Studies about the evolution of SARS-CoV-2 lineages in different backgrounds such as naive populations are still scarce, especially from South America. This work aimed to study the introduction and diversification pattern of SARS-CoV-2 during the first year of the COVID-19 pandemic in the Northwestern Argentina (NWA) region and to analyze the evolutionary dynamics of the main lineages found. In this study, we analyzed a total of 260 SARS-CoV-2 whole-genome sequences from Argentina, belonging to the Provinces of Jujuy, Salta, and Tucumán, from March 31st, 2020, to May 22nd, 2021, which covered the full first wave and the early second wave of the COVID-19 pandemic in Argentina.

- The study investigated the prevalence of Human bocavirus (HBoV) in pediatric patients hospitalized for acute respiratory tract infections (ARTI) in Santa Fe and Tucuman, Argentina.
- HBoV was found in 7% of samples, with a higher occurrence in children under 2 years old and during the spring and summer months.
- The presence of other respiratory viruses was also noted in 22% of samples positive for HBoV, suggesting a need for further research to understand the nature of these infections.
Introduction: While there is much information about the burden of influenza A(H1N1)pdm09 in North America, little data exist on its burden in South America.
Methods: During April to December 2009, we actively searched for persons with severe acute respiratory infection and influenza-like illness (ILI) in three sentinel cities. A proportion of case-patients provided swabs for influenza testing.
