Is a new covid-19 strain responsible for the Minuwangoda outbreak?
Dr. Pradeep Kariyawasam
Former Chief Medical Officer of Health, Colombo Municipal Council.
The total number of Covid-19 patients in the first seven months was around 3,500 but during the past two weeks another 1,600 were found as the result of the Minuwangoda outbreak. I call it the Minuwangoda outbreak as obviously some people have had the virus infection without being reported before it entered the Brandix factory. It has spread its way into farther parts of the country such as Jaffna and Monaragala and the numbers are rising. Gradually more and more districts are getting involved but the numbers are low so far.
We cannot fight this pandemic alone as it has enveloped the whole world and we must study the global spread and the virus strains, especially if we are getting those Sri Lankans stranded abroad back to this country. This is a new disease caused by a new virus of which we have only a little understanding. Although the PCR tests could report a positive result only 50% of the persons show symptoms. It is not known for sure whether a person who has the germ but not showing any symptoms of the disease could infect another person. The virus can survive on surfaces up to 28 days according to new reports. So, this is not only an air-borne disease and the importance of handwashing and sanitizing is highlighted. The incubation period is 5-14 days. The quarantine period is 14 days. We had controlled the disease to a great extent but the arrival of Lankans from abroad changed the situation. Supposing someone gets infected in the plane from another passenger and show symptoms on the 14th day of getting infected and use the same transport back from quarantine centres, they will definitely pass the virus to others. This was noticed and some suggested that the quarantine period should be increased to 21 days thinking that the incubation period was longer, which was not reported by any other country, and later it was decided to quarantine them for another 14 days in their own homes. Even if one infected person gets through the net that is enough for a major outbreak somewhere else which I believe is the present case. That combined with complacency shown by the people who stopped wearing masks, not adhering to social distancing and forgetting about hand-washing obviously created the present situation. In both private and govt sector offices the managers hardly wore masks that set a bad example to their sub-ordinates.
Even with many ups and downs the country managed the disease very well where the forces combined with the health personnel to control the spread. Many lessons were learnt while they were on the job. While treatment procedures adopted were outstanding, the PCR testing was hardly adequate. The reasons are not known but now I believe that it is raised up to 6000 tests a day. Considering that the false negative rate of the test is between 2-29% according the British Medical Journal, and 2-37% as reported by Harvard Medical School, it is necessary to test the same person twice or thrice. The false positive rate is only 4% and therefore if a person has a positive PCR test then it is better to consider that person a Covi-19 patient. This shows that we may be not covering all the persons who are really infected. We went on carrying out tests on so-called high-risk groups in urban areas which was non-productive and a sheer waste of time and money considering that the private hospitals charge between Rs. 6000 to 9000 per test. Random testing also is like trying a find a needle in a haystack which is a waste of resources. While tracing the contacts it is important also to do reverse contact tracing with an open mind not to try to link only to Minuwangoda. This disease doesn’t care whether one is rich or poor. Therefore, it is better to consider testing those who have the symptoms only i.e. with a fever, sore-throat, cough and cold, difficulty in breathing or any one of them. If such a practice is adopted, I am sure the number of positives could be much higher and we may not miss many covid-19 patients.
All is not lost. Although the flu season is on in the Northern Hemisphere, I am sure we could contain the spread of this disease again. Moreover, studies suggest that with covid-19 on the rampage the flu rates are getting lower and that getting flu will temporarily prevent covid-19 infection. Information coming out of the Duke University, USA states that countries with lower covid-19 rates are the countries with high dengue epidemic rates in the recent past which means that there is a possibility of cross-immunity between dengue and covid-19. Also, it states that if one has got dengue fever then there is a chance of a false positive result if the antibody test is done. Is this why we have had lower covid-19 rates? This year we had very low dengue fever incidence so we might not have that advantage too.
