Among the second batch of First Phase Gravidtrap Indexes covering nine survey areas and Area Gravidtrap Indexes covering nine survey areas in November, all were below 10 per cent.

The FEHD has so far released two batches of gravidtrap indexes for Aedes albopictus in November 2025, covering 24 survey areas. Among these 24 survey areas, 16 recorded a decrease or remained unchanged in the individual gravidtrap index as compared to the Area Gravidtrap Index last month, i.e. October 2025, representing that the areas' mosquito infestation improved or maintained a low level. Eight other areas recorded a slight increase, but the indexes were lower than 10 per cent.

Public participation is crucial to the effective control of mosquito problems. The FEHD appeals to members of the public to continue to work together in strengthening personal mosquito control measures, including:

tidy up their premises and check for any accumulation of water inside thepremises;

remove all unnecessary water collections and eliminate the sources;

check household items (those placed in outdoor and open areas in particular), such as refuse containers, vases, air conditioner drip trays, and laundry racks to prevent stagnant water;

change the water in flower vases and saucers of potted plants at least once every seven days;

properly cover all containers that hold water to prevent mosquitoes from accessing the water; and

properly dispose of articles that can contain water, such as empty lunch boxes and cans.

Starting in August this year, following the completion of the surveillance of individual survey areas, and once the latest gravidtrap index and the density index are available, the FEHD is disseminating the relevant information through press releases, its website, and social media. It aims to allow members of the public to quickly grasp the mosquito infestation situation and strengthen mosquito control efforts, thereby reducing the risk of chikungunya fever (CF) transmission.

Following the recommendations from the World Health Organization and taking into account the local situation in Hong Kong, the FEHD sets up gravidtraps in districts where mosquito-borne diseases have been recorded in the past, as well as in densely populated places such as housing estates, hospitals and schools to monitor the breeding and distribution of Aedes albopictus mosquitoes, which can transmit CF and dengue fever. At present, the FEHD has set up gravidtraps in 64 survey areas of the community. During the two weeks of surveillance, the FEHD will collect the gravidtraps once a week. After the first week of surveillance, the FEHD will immediately examine the glue boards inside the retrieved gravidtraps for the presence of adult Aedine mosquitoes to compile the Gravidtrap Index (First Phase) and Density Index (First Phase). At the end of the second week of surveillance, the FEHD will instantly check the glue boards for the presence of adult Aedine mosquitoes. Data from the two weeks of surveillance will be combined to obtain the Area Gravidtrap Index and the Area Density Index. The gravidtrap and density indexes for Aedes albopictus in different survey areas as well as information on mosquito prevention and control measures are available on the department's webpage (www.fehd.gov.hk/english/pestcontrol/dengue_fever/Dengue_Fever_Gravidtrap_Index_Update.html#).

Speech by FS at CUHK EMBA Annual Conference

Following is the speech by the Financial Secretary, Mr Paul Chan, at the CUHK EMBA Annual Conference today (May 9):

Professor Dennis Lo (Vice-Chancellor and President, the Chinese University of Hong Kong (CUHK)), Professor Lin Zhou (Dean, CUHK Business School), Macy (Chairperson of Organizing Committee, Ms Macy Chan), Michael (Chairperson of Organizing Committee, Mr Michael Chan), CUHK EMBA alumni and students, business leaders, distinguished guests and friends,

Good evening.

Addressing a room full of Executive MBA students and graduates is both an honour and a privilege. There is a particular kind of ambition in this room — one that is not content with success alone, but driven to understand it more deeply, in the belief that better ideas lead to greater impact.

That kind of commitment — to learning, to growth, to asking harder questions — is precisely what today's conversation is about.

The theme of this conference, which focuses on innovation and agile leadership, could not be more timely. Most of us here have lived through the Internet age and the smartphone revolution, which made communication faster and more seamless than anyone had imagined.

Today, the rise of AI places us at a more fundamental tipping point. Technology is not merely changing the answers — it is redefining the questions themselves.

Consider what is already within reach. An AI assistant can learn your preferences, curate a personalised shortlist, and simply ask for your confirmation. We should even ask whether the smartphone and the search engine will remain our primary gateways to the digital world, or whether something altogether new is already taking shape.

