The Silent Shadow: The threat of the Nipah virus in Asia

Published

on

In the quiet woods of West Bengal and the lush countryside of Kerala, a lethal pathogen is once again testing the limits of modern biosafety. The Nipah virus (NiV), a shadow that has flickered across South and South-East Asia for decades, is currently the subject of heightened international surveillance. With a case fatality rate that can soar up to 75%, this virus Nipah is not just a regional concern; it is a priority pathogen on the World Health Organization (WHO) Research and Development Blueprint, alongside Ebola and COVID-19, due to its epidemic potential.

To understand the much-justified fear Nipah inspires in the scientific community, one needs to look at its molecular machinery. Nipah is a negative-sense, single-stranded RNA virus belonging to the genus Henipavirus. In a kind of “Instruction Manual” analogy, Positive-Sense (+RNA) arrive with an instruction manual already written in the cell’s language. As soon as they enter the cell, the cell can start reading the RNA and “printing” viral proteins immediately. In contrast, Negative-Sense (-RNA) viruses like Nipah, Influenza, or Rabies, arrive with an instruction manual that is written backwards or as a “mirror image.” The cell’s machinery cannot read it directly. It cannot dictate terms to the cell. It needs a “translator” to get the cell to do what the virus wants. If the translator is deactivated, the virus becomes inert. However, with the help of the active translator, a replication pathway is created. This specific replication pathway is a major area of study for antiviral drugs. If we can find a way to “jam” that specific viral translator without hurting the host cell’s own functions, we can effectively stop the virus, so to speak, in its tracks.

Nipah is a “Biosafety Level 4” agent; the highest risk category requiring maximum containment. The virus targets the host’s cells lining of blood vessels and the nerve tissues. Once it enters the human body, typically through the binding of its attaching glycoprotein to host receptors, it initiates a devastating cascade. The infection often presents as a dual-threat, namely acute respiratory problems with features of severe “atypical pneumonia,” and potentially fatal involvement of the brain. In its most sinister form, the virus crosses the blood-brain barrier which routinely protects against invasion of the central nervous system by infective organisms, causing massive inflammation of the brain. Symptoms progress rapidly from fever and headache to drowsiness, disorientation, and seizures, often culminating in a coma within 24 to 48 hours.

As of January 2026, the epidemiological map of Asia shows several distinct hotspots. India is currently managing two distinct geographical risks. In West Bengal, a recent cluster in Kolkata and Barasat involving healthcare workers has triggered a massive “trace and test” operation. This region, bordering Bangladesh, has a history of outbreaks dating back to 2001. Simultaneously, Kerala in Southern India has become a recurrent epicentre, with four confirmed cases and two deaths reported in mid-2025 across the Malappuram and Palakkad districts.

Bangladesh remains the most consistently affected nation. In 2025 alone, four fatal, unrelated cases were reported across the Barisal, Dhaka, and Rajshahi divisions. Unlike the hospital-based transmission often seen elsewhere, Bangladesh’s outbreaks are frequently linked to a cultural staple, which is the consumption of raw date palm sap.

The current clusters have sent warning currents across the continent. Airports in Thailand (Suvarnabhumi and Phuket), Nepal, and Singapore have reinstated COVID-style health screenings for travellers arriving from affected Indian states. Taiwan has gone a step further, proposing to categorise Nipah as a “Category 5” notifiable disease; the highest level of public health alert.

The natural reservoir of Nipah is the Pteropus genus of fruit bats, commonly known as flying foxes. These bats carry the virus without falling ill themselves, shedding it in their saliva, urine, and excrement. The “spillover” to humans typically occurs via three routes:

= Contaminated Food: Eating fruit partially consumed by bats or drinking raw date palm sap where bats have urinated into the collection pots.

= Intermediate Hosts: In the 1998 Malaysia outbreak, pigs acted as “amplifying hosts” after eating contaminated fruit, later passing the virus to farmworkers.

= Human-to-Human: This is the greatest concern for urban centres. Close contact with the bodily fluids or respiratory droplets of an infected patient, often enough in a home care or hospital setting, can trigger secondary clusters.

While Sri Lanka has not yet recorded a human case of Nipah, the island cannot afford complacency. The risks are grounded in both biology and regional connectivity. Surveillance studies have confirmed that Pteropus bat species are indigenous to Sri Lanka. While the presence of the bat does not guarantee the presence of the virus, the ecological apparatus for a spillover event exists on the island. Environmental changes, such as deforestation, can drive these bats closer to human settlements in search of food, increasing the probability of contact.

