7th Jul 2020

             The Multi-Ministry Taskforce has been closely monitoring the COVID-19 situation. There has been an increase in the number of community cases as we resume more economic and social activities following the end of the Circuit Breaker.  Proactive measures are in place to uncover and contain cases early. Linked cases are detected and isolated quickly through aggressive ring-fencing. Unlinked cases are picked up early from active surveillance and routine testing of targeted groups, and expanded testing for those diagnosed with acute respiratory infection (ARI)[1].

2.               While the number of unlinked current infections in the community remains low, it is indicative of undetected cases in the community. Apart from the early detection and isolation measures in place, continued vigilance and adherence to safe management measures on everyone’s part are important to reduce the spread of infection and protect our loved ones. 

Decline in Total Daily Cases; Continued Effort to Clear Migrant Worker Dormitories

3.              The total daily new cases has been on the decline since the Circuit Breaker period in April and May 2020.  While migrant worker dormitory cases continue to constitute the majority of daily cases, they have fallen. The Inter-agency Taskforce (ITF) is continuing its efforts to systematically test and clear workers and dormitories.

Some Imported Cases; Isolation under SHN Prevents Community Transmission

4.              Over the past week, 20 imported cases were detected. This is after a long period where we did not experience imported cases. The majority of these cases are returning Singapore Citizens and Permanent Residents, and a few are Work Pass or Dependant’s Pass holders who have been approved to return to Singapore.

5.              Our border controls remain tight. Travellers are isolated under Stay-Home Notices (SHN) on arrival, and tested should they become unwell or before they end their SHN. This prevents community transmission from imported cases. Even as we gradually reopen our borders, we will continue to assess the risk, and have strict border controls to protect our Singapore community.

Uptick in Community Cases; Majority are Linked Cases Detected Early by Aggressive Ring-Fencing

6.              In the past week, we have seen an average of 12 new community cases a day, up from around 8 community cases a day in the prior week. Over half of the community cases (57%) since the start of Phase One are linked.

7.              The majority of linked cases are detected through active case finding and aggressive ring-fencing efforts around confirmed cases. Through our contact tracing efforts, close contacts are identified early and put on quarantine quickly. This prevents onward transmission in the community. Our analysis of the recent cases indicate that households are the most common mode of transmission. There are also some transmissions happening at workplaces, especially in settings that are at the frontline of COVID-19 operations. There are fewer transmission taking place through social gatherings for now. This is partly because of the tight restrictions imposed on such activities. Continued vigilance is therefore necessary as we progressively resume more social activities in Phase Two.  

Close to Half of Unlinked Cases are Past Infections; Many in Construction or Construction-related Occupations

8.               Regular testing of targeted groups[2] and testing for those diagnosed with ARI[3]. have helped detect unlinked cases in the community. Of the unlinked cases, about 6 in 10 were asymptomatic, and almost half are likely to be past infections as they tested positive under serology tests.

9.              Notably, about half of community unlinked cases have been from the construction sector or construction-related occupations such as building trades workers and electrical instrument fitters. Serology testing has found that about two-thirds of these construction-related cases are likely to be past infections that are unlikely to be currently infectious, which could have been transmissions from earlier construction or migrant worker clusters. This shows that the construction sector continues to be a higher risk setting for transmission, as the nature of work can make it more challenging to maintain strict safe management and distancing measures. The Building and Construction Authority has been working closely with the industry and relevant Trade Associations and Chambers to implement the COVID-Safe restart criteria before projects are allowed to resume. Regular testing is an important aspect for early detection of cases to reduce further spread.

10.          The remaining unlinked cases in the community continue to be in the low single digits currently. Our ARI testing has scaled up significantly in the recent two weeks, which has helped to pick up these cases. They are an important indicator of underlying community spread. 

Staying Vigilant  

11.          As we resume more activities under Phase Two, we must be prepared for the number of cases to increase. Apart from the early detection and isolation measures that are in place, adherence to strong safe management measures, safe distancing measures and strict infection control measures by everyone is key to reducing spread. Individuals should also use the TraceTogether and SafeEntry applications to facilitate contact tracing. We strongly encourage anyone who is not feeling well to see a doctor, who is best placed to provide clinical assessment including whether testing is needed as a safeguard and precaution, so that cases can be detected early. Through everyone’s collective efforts, we can keep COVID-19 under control while we progressively resume activities safely.

[2] With increased testing capacity, the Multi-Ministry Task Force has expanded community testing to include active surveillance testing of targeted groups who are more vulnerable or have higher risk of exposure to COVID-19. In this regard, we have been conducting regular testing of workers who returned to work in the construction, marine and process sectors, and workers supporting our frontline COVID-19 operations.
