If one looks at the history of advice regarding the wearing of masks as an effective COVID-19 control measure, it has gone through a full 180-degree swing. In the initial phases of the pandemic, even the World Health Organisation (WHO) was not convinced that wearing masks was of any benefit. Our health authorities followed suit, as they always do in any situation where the WHO pontificates. Then the research scientists showed very clearly the benefits of wearing masks and after virtually a Herculean effort on the part of the scientific community, it was agreed that all should wear masks. Now, at least in our emerald isle, it has become law and at present the police even go after people who are not wearing masks and take steps to prosecute them. It has become like a kind of a mandatory second nature for all of us to wear masks.
Masks, of course, have to be worn properly for optimal benefits. This has been said over and over, again and again. With more contagious variants of the coronavirus spreading and optimal vaccination still months away for many people, all over the world, experts agree that it is time to think even harder about how well the face masks are protecting people.
Now enter DOUBLE MASKING …In a recent statement, the Director of the National Institute of Allergy and Infectious Diseases (NIAID) of the USA, Dr. Anthony Fauci, a foremost authority on COVID-19, stated that he favours double-masking as a further measure to protect against even the new and more infectious Covid-19 variants, like the UK and South African strains, as well as other similar mutant variants that may arise with time. These new recommendations are in line with the regulations being currently imposed across Europe, where medical-grade face masks like the N95 and the FFP2/3, rather than cloth masks, are becoming mandatory in public spaces.
Why the sudden change? More importantly yet, how does one double-mask correctly? Here’s what you need to know. Why Is Double-Masking Necessary? Doubling-Up on Masks is perhaps the need of the hour. When it comes to double-masking, it all boils down to extra protection. As Dr. Fauci further stated in an interview with the Today Show, “If you have a physical covering with one layer, and then you put another layer on, it just makes common sense that it is more likely to be more effective”.
The main reason why the extra protection is necessary, now more than ever, is that the new Covid-19 variants are more contagious than the original strain of the SARS-CoV-2 virus. As has been pointed out repeatedly, it is easier for these new Covid-19 mutations to bind to human cells. Therefore, minimizing the number of novel coronavirus particles in the air that enters the human respiratory system is the key, and the easiest way to do so is to make sure that everyone is wearing masks that offer the best possible protection. One way to do this is by wearing two masks. It is of course quite important to cover our noses and mouths completely and for both masks to fit snugly. Not only will double-masking help to protect others if someone in a crowd has Covid-19, but it will also decrease every individual mask wearer’s risk of contracting the disease.
All in all, wearing two masks is a better shield between you and the novel coronavirus. But why are doctors not advising us to wear three, four, or even five masks at the same time? More layers must surely be better. However, the main reason why that is not a good idea for most people is that wearing multiple masks will make it difficult for you to breathe, depending on the material. “You can pack on 10 layers, but what you do is to lose breathability, become quite uncomfortable and you have overdone the filtering capacity that you want” states Onyema Ogbuagu, an infectious diseases specialist and the primary investigator of Yale’s Pfizer COVID-19 Clinical Trial.
How to Double-Mask correctly? There are a few things to keep in mind if you decide to start double-masking. Here are some key points: –
Which masks are the best to combine?
Research shows that N95 masks offer the best filtration against the novel coronavirus. That being said, these masks may not be the best choice for most people because putting on and breathing in an N95 may be quite tough, especially if you have to wear it for hours. Still, if you can handle it, wearing an N95 mask is the gold standard. It is, however, not your only option. Ideally, you just want to use masks that offer both sufficient air filtration and breathability. A worthy alternative to N95 masks is a combination of a cloth mask or a surgical mask on top of a KN95 mask, which is a modification of the N95 mask. Keep in mind that by “cloth mask”, experts mean a face mask that consists of at least two layers of tightly-knit material, and certainly not a bandana handkerchief or a neck gaiter or a scarf.
How should we layer the face masks?