Sri Lanka’s proximity to South India, particularly Kerala and Tamil Nadu, creates a constant flow of people and goods. With direct flights and maritime links to regions currently monitoring outbreaks, the risk of an “imported case” is quite considerable. A single undetected traveller in the incubation period, that is the period between the infection and production of the disease, which can last from 4 to 14 days, and in rare cases up to 45, could theoretically introduce the virus into a local clinical setting.

The primary challenge for Sri Lanka lies in looking at what doctors call a “differential diagnosis”, which looks at all possible conditions that have a similar clinical presentation. Early symptoms of Nipah mimic common tropical illnesses like dengue, Japanese encephalitis, or even severe influenza. Without high-level biocontainment labs (BSL-3 or BSL-4) and rapid Polymerase Chain Reaction (PCR) testing protocols specifically tuned for Henipaviruses, a localised outbreak could gain significant momentum before it is correctly identified. Incidentally, PCR is a sort of molecular photocopier which allows scientists to take a tiny, almost undetectable amount of viral genetic material (RNA or DNA) from a patient’s swab or blood sample and amplify it millions of times until there is enough to be detected and identified.

Currently, there is no licensed vaccine or specific antiviral drug in the treatment for Nipah. Management is limited to intensive supportive care. However, the “One Health” approach offers a roadmap for prevention:

=For the Public: Ensure all fruits are thoroughly washed and peeled, and discard any fruit that shows signs of bird or animal bites (“bat-bitten” fruit).

=For Healthcare Workers: Strict adherence to Infection Prevention and Control (IPC) measures. Wearing personal protective equipment (PPE) when treating patients with unexplained encephalitis or respiratory distress is vital.

=For Authorities: Strengthening surveillance of bat populations and enhancing the diagnostic capacity of national laboratories.

Nipah virus is a reminder of the permeable borders between the wild and the urban. As Asia watches the current clusters in India and Bangladesh, the lesson for Sri Lanka is clear: preparedness is the only antidote to a virus that currently has no cure.

We need to make the general public well aware of preventive guidelines for travellers to other countries, most particularly for those traveling to or from Kerala, West Bengal, or Bangladesh. Before travel, it is necessary to monitor the Sri Lankan Ministry of Health (Epidemiology Unit) website for travel advisories. Currently, screening is focused on passengers arriving from Kolkata and Kerala. It is essential to ensure that travel insurance covers medical evacuation and high-intensity supportive care, as Nipah management requires ICU facilities.

During the stay in an area of another country that is a high-risk area, avoid “Bat-Bitten” Fruit and do not purchase or consume fruit that has visible puncture marks, scratches, or missing chunks. In regions where fruit bats (Pteropus) are active, they often taste fruit and discard it, leaving saliva and virus behind. It is essential to only eat fruit that you have washed thoroughly with clean water and peeled yourself. Avoid pre-sliced fruit platters in street markets. Stay away from pig farms and bat roosting sites such as large trees where “flying foxes” gather. If you visit rural areas, do not touch surfaces under these trees which may be contaminated with bat urine.

Once a traveller returns to Sri Lanka, the authorities at the ports of entry have to be most vigilant. As for the traveller, it is best to self-monitor for about a month. The incubation period can be long. If you develop a fever, severe headache, or cough within three weeks of returning, isolate yourself immediately. If you seek medical care, the very first thing you should tell the doctor is: “I have recently returned from a region where Nipah cases were reported.”

Healthcare workers have to be extremely careful. This is crucial for doctors and nurses in Sri Lankan Outpatient Departments (OPD) and Emergency Treatment Units (ETUs). Careful medical triage of sorting out possible cases is mandatory. It is necessary to maintain a High Index of Suspicion: In any patient presenting with Acute Respiratory Distress Syndrome (ARDS) or Encephalitis (confusion, seizures, or coma), immediately check their travel history or contact with travellers. It is essential that the health staff do not rule out Nipah just because a patient has a “simple” cough or a “sore throat” as these often precede the neurological crash by 24–48 hours.

Infection Prevention and Control (IPC) measures have to be employed compulsorily. Because Nipah has a high rate of nosocomial (hospital-acquired) spread, the following “Standard Plus” precautions are mandatory for suspected cases:-

=Meticulous hand hygiene before and after patient contact.

=Use of medical masks and eye protection (goggles or face shields).

=Double gloving and the use of fluid-resistant gowns.

