Need for rapid expansion in testing for COVID 19 in Sri Lanka

Need for rapid expansion in testing for COVID 19 in Sri Lanka

31 March 2020 09:52 am

As we come to the end of the ‘official quarantine’ period and begin to relax the ‘lock down’ within Sri Lanka but keeping the ‘international lock down’ in place,  we need to look at how the SARS-CoV-2 virus which causes COVID -19 behaved in other countries. (please see graph below)


Based on actual case numbers from the countries given in the graph Sri Lanka can expect an upsurge in the number of COVID 19 cases in the coming weeks. This may get further aggravated during the upcoming Sinhalese and Tamil New Year in mid-April 2020 (week 6) where we can expect mass internal migration of fellow citizens within the country.

This calls for the health (both state and private sector) and non-health sectors to act in a pre-emptive manner to deal with the inevitable morbidity and morality which is to be expected. The health authorities should as per the WHO appeal use ALL available health resources within the country to deal with the health outcomes and outputs of the pandemic to contain and mitigate it and sustain such control over time.

A key scientific tool in containing and mitigation the spread of the virus is to know with certainty who has the virus and where those who have the virus are located geographically. THE ONLY WAY OF DOING THIS IS TO TEST FOR THE VIRUS. 

Therefor, there is a dire need to rapidly increase and expand the testing of our citizens if we as a country want to have a positive impact on the pandemic in our country and there by secure the health and wellbeing of our fellow countrymen. The strongest point of our response to the pandemic from a healthcare perspective should be how we improve our weakest point which at the moment is testing for COVID -19.  
 
Please consider this appeal as one OF HIGH PRIORITY- WE HAVE ONLY ONE CHANCE TO GET THIS RIGHT – THERE IS NO PLAN ‘B’.

I give below comments from my colleagues on the issue of the need for rapid expansion Testing for COVID -19 in the Sri Lankan population.


Comment 1
If we do not expand testing and identify those with the virus the curfews would be useless. In addition we need to test the exposed healthcare workers and either clear them as soon as possible so that they can continue to work after the minimum period of isolation or send them for treatment as soon as possible. Otherwise there will be no one to work – like at DHM now where all consultant OBGYNs except for the Prof Unit one are on self-isolation at home

I looked at the list of lab equipment that the Ministry of Health has requested from donors. I can not understand the logic behind the genetic equipment that they want include 9 RT PCR machines presumably to set up 9 labs in different hospitals. The cost of the equipment that the ministry is looking for is above 300 million rupees, nothing less. Even if you get the money for these equipment, constructing the labs, bringing down equipment, installing and commissioning them, hiring people, training them, trouble shoot assays etc. will take six to nine months. As you know I am taking from experience. And all of us know how the government system works.

In the meantime there are labs in universities – Colombo, SJP, Kelaniya, Peradeniya, KDU and the private sector Asiri, Durdens, Nawaloka, Lanka hospitals and SLINTEC that have already functioning labs with RT PCR machines. All you have to do is get the kits and pay for the overheads. I know the universities and the private sector will do it as a national need. You will be up and running by next week. We need testing to be started now. Last Friday’s and this morning’s incidents where people were freely mingling in markets would have speeded up the spread. If we are not detecting cases, the reason is we are not testing.

Comment 2
We cannot be complacent. We are sitting on the tip of the iceberg. Our testing is limited to PCR at MRI and JPU. We are not looking out to detect and track cases actively. We are passive: only a selected lot of those seeking treatment are tested. If we do not actively detect the iceberg would become a volcano. We should now go for rapid slide tests similar to NS1.

Comment 3
The current lockdown (national curfews, work at home, school closures) plus MOH actively tracing contacts of foreign arrivals should work in controlling the current outbreak and bringing cases down to zero within two weeks.

MOH’s policy will work in stopping the epidemic, but this policy cannot be sustained. The economy is at a standstill, unemployment will rise, businesses will go bankrupt, living standards will fall, and the government has no revenue. We need to allow businesses and schools to re-open to restart normal life and get the economy going. 

We also need to open our ports, even on a restricted basis. But allowing foreign arrivals will import the virus again, since it has now spread to every country in the world. This is not going to change for the next 12 months. If we open the airport and keep businesses and schools open, then the virus will re-enter and spark a new outbreak, and the government will have no alternative to shutting the airport once again and imposing curfew.

The only solution that allows us to keep our airport open and allows business and schools to stay open is to vastly expand our testing capacity. Much more extensive testing as in Singapore and Korea would allow us to manage the risk of the virus coming in again and allow MOH to know much earlier when an outbreak is developing, allowing much faster corrective action and avoiding lockdowns. More extensive testing means increasing our testing capacity by at least ten fold so we can test up to 10,000 people a day in an emergency. This capacity will also allow us to adopt Singapore’s policy of testing arrivals to further protect the country, which is probably the safest approach if we want to open the airport.