According to infectious disease experts, the best way to wear two masks is to start with the mask that offers the best air filtration and then wear the other mask, usually a cloth mask, over it. Therefore, put on the KN95 or a surgical mask first, and then wear the cloth mask over it. Make sure there are no gaps on the sides of the masks and they provide a tight fit. That manoeuvre will ensure that no contaminated air will be able to sneak in from the sides.
All in all, the idea of double-masking is pretty straightforward, and it is definitely worth a shot, especially when you have to commute by public transportation or have to spend time in populated areas. However, experts are of the opinion that it is generally better for someone to even wear a single mask properly than to wear two masks improperly. Of course, if one could wear two masks properly, then that would probably be best. The philosophy that “one mask is good, two masks are better, is probably true”, said Dr Georges Benjamin, Executive Director of the American Public Health Association. He further stated “I would prefer that somebody wore one mask properly than two masks improperly, but if you can wear two masks properly, that’s great”.
Whether you’re doubling up, wearing an N95, or just donning your favourite fabric mask, the most important thing to do is to make sure that you are wearing it properly. Masks should cover your nose and mouth and be as tight to your face as possible, according to the Centres for Disease Control in USA.
Experts say that the coronavirus variants do not have superpowers to penetrate masks better than the older versions of the virus. But when they do get through, it is more likely that a person will get sick. There is still a lot we do not know about the variants or what makes them more contagious. It could be that they are better at entering cells, or that they produce higher viral loads, meaning that when an infected person talks or coughs, they’re spewing out more viral particles.
Yet for all this, what they do have is the ability to exploit any kind of lapses in the way you wear those masks. Therefore, if you have got a flimsy mask on or if you have got a mask that you do not wear that well … it is going to be less forgiving when you are dealing with a new variant,
Until more people are vaccinated, just keep physical distancing and wearing masks, and avoid mixing in crowds indoors. Of course, masks are just one way to reduce your risk of transmitting and spreading COVID-19, and everyone should continue distancing, avoiding crowds, limiting time indoors with people outside your household, and staying home as much as possible. There is no way in which these can be relaxed, at least not as yet.
Whatever it is, try to do a little bit better job at both the masking and all the different prevention steps that all of us have been following to try to get everybody past that finish line where we have enough people vaccinated to be able to spend less attention on these very same things. Public cooperation in that scenario is the holy grail on which we have to depend on, relentlessly.

Trade preferences to support post-Ditwah reconstruction
The manner in which the government succeeded in mobilising support from the international community, immediately after the devastating impact of Cyclone Ditwah, may have surprised many people of this country, particularly because our Opposition politicians were ridiculing our “inexperienced” government, in the recent past, for its inability to deal with the international community effectively. However, by now it is evident that the government, with the assistance of the international community and local nongovernmental actors, like major media organisations, has successfully managed the recovery efforts. So, let me begin by thanking them for what they have done so far.
Yet, some may argue that it is not difficult to mobilise the support for recovery efforts from the international community, immediately after any major disaster, and the real challenge is to sustain that support through the next few weeks, months and years. Because the recovery process, more specifically the post-recovery reconstruction process, requires long-term support. So, the government agencies should start immediately to focus on, in addition to initial disaster relief, a longer-term strategy for reconstruction. This is important because in a few weeks’ time, the focus of the global community may shift elsewhere … to another crisis in another corner of the world. Before that happens, the government should take initiatives to get the support from development partners on appropriate policy measures, including exceptional trade preferences, to help Sri Lanka in the recovery efforts through the medium and the long term.
Use of Trade Preferences to support recovery and reconstruction
In the past, the United States and the European Union used exceptional enhanced trade preferences as part of the assistance packages when countries were devastated by natural disasters, similar to Cyclone Ditwah. For example:
- After the devastating floods in Pakistan, in July 2010, the EU granted temporary, exceptional trade preferences to Pakistan (autonomous trade preferences) to aid economic recovery. This measure was a de facto waiver on the standard EU GSP (Generalised Scheme of Preferences) rules. The preferences, which were proposed in October 2010 and were applied until the end of 2013, effectively suspended import duties on 75 types of goods, including textiles and apparel items. The available studies on this waiver indicate that though a significant export hike occurred within a few months after the waiver became effective it did not significantly depress exports by competing countries. Subsequently, Pakistan was granted GSP+ status in 2014.