If a patient is suspected to suffer from Nipah virus infection, the patient needs to be moved to a dedicated isolation ward immediately. Do not “cohort” (group) them with other encephalitis or flu patients until Nipah is ruled out by PCR. Treat all bodily fluids (blood, urine, saliva) as highly infectious biohazards. Use 0.5% sodium hypochlorite for surface disinfection. Under the Infectious Diseases Act, Nipah is a notifiable disease in Sri Lanka. Contact the regional Medical Officer of Health (MOH) or the Epidemiology Unit immediately upon suspicion. DO NOT WAIT FOR LAB CONFIRMATION.

One final but absolutely vital and life-saving declaration and truism is that the Nipah virus is very sensitive to common soaps and detergents. Regular handwashing with soap for at least 20 seconds is one of the most effective ways to break the chain of transmission, even for a virus that is this lethal.

Trump’s tariffs, AKD’s gazette and Sri Lanka’s diplomatic slumber

Published

on

“We are rather respectable in Colombo. We go to bed fairly early, and we remain there till morning. “

According to Sri Lanka’s diplomatic folklore, the late S.W. R. D. Bandaranaike uttered these words while explaining the reasons for Sri Lanka’s abstention on the UN resolution condemning the Soviet invasion of Hungary. Apparently, SWRD’s foreign ministry officials were asleep at home when the diplomatic cable seeking instructions was received from New York. In those days, there were no cell phones, Internet, or even fax or telex machines. The diplomatic cables were sent through post offices. Decoding them was a slow and time-consuming process. Thus, the government could not provide appropriate instructions to our mission in New York in time, and the Sri Lankan delegation abstained on that sensitive UN vote.

Sri Lanka’s Absence from Section 301 Consultations

But then, how does one explain Sri Lanka’s absence from the crucial bilateral consultation held in Washington by the Office of the United States Trade Representative (USTR) during March-April on “Forced Labour” under the Section 301 of the US Trade Act of 1974? Didn’t our foreign and trade ministries send appropriate instructions to Washington in time? Even if the instructions from the foreign ministry were transmitted to our embassy in Washington by pigeon carriers, there was enough time for Sri Lanka to participate in those meetings.

In March, the USTR initiated these 301 investigations on 60 trading partners, and invited all of them for confidential consultations. Out of the 60, 46 participated in these consultations. Sri Lanka was not one of them. Other countries that didn’t participate in these consultations included China, Russia, and Venezuela! In addition to that, the Section 301 Committee conducted a public hearing with interested parties on April 28 and 29. Washington-based diplomats, representatives from few trade ministries as well as representatives from many foreign trade associations and chambers participated in these hearings. Sri Lanka was once again conspicuously absent.

As a result, when the USTR published the proposed forced labour tariffs on June 2nd, Sri Lanka ended up with a 12.5% duty. Pakistani and Indonesian diplomats participated in these consultations and took appropriate follow-up measures, and managed to enter the 10% duty category. As even a threat of a modest tariff hike could disrupt supply chains and reduce competitiveness, particularly in an industry such as garments, I discussed this issue on 15 June and underscored the importance of Sri Lanka’s participation at the next hearing, which was scheduled to be held from July 7th .

Awakening from Diplomatic Slumber and AKD’s Gazette

Fortunately, Sri Lanka finally awoke from weeks of diplomatic slumber, and Ambassador Mahinda Samarasinghe participated in the public hearing on 9 July, and promised, “…. · We have agreed to the text in our negotiations with the USTR on forced labour, …. The gazette as we speak is being printed and I’m getting the gazette tomorrow morning, and the gazette will be shared with USTR as I get it“.

As promised, President Anura Kumara Dissanayake issued a gazette on 10 July banning the imports of goods produced by forced labour. These new regulations are very similar to what Pakistan and Indonesia enacted in April, after their consultations with USTR in March. Why couldn’t we do it in April? Why did we wait till the very last minute?

Challenges ahead

“War is too important to be left to generals alone,” is a famous saying attributed to former French Premier Georges Clemenceau. Similarly, monitoring our main markets is too important to be left to diplomats alone. The United States is the largest single-country market for Sri Lanka. Therefore, Sri Lankan trade chambers and associations should become more proactive in these markets and participate in these events. For example, the chairman of the Pakistani apparel exporters association participated in the April hearings. Similarly, representatives from the Indian Agricultural and Processed Food Products Export Development Authority, the Federation of Indian Chambers of Commerce and Industry, the Confederation of Indian Industry, and Reliance Industries also participated in July hearings. At an event where each speaker is given only five minutes (strictly enforced), having a number of speakers from a country is an advantage. The presence of industry representatives in these kinds of events also help them understand the market dynamics and the future challenges. This is important, particularly because there will be many more challenges with Trump’s tariffs.

