The survival of virus present in secondary effluents discharged into a cypress dome was studied. Isolations were made from concentrates of water drawn from 10-foot (304.80 cm) deep wells. Data presented show vertical and lateral virus movement as well as survival within the dome for 28 days during a period of heavy rains when no effluent was being applied. Due to the inefficiency of virus concentration procedures, it is proposed that much of the virus present was probably not demonstrated. A rapid, relatively inexpensive concentration technique for sewage influents and effluents is discussed.

Background: COVID-19 was first identified in Wuhan, China, in December 2019, where it spread over a wide geographic area until it reached the status of a pandemic in 2020. We postulated that patients who were diagnosed with incidental COVID-19, and underwent surgery, did not have a worse outcome due to the COVID-19 virus compared to their counterparts who did not have the virus.
Methods: This retrospective study included surgical patients (COVID-19 incidentals and COVID-19 negatives) who were admitted to the surgical intensive care unit (SICU) at Tygerberg Academic Hospital between 1 May 2020 and 31 December 2021.

Despite being designated as "noncarcinogenic" human papillomavirus (HPV) types, mono-infection with HPV6 or HPV11 has been found in squamous cell carcinomas (SCCs) at specific sites, including the larynx, penis, anus, and rarely, the lower female genital tract. The association between clinicopathologic features, viral status, and the carcinogenic mechanisms related to these low-risk HPVs remains unclear. The current study characterizes a series of low-risk HPV6 and HPV11-associated SCCs of the uterine cervix (6 cases) and vulva (2 cases).

Background: During the SARS-CoV-2 pandemic, dominant viral variants were repeatedly replaced by new variants with altered properties, frequently changing the dynamics of the infection event, as well as the effectiveness of vaccines and therapeutics. SARS-CoV-2 variant monitoring by whole genome sequencing was established at the University Medical Center Mainz, Germany to support patient management during the pandemic.
Methods: SARS-CoV-2 RNA samples from the University Medical Center were analysed weekly with whole genome sequencing.

Background: Monkeypox (Mpox) is a re-emerging zoonotic disease with limited therapeutic options, necessitating the exploration of novel antiviral agents. (turmeric) is a widely used medicinal plant known for its antioxidant and anti-inflammatory properties, primarily attributed to its bioactive curcuminoids.
Aim: This study aimed to evaluate the therapeutic potential of aqueous extract (CAE) against monkeypox through phytochemical characterization, biological assays, and computational analyses.

Background: SIREN is a healthcare worker cohort study aiming to determine COVID-19 incidence, duration of immunity and vaccine effectiveness across 135 NHS organisations in four UK nations. Conducting an intensive prospective cohort study during a pandemic was challenging. We designed an evolving retention programme, informed by emerging evidence on best practice.