- Similarly, after the 2015 earthquakes in Nepal, the United States supported Nepal through an extension of unilateral additional preferences, the Nepal Trade Preferences Programme (NTPP). This was a 10-year initiative to grant duty-free access for up to 77 specific Nepali products to aid economic recovery after the 2015 earthquakes. This was also a de facto waiver on the standard US GSP rules.
- Earlier, after Hurricanes Mitch and Georges caused massive devastation across the Caribbean Basin nations, in 1998, severely impacting their economies, the United States proposed a long-term strategy for rebuilding the region that focused on trade enhancement. This resulted in the establishment of the US Caribbean Basin Trade Partnership Act (CBTPA), which was signed into law on 05 October, 2000, as Title II of the Trade and Development Act of 2000. This was a more comprehensive facility than those which were granted to Pakistan and Nepal.

What type of concession should Sri Lanka request from our development partners?
Given these precedents, it is appropriate for Sri Lanka to seek specific trade concessions from the European Union and the United States.
In the European Union, Sri Lanka already benefits from the GSP+ scheme. Under this arrangement Sri Lanka’s exports (theoretically) receive duty-free access into the EU markets. However, in 2023, Sri Lanka’s preference utilisation rate, that is, the ratio of preferential imports to GSP+ eligible imports, stood at 59%. This was significantly below the average utilisation of other GSP beneficiary countries. For example, in 2023, preference utilisation rates for Bangladesh and Pakistan were 90% and 88%, respectively. The main reason for the low utilisation rate of GSP by Sri Lanka is the very strict Rules of Origin requirements for the apparel exports from Sri Lanka. For example, to get GSP benefits, a woven garment from Sri Lanka must be made from fabric that itself had undergone a transformation from yarn to fabric in Sri Lanka or in another qualifying country. However, a similar garment from Bangladesh only requires a single-stage processing (that is, fabric to garment) qualifies for GSP. As a result, less than half of Sri Lanka’s apparel exports to the EU were ineligible for the preferences in 2023.
Sri Lanka should request a relaxation of this strict rule of origin to help economic recovery. As such a concession only covers GSP Rules of Origin only it would impact multilateral trade rules and would not require WTO approval. Hence could be granted immediately by the EU.
United States
Sri Lanka should submit a request to the United States for (a) temporary suspension of the recently introduced 20% additional ad valorem duty and (b) for a programme similar to the Nepal Trade Preferences Programme (NTPP), but designed specifically for Sri Lanka’s needs. As NTPP didn’t require WTO approval, similar concessions also can be granted without difficulty.
Similarly, country-specific requests should be carefully designed and submitted to Japan and other major trading partners.

Lasting power and beauty of words
Novelists, poets, short story writers, lyricists, politicians and columnists use words for different purposes. While some of them use words to inform and elevate us, others use them to bolster their ego. If there was no such thing called words, we cannot even imagine what will happen to us. Whether you like it or not everything rests on words. If the Penal Code does not define a crime and prescribe a punishment, judges will not be able to convict criminals. Even the Constitution of our country is a printed document.
A mother’s lullaby contains snatches of sweet and healing words. The effect is immediate. The baby falls asleep within seconds. A lover’s soft and alluring words go right into his or her beloved. An army commander’s words encourage soldiers to go forward without fear. The British wartime Prime Minister Winston Churchill’s words still ring in our ears: “… we shall defend our Island, whatever the cost may be, we shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender …”
Writers wax eloquent on love. English novelist John Galsworthy wrote: “Love is no hot-house flower, but a wild plant, born of a wet night, born of an hour of sunshine; sprung from wild seed, blown along the road by a wild wind. A wild plant that, when it blooms by chance within the hedge of our gardens, we call a flower; and when it blooms outside we call a weed; but flower or weed, whose scent and colour are always wild.” While living in a world dominated by technology, we often hear a bunch of words that is colourless and often cut to verbal ribbons – “How R U” or “Luv U.” Such words seem to squeeze the life out of language.