With the gazette issued on 10 July, Sri Lanka has imposed a prohibition on the importation of goods produced with forced labour. Now, the challenge will be to effectively enforce the prohibition. And what are the goods produced with forced labour? The USTR list only focuses on aluminum, cotton, electronics, lithium-ion batteries, rice, and tobacco. However, according to the U.S. Department of Labour, the list is much longer. Hence, this list may change continuously during the next two years and tariffs may fluctuate once again.

So, this is definitely not the time to slumber.

Tales of Mystery and Suspense 10 Casino for Sale

Published

on

After the overwhelming grotesquerie of J K Rowling’s latest Cormoran Strike novel (written, I should have noted, as the others were, under the pseudonym Robert Galbraith), I thought I should return to the world of fun, and also a much shorter description since this thriller moves quickly without the layers of detail that Rowling engages in.

I then move to the second comic thriller by Caryl Brahms and S J Simon. This, their second story to feature Vladimir Stroganoff and Adam Quill, was Casino for Sale, as lunatic a romp as the first, though without the emphasis on the ballet that characterized A Bullet in the Ballet.

This one begins with the impresario Stroganoff buying a casino cheap from Baron Sam de Rabinovich, only to find that it was a rundown place, not the grand casino of La Bazouche, a resort on the Frenc+h Riviera, as he had initially thought. The grand one belonged to Lord Buttonhooke, and Stroganoff could  not compete, until he thought of bringing the Ballet Stroganoff to the casino – which of course leads to Buttonhooke deciding to have ballet performances in his Casino too.

Stroganoff invites Quill to visit him, which Quill decides to do since he has left Scotland Yard, having come into a legacy. No one believes this, and he has to face questions as to what he did to have been sacked, with sympathy for having been found out.

Caryl and Simon

The day he arrives in La Bazouche there is a murder, of a vitriolic critic called Citrolo, in Stroganoff’s office. He had been going to write a damning review of the opening night of the ballet and Stroganoff, when he realizes Citrolo cannot be swayed, drugs him and dictates the review himself to the papers. He leaves Citrolo sleeping and finds him shot the next morning, whereupon he decides to muddy the waters and leave a suicide note and lots of other murder weapons. So much overkill, as it were, of course ensures that he is arrested.

But the excitable French detective who makes the arrest follows up his suggestion that Buttonhooke was also involved, and so the two casino owners find themselves in cells next door to each other, with the detective Gustave quite happy to provide creature comforts for a fee.

Quill decides he must investigate, and finds Gustave most cooperative, since he has a laid back attitude to work. So it is Quill that finds a notebook which makes it clear Citrolo is an accomplished blackmailer, and that there are lots of possible murderers, including Stroganoff’s croupier, who was crooked, Rabinovich, who was now working for Buttonhooke, a confidence trickster called Kurt Kukumber, whose prospectus for a dud gold mine was found in the office and Prince Alexis Artishok who was engaged in a deal to buy diamonds from the ballerina Dyra Dyrakova.

Stroganoff had been trying to get Dyrakova to dance for him, but having done so previously she had refused. But then to Stroganoff’s chagrin she agreed to dance for Buttonhooke. The clearly crooked Artishok had told Buttonhooke’s mistress Sadie Souse, who was not very bright, that Dyrakova possessed diamonds she was willing to sell cheap, and Sadie was determined to have them.

Quill meanwhile finds out that there was a secret passage to Stroganoff’s office, the obvious solution to what had begun as a locked room mystery, and that this was known by almost everyone apart from Stroganoff himself. And then Rabinovich is murdered, just after Gustave had released his two original suspects, leading him to blame Quill for having insisted on that and thus allowing them to kill again.

Soon afterwards Dyrakova arrives, and the town is full of posters announcing that she will appear in the casinos, elaborate posters for either one, since Stroganoff is determined that she will dance for him, and if she does not come willingly, he has devised a scheme to make her do so unwillingly. So, though Buttonhooke has her taken off to his yacht immediately she arrives at the station, Quill along with Arenskaya gets her into a launch and to Stroganoff’s casino, where she performs to tumultuous applause, not knowing for whom she is dancing.

When Quill asked her about the diamonds, she said she had sold them long ago, and that gave Quill the solution to the mystery. Rabinovich had known about this, and Artishok had killed him to prevent Sadie learning it from him, he had killed Citrolo who had recognized him for an accomplished card sharper, not a Russian prince at all. But before he is arrested, he gets away in a boat, and the police launch that pursues him is on the point of catching him up when it runs out of petrol.

