Pandemic control is a classic example of what game theorists call a coordination game. It’s a game where the highest payout can only be achieved by players agreeing to the same plan of action. In a multiplayer game, if most players believe one plan to be the best plan and act accordingly, the payout changes for the remaining players and they become overwhelmingly incentivised to join the rest of the players.
When it comes to pandemic control, the optimal strategy for each player is such that if most countries in the world are adopting a “zero Covid” policy, it is rational for a country to adopt the same strategy. This way, the virus can collectively be eradicated and everyone wins.
However, if most of the countries in the world decide that “living with the virus” is the optimal strategy and believe the best defence against the virus is herd immunity, then the payout for the countries who hold on to zero-Covid becomes dramatically different. Because virus eradication requires coordination from all countries, when most countries have ruled out that possibility, eradication becomes impossible. Covid-zero becomes a strategy with only cost but no upside.
The optimal strategy in this case is clearly to join the rest of the world and start to live with Covid-19 and develop herd immunity. I hope our leaders can see the maths and understand that, whatever short-term political calculations there may be, this is the inevitable conclusion of logical deduction that no one can escape.
Huan Liu, Sham Tseng


Lawmakers owe more than blind support
I refer to your report on March 22 of the pro-establishment legislator Junius Ho Kwan-yiu considering a no-confidence motion against Chief Executive Carrie Lam Cheng Yuet-ngor for her “flip-flopping policy on universal testing”. It further mentioned that “many members in the bloc shared Ho’s feelings of ‘betrayal’ by Lam, who applied a brake on mass testing after asking them to publicly support such an exercise”.
If this is the reason for Ho to put forward the motion, it would seem pro-establishment lawmakers were blindly supporting the chief executive without any critical assessment of the feasibility of mass testing, the resources involved and the capacity of our healthcare system.
In early March, Hongkongers were panic buying food and medicine in case the city went into lockdown during mass testing. Instead of listening to our medical experts who advised against mass testing, the administration kept the option on the table.
I cannot see why legislators who supported the chief executive on mass testing should feel angry she has now suspended the scheme, which was actually a sensible decision. The Hong Kong government was slow in responding to the fifth wave, the biggest Covid-19 outbreak in Hong Kong in the past two years. Limited resources should be focused on mitigation since Hong Kong’s capability and capacity are stretched to the breaking point.
The pro-establishment camp has many highly educated professionals and intelligent people capable of critical and independent thinking. Perhaps they should, after making a critical analysis of the pandemic situation, give constructive advice to the chief executive instead of doing what they think will get them the greatest political mileage. After all, they are legislators whose job is to make laws for people in Hong Kong and monitor the government’s performance.
Yin Ling Lee, To Kwa Wan
Lam should listen to science, not mainland netizens
I disagree with your editorial that “packed beaches” are “no place for latest wave” (March 17). There is no evidence that Covid-19 is easily infectious in outdoor situations, so people will be more secure at beaches than at indoor locations in our congested city.
A real benefit of going to the beach is that one receives a necessary dose of vitamin D, which strengthens our immune system and is a key ingredient in fighting Covid-19. A problem for our elderly in care homes is that they can be deficient in vitamin D and thus their immune systems are impaired.
Chief Executive Carrie Lam Cheng Yuet-gnor is Hong Kong’s leader and should not be so easily swayed by the criticisms of mainland netizens who have little understanding of the science on the Omicron variant or Hong Kong’s particular situation.
