⚠️BREAKING—Singapore 🇸🇬 returning to lockdown mode for one month as #COVID19 cases rise, many #B16172 variants. Indoor dining suspended immediately. Travel bubble with HK🇭🇰 now unlikely. 31% of Singaporeans have >=1 shot, 22% fully vaccinated. Still surge.
bloomberg.com/news/articles/…
2) 🇸🇬 is returning to the lockdown-like conditions it last imposed a year ago, banning dining-in and limiting gatherings to two people, as a rising number of untraceable virus infections pressures one of the most successful places in the world at Covid containment.

➡️YET STILL!
3) “A pattern of local unlinked community cases has emerged and is persisting,” the statement said. “We need to act decisively to contain these risks as any one leak could result in an uncontrolled resurgence of cases.”
4) “new cases in the community has increased to 71 in the past week from 48 in the week before, while the number of unlinked infections— the most concerning to officials as they signal undetected spread in the community—has risen to 15 in the past week from 7 in the week before.
5) “While the numbers are far smaller than ongoing outbreaks in countries like the U.S. that are charging ahead with opening up, the flareup is a major setback by Singapore standards, as it is one of handful of “Covid havens” that had previously nearly eliminated it domestically.
6) “The return to near-lockdown in Singapore puts in doubt high-profile global initiatives meant to showcase its control of the virus. An long-gestating air travel bubble with Hong Kong, set to start May 26, is now unlikely to go ahead on schedule.”
7) This is why I’m not happy about yesterday’s CDC guidelines to lift mask rules for vaccinated people, which in the US we cannot even verify directly.
8) Singapore having a sizeable outbreak at its airport too. Multiple #B16172 variants detected and 11 vaccine breakthrus
9) For those asking what kind of vaccines Singapore used… Pfizer and Moderna, the two highest efficacy ones. Yet still some breakthroughs. We just need to vaccinate much more than 20-40%.
10) despite Singapore having decent pace in vaccinations, albeit slightly behind, it knows that vaccine only strategy isn’t enough.
11) here is some concern about the #B16172 variant from India…. See thread 🧵
13) A lot of variants in the Singapore outbreak. Singapore imported all its cases and then let it transmit in the community until too late.
14) Now Taiwan is also following Singapore in having somehow a new sudden outbreak.
15) the alarming news bulletin from UK 🇬🇧 SAGE govt report on the #B16172. It’s quite fast.

Doctors treating patients in India 🇮🇳 have marked a distinct trend during the 2nd wave—#COVID19 now appears to be impacting children more severely. Children and adolescents are now showing more obvious symptoms such as prolonged fever and gastroenteritis.🧵hindustantimes.com/india-news/in-… Image
2) During the first wave, most children remained asymptomatic, and a large number of them went untested because of that,” said paediatrician Dr. Bakul Parekh. “We tested children only when someone in the family had a history of Covid-19.”
3) Over the last fortnight, Parekh, who runs a children’s hospital in Ghatkopar, has admitted six children between 1 and 7 years old to the hospital -- three with severe gastrointestinal infections and fever, and others with breathlessness and fever.

BREAKING—Taipei, Taiwan 🇹🇼 has raised its local #COVID19 crisis rating to Level 3 alert for the first time, after 180 domestic transmission cases. Masks will now be required indoors & outdoors. 🇹🇼 has 23 mil people—first time exceeding single digit average daily cases in a year. Image
2) Under the CECC's four-tier alert system, a Level 3 alert means people are now required to wear masks at all times when they leave their homes, indoor gatherings of more than five people are not allowed, and outdoor gatherings are limited to 10 people.

focustaiwan.tw/society/202105…

KEEP WEARING THE MASK—We card-carrying epidemiologists (with formal doctorate in epidemiology) know what we are talking about. Vast majority of 700+ epidemiologists surveyed says we would keep wearing masks for 1 year or longer. #COVID19 #MaskUp

nytimes.com/2021/05/13/ups… ImageImage
2) “When federal health officials said on Thursday that fully vaccinated Americans no longer needed to wear masks in most places, it came as a surprise to many people in public health. It also was a stark contrast with the views of a large majority of epidemiologists surveyed.
3) “In the informal survey (of professional epidemiologists), 80 percent said they thought Americans would need to wear masks in public indoor places for at least another year. Just 5 percent said people would no longer need to wear masks indoors by this summer.

96% of critical care beds in Osaka Japan 🇯🇵 are full. Hospitals “overwhelmed”.

Olympics in 70 days? 🤷🏻‍♂️ #COVID19

theguardian.com/world/2021/may…
2) Osaka, along with Tokyo and two other prefectures, will remain under a state of emergency called in late April until at least the end of this month, and another three regions are due to join them from Sunday, Japanese media reported on Friday.

3) the vaccine rollout for older people and other at-risk groups is only just picking up speed. About 3% of the population of 126 million have been inoculated so far, amid reports of problems with the vaccination booking system, queue-jumping by local politicians & businesspeople

ONLY VACCINES?—What if we dropped all masks/mitigation, and only rely on vaccines? Well, with 70% fully vaccinated, even if vaccines have 97% efficacy against all transmission (they don’t)—we can only stop Wuhan 1.0 slower strain. Forget #B117/#P1/#B1617.🧵

(HT @GosiaGasperoPhD)
2) However, the math to stop #COVID19 completely changes if we add masks and other public health motivations. Even with lower transmission efficacy vaccines, even with more faster contagious variants—when combined together, vaccines + masks + mitigation can hold back surge!
3) the main leakage with the vaccine only approach is that asymptomatics keep spreading even if vaccines work for severe #COVID19 disease. And it will leak to the vulnerable.
