Is a new covid-19 strain responsible for the Minuwangoda outbreak?

Published

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.

Rethinking post-disaster urban planning: Lessons from Peradeniya

Published

on

University of Peradeniya

A recent discussion by former Environment Minister, Eng. Patali Champika Ranawaka on the Derana 360 programme has reignited an important national conversation on how Sri Lanka plans, builds and rebuilds in the face of recurring disasters.

His observations, delivered with characteristic clarity and logic, went beyond the immediate causes of recent calamities and focused sharply on long-term solutions—particularly the urgent need for smarter land use and vertical housing development.

Ranawaka’s proposal to introduce multistoried housing schemes in the Gannoruwa area, as a way of reducing pressure on environmentally sensitive and disaster-prone zones, resonated strongly with urban planners and environmentalists alike.

It also echoed ideas that have been quietly discussed within academic and conservation circles for years but rarely translated into policy.

One such voice is that of Professor Siril Wijesundara, Research Professor at the National Institute of Fundamental Studies (NIFS) and former Director General of the Royal Botanic Gardens, Peradeniya, who believes that disasters are often “less acts of nature and more outcomes of poor planning.”

Professor Siril Wijesundara

“What we repeatedly see in Sri Lanka is not merely natural disasters, but planning failures,” Professor Wijesundara told The Island.

“Floods, landslides and environmental degradation are intensified because we continue to build horizontally, encroaching on wetlands, forest margins and river reservations, instead of thinking vertically and strategically.”

The former Director General notes that the University of Peradeniya itself offers a compelling case study of both the problem and the solution. The main campus, already densely built and ecologically sensitive, continues to absorb new faculties, hostels and administrative buildings, placing immense pressure on green spaces and drainage systems.

“The Peradeniya campus was designed with landscape harmony in mind,” he said. “But over time, ad-hoc construction has compromised that vision. If development continues in the same manner, the campus will lose not only its aesthetic value but also its ecological resilience.”

Professor Wijesundara supports the idea of reorganising the Rajawatte area—located away from the congested core of the university—as a future development zone. Rather than expanding inward and fragmenting remaining open spaces, he argues that Rajawatte can be planned as a well-designed extension, integrating academic, residential and service infrastructure in a controlled manner.

Crucially, he stresses that such reorganisation must go hand in hand with social responsibility, particularly towards minor staff currently living in the Rajawatte area.

“These workers are the backbone of the university. Any development plan must ensure their dignity and wellbeing,” he said. “Providing them with modern, safe and affordable multistoried housing—especially near the railway line close to the old USO premises—would be both humane and practical.”

According to Professor Wijesundara, housing complexes built near existing transport corridors would reduce daily commuting stress, minimise traffic within the campus, and free up valuable land for planned academic use.

More importantly, vertical housing would significantly reduce the university’s physical footprint.

Drawing parallels with Ranawaka’s Gannoruwa proposal, he emphasised that vertical development is no longer optional for Sri Lanka.

“We are a small island with a growing population and shrinking safe land,” he warned.

“If we continue to spread out instead of building up, disasters will become more frequent and more deadly. Vertical housing, when done properly, is environmentally sound, economically efficient and socially just.”

Peradeniya University flooded

The veteran botanist also highlighted the often-ignored link between disaster vulnerability and the destruction of green buffers.

“Every time we clear a lowland, a wetland or a forest patch for construction, we remove nature’s shock absorbers,” he said.

“The Royal Botanic Gardens has survived floods for over a century precisely because surrounding landscapes once absorbed excess water. Urban planning must learn from such ecological wisdom.”

Professor Wijesundara believes that universities, as centres of knowledge, should lead by example.

“If an institution like Peradeniya cannot demonstrate sustainable planning, how can we expect cities to do so?” he asked. “This is an opportunity to show that development and conservation are not enemies, but partners.”

As climate-induced disasters intensify across the country, voices like his—and proposals such as those articulated by Patali Champika Ranawaka—underscore a simple but urgent truth: Sri Lanka’s future safety depends not only on disaster response, but on how and where we build today.

The challenge now lies with policymakers and planners to move beyond television studio discussions and academic warnings, and translate these ideas into concrete, people-centred action.

Superstition – Major barrier to learning and social advancement

Published

on

At the initial stage of my six-year involvement in uplifting society through skill-based initiatives, particularly by promoting handicraft work and teaching students to think creatively and independently, my efforts were partially jeopardized by deep-rooted superstition and resistance to rational learning.

Superstitions exerted a deeply adverse impact by encouraging unquestioned belief, fear, and blind conformity instead of reasoning and evidence-based understanding. In society, superstition often sustains harmful practices, social discrimination, exploitation by self-styled godmen, and resistance to scientific or social reforms, thereby weakening rational decision-making and slowing progress. When such beliefs penetrate the educational environment, students gradually lose the habit of asking “why” and “how,” accepting explanations based on fate, omens, or divine intervention rather than observation and logic.

