Background: Admission to shared hospital rooms are a risk factor of healthcare-associated (HA) SARS-CoV-2. Quantifying the impact of engineering controls such as ventilation and filtration is essential to informing resource utilization and infection prevention guidelines.
Methods: Multicenter test-negative study of patients exposed to SARS-CoV-2 in shared rooms across five hospitals between January and October, 2022.

COVID-19 variants continue to infect thousands of people even though the end of the pandemic was announced on May 11, 2023. Nextstrain CoVariants (CoVariants) genomic databases provide detailed information about more than 31 variants of COVID-19 viruses that have been identified through genomic sequencing, showing the mutations they carry. Mutated viruses may yield a negative result for a gene target using a PCR test that has a positive COVID-19 test result.

Objectives: This study compared the diagnostic accuracy of seven different commercial serological assays for COVID-19, using RT-PCR as the gold standard, through meta-analysis and indirect comparison.
Methods: Fifty-seven studies, published from November 2019 to June 2024, were included. The diagnostic performance of IgA, IgG, and total antibody assays for SARS-CoV-2 was assessed.

The global consumption of ready-to-eat (RTE) leafy green vegetables and berries has risen as consumers perceive them as safe and nutritious options. However, these foods have also been identified as sources of enteric viruses that infect the human gastrointestinal system, which are then excreted and can spread through the fecal-oral route. In Argentina, there is limited evidence on the detection of enteric viruses in food, and no legislation currently requires their detection in frozen or fresh produce intended for domestic consumption.

Background: Few studies have evaluated COVID-19 vaccine effectiveness (VE) in middle-income countries, particularly in eastern Europe. We aimed to estimate COVID-19 VE against SARS-CoV-2-confirmed hospitalizations and severe outcomes in Kosovo.
Methods: We conducted a test-negative case-control study using data from Kosovo's severe acute respiratory infection (SARI) sentinel surveillance system from January 2022 to June 2024.