What is needed is common sense to prevent further spread of the disease. All hospitals and General Practitioners should try and send those who have the symptoms for PCR testing. Considering that the virus changes with time even slightly, the researchers here must warn if there is a change in the virus strain so that we can be prepared for it. It is known that the virus found in the USA, Canada, Europe is a more transmissible mutant strain, and when one looks at the rate of infections during the past few days maybe it started the present outbreak here too. We know that this is also the dominant strain in India although different lineages are found regionally. The Chief Epidemiologist says that the virus load found in individuals is higher now. The researchers in this country should work hand in glove with those conducting control programmes by monitoring the situation and advising the Ministry of Health. Unfortunately, my experience is not that. Years ago, the professor of Microbiology from Sri Jayewardenepura University came to my office and told me that the dengue virus has changed to Den-3 and an epidemic was imminent but no one was listening to her hence she had decided to come to me. What the officials should do is to support the researchers also by giving data. Even the GMOA is not given data. It is good if strict quarantine regulations are implemented to the letter now. The media should not overdo their act by showing individuals who have unfortunately got the disease which will discourage others from coming out to seek treatment or get tested.

Ranking public services with AI — A roadmap to reviving institutions like SriLankan Airlines
Efficacy measures an organisation’s capacity to achieve its mission and intended outcomes under planned or optimal conditions. It differs from efficiency, which focuses on achieving objectives with minimal resources, and effectiveness, which evaluates results in real-world conditions. Today, modern AI tools, using publicly available data, enable objective assessment of the efficacy of Sri Lanka’s government institutions.
Among key public bodies, the Supreme Court of Sri Lanka emerges as the most efficacious, outperforming the Department of Inland Revenue, Sri Lanka Customs, the Election Commission, and Parliament. In the financial and regulatory sector, the Central Bank of Sri Lanka (CBSL) ranks highest, ahead of the Securities and Exchange Commission, the Public Utilities Commission, the Telecommunications Regulatory Commission, the Insurance Regulatory Commission, and the Sri Lanka Standards Institution.
Among state-owned enterprises, the Sri Lanka Ports Authority (SLPA) leads in efficacy, followed by Bank of Ceylon and People’s Bank. Other institutions assessed included the State Pharmaceuticals Corporation, the National Water Supply and Drainage Board, the Ceylon Electricity Board, the Ceylon Petroleum Corporation, and the Sri Lanka Transport Board. At the lower end of the spectrum were Lanka Sathosa and Sri Lankan Airlines, highlighting a critical challenge for the national economy.
Sri Lankan Airlines, consistently ranked at the bottom, has long been a financial drain. Despite successive governments’ reform attempts, sustainable solutions remain elusive.
Globally, the most profitable airlines operate as highly integrated, technology-enabled ecosystems rather than as fragmented departments. Operations, finance, fleet management, route planning, engineering, marketing, and customer service are closely coordinated, sharing real-time data to maximise efficiency, safety, and profitability.
The challenge for Sri Lankan Airlines is structural. Its operations are fragmented, overly hierarchical, and poorly aligned. Simply replacing the CEO or senior leadership will not address these deep-seated weaknesses. What the airline needs is a cohesive, integrated organisational ecosystem that leverages technology for cross-functional planning and real-time decision-making.
The government must urgently consider restructuring Sri Lankan Airlines to encourage:
=Joint planning across operational divisions
=Data-driven, evidence-based decision-making
=Continuous cross-functional consultation
=Collaborative strategic decisions on route rationalisation, fleet renewal, partnerships, and cost management, rather than exclusive top-down mandates
Sustainable reform requires systemic change. Without modernised organisational structures, stronger accountability, and aligned incentives across divisions, financial recovery will remain out of reach. An integrated, performance-oriented model offers the most realistic path to operational efficiency and long-term viability.
Reforming loss-making institutions like Sri Lankan Airlines is not merely a matter of leadership change — it is a structural overhaul essential to ensuring these entities contribute productively to the national economy rather than remain perpetual burdens.

Why Pi Day?
International Day of Mathematics falls tomorrow
The approximate value of Pi (π) is 3.14 in mathematics. Therefore, the day 14 March is celebrated as the Pi Day. In 2019, UNESCO proclaimed 14 March as the International Day of Mathematics.
Ancient Babylonians and Egyptians figured out that the circumference of a circle is slightly more than three times its diameter. But they could not come up with an exact value for this ratio although they knew that it is a constant. This constant was later named as π which is a letter in the Greek alphabet.
