India's cases and deaths continue to reach all-time highs.

Multiple reports on double mutant variant are inconsistent about its role. Limited sequencing being done. It may well be important. Reports of a tripple mutant variant surfacing.

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.

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..

"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.”

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/
nbcnewyork.com/news/coronavir…
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"
