paper on management of personal data in environment and health research in Europe.

Management of datasets that include health information and other sensitive personal information of European study participants has to be compliant with the General Data Protection Regulation (GDPR, Regulation (EU) 2016/679). Within scientific research, the widely subscribed'FAIR' data principles should apply, meaning that research data should be findable, accessible, interoperable and re-usable. Balancing the aim of open science driven FAIR data management with GDPR compliant personal data protection safeguards is now a common challenge for many research projects dealing with (sensitive) personal data. In December 2020 a workshop was held with representatives of several large EU research consortia and of the European Commission to reflect on how to apply the FAIR data principles for environment and health research (E&H). Several recent data intensive EU funded E&H research projects face this challenge and work intensively towards developing solutions to access, exchange, store, handle, share, process and use such sensitive personal data, with the aim to support European and transnational collaborations. As a result, several recommendations, opportunities and current limitations were formulated. New technical developments such as federated data management and analysis systems, machine learning together with advanced search software, harmonized ontologies and data quality standards should in principle facilitate the FAIRification of data. To address ethical, legal, political and financial obstacles to the wider re-use of data for research purposes, both specific expertise and underpinning infrastructure are needed. There is a need for the E&H research data to find their place in the European Open Science Cloud. Communities using health and population data, environmental data and other publicly available data have to interconnect and synergize. To maximize the use and re-use of environment and health data, a dedicated supporting European infrastructure effort, such as the EIRENE research infrastructure within the ESFRI roadmap 2021, is needed that would interact with existing infrastructures.

Using big data analytics to explore the relationship between government stringency and preventative social behaviour during the COVID-19 pandemic in the United Kingdom

We evaluated the association between preventative social behaviour and government stringency. Additionally, we sought to evaluate the influence of additional factors including time, need to protect others (using the reported number of COVID-19 deaths as a surrogate measure) and reported confidence in government handling of the COVID-19 pandemic. We used repeated national cross-sectional surveys the UK over the course of 41 weeks from 1st April 2020 to January 28th, 2021, including a total of 38,092 participants. Preventative social behaviour and government stringency index scores were significantly associated on linear regression analyses (R2 =0.6468, p<0.001, and remained significant after controlling for the effect of reported COVID-19 deaths, confidence in government handling of the pandemic, and time (R2=0.898, p<0.001). Longitudinal data suggest that government stringency is an effective tool in promoting preventative social behaviour in the fight against COVID-19.

International attitudes on COVID-19 vaccination: repeat national cross-sectional surveys across 15 countries

ObjectiveTo examine the general publics views around willingness to receive COVID-19 vaccines and concerns regarding their safety. DesignRepeat cross-sectional surveys. SettingOnline surveys in Australia, Canada, Denmark, Finland, France, Germany, Italy, Japan, Netherlands, Norway, Singapore, South Korea, Spain, Sweden and the United Kingdom ParticipantsNational samples of adults aged >=18 years in November 2020 and January 2021. Main outcomes measuresThe proportion of adults reporting: willingness to receive a COVID-19 vaccination; concern regarding side-effects from vaccinations; concerns over contraction COVID-19, and beliefs around vaccine provision in their country. Changes between the November and January surveys are also reported. ResultsAcross the 15 countries, the proportion of respondents reporting they would have the COVID-19 vaccine increased from 40.7% (range: 25.0-55.1) to 55.2% (range: 34.8-77.5), proportion reporting worried about the side-effects of vaccine decreased from 53.3% (range: 42.1-66.7) to 47.9% (range: 28.0-66.1). On the second survey, willingness to receive vaccine remained low in females (49.4%, range: 30.2-79.1), aged 18-39 years (42.1%, range: 25.9-71.7), those not working or unemployed (48.9, range: 18.8-67.0), students (45.9%, range: 22.8-70.0), and those with children at home (46.5%, range: 32.4-68.9). Concerns regarding safety of vaccine remained high in females (53.7%, range: 31.8-70.4), aged 18-39 years (50.8%, range: 28.2-60.7), aged 40-64 years (51.3%, range: 30.7-68.5), those working (50.5%, range: 26.7-65.0), those not working or unemployed (53.3, range: 35.4-73.8) and those with children at home (55.8%, range: 36.5-64.7). ConclusionCOVID-19 vaccine hesitancy decreased considerably over a relatively short time coinciding with the discovery of effective vaccines. The public remain concerned about their safety, and public health messaging will need to emphasis their safety especially amongst females, parents and younger adults.

Bilateral pararhinotomy with middle meatal antrostomy of the maxillary sinus in a rabbit (Oryctolagus cuniculus) with chronic rhinitis.

CASE DESCRIPTION: A 4-year-old spayed female mixed-breed rabbit was evaluated because of a 3-year history of sneezing and nasal discharge that were refractory to medical management. CLINICAL FINDINGS: Signs of chronic left-sided rhinitis and sinusitis were observed on physical examination and confirmed by CT evaluation. Lysis of the rostral aspect of the left maxillary bone and destruction of nasal turbinates were evident on CT images. TREATMENT AND OUTCOME: Pararhinotomy of the left maxillary sinus through the facies cribrosa was performed. Purulent material was removed from the maxillary sinus recesses, a middle meatal antrostomy was completed to allow permanent drainage into the left middle nasal meatus, and the tissues were closed routinely. Microbial culture of a sample from the maxillary sinus recesses revealed Bordetella bronchiseptica, undetermined fastidious nonenteric bacteria, and Streptococcus viridans. Medical management was continued, and nasal discharge resolved but sneezing persisted. Increased sneezing and bilateral nasal discharge developed 1.5 years later; CT examination revealed right-sided rhinitis, and culture of a nasal swab sample revealed Bordetella spp, Staphylococcus spp, and Micrococcus spp. Right-sided pararhinotomy and middle meatal antrostomy were performed, and medical management continued. A subsequent recurrence was managed without additional surgery; 4 years after the initial surgery, the rabbit was still receiving medical treatment, with mild intermittent nasal discharge and sneezing reported. CLINICAL RELEVANCE: This report describes a surgical approach for treatment of chronic rhinitis in companion rabbits with maxillary sinus involvement that included creation of a permanent drainage pathway from the maxillary sinus to the middle nasal meatus.