It was the Greek mathematician Archimedes (250 BC) who was able to find an upper bound and a lower bound for this constant. He drew a circle of diameter one unit and drew hexagons inside and outside the circle such that the sides of each hexagon touch the sides of the circle. In mathematics the circle passing through all vertices of a polygon is called a ‘circumcircle’ and the largest circle that fits inside a polygon tangent to all its sides is called an ‘incircle’. The total length of the smaller hexagon then becomes the lower bound of π and the length of the hexagon outside the circle is the upper bound. He realised that by increasing the number of sides of the polygon can make the bounds get closer to the value of Pi and increased the number of sides to 12,24,48 and 60. He argued that by increasing the number of sides will ultimately result in obtaining the original circle, thereby laying the foundation for the theory of limits. He ended up with the lower bound as 22/7 and the upper bound 223/71. He could not continue his research as his hometown Syracuse was invaded by Romans and was killed by one of the soldiers. His last words were ‘do not disturb my circles’, perhaps a reference to his continuing efforts to find the value of π to a greater accuracy.
Archimedes can be considered as the father of geometry. His contributions revolutionised geometry and his methods anticipated integral calculus. He invented the pulley and the hydraulic screw for drawing water from a well. He also discovered the law of hydrostatics. He formulated the law of levers which states that a smaller weight placed farther from a pivot can balance a much heavier weight closer to it. He famously said “Give me a lever long enough and a place to stand and I will move the earth”.
Mathematicians have found many expressions for π as a sum of infinite series that converge to its value. One such famous series is the Leibniz Series found in 1674 by the German mathematician Gottfried Leibniz, which is given below.
π = 4 ( 1 – 1/3 + 1/5 – 1/7 + 1/9 – ………….)
The Indian mathematical genius Ramanujan came up with a magnificent formula in 1910. The short form of the formula is as follows.
π = 9801/(1103 √8)
For practical applications an approximation is sufficient. Even NASA uses only the approximation 3.141592653589793 for its interplanetary navigation calculations.
It is not just an interesting and curious number. It is used for calculations in navigation, encryption, space exploration, video game development and even in medicine. As π is fundamental to spherical geometry, it is at the heart of positioning systems in GPS navigations. It also contributes significantly to cybersecurity. As it is an irrational number it is an excellent foundation for generating randomness required in encryption and securing communications. In the medical field, it helps to calculate blood flow rates and pressure differentials. In diagnostic tools such as CT scans and MRI, pi is an important component in mathematical algorithms and signal processing techniques.
This elegant, never-ending number demonstrates how mathematics transforms into practical applications that shape our world. The possibilities of what it can do are infinite as the number itself. It has become a symbol of beauty and complexity in mathematics. “It matters little who first arrives at an idea, rather what is significant is how far that idea can go.” said Sophie Germain.
Mathematics fans are intrigued by this irrational number and attempt to calculate it as far as they can. In March 2022, Emma Haruka Iwao of Japan calculated it to 100 trillion decimal places in Google Cloud. It had taken 157 days. The Guinness World Record for reciting the number from memory is held by Rajveer Meena of India for 70000 decimal places over 10 hours.
Happy Pi Day!

Sheer rise of Realpolitik making the world see the brink
The recent humanly costly torpedoing of an Iranian naval vessel in Sri Lanka’s Exclusive Economic Zone by a US submarine has raised a number of issues of great importance to international political discourse and law that call for elucidation. It is best that enlightened commentary is brought to bear in such discussions because at present misleading and uninformed speculation on questions arising from the incident are being aired by particularly jingoistic politicians of Sri Lanka’s South which could prove deleterious.
As matters stand, there seems to be no credible evidence that the Indian state was aware of the impending torpedoing of the Iranian vessel but these acerbic-tongued politicians of Sri Lanka’s South would have the local public believe that the tragedy was triggered with India’s connivance. Likewise, India is accused of ‘embroiling’ Sri Lanka in the incident on account of seemingly having prior knowledge of it and not warning Sri Lanka about the impending disaster.
It is plain that a process is once again afoot to raise anti-India hysteria in Sri Lanka. An obligation is cast on the Sri Lankan government to ensure that incendiary speculation of the above kind is defeated and India-Sri Lanka relations are prevented from being in any way harmed. Proactive measures are needed by the Sri Lankan government and well meaning quarters to ensure that public discourse in such matters have a factual and rational basis. ‘Knowledge gaps’ could prove hazardous.
