📍REJECTING THE CDC ISOLATION RULE—Taiwan🇹🇼’s Central Epidemic Command announced it will not follow @CDCgov guidance on shortened 5-day isolation because #Omicron cases have been found to be infectious *up to 12 days* after positive. @CDCDirector is wrong.

2) “He warned that if a cluster infection appears in a quarantine center or epidemic prevention hotel and is not detected in time, it could quickly spread into the community—& would be a daunting task to contain, and the risk to society would increase substantially”

3) “Regarding the U.S. CDC's recommendation to shorten quarantines from 10 to five days, Lo said 23 imported #Omicron cases have been tracked for more than five days—of these cases, 17 had a Ct level of 30+, the standard to be released from quarantine.” (🇹🇼 reqs PCR for release!)

4) “Lo added that these cases did not reach this Ct level **until at least eight days** after they had fallen ill or tested positive. He said the longest it has taken for an Omicron case to reach the standard for release is 12 days after diagnosis”! 👀

5) On top of CDC’s poor 5 day isolation exit rule without any testing — the @CDCDirector’s issued rules are extremely vague & dangerously muddy — you technically only need to have “resolving” (improving) symptoms, not actually zero. Plus, we know asymptomatic can still spread!

6) California is also rejecting the @CDCDirector’s poor no-testing isolation exit rules. California, while allowing an earlier exit— will require one negative test to do so. This is better than CDC’s but not as good as UK’s which requires 2 negative tests.

7) people will definitely abuse that vagueness to be blasé and ignore isolation. Businesses will abuse it too— to the detriment of public health. Meanwhile here is how UK rightfully sets clear cut isolation guidelines with 2 negative tests on top! 👇

8) CDC needs to work hard to earn its mojo back… because last week’s unscientific “no test needed for early isolation exit on day 5” has harmed its reputation. @CDCDirector needs to recant!

9) This isn’t my cartoon… but is this 👇 how you want to be remembered @CDCDirector Walensky, as = Lord Farquaad from Shrek? Because the history books will remember how you gutted the @CDCgov in just one week. These memes will be how people remember you unless you recant.

10) CDC honestly has to shape up — its own policies are self contradicting on N95 respirators — it says people should wear them for wildfire smoke aerosols but not for coronavirus aerosols??? Can’t make this up! 👇 we need N95 for all— yet CDC is holding out on this!

11) @CDCgov still has not updated any guidance on the shortened isolation protocol without any testing exit. They need to reconsider and act now before more lives are endangered… @michaelmina_lab tells it like it is 👇