Changing medium
Language is a constantly changing medium. New words and forms arrive and old ones die out. Whoever thought that the following Sinhala words would find a place in the Oxford English Dictionary? “Asweddumize, Avurudu, Baila, Kiribath, Kottu Roti, Mallung, Osari, Papare, Walawwa and Watalappan.” With all such borrowed words the English language is expanding and remains beautiful. The language helps us to express subtle ideas clearly and convincingly.
You are judged by the words you use. If you constantly use meaningless little phrases, you will be considered a worthless person. When you read a well-written piece of writing you will note how words jump and laugh on the paper or screen. Some of them wag their tails while others stand back like shy village belles. However, they serve a useful purpose. Words help us to write essays, poems, short stories and novels. If not for the beauty of the language, nobody will read what you write.
If you look at the words meaningfully, you will see some of them tap dancing while others stand to rigid attention. Big or small, all the words you pen form part of the action or part of the narrative. The words you write make your writing readable and exciting. That is why we read our favourite authors again and again.
Editorials
If a marriage is to succeed, partners should respect and love each other. Similarly, if you love words, they will help you to use them intelligently and forcefully. A recent survey in the United States has revealed that only eight per cent of people read the editorial. This is because most editorials are not readable. However, there are some editorials which compel us to read them. Some readers collect such editorials to be read later.
Only a lover of words would notice how some words run smoothly without making a noise. Other words appear to be dancing on the floor. Some words of certain writers are soothing while others set your blood pounding. There is a young monk who is preaching using simple words very effectively. He has a large following of young people addicted to drugs. After listening to his preaching, most of them have given up using illegal drugs. The message is loud and clear. If there is no demand for drugs, nobody will smuggle them into the country.
Some politicians use words so rounded at the edges and softened by wear that they are no longer interesting. The sounds they make are meaningless and listeners get more and more confused. Their expressions are full of expletives the meaning of which is often soiled with careless use of words.
Weather-making
Some words, whether written or spoken, stick like superglue. You will never forget them. William Vergara in his short essay on weather-making says, “Cloud-seeding has touched off one of the most baffling controversies in meteorological history. It has been blamed for or credited with practically all kinds of weather. Some scientists claim seeding can produce floods and hail. Others insist it creates droughts and dissipates clouds. Still others staunchly maintain it has no effect at all. The battle is far from over, but at last one clear conclusion is beginning to emerge: man can change the weather, and he is getting better at it.”
There are words that nurse the ego and heal the heart. The following short paragraph is a good example. S. Radhakrishnan says, “In every religion today we have small minorities who see beyond the horizon of their particular faith, not through religious fellowship is possible, not through the imposition of any one way on the whole but through an all-inclusive recognition that we are all searchers for the truth, pilgrims on the road, that we all aim at the same ethical and spiritual standard.”
There are some words joined together in common phrases. They are so beautiful that they elevate the human race. In the phrase ‘beyond a shadow of doubt’, ‘a shadow’ connotes a dark area covering light. ‘A doubt’ refers to hesitancy in belief. We use such phrases blithely because they are exquisitely beautiful in their structure. The English language is a repository of such miracles of expression that lead to deeper understanding or emphasis.
Social media
Social media use words powerfully. Sometimes they invent new words. Through the social media you can reach millions of viewers without the intervention of the government. Their opinion can stop wars and destroy tyrants. If you use the right words, you can even eliminate poverty to a great extent.
The choice of using powerful words is yours. However, before opening your mouth, tap the computer, unclip a pen, write a lyric or poem, think twice of the effect of your writing. When you talk with a purpose or write with pleasure, you enrich listeners and readers with your marvellous language skills. If you have a command of the language, you will put across your point of view that counts. Always try to find the right words and change the world for a better place for us to live.

