Influenza A virus

Influenza infects tens of millions of people every year in the USA. Other than notable risk groups, such as children and the elderly, it is difficult to predict what subpopulations are at higher risk of infection. Viral challenge studies, where healthy human volunteers are inoculated with live influenza virus, provide a unique opportunity to study infection susceptibility.

A new era of flu surveillance has already started based on the genetic characterization and exploration of influenza virus evolution at whole-genome scale. Although this has been prioritized by national and international health authorities, the demanded technological transition to whole-genome sequencing (WGS)-based flu surveillance has been particularly delayed by the lack of bioinformatics infrastructures.

Avian influenza A viruses (AIVs) pose a threat to global health because of their sporadic zoonotic transmission and potential to cause pandemics. Genomic surveillance of AIVs has become a powerful, costeffective approach for studying virus transmission, evolution, and dissemination, and has the potential to inform outbreak control efforts and policies.

Although the microbiome is established as an important regulator of health and disease, the role of viruses that inhabit asymptomatic humans (collectively, the virome) is less defined. While we are still characterizing what constitutes a healthy or diseased virome, an exciting next step is to move beyond correlations and toward identification of specific viruses and their precise mechanisms of beneficial or harmful immunomodulation.

Respiratory syncytial virus (RSV) is one of the most interesting respiratory viruses in the world. This virus causes symptoms of illnesses like influenza and imposes a heavy burden on medical services and the economy. However, studies on RSV in Vietnam are limited, while most of the RSV research has primarily been done before 2015.