Meanwhile, there could be no doubt that Sri Lanka’s sovereignty was violated by the US because the sinking of the Iranian vessel took place in Sri Lanka’s Exclusive Economic Zone. While there is no international decrying of the incident, and this is to be regretted, Sri Lanka’s helplessness and small player status would enable the US to ‘get away with it’.
Could anything be done by the international community to hold the US to account over the act of lawlessness in question? None is the answer at present. This is because in the current ‘Global Disorder’ major powers could commit the gravest international irregularities with impunity. As the threadbare cliché declares, ‘Might is Right’….. or so it seems.
Unfortunately, the UN could only merely verbally denounce any violations of International Law by the world’s foremost powers. It cannot use countervailing force against violators of the law, for example, on account of the divided nature of the UN Security Council, whose permanent members have shown incapability of seeing eye-to-eye on grave matters relating to International Law and order over the decades.
The foregoing considerations could force the conclusion on uncritical sections that Political Realism or Realpolitik has won out in the end. A basic premise of the school of thought known as Political Realism is that power or force wielded by states and international actors determine the shape, direction and substance of international relations. This school stands in marked contrast to political idealists who essentially proclaim that moral norms and values determine the nature of local and international politics.
While, British political scientist Thomas Hobbes, for instance, was a proponent of Political Realism, political idealism has its roots in the teachings of Socrates, Plato and latterly Friedrich Hegel of Germany, to name just few such notables.
On the face of it, therefore, there is no getting way from the conclusion that coercive force is the deciding factor in international politics. If this were not so, US President Donald Trump in collaboration with Israeli Rightist Premier Benjamin Natanyahu could not have wielded the ‘big stick’, so to speak, on Iran, killed its Supreme Head of State, terrorized the Iranian public and gone ‘scot-free’. That is, currently, the US’ impunity seems to be limitless.
Moreover, the evidence is that the Western bloc is reuniting in the face of Iran’s threats to stymie the flow of oil from West Asia to the rest of the world. The recent G7 summit witnessed a coming together of the foremost powers of the global North to ensure that the West does not suffer grave negative consequences from any future blocking of western oil supplies.
Meanwhile, Israel is having a ‘free run’ of the Middle East, so to speak, picking out perceived adversarial powers, such as Lebanon, and militarily neutralizing them; once again with impunity. On the other hand, Iran has been bringing under assault, with no questions asked, Gulf states that are seen as allying with the US and Israel. West Asia is facing a compounded crisis and International Law seems to be helplessly silent.
Wittingly or unwittingly, matters at the heart of International Law and peace are being obfuscated by some pro-Trump administration commentators meanwhile. For example, retired US Navy Captain Brent Sadler has cited Article 51 of the UN Charter, which provides for the right to self or collective self-defence of UN member states in the face of armed attacks, as justifying the US sinking of the Iranian vessel (See page 2 of The Island of March 10, 2026). But the Article makes it clear that such measures could be resorted to by UN members only ‘ if an armed attack occurs’ against them and under no other circumstances. But no such thing happened in the incident in question and the US acted under a sheer threat perception.
Clearly, the US has violated the Article through its action and has once again demonstrated its tendency to arbitrarily use military might. The general drift of Sadler’s thinking is that in the face of pressing national priorities, obligations of a state under International Law could be side-stepped. This is a sure recipe for international anarchy because in such a policy environment states could pursue their national interests, irrespective of their merits, disregarding in the process their obligations towards the international community.
Moreover, Article 51 repeatedly reiterates the authority of the UN Security Council and the obligation of those states that act in self-defence to report to the Council and be guided by it. Sadler, therefore, could be said to have cited the Article very selectively, whereas, right along member states’ commitments to the UNSC are stressed.
However, it is beyond doubt that international anarchy has strengthened its grip over the world. While the US set destabilizing precedents after the crumbling of the Cold War that paved the way for the current anarchic situation, Russia further aggravated these degenerative trends through its invasion of Ukraine. Stepping back from anarchy has thus emerged as the prime challenge for the world community.
