In my job as a doctor I handle risk assessment regularly. I am also a parent to two kids. My daughter has been sent home to quarantine due to a confirmed case of COVID-19 in her class. I have some concerns as it pertains to Covid containment in schools. 1/ @tdsb@TOPublicHealth
High risk ppl (confirmed close contact w covid19) are in the SAME lineups as low risk ppl (runny nose).These lineups are LONG rn.If you don't believe me check out covidwaits.com. Social distancing is not always maintained. Glad these lines are mostly outdoors for now. 2/
Turnaround times are the SAME for high risk people vs. those with a runny nose, sometimes up to a week now. While I'd like to think everyone is self-isolating while they are waiting for results, in reality we know that there are a lot of people who will not, or cannot. 3/
How about schools? @tdsb screener does not prevent a healthy kid to go to school unless they have been in close contact w a CONFIRMED case. This means while a high risk kid (like mine) is waiting 6 days for test results, their sib can go to school. 4/ toronto.ca/wp-content/upl…
Since 30% of kids with COVID are asymptomatic, this means that the close sibling could be at risk of spreading COVID in their classroom while their high risk sibling awaits results. 5/
To get a handle on things ASAP, a coordinated effort should be made separate high risk tests and prioritize turnaround times/test options for those w high risk exposures. School screener should reflect current realities of testing to keep schools safe. 6/
Kids belong in school. Testing strategies should be coordinated with other proven measures: smaller class sizes, prioritizing outdoor spaces, hygiene measures, etc. I'm worried that given rising numbers- our schools won't be able to remain open safely through the fall. 7/ fin
If i am somehow mistaken about any of the facts listed here, I am happy to be corrected. I have tried my best to check protocol in test centres and school documents provided to me. @BogochIsaac@MalikaHSharma@TorontoIDDoc@DFisman@drmwarner

Genetic testing: there are so many tests to choose from! Karyotype, Microarray, Whole exome sequencing, they all sound the same. What's the difference? Read on and hopefully things will become clear... 🧵 #meded#tweetorial#medgen
First, let's remember that our DNA is found in really nice organized packages called chromosomes. Humans have 23 pair of chromosomes = 46 in total. Each chromosome has a short arm (p=petit) and a long arm (q=comes after p).
Genes are segments of DNA where each codes for a specific protein.
Genes are found along chromosomes in a predictable location and order. For example, the CFTR gene is found on the long arm of chromosome 7 in all humans.
RE: Race descriptors- While there is a place for them (like when discussing social determinants), it is not useful when stratifying cohorts as it is not binary nor a great surrogate for ancestry. We can do better!
ALSO: We need to stop using the term Caucasian.
I'm surprised that many ppl are not aware that the term Caucasian has supremacist roots. The term originated in the 1700s by a bunch of bros who believed the ppl in the "Caucus region" were the most beautiful ppl in the world, made in "God's image". sjsu.edu/people/carol.m…
Here is an excerpt that I hope will convince you to retire the term Caucasian from your lexicon.
Out of curiosity I attempted to book a COVID-19 test in Toronto today using the screening tool and followed ALL the links to the assessment centre sites at 7 pm. Shall we see what happened? Get your popcorn and Kleenex ready. covid19toronto.ca
Women's college. Alarm set for tomorrow at 5:45 am. If I'm not successful, at least I will see the sunrise.
University Health Network. Thoughts and prayers until I log on at 7:59 tomorrow, I guess?
As we may be headed into a long few months and bummed about everything-here is a thread of easy trails and gardens you can visit with kids around Toronto and vicinity for some nature therapy. We visited all of these:
Williamson park ravine. Entrance on Gerrard east of Coxwell. Short half km walk but sweet. Smalls creek runs through it.
Glen Stuart ravine. Off of Kingston rd, in upper beach area. Boardwalk and stairs is about 1.5 km. Easy. Very pretty.
Review on sickle cell trait and covid outcomes in Black popl’n by @UofT resident Dr.Osundiji. So important for us to study genetics in non-whites to better understand health outcomes in these populations. There is a caveat tho. ncbi.nlm.nih.gov/pmc/articles/P…
It is not a pass for the genetics community to ignore the well established non-genetic determinants of health outcomes in Black people. I’ll call this, “the other things”. blackhealthalliance.ca/home/social-de…
Genetics professionals need to be v. aware that our genetics enthusiasm is gobbled up by the laypublic and risks drowning out a commitment to fixing “the other things”. Genetic code cannot be fixed.
How can I make a decision re: my intentions when I have no guiding info, @tdsb? "To help with our planning, you will be receiving beginning Tue Aug 11 an automated School Messenger phone call from the TDSB asking for you to indicate your intentions for your child for Sept."
I know nothing about final class sizes or how they're going to do lunches or if there is more outdoor time. I know nothing about what is the protocol if my kid gets a fever or someone gets COVID in my kid's school. I don't even know what the actual hours of school will be?!
So a mere few weeks from the start of the school year, it seems that the only thing I really know for certain is that I will NOT be able to indicate my actual intentions about school to the automated school messenger tomorrow.
