1. Testing is a critical enabler of our fight against COVID-19. The Multi-Ministry Taskforce has been steadily building up our national capacity to conduct tests for COVID-19. From an average of 2,900 tests per day in early April, we are now able to conduct more than 8,000 tests per day. To date, Singapore has tested about 2,100 per 100,000 persons. In comparison, the US has tested 1,600 per 100,000 and the UK 1,000 per 100,000. The higher intensity of testing allows us to pick up far more cases than many other countries.

2. We have taken steps to continue building up our testing capacity over the coming weeks and months. Even as we do so, we will continue to prioritise our existing testing capacity based on public health considerations.

Testing for Diagnosis and Surveillance


3. Testing is used for three key purposes. First, for diagnosis in order to provide the appropriate treatment early for persons who are unwell. Second, for active case finding in order to identity infected individuals early and isolate them. Contact tracing around confirmed cases allows us to ring-fence any clusters, and prevent further transmissions. And third, for surveillance purposes, in particular of groups at higher risk of contracting or transmitting the disease.

4. Such testing is done systematically across our hospitals, polyclinics and general practitioner clinics. We test high risk groups showing symptoms of acute respiratory infection (ARI), such as those who are close contacts of confirmed cases, those with travel history, patients already diagnosed with pneumonia, or patients with prolonged ARI. We also conduct testing as a means of general surveillance to detect signs of community spread and to pick up unlinked cases.
   
Testing in the Migrant Worker Dormitories

5. A similar testing strategy is applied to our migrant worker community, including those living in dormitories. The Ministry of Health (MOH) has been testing close to 3,000 migrant workers residing at the dormitories every day, and will continue to do more tests. Many of these workers showed no symptoms when they were tested. In most countries, people who are asymptomatic are not tested. To date, more than 21,000 migrant workers living in dormitories have been tested. This means that we have tested about one in 15 workers in dormitories (or 6,500 per 100,000), far higher than the testing rates seen in countries like South Korea (one in 90, or 1,100 per 100,000).

6. This aggressive testing regime enables us to determine the extent of infection in the dormitories. Those who are confirmed with COVID-19 infection will be reported in the daily tally of newly confirmed cases. We started with the dormitories with a higher incidence of infections, and are continuing to test the workers in the other dormitories.

7. Due to the need to prioritise, we are not be able to test all in the dormitories at one go. But if any worker were to report sick or show ARI symptoms, we will immediately pull aside and isolate the worker from his room-mates, and ensure that he receives the necessary medical care. This allows us to provide medical care quickly to the symptomatic foreign workers, and to ensure that those with higher risk factors or have more severe illnesses are transferred to receive care at our healthcare institutions.

8. One urgent priority is to test migrant workers who have moved out of the dormitories but are continuing to work in essential services. This is to reduce the risk of transmission in workplaces and to the wider community.

Testing for Protection and Monitoring

9. Finally, we are doing more tests to protect vulnerable groups. For instance, we are testing the staff at nursing homes where there is close contact with seniors, as well as healthcare workers and frontline officers who have regular contact with confirmed cases. This will help to ensure that they continue to stay healthy, and receive medical treatment promptly if required.

10. As more testing capacity is brought on-stream, we will gradually expand testing to the wider pool of workers in order to ensure the continuity of critical functions and services. This is important, as it will also enable us to progressively resume economic activities beyond the circuit breaker period.

Holistic Strategy

11. While testing is important, it has to be part of a broader strategy to fight COVID-19. Testing alone cannot substitute for other important measures like safe distancing and infection control. Individual responsibility in upholding good personal hygiene, minimising contact, and seeing a doctor immediately when sick are all critical aspects of the overall strategy. Together, we can slow down transmissions, beat the virus, and emerge stronger after the crisis.
