How can airlines claim flights are safe when there is no record of who was infected on board.
"There is a new record for the number of coronavirus infections traced back to a single commercial airline flight. A whopping 47 passengers..from New Delhi to Hong Kong April 4 have since tested positive for Covid-19. That number represents 25% of the 188 passengers on board.

1/
"All passengers..had tested negative for the virus within 72 hours prior to departure, in keeping with Hong Kong’s travel requirements. Yet 25 travelers tested positive immediately after landing in Hong Kong, and a further 22 cases were discovered on day 12.

2/
"While this happened on the other side of the world, Americans should not assume it could never happen here — or that it hasn’t already happened. But we may never know.

3/
"The United States has never implemented a contact tracing program for air travelers — even more than a year into the pandemic, and even as new variants pop up around the world.

4/
"One likely reason is that the airline industry has pushed back on government-mandated restrictions, while issuing its own research and implementing protocols it claims prove that flying is a low-risk activity.

5/
"At the same time, multiple independent studies — from UK, New Zealand, Ireland, Vietnam and other countries — found Covid-19 can indeed spread on long-haul flights. In each case, researchers traced Covid-19 outbreaks back to one or more individuals who had recently flown...

Canada’s Crazy Pandemic Response
"As the third wave built and now may drown us, our leaders keep blathering about ‘balance.’

"If you want to know how crazy the COVID-19 crisis has become in Canada, just listen for a moment..

@TheTyee thetyee.ca/Analysis/2021/…
"to Quebec Premier Francois Legault.

“We’ve had no choice but to lock down, reopen, lock down, reopen,” protested the premier last week as he acknowledged how fed up people are with Canada’s disastrous yo-yo approach to COVID-19.

2/
“The idea is to try to find a balance,” added Legault. “When we lock down, it’s to protect people’s physical health; when we reopen, it’s to help their mental health.”

Strongly suppress where it is, protect where it isn't, contract geographically.

More clarity on breakthrough infections (people who get infected after having been vaccinated) is available. CDC data shows that of these breakthrough infections, 7% were known to be hospitalized and 1% died.

1/

In other words, according to this data, when someone does get a breakthrough infection, they have a similar chance of death as someone who got infected without being vaccinated. (Of course, vaccination does a lot to prevent infection in the first place.)

2/
The effect of variants? "Some of the breakthrough infections are thought to stem from certain strains of the virus that may be more resistant to vaccines, experts say. They also say some highly contagious variants may pose a greater risk of reinfection from other variants"

With the growing power of mass vaccination to reduce transmission, but with vaccine hesitancy and the threat of vaccine evading variants, we should consider mix and match elimination strategies:

1/
What strategies might work combining mass vaccination, mass testing, mass high quality masking, and stay at home restrictions, to achieve local elimination?

2/
Green zones continue to be the way to open up without restrictions, avoiding outbreaks of breakthrough variants. What level of border control or travel restrictions are needed depends on other ongoing precautions and vigilance.
