The study results would inform the global research agenda on clinical management and the development of intervention strategies aiming at reducing the burden posed by COVID-19 and SARS-CoV-2 infections.


The on-going nation-wide outbreak caused by the Delta variant in a relatively naïve population in Vietnam necessitates a multidisciplinary research approach to better understand the clinical futures, virology, pathophysiology and associated host genetic factors of the infections, especially determinants of severe diseases. These data are critical to informing the development of appropriate intervention strategies, thereby improving clinical outcomes and mitigating the impacts of the COVID-19 pandemic.


1. To describe the clinical features and associated laboratory findings in children and adults with SARS-CoV-2 infection
2. To understand the circulation and evolution of SARS-CoV-2 in Viet Nam
3. To describe and compare SARS-CoV-2 viral loads in children and adults
4. To gain insights into the immune responses in children and adults infected with SARS-CoV-2 infections
5. To identify potential factors (including host-genetic markers) that are associated with poor clinical outcome of SARS-CoV-2 infection.
