Data not anecdote, please

Our new health minister on his blog yesterday:

Writing in his official blog, [new health minister Professor Lo Chung-mau] also warned that the coronavirus was not like the “common flu”, citing a case involving an 18-month-old child in Singapore who had died of encephalitis several days after contracting Covid-19.

“What makes me even sadder is that the toddler’s three-year-old sibling seemed to understand that his brother would never come back, losing his appetite and sitting quietly all day, dazed,” he said.

A couple of points: 

1. This is an anecdote. It's a very powerful picture of a tragedy, it’s very compelling, people will remember it.  But...

2. It’s not data. It’s not representative. Children can die of many diseases, including Covid. It’s always tragic, but not always -- -as here -- representative. The number of children who die of Covid is tiny. In Hong Kong, to date, we have 12,940 children under 3 who have tested positive for Covid and of those ONE has died. (I happen to know the case, and it was a serious comorbidity). That’s less than one in ten thousand. It may be worth vaccinating against that risk; or it may not. We don’t yet have the data. Because....

3. AFAIK: there has been no large-scale testing of any of the vaccines for the under 3s. The UK is not recommending vaccine jabs for them. 

So.... I think Professor Lo, our new health minister, is irresponsible in retailing an anecdote like this one. Because it is so vivid and persuasive, it will have people thinking that children are at serious risk of dying from Covid. Which they are not. According to the science

he said this last week, and the week before that.  When are they actually going to come up with a plan rather than talking about making a plan?
1. STOP THE FLIGHT SUSPENSIONS. 2. Stop the quarantine. 3. Stop locking up healthy people like criminals. 3. Stop putting people with a sniffle in hospital. 4. Stop counting "cases" as if it means something. 5. START acting as if you truly mean to fix the Hong Kong.
"Inconvenience" is an incredibly soft word to describe the feelings of travellers: Finding a hotel and a flight, rebooking everything because of a flight ban, waiting at the airport, the transportation to quarantine hotel, the multiple PCR tests,... Everything is an unjustified nightmare and an insult
