A university study has identified Hong Kong and the United Arab Emirates as strategic locations for a global early warning system to detect emerging pandemics. By implementing targeted viral surveillance of transit passengers at these two major aviation hubs, researchers found that the international community could accelerate the detection of new viral variants by approximately three days.
The study, led by Professor Leo Poon Lit-man, chair of public health virology, highlights the effectiveness of monitoring high-traffic transit points to track the spread of pathogens. By focusing surveillance efforts on these key international gateways, health authorities could potentially gain a critical head start in identifying and responding to future outbreaks before they become widespread.
