The emergence of Avian Influenza A(H9N2) in Vietnam requires an urgent call for vigilance and preparedness

Abstract

In response to the recent case of avian influenza A(H9N2) in Vietnam, it is vital to recognize the broader implications posed by avian viruses for public health. While the infected individual receives medical treatment, there is no evidence of human-to-human transmission further in Vietnam, easing immediate concerns. However, it is essential to consider such risks seriously and start precautionary measures beforehand due to their high frequency in bird populations, especially in Vietnam, their potential for zoonotic infections, their continual evolution, and the accumulation of mutations indicative of adaption to humans. However, this incident underscores the ongoing threat posed by avian influenza viruses, particularly in regions where they are endemic. Though H9N2 typically causes mild illness in humans, it has the potential to mutate and acquire the capability for sustained transmission, potentially leading to a pandemic. Strengthening surveillance, rapid response protocols, and promoting research to develop effective vaccines and antiviral drugs are crucial to prevent and control future outbreaks. By prioritizing these measures and bolstering global cooperation, we can better address the threats posed by avian influenza viruses like H9N2.