Why Sri Lanka Still Has No Doppler Radar – and Who Should Be Held Accountable
Eighteen Years of Delay:
Cyclone Ditwah has come and gone, leaving a trail of extensive damage to the country’s infrastructure, including buildings, roads, bridges, and 70% of the railway network. Thousands of hectares of farming land have been destroyed. Last but not least, nearly 1,000 people have lost their lives, and more than two million people have been displaced. The visuals uploaded to social media platforms graphically convey the widespread destruction Cyclone Ditwah has caused in our country.
The purpose of my article is to highlight, for the benefit of readers and the general public, how a project to establish a Doppler Weather Radar system, conceived in 2007, remains incomplete after 18 years. Despite multiple governments, shifting national priorities, and repeated natural disasters, the project remains incomplete.
Over the years, the National Audit Office, the Committee on Public Accounts (COPA), and several print and electronic media outlets have highlighted this failure. The last was an excellent five-minute broadcast by Maharaja Television Network on their News First broadcast in October 2024 under a series “What Happened to Sri Lanka”
The Agreement Between the Government of Sri Lanka and the World Meteorological Organisation in 2007.
The first formal attempt to establish a Doppler Radar system dates back to a Trust Fund agreement signed on 24 May 2007 between the Government of Sri Lanka (GoSL) and the World Meteorological Organisation (WMO). This agreement intended to modernize Sri Lanka’s meteorological infrastructure and bring the country on par with global early-warning standards.
The World Meteorological Organisation (WMO) is a specialized agency of the United Nations established on March 23, 1950. There are 193 member countries of the WMO, including Sri Lanka. Its primary role is to promote the establishment of a worldwide meteorological observation system and to serve as the authoritative voice on the state and behaviour of the Earth’s atmosphere, its interaction with the oceans, and the resulting climate and water resources.
According to the 2018 Performance Audit Report compiled by the National Audit Office, the GoSL entered into a trust fund agreement with the WMO to install a Doppler Radar System. The report states that USD 2,884,274 was deposited into the WMO bank account in Geneva, from which the Department of Metrology received USD 95,108 and an additional USD 113,046 in deposit interest. There is no mention as to who actually provided the funds. Based on available information, WMO does not fund projects of this magnitude.
The WMO was responsible for procuring the radar equipment, which it awarded on 18th June 2009 to an American company for USD 1,681,017. According to the audit report, a copy of the purchase contract was not available.
Monitoring the agreement’s implementation was assigned to the Ministry of Disaster Management, a signatory to the trust fund agreement. The audit report details the members of the steering committee appointed by designation to oversee the project. It consisted of personnel from the Ministry of Disaster Management, the Departments of Metrology, National Budget, External Resources and the Disaster Management Centre.
The Audit Report highlights failures in the core responsibilities that can be summarized as follows:
· Procurement irregularities—including flawed tender processes and inadequate technical evaluations.
· Poor site selection
—proposed radar sites did not meet elevation or clearance requirements.
· Civil works delays
—towers were incomplete or structurally unsuitable.
· Equipment left unused
—in some cases for years, exposing sensitive components to deterioration.
· Lack of inter-agency coordination
—between the Meteorology Department, Disaster Management Centre, and line ministries.
Some of the mistakes highlighted are incomprehensible. There is a mention that no soil test was carried out before the commencement of the construction of the tower. This led to construction halting after poor soil conditions were identified, requiring a shift of 10 to 15 meters from the original site. This resulted in further delays and cost overruns.
The equipment supplier had identified that construction work undertaken by a local contractor was not of acceptable quality for housing sensitive electronic equipment. No action had been taken to rectify these deficiencies. The audit report states, “It was observed that the delay in constructing the tower and the lack of proper quality were one of the main reasons for the failure of the project”.
In October 2012, when the supplier commenced installation, the work was soon abandoned after the vehicle carrying the heavy crane required to lift the radar equipment crashed down the mountain. The next attempt was made in October 2013, one year later. Although the equipment was installed, the system could not be operationalised because electronic connectivity was not provided (as stated in the audit report).
