PN must drastically increase Covid-19 targeted testing and implement a National Testing Plan

Media statement by MP for Damansara and DAP National Publicity Secretary, Tony Pua in Kuala Lumpur on 21 July 2021:


Based on rising positivity rate of around 10% today, we are severely under-testing for Covid-19 to detect cases and outbreaks in the community


Yesterday, the Ministry of Health (MoH) reported 12,366 Covid-19 positive cases from 124,519 test samples. That translates to a positivity rate of 9.93%. The positivity rate continues to increase compared to the weekly positivity rate as shown in the chart below. And the increase is despite a recent increase in test sampling since last week.


As can be seen from the chart above, during the first week of MCO 3.0 starting 23 May 2021, MoH carried out 109,601 average daily tests to return 7,631 average daily positive cases or 6.96% positivity.

However, for 6 subsequent weeks until 10 July, MoH actually carried out significantly fewer tests despite high and rising positivity. The positivity rate is well above the World Health Organisation (WHO) threshold of 5% where the spread of Covid-19 is deemed under control.

It was only last week that MoH finally carried out more tests than they did during the first week of MCO 3.0. For week starting 11 July, an average of 120,165 tests were carried out daily, which returned a positivity of 9.35% or 11,237 positive results daily.

The above data tells us a few simple facts:

  • The significant drop in testing – a massive drop of 34% for the week starting 20 June compared to the first week of MCO, has contributed to a major failure to detect tens of thousands of cases in the community which then caused more infections as reflected in the rising positivity rate.
  • When comparing the testing data between the first week of MCO3.0 and the last week (11-17 July), the positivity rate has increased by more than 34% from 6.96% to 9.35%. However, despite an increase in testing last week, it was increased by an average of 9.6% only.

This simply means that we are still severely under-testing for Covid-19 in our community based on the current number of cases uncovered.

In the past, MoH has repeatedly dismissed calls for mass-scale Covid-19 testing across the country ever since last year. Health director-general (DG) Tan Sri Dr Noor Hisham Abdullah favoured the ‘targeted’ approach in Covid-19 testing.


We would like to highlight that we do not have an issue with a ‘targeted testing’ approach. However, there is a stark difference between ‘targeted testing’ and ‘limited testing’. 


What the MoH has in effect been practicing is a ‘limited testing’ approach.


A ‘targeted testing’ approach has to correspond to test outcomes and results. When the tests returns a positivity above 5%, the targeted testing approach should automatically increase the number of tests to a sample size that will return and reduce the positivity to less than 5%.  

Hence, if the positivity rate has effectively risen to 10% as it has over the past few days, it the number of targeted samples to be tested has to effectively double as well in order to meaningfully and effectively record and determine the number of infected in the community. This is the first step towards quarantine and isolation, and where possible contact tracing to prevent the infection rate from spiralling out of control as it had over the past 2 months.

We call upon MoH to drastically increase its targeted testing and put in place a National Testing Plan, as part of a whole of government and whole of nation approach to fighting Covid-19 and its variants. This plan is not for the MoH to execute alone, but for all stakeholders including private hospitals, private clinics, factories and work places, and even individuals via the now available self-test kits. 


We must build a national capacity to test at least 1%, that is approximately 300,000 tests a day as a contingency to deal with any further outbreaks in the future.
