The B1617 (Indian) variant of COVID19 was detected among the earliest reported cases of the Tan Tock Seng Hospital cluster. A look at the latest variants of the coronavirus in Singapore:
Singapore has discovered 29 local COVID-19 cases and 475 imported cases with overseas variants of the virus.
AdvertisementBesides the five cases at TTSH, one case with the B16172 variant is the Immigration and Checkpoints Authority (ICA) officer deployed at Changi Airport Terminal 1, and the other case is the cleaner deployed at a community care facility at Tuas South.
The viruses in each cluster are “phylogenetically distinct”, which suggests that the clusters are not linked to one another, said MOH.“Based on the early phylogenetic information available to us, the (TTSH) cluster is due to a viral variant, but the vaccine appears to have done relatively well against it,” said Assoc Prof Mak.

A total of 475 imported cases are detected with such variants. headtopics.com
Assoc Prof Mak said Singapore can also expect to see"more viral variants" identified over time, and that all necessary public health action has been taken to isolate and ring fence the cases.Education Minister Lawrence Wong, co-chair of the task force, said:"The new variant strains have higher attack rates, they are more infectious, they are causing larger clusters than before.”
"Due to the new variants, (the cases) are more infectious and larger clusters are forming," he added."As compared to say, months ago when we did have unlinked cases – but then you have one or two, and they would stop there, you wouldn't have such big clusters – this doesn't seem to be the case more recently with the ICA cluster, and the TTSH cluster," he said.
This is why tighter public health measures are required, he added.Assoc Prof Mak said that the “presence of viral variants of concern among our local cases affirms” Singapore’s vaccination strategy that prioritised healthcare workers and older Singaporeans.
Had Singapore not done so, the TTSH cluster would have been “significantly larger”, Assoc Prof Mak said.He added that out of the 40 reported cases in the TTSH cluster, eight cases who had been vaccinated were either asymptomatic or exhibited very mild symptoms, and none required oxygen therapy. headtopics.com
Of those who were not protected by vaccinations, seven of the 20 needed oxygen therapy.UPDATE ON TAN TOCK SENG HOSPITAL CLUSTERThe cluster linked to TTSH has continued to grow, with a total of 40 cases linked to it as of Tuesday, making it the largest active COVID-19 cluster currently.
Providing an update on the hospital cluster, Health Minister Gan Kim Yong said testing of all inpatients at the hospital has been completed.“The results have all been negative, other than those whom we have already announced. Yesterday, we completed a second round of testing of these inpatients, and the results are pending," he added.
“Some of them may be incubating, and may become positive in the days ahead, and we will continue to monitor them."Testing of all 12,000 staff members on campus is also in progress. So far, about 10,000 employees have completed testing."We will give an update, as and when the results are out. Our aim is to leave no stone unturned and try our best to find infected cases as early as possible," Mr Gan said.
"We are carrying out surveillance testing for individuals who have been to public places that the cases have visited during the infectious period. This can help us detect cases quickly so that we can ringfence them and prevent further transmission in the community." headtopics.com
READ: COVID-19: Staff placed on leave of absence, 4 wards locked down as Tan Tock Seng Hospital moves to contain clusterWhen asked if some patients and visitors were reportedly not wearing masks in TTSH wards, Assoc Prof Mak said investigations are still ongoing.
"Is it because of not wearing masks or a lack of discipline in maintaining discipline in infection control? Well, that is one possibility that we always look at, but we did note that there was a clustering of cases really around one single ward - ward 9D," he added.
"And we are exploring the possibility that there are other local influences, particularly related to the ward that may have also influenced a super-spreading event occurring, leading to these cases."For instance, authorities are studying the possibility of issues with airflow and ventilation in the ward, among other hypotheses, he said.
Mr Gan noted that other institutions in the healthcare system are stepping up to ensure continuity of care for TTSH patients. Read more: CNA »
Singapore sees ‘several important lessons’ from Tan Tock Seng Hospital COVID-19 cluster
SINGAPORE: Singapore has learnt 'several important lessons' from the COVID-19 cluster at Tan Tock Seng Hospital (TTSH), among them - that the ...
1 day away from being released from SHN and i’m being made to do an extra 7days 🖕🏻. I’ve passed 3 PCR tests, I’m fully vaccinated and not travelled anywhere near the variant countries. RIDICULOUS! It has become acceptable to earmark variants with country names to show where they were first detected. Should the SarsCov2 then also carry the original country's name against it. ? Perception becomes reality and this nomenclature is dangerous.
lawrencewongresign suckerpunch singaporean Let them work things out , we know they will be doing 100% on this When you drag your feet to close the borders the virus sneaks in. Is the risk worth the rewards now ? 1 dead already. Many infected in the 70s upwards. another lockdown and it's another multibillion reserves. Manage with lives as top priority. Money economy can come later
Why I need to move to New Zealand and live there forever... This is worrying trend, we managed to contract all the worst variants in Singapore. I hope Singapore does not go into another lock down. This is alarming! 21 days SHN for Inbound contacts is simply not enough. SHN needs to be increased to a month atleast which is hard but a must to do to safeguard population. Vaccination program should be ramped up with faster pace in the meantime.
