Hi all, we submitted the #COVIDー19 genome sequence from the viral strain linked to the #GrandPrincess cruise ship off coast of San Francisco to #GISAID. Phylogenetic analysis shows that it clusters with the outbreak clade circulating in Washington State. @UCSF #coronavirus
Please note that this finding does NOT prove that the virus was transmitted from Washington State to California, or vice-versa. There are other scenarios possible, such as separate introductions from outside of the US, that are compatible with the phylogenetic grouping.

Six new #COVIDー19 in bc
2 related to Iran travel
2 in 60s from princess cruise 11-21 feb trip - Fraser health region - stable but in hosp for observation
More may test positive who were on that cruise
2 most concerning - residents of Lynn valley care centre
#bcpoli
Dr Bonnie Henry says the two positive tests in the care home leading to large investigation into residents and workers and what contact they’ve had.
And there are restrictions on that facility now for who is in and out.
#bcpoli #COVIDー19
Four recovered
The icu patient stable
2 I
All others in isolation
Also those with contact in isolation
“We are in an extraordinary situation” - Henry says - if you are sick stay home, keep your kids home.
But know that not everyone who is sick has #COVIDー19

THREAD: #COVID-19 lays bare the ways in which mass incarceration endangers public health for all of us.
A jail or prison is a closed-circuit environment like a cruise ship, but where many people arrived with communicable illness that makes them vulnerable, buildings are crumbling, rats and roaches, people crowded on top of one another with little sanitation.
This is not to mention the people who work in jails and prisons, who are in danger of becoming ill and spreading infection among incarcerated people and within their home communities.

I've been talking with passengers on the #GrandPrincess cruise ship that's being held off the coast. They tell me helicopters just dropped off #coronavirus test kits.
Passengers tell me about 100 people who have been identified will be tested

They says those include:

-Passengers who were on the first cruise to Mexico,
-Crew who've been in contact with them
-Anyone who went to onboard medical center w flu-like symptoms or respiratory issues
Passengers tell me everyone else, not being tested, is free to roam on the ship.
They tell me dining room, decks, etc. are currently open.

Two helicopters approaching the #GrandPrincess with #coronavirus test kits. Again, my parents are on board (as well as many other parents and siblings and children). Please pray for them. @PrincessCruises @GavinNewsom @KTVU #COVID19
The helicopters have now departed. I assume all those who need testing will have samples drawn, after which the samples will be delivered to Richmond where the four-hour-long testing procedure commences.
I'll post additional updates here. Again, thanks to the hardworking reporters covering this story.
- No strict order to return to rooms but it's suggested
- Passengers are told to maintain six feet of distance from one another
- Suggested that diners space themselves by a seat

🚨BREAKING: #GrandPrincess cruise ship appears to be a new #coronavirus “hot zone.”

@thespybrief
thedailybeast.com/grand-princess…
A former passenger on the #GrandPrincess DIED today in #California after getting infected with #coronavirus onboard the ship.

Now, 21 NEW passengers on the same ship report having #COVID19 symptoms.😳

#CoronavirusOutbreak
The #GrandPrincess planned to dock in San Francisco, but Gov @GavinNewsom delayed it, as 21 passengers/crew developed #COVID19 symptoms.

The ship has 2,600 guests + 1,150 crew.

They *must* be evacuated NOW under quarantine.

The longer they remain, the MORE infected.🚨

California is declaring a state of emergency in light of its 1st death due to coronavirus in Placer County AND b/c of the revelation that person was likely exposed during a Feb. 11-21 cruise on a Princess cruise ship that departed from San Francisco to Mexico, Gov. Newsom says
Newsom said "by one estimate over 50% of the passengers ... roughly 2,500 passengers that does not include the crew are Californians."

Officials are working to contact all of the passengers from that cruise.
On top of that, Newsom said the same ship is coming back from a second cruise to Hawaii and is being held off the coast of SF so that they can fly COVID-19 test kits to the ship and sent those back to the state.

He said "a number of" passengers & crew have developed symptoms.
