Background: Since the beginning of the pandemic, contact tracing has been one of the most relevant issues to understand SARS-CoV-2 transmission dynamics and, in this context, the analysis of quasispecies may turn out to be a useful tool for outbreak investigations. Analysis of the intra-host single nucleotide variants (iSNVs) found in the nsp2, ORF3, and ORF7 genes of SARS-CoV-2 was conducted in order to correctly identify virus transmission chain among patients hospitalized in Brescia Civic Hospital.
Methods: During the period between August and October 2023, 13 nasopharyngeal specimens, collected from patients admitted to Brescia Civic Hospital, were tested for SARS-CoV-2 positivity and molecularly characterized.
Article Synopsis
- The COVID-19 pandemic led to the use of non-pharmaceutical interventions (NPIs) that reduced the spread of not only SARS-CoV-2 but also various other respiratory viruses like Influenza and Rhinovirus.
- A study analyzed respiratory virus samples from June 2021 to March 2023 to understand the effects of lifting NPIs post-pandemic compared to the pandemic period.
- Findings indicated that NPIs were effective in controlling multiple respiratory viruses, with Rhinoviruses and Enteroviruses being the most prevalent, often detected in co-infection cases, highlighting the need for robust molecular screening for better surveillance and prevention.
