Global “flu-ization” of COVID-19: A perspective from Vietnam

Abstract

The widespread Omicron variant of SARS-CoV-2 has led to mild to asymptomatic manifestations, contributing to increased immunity among populations through vaccination and natural infection. However, a more relaxed attitude towards COVID-19 preventive behaviors is emerging globally, driven by "pandemic fatigue" – a normal response to a prolonged public health crisis. Additionally, there is a growing societal belief that SARS-CoV-2 is no more infectious than the common cold and no more virulent than influenza, leading to considerations of treating it as a seasonal viral outbreak.

During the first 18 months of the COVID-19 pandemic, Vietnam successfully controlled community transmission through rigorous adherence to contact tracing, isolation, testing, and physical distancing. In this Opinion article, we argue that, at least in a Vietnamese context, it is premature to consider COVID-19 as an endemic disease. Instead, we advocate for national and local measures to reinvigorate public support for continued, modified implementation of recommended protective interventions as a "future-proofing" response strategy. In the short to medium term, this approach offers the best practice preparedness for potential emergence of SARS-CoV-2 variants that may be more infectious and pathogenic than the current Omicron variant. Such measures not only help control COVID-19 but also safeguard against other infectious diseases with similar transmission routes that could threaten global public health in the future.