To draw an analogy, the power of technology does not lie in drawing the old map with greater precision. It lies in revealing how much of that map remains uncharted — and in showing us that entirely new maps, with new co-ordinates, are being drawn.

This redefinition is unfolding across three dimensions simultaneously.

First, the redefinition of products. Products are no longer discrete, standalone objects. A smart car is a vehicle, but also a mobile platform for data. An insurance policy can be a contract, but equally a dynamic reflection of health data. Innovation today is born from cross-sector convergence and continuous evolution.

Second, the redefinition of services. Services are no longer delivered solely by enterprises. They emerge from collaborative networks of people and AI. But the more profound shift is in what customers now expect. In the past, good service meant reaching the right person quickly. Today, customers expect a solution that anticipates their needs before articulating them. This requires a new architecture of service delivery: human and machine, with AI handling the scale, the speed, and the personalisation that no human team alone could sustain.

Third, and most importantly, the redefinition of business models. In the past, we sought optimal solutions within established frameworks — when demand rose, we expanded capacity; when service needs grew, we opened more branches. Technology invites us to break out of those frameworks entirely. Intelligent manufacturing means that "economies of scale" is no longer the only answer; flexible supply chains have made customised, on-demand production the new normal.

These three redefinitions are opening a commercial frontier unlike anything we have seen before. But if the benefits of technology accrue only to a small circle, its power remains fundamentally constrained. This brings me to the second message I want to leave with you today: inclusivity.

Inclusivity is not charity. Yet it is the smartest business strategy available. The unmet needs of the broader public represent the largest and most underserved market opportunity in existence. When you make quality healthcare, education and financial services accessible and affordable to ordinary residents, you are not serving a group in need of handouts — you are unlocking a vast market that traditional business models have consistently overlooked.

Hong Kong has a distinctive role to play here. We can be a co-architect of standards, a hub for capital, and a bridge between innovation and real-world deployment — from clinical validation of smart healthcare, to green technology financing, to regulatory sandboxes for fintech. Our contribution draws not only on institutional strengths and international networks, but on our genuine commitment to broad-based participation.

Yet inclusive products and services are only the first step. The deeper dimension is empowerment.

History reminds us that the dividends of technological revolution need to be actively guided to reach the many. In the age of steam, and again in the Internet era, early gains concentrated among capital owners and top-tier talent. But today we have the opportunity to write a different story. AI, as an amplifier of human capability, is already enabling what was previously unimaginable: a solo entrepreneur, with the right tools and the right vision, can build a unicorn.

In other words, the unit of competitive advantage is shifting — from the size of your team to the skill with which you orchestrate your tools.

Our mission should be to make that shift available to everyone. To turn individual readiness into collective prosperity, and to ensure that the productivity gains of AI flow broadly across the society.

This is precisely why, in this year's Budget, I placed such emphasis on the "AI Training for All" initiative.

We are not trying to turn everyone into an engineer. We are ensuring that workers, managers, SME (small and medium-sized enterprise) owners, and ordinary residents become capable collaborators with AI: people who can access it, use it effectively, and put it to work as their assistant.

That may sound ambitious, but consider this: if AI can one day be as intuitive as the smartphone, then mass adoption is not difficult to imagine at all. Just as computers once migrated from specialist facilities into offices and homes, AI will find its way into everyone's daily work and life.

For business leaders, it may be tempting to think of AI as "digital employee" that can replace existing workers. But think of a different framing: equipping your workforce with powerful digital assistants can achieve productivity gains, while also freeing your people to do what humans do best — create, imagine and innovate.

Companies that take those extra steps, and think those extra moves ahead, will find that an empowered workforce is also a more innovative one.

All in all, the power of technology must ultimately be measured by its contribution to inclusive growth. And inclusive growth, in the end, depends on, yes, commercial acumen — but also empathy, compassion, and the conviction that a rising tide should lift all boats. I can see that those qualities live in this room.

I will close with this thought. Someone once joked that economists know the price of everything and the value of nothing. With AI, let us never fall into the same trap — in our race to price every efficiency gain, let us not lose sight of the deeper value we are trying to create: a society where the fruits of innovation are broadly shared, and where technology lifts not just the fortunate few, but everyone willing to reach for it.

So here is my ask: let us grow the pie together. And make sure we cut it well.

Thank you very much.