Initially, learners became hesitant to challenge me despite my wrong interpretation of any law, less capable of evaluating information critically, and more vulnerable to misinformation and pseudoscience. As a result, genuine efforts towards social upliftment were obstructed, and the transformative power of education, which could empower individuals economically and intellectually, was weakened by fear-driven beliefs that stood in direct opposition to progress and rational thought. In many communities, illnesses are still attributed to evil spirits or curses rather than treated as medical conditions. I have witnessed educated people postponing important decisions, marriages, journeys, even hospital admissions, because an astrologer predicted an “inauspicious” time, showing how fear governs rational minds.

While teaching students science and mathematics, I have clearly observed how superstition acts as a hidden barrier to learning, critical thinking, and intellectual confidence. Many students come to the classroom already conditioned to believe that success or failure depends on luck, planetary positions, or divine favour rather than effort, practice, and understanding, which directly contradicts the scientific spirit. I have seen students hesitate to perform experiments or solve numerical problems on certain “inauspicious” days.

In mathematics, some students label themselves as “weak by birth”, which creates fear and anxiety even before attempting a problem, turning a subject of logic into a source of emotional stress. In science classes, explanations based on natural laws sometimes clash with supernatural beliefs, and students struggle to accept evidence because it challenges what they were taught at home or in society. This conflict confuses young minds and prevents them from fully trusting experimentation, data, and proof.

Worse still, superstition nurtures dependency; students wait for miracles instead of practising problem-solving, revision, and conceptual clarity. Over time, this mindset damages curiosity, reduces confidence, and limits innovation, making science and mathematics appear difficult, frightening, or irrelevant. Many science teachers themselves do not sufficiently emphasise the need to question or ignore such irrational beliefs and often remain limited to textbook facts and exam-oriented learning, leaving little space to challenge superstition directly. When teachers avoid discussing superstition, they unintentionally reinforce the idea that scientific reasoning and superstitious beliefs can coexist.

To overcome superstition and effectively impose critical thinking among students, I have inculcated the process to create a classroom culture where questioning was encouraged and fear of being “wrong” was removed. Students were taught how to think, not what to think, by consistently using the scientific method—observation, hypothesis, experimentation, evidence, and conclusion—in both science and mathematics lessons. I have deliberately challenged superstitious beliefs through simple demonstrations and hands-on experiments that allow students to see cause-and-effect relationships for themselves, helping them replace belief with proof.

Many so-called “tantrik shows” that appear supernatural can be clearly explained and exposed through basic scientific principles, making them powerful tools to fight superstition among students. For example, acts where a tantrik places a hand or tongue briefly in fire without injury rely on short contact time, moisture on the skin, or low heat transfer from alcohol-based flames rather than divine power.

“Miracles” like ash or oil repeatedly appearing from hands or idols involve concealment or simple physical and chemical tricks. When these tricks are demonstrated openly in classrooms or science programmes and followed by clear scientific explanations, students quickly realise how easily perception can be deceived and why evidence, experimentation, and critical questioning are far more reliable than blind belief.

Linking concepts to daily life, such as explaining probability to counter ideas of luck, or biology to explain illness instead of supernatural causes, makes rational explanations relatable and convincing.

Another unique example that I faced in my life is presented here. About 10 years ago, when I entered my new house but did not organise traditional rituals that many consider essential for peace and prosperity as my relatives believed that without them prosperity would be blocked.  Later on, I could not utilise the entire space of my newly purchased house for earning money, largely because I chose not to perform certain rituals.

While this decision may have limited my financial gains to some extent, I do not consider it a failure in the true sense. I feel deeply satisfied that my son and daughter have received proper education and are now well settled in their employment, which, to me, is a far greater achievement than any ritual-driven expectation of wealth. My belief has always been that a house should not merely be a source of income or superstition-bound anxiety, but a space with social purpose.

Instead of rituals, I strongly feel that the unused portion of my house should be devoted to running tutorials for poor and underprivileged students, where knowledge, critical thinking, and self-reliance can be nurtured. This conviction gives me inner peace and reinforces my faith that education and service to society are more meaningful measures of success than material profit alone.

Though I have succeeded to some extent, this success has not been complete due to the persistent influence of superstition.

Race hate and the need to re-visit the ‘Clash of Civilizations’

Published

Australian Prime Minister Anthony Albanese: ‘No to race hate’

Australian Prime Minister Anthony Albanese has done very well to speak-up against and outlaw race hate in the immediate aftermath of the recent cold-blooded gunning down of several civilians on Australia’s Bondi Beach. The perpetrators of the violence are believed to be ardent practitioners of religious and race hate and it is commendable that the Australian authorities have lost no time in clearly and unambiguously stating their opposition to the dastardly crimes in question.

