This is nuts.
The #Suffolk County DA arrested two people including the owner of an Amityville pediatric office for selling fake Covid-19 vaccine cards. $220 for adults, $85 for children. Ledgers show they may have made $1.5 million dollars from this illegal scheme #NBC4NY

Surreal It is not everyday you see something you fought remarkably hard for for 2 years straight against massively entrenched thinking actually come to fruition & announced by@POTUS Many scientists, advocates, public health ppl have helped make these available for US public
Good news, folks: You can get free COVID-19 tests delivered right to your home. Head to COVIDtests.gov to get yours today.

Tonight, on @11thHour, I asked White House Press Secretary Jen Psaki if she regrets dismissing the idea of sending free Covid tests to every American, as she did last month, given that's basically what the administration is doing now. Watch her response:

This is beautiful. And very much worth listening to. I hope you do. Thank you @YoYo_Ma for this.
Some musical gratitude for all the healthcare workers who do the impossible every day. Simple Gifts, #songsofcomfort

Laboratory based PCR or Rapid tests Which is most appropriate for pandemic response? For public health it’s clear - #RapidTests are more effective Lab PCR is great for a doctor. But public health is not same as medicine By @RickABright @ZekeEmanuel washingtonpost.com/opinions/…

There are areas of public health where a PCR can / does have its advantages, particularly around surveillance. But for the average individual asking the question “Am I Infectious” “Do I Need to isolate” “Can I exit isolation?” the rapid test is almost always the better tool.

Symptoms ≠ infectiousness. You can be infectious without symptoms. For example, 30%-40% of cases are asymptomatic. The relationship btwn symptoms and infectiousness may vary. @michaelmina_lab notes with #Omicron symptom onset may happen before infectiousness.
Consider how you manage other illnesses that you do not get tested for like cold & flu. 🌡️If you have a fever, stay home until it has gone without medication. 🏃Resume regular activities when you feel you are able to manage them. Managing #COVID19 at home: ow.ly/olJj50HG1XI

people are surprised when I share this information with them--your symptoms are not indicative of your contagiousness--take the #rapidtests #COVID19
The test doesn’t care about symptoms Test ONLY cares about how much virus in a sample Symptoms just help decide when to stick a swab in your nose Cant believe that after 2 years of talking to @NPR & other media outlets more than I can count - this remains confused in headlines

A very nice study evaluating rapid antigen tests and PCR tests together.
Replying to @michaelmina_lab
Please check out our study on symptomatic LFT in clinical triage at the peak of the second wave. sciencedirect.com/science/ar… National impact study to follow soon.

Tip If you just became symptomatic & have 1 rapid test, Wait 24-36 hrs to use it so virus has a chance to grow to be detectable. Assume infectious in meantime. If you have 2, use 1 and if Neg, test again 24-36 hrs later, as above. If Positive, you have your answer immediately
Replying to @michaelmina_lab
What is important though is IF you are recently symptomatic AND you test negative, then definitely assume positive/infectious and test again in 24 hours, for example. But IF you test positive, no need to test again in 48 hours. You have the answer immediatley.

With all the news of vaccines & immunity, did you know measles infections destroy immunity and cause “Immune Amnesia”, increasing risk of all other infections Our research in ‘15 & ‘19 discovered this & the abbreviated story is written up nicely here: 1/ medicalrepublic.com.au/the-g…

This is common 1/15: Rapid Ag test Pos (7pm) 1/15: Drop off PCR swab (8pm) 1/15: Per Rapid test isolation started, contacts notified Further transmission events prevented 1/18 3 days later, PCR+ results finally returned Highlights importance of speed >> sensitivity
good god. in contrast, I tested AG+ 1/15 630-7p, dropped off a PCR 8p, got the lab receipt 930p, reported the AG+ on the OTC site, opened DC-CAN exposure notifications and activated. Next morning, friends had received notifications & then DC Health called. PCR+ returned 1/18.

Did You Know: When you swab your nose for a rapid test or a PCR test…. You do NOT want to go for the “snot and gooey” stuff. Nope, the virus lives in the cells lining your nose. You want the swab to rub against and “scrape” the cells of the nasal walls for the best sample.

That said - it’s ok if you do get the snot. Just isn’t the target. You want to collect the cells along the walls of her nasal passage.

This is constantly mixed up Test sensitivity is different than the sensitivity of a testing regimen 2 tests improves sens of a testing regimen But it doesn't mean that a singular test when used when infectious somehow needs a second test. It gives immediate actionable info.
