Controlling COVID At Our Borders

To get to Net Zero, Andrew Nikiforuk writes, we have to tightly control our borders -- something we have not done:

On CBC’s The Current, Kelley Lee, Canada Research Chair in global health governance at Simon Fraser University, called the government’s response “reactive,” because the Indian variant had already arrived in Canada weeks ago.

“If there’s a gold standard of how a country can manage its borders to curb the spread of COVID-19, Ottawa hasn’t met it yet,” said Lee. “I’d say maybe Canada is like a bronze medal standard, possibly.”

Countries that shut down their borders early have controlled the virus:

The early border restrictors included Taiwan, Vietnam, China, Australia, New Zealand and Singapore, and none have experienced continuous lockdowns or even third waves.

By locking out the virus with effective border controls, these nations simultaneously protected public health and shielded their economies — a lesson Canada has not yet appreciated.

What is involved in controlling borders? Several things matter:

1. Timing matters. Border controls must be proactive, not reactive. Their goal is to prevent trouble. A nation can only do that by being prepared and acting quickly. Canada, for example, restricted non-essential travel in March 2020, but it wasn’t until early this year that mandatory testing and quarantine in government-managed hotels were set up. By then, variants from the U.K. and Brazil were already circulating widely in the community.

2. Take universal measures. Countries that have mostly stopped the virus at the border have applied screening, quarantines and testing to most, if not all travellers. “They didn’t have people slipping through the gaps,” said Piper.

3. A multi-layered approach secures the border. Given the pace and scale of globalization, novel pathogens will always show up at the doorstep, but they don’t have to invade the house if a layer of interventions secures the way.

Discouraging all non-essential travel is the first protection. Repeated testing and screening all travellers before, at and within the border forms the next layer of defence. The third consists of a well-enforced quarantine program that applies to most everyone.

Canada’s current three-day hotel quarantine is only for air travellers, followed by home quarantine. Much of Europe only applied restrictions haphazardly, and often had no testing or quarantine protocols until the second wave. In contrast, Australia and New Zealand have had a mandatory 14-day quarantine enforced by the police or the military since the beginning of the pandemic. Hong Kong insists on 21 days.

Vietnam, a nation of 97 million that borders China, stands out as singular example. Last March, it cancelled all inbound commercial flights. It then used a contact tracing system to track down cases, which never exceeded 110 a day. It also restricted travel within the country. Citizens that lived in a region with a high case rate weren’t allowed leave until cases had been suppressed in that region.

As a result, Vietnam achieved Zero COVID. It also recorded one of the highest economic growth rates in Asia last year. Limited air travel to low-risk neighbours — such as South Korea, Taiwan and Japan —has now resumed. Yet everyone arriving in Vietnam by air, sea or land must be tested and wait out a mandatory 14- to 21-day quarantine period.

It's clear that half measures don't work. It's not easy to be tough on a virus. But it's much easier to be tough at the beginning of a pandemic than it is later on in its run.
