Containing The Impact Of Greater Klang Valley’s Covid-19 Outbreak — Dr Chong Chee Kheong

It is important to appreciate that the size of the outbreak is far larger than the numbers detected each day.

It has been just over two weeks since we have formed the Greater Klang Valley Special Task Force (GKV STF) to deal with the huge Covid-19 outbreak in the area. The GKV STF has a good team from the Ministry of Health (MOH), the army, and external experts. We have been working continuously to put into place measures to contain the impact of the outbreak. Saving lives is our priority. 

The rising numbers of infections and deaths indicates a dire situation, one that is very evident to the public. Covid-19 infections are very widespread in the community, and the hospital capacity in the Greater Klang Valley, including intensive care unit (ICU) capacity, is stretched to the maximum.

Why Are Numbers Still Rising Despite The Vaccination Ramp-Up?

Many are asking this question. It is important to appreciate that the size of the outbreak is far larger than the numbers detected each day.

Many asymptomatic or pre-symptomatic individuals, who are not aware of their infection, are spreading the virus. Remember that the vaccine effectiveness is best two weeks after the second dose, so this takes time.

An important contribution is the Delta variant, which has a high infectivity rate. In addition, we recognise, from the experience of and data from nations with high vaccination rates, that infections can still occur due to the Delta variant, although hospitalisations and severe infections are significantly reduced.  

What Are The Key Measures Taken To Stem The Outbreak?

The GKV STF has put in place a number of strategic measures to optimise care services, reduce virus transmission, and support the community and health care workers.

Given the current situation, outbreak management interventions have shifted from containment to mitigation efforts, with the objective of preventing deaths and minimising the spread of disease. Some of the key initiatives include:

  • Increasing the capacity of beds, ICU care, oxygen supply, manpower deployment and use of volunteers. Moving non-Covid-19 patients to private hospitals is also helping to free up beds. Support from our army colleagues has been invaluable in terms of logistics and manpower.
  • Strengthening Covid-19 Assessment Centres (CAC) by offering virtual CACs for asymptomatic and mildly symptomatic patients and enhanced home monitoring management.
  • Offering more RTK-Ag tests to health clinics and general practitioners via sales of Medical Device Authority-approved test kits to allow for wider testing. Home saliva test kits for self-testing are also available in pharmacies for the public to purchase and test themselves.
  • Improving support for frontliners, as well as strengthening social and emotional support systems for the public.
  • Acquiring and allocating funding for the purpose of procuring additional medical equipment and medication.
  • Improving our communication with the public on critical issues and keeping the public updated.

Health care workers at hospitals, health facilities and management areas are exhausted, but we are still here for the public, and will continue to work to overcome this crisis. 

What Can Members Of The Public Do?

We would like to thank the members of the public who have cooperated in this emergency by limiting their social contact and following standard operating procedures (SOPs).

There are some key measures you can take to help yourself, your family, the community and health care services. We can break the transmission of the virus to others by doing these.

  • If you are in the Greater Klang Valley and have any symptoms, you should consider yourself as possibly infected and get tested.
  • Once you are confirmed positive, please home isolate, notify yourself and do self-monitoring frequently through the MySejahtera application. Home isolation is for asymptomatic and mildly symptomatic patient who do not need hospitalisation and will recover. We do not want to congest hospitals with mild cases so that treatment for severe cases can be prioritised. MOH staff members will contact those who have been red-flagged as posing a high risk, and request them to come to the nearest CAC or hospital.
  • If you are positive, please inform all those you have been in contact with to quarantine for 10 days. Testing is not necessary, unless they develop symptoms. What is important is to stay at home and monitor your condition daily.
  • Members of the public who think they have been exposed but are not identified as close contacts are encouraged to test at private health facilities; this may include doing a saliva-based self-test.
  • Vaccination will greatly reduce the risk of infection, so register and get vaccinated as soon as you get an appointment. Those who are contacts of positive cases should defer vaccination for at least 10 days.
  • We appeal to the community to support us. Some can volunteer to help at the CACs, health centres or hospitals. Others can volunteer to help boost social and emotional support systems for the public.

As we encourage more self-testing and RTK-Ag use, we can expect the number of cases to rise in the next few days. Do not be alarmed by this; we need to identify as many cases as possible to reduce transmission in the community.

As more of these positive cases and their contacts are isolated and quarantined, cases will start to gradually come down in the weeks to come. Once that happens, the testing will be re-strategised to ensure effective detection of cases for isolation and monitoring.

This crisis is the worst that we have faced as a community and health care service in our generation. We have not given up and will persevere to offer the best that we can.

We thank you for understanding our limitations and for the enormous groundswell of support that we have received.