The Australian Prime Minister is on record as stating in this connection: ‘ New laws will target those who spread hate, division and radicalization. The Home Affairs Minister will also be given new powers to cancel or refuse visas for those who spread hate and a new taskforce will be set up to ensure the education system prevents, tackles and properly responds to antisemitism.’

It is this promptness and single-mindedness to defeat race hate and other forms of identity-based animosities that are expected of democratic governments in particular world wide. For example, is Sri Lanka’s NPP government willing to follow the Australian example? To put the record straight, no past governments of Sri Lanka initiated concrete measures to stamp out the evil of race hate as well but the present Sri Lankan government which has pledged to end ethnic animosities needs to think and act vastly differently. Democratic and progressive opinion in Sri Lanka is waiting expectantly for the NPP government’ s positive response; ideally based on the Australian precedent to end race hate.

Meanwhile, it is apt to remember that inasmuch as those forces of terrorism that target white communities world wide need to be put down their counterpart forces among extremist whites need to be defeated as well. There could be no double standards on this divisive question of quashing race and religious hate, among democratic governments.

The question is invariably bound up with the matter of expeditiously and swiftly advancing democratic development in divided societies. To the extent to which a body politic is genuinely democratized, to the same degree would identity based animosities be effectively managed and even resolved once and for all. To the extent to which a society is deprived of democratic governance, correctly understood, to the same extent would it experience unmanageable identity-bred violence.

This has been Sri Lanka’s situation and generally it could be stated that it is to the degree to which Sri Lankan citizens are genuinely constitutionally empowered that the issue of race hate in their midst would prove manageable. Accordingly, democratic development is the pressing need.

While the dramatic blood-letting on Bondi Beach ought to have driven home to observers and commentators of world politics that the international community is yet to make any concrete progress in the direction of laying the basis for an end to identity-based extremism, the event should also impress on all concerned quarters that continued failure to address the matters at hand could prove fatal. The fact of the matter is that identity-based extremism is very much alive and well and that it could strike devastatingly at a time and place of its choosing.

It is yet premature for the commentator to agree with US political scientist Samuel P. Huntingdon that a ‘Clash of Civilizations’ is upon the world but events such as the Bondi Beach terror and the continuing abduction of scores of school girls by IS-related outfits, for instance, in Northern Africa are concrete evidence of the continuing pervasive presence of identity-based extremism in the global South.

As a matter of great interest it needs mentioning that the crumbling of the Cold War in the West in the early nineties of the last century and the explosive emergence of identity-based violence world wide around that time essentially impelled Huntingdon to propound the hypothesis that the world was seeing the emergence of a ‘Clash of Civilizations’. Basically, the latter phrase implied that the Cold War was replaced by a West versus militant religious fundamentalism division or polarity world wide. Instead of the USSR and its satellites, the West, led by the US, had to now do battle with religion and race-based militant extremism, particularly ‘Islamic fundamentalist violence’ .

Things, of course, came to a head in this regard when the 9/11 calamity centred in New York occurred. The event seemed to be startling proof that the world was indeed faced with a ‘Clash of Civilizations’ that was not easily resolvable. It was a case of ‘Islamic militant fundamentalism’ facing the great bulwark, so to speak, of ‘ Western Civilization’ epitomized by the US and leaving it almost helpless.

However, it was too early to write off the US’ capability to respond, although it did not do so by the best means. Instead, it replied with military interventions, for example, in Iraq and Afghanistan, which moves have only earned for the religious fundamentalists more and more recruits.

Yet, it is too early to speak in terms of a ‘Clash of Civilizations’. Such a phenomenon could be spoken of if only the entirety of the Islamic world took up arms against the West. Clearly, this is not so because the majority of the adherents of Islam are peaceably inclined and want to coexist harmoniously with the rest of the world.

However, it is not too late for the US to stop religious fundamentalism in its tracks. It, for instance, could implement concrete measures to end the blood-letting in the Middle East. Of the first importance is to end the suffering of the Palestinians by keeping a tight leash on the Israeli Right and by making good its boast of rebuilding the Gaza swiftly.

Besides, the US needs to make it a priority aim to foster democratic development worldwide in collaboration with the rest of the West. Military expenditure and the arms race should be considered of secondary importance and the process of distributing development assistance in the South brought to the forefront of its global development agenda, if there is one.

If the fire-breathing religious demagogue’s influence is to be blunted worldwide, then, it is development, understood to mean equitable growth, that needs to be fostered and consolidated by the democratic world. In other words, the priority ought to be the empowerment of individuals and communities. Nothing short of the latter measures would help in ushering a more peaceful world.