In 2015, following a UNOPS (United Nations Office for Project Services) inspection, it was determined that the equipment needed to be returned to the supplier because some sensitive electronic devices had been damaged due to long-term disuse, and a further 1.5 years had elapsed by 2017, when the equipment was finally returned to the supplier. In March 2018, the estimated repair cost was USD 1,095,935, which was deemed excessive, and the project was abandoned.
COPA proceedings
The Committee on Public Accounts (COPA) discussed the radar project on August 10, 2023, and several press reports state that the GOSL incurred a loss of Rs. 78 million due to the project’s failure. This, I believe, is the cost of constructing the Tower. It is mentioned that Rs. 402 million had been spent on the radar system, of which Rs. 323 million was drawn from the trust fund established with WMO. It was also highlighted that approximately Rs. 8 million worth of equipment had been stolen and that the Police and the Bribery and Corruption Commission were investigating the matter.
JICA support and project stagnation
Despite the project’s failure with WMO, the Japan International Cooperation Agency (JICA) entered into an agreement with GOSL on June 30, 2017 to install two Doppler Radar Systems in Puttalam and Pottuvil. JICA has pledged 2.5 billion Japanese yen (LKR 3.4 billion at the time) as a grant. It was envisaged that the project would be completed in 2021.
Once again, the perennial delays that afflict the GOSL and bureaucracy have resulted in the groundbreaking ceremony being held only in December 2024. The delay is attributed to the COVID-19 pandemic and Sri Lanka’s economic crisis.
The seven-year delay between the signing of the agreement and project commencement has led to significant cost increases, forcing JICA to limit the project to installing only one Doppler Radar system in Puttalam.
Impact of the missing radar during Ditwah
As I am not a meteorologist and do not wish to make a judgment on this, I have decided to include the statement issued by JICA after the groundbreaking ceremony on December 24, 2024.
“In partnership with the Department of Meteorology (DoM), JICA is spearheading the establishment of the Doppler Weather Radar Network in the Puttalam district, which can realize accurate weather observation and weather prediction based on the collected data by the radar. This initiative is a significant step in strengthening Sri Lanka’s improving its climate resilience including not only reducing risks of floods, landslides, and drought but also agriculture and fishery“.
Based on online research, a Doppler Weather Radar system is designed to observe weather systems in real time. While the technical details are complex, the system essentially provides localized, uptotheminute information on rainfall patterns, storm movements, and approaching severe weather. Countries worldwide rely on such systems to issue timely alerts for monsoons, tropical depressions, and cyclones. It is reported that India has invested in 30 Doppler radar systems, which have helped minimize the loss of life.
Without radar, Sri Lanka must rely primarily on satellite imagery and foreign meteorological centres, which cannot capture the finescale, rapidly changing weather patterns that often cause localized disasters here.
The general consensus is that, while no single system can prevent natural disasters, an operational Doppler Radar almost certainly would have strengthened Sri Lanka’s preparedness and reduced the extent of damage and loss.
Conclusion
Sri Lanka’s inability to commission a Doppler Radar system, despite nearly two decades of attempts, represents one of the most significant governance failures in the country’s disastermanagement history.
Audit findings, parliamentary oversight proceedings, and donor records all confirm the same troubling truth: Sri Lanka has spent public money, signed international agreements, received foreign assistance, and still has no operational radar. This raises a critical question: should those responsible for this prolonged failure be held legally accountable?
Now may not be the time to determine the extent to which the current government and bureaucrats failed the people. I believe an independent commission comprising foreign experts in disaster management from India and Japan should be appointed, maybe in six months, to identify failures in managing Cyclone Ditwah.
However, those who governed the country from 2007 to 2024 should be held accountable for their failures, and legal action should be pursued against the politicians and bureaucrats responsible for disaster management for their failure to implement the 2007 project with the WMO successfully.
Sri Lanka cannot afford another 18 years of delay. The time for action, transparency, and responsibility has arrived.