Again, lots of excitement, and entertaining references  – Gustave grows marrows – and if not quite as brilliant as its predecessor, Casino was certainly a delightful read.

The challenge of being positive about SAARC

Published

on

The RCSS forum addressed by SAARC Secretary General Ambassador Md. Golam Sarwar in progress. (Pic courtesy RCSS)

It was a few years back that a former President of Sri Lanka took it on himself to pronounce SAARC ‘dead’. Since then there have been other sections of Sri Lankan opinion that have joined the critics of SAARC and taken the solemn stance that SAARC has indeed died what may be called a natural death.

Their fatalism is understandable. SAARC has failed to meet at heads of government or state level for the past several years to take the SAARC process notably forward. Regional cooperation has more or less been only an appealing idea. No substantive concrete projects have taken off to make the idea a hard reality. ‘Inner paralysis’ seems to be SAARC’s lot. Hence the fatalism in these circles.

However, being one of the worst cash-strapped regions of the world and a teemingly populated one with people virtually left to their devices, what choices do the ‘SAARC Eight’ have other than to try their best to band together and continue with their cooperation efforts, however small they may be?

There is no escaping the mounting debt trap for many of these countries and bankrupt Sri Lanka is a glaring example, but ‘throwing in the towel’ and abandoning themselves entirely to the diktats of the strongest economies and their agencies will prove a ‘living death’ for many countries in the SAARC fold.

The gains may be meagre but giving-up on SAARC cooperation in full would prove self-defeating for the organization and South Asia. Right now, the collective intention ought to be to salvage what the region could from the tenuous cooperative efforts. Moreover, such initiatives could go some distance to generate a degree of goodwill among the Eight and help in sustaining a dialogue process.

Given this backdrop it proved ‘a stich in time’ for the Regional Centre for Strategic Studies (RCSS), Colombo, to recently host the SAARC Secretary General Ambassador Md. Golam Sarwar to a round table discussion on the unifying potential of SAARC and its future possibilities, besides other related issue areas.

Held on June 24th and moderated by RCSS Executive Director and former ambassador Ravinatha Aryasinha, the forum brought together a vibrant, wide ranging audience comprising academicians, diplomats, senior public servants, civil society activists and many others. Following the presentation by Ambassador Golam Sarwar titled, ‘Reigniting SAARC: Achievements, Challenges and the Way Ahead’, a lively Q&A followed.

The above forum could be described as an act of lighting the proverbial ‘candle’ rather than ‘cursing the darkness.’ It surely is a ‘darkness’ that could be seen as daunting considering that the region’s pivotal powers, India and Pakistan, are failing to act in a spirit of accord but are engaged in bitter finger-pointing on a number of questions of vital importance to SAARC.

On the other hand, what is the rest of the region doing to bring the above sides together? It is disappointing that to date the rest of SAARC has failed to launch a major diplomatic drive to bring peace between the feuding regional heavyweights. It needs to act without delay and establish its earnestness and this effort would need to prove SAARC’s staying power in the unfolding months and even years.

In assessing SAARC’s seeming failure local opinion in particular has failed to factor in what could be described as weak leadership. Since Sheikh Mujibur Rahman of Bangladesh, the founding father of SAARC, the region has failed to produce a visionary leader who could advance the SAARC cause with charisma and drive.

Among other reasons, weak leadership accounts considerably for the faltering and stuttering status, as it were, of SAARC. Badly needed are leaders who could go the extra mile, think less of narrow national interests and work diligently towards the collective well being of the region but SAARC’s millions of ordinary people have been made to wait in vain for leaders of such stature. Instead, they have been burdened with politicians who seem to be relishing the apparently moribund state of SAARC.

Looking back, it could be said that it was the dynamic leadership factor that led to the launching of the Non-Aligned Movement and for its sustenance for a few decades. True, it could be seen in some quarters that NAM is no more, but as in the case of SAARC, the former too has been unfortunate to be burdened over the years with politicians who lack the vision and drive to unflaggingly advance the fortunes of the South. NAM and SAARC lack the dynamism and vision of leaders of the stature of Jawaharlal Nehru, for example, to give them the required guidance and intellectual depth.

The reasons are complex for there not being among us currently political leaders with the vision and the steadfast commitment to advance the legitimate interests of the South. However, it could be stated with conviction that the majority of Southern leaders have too easily caved in to the demands of the global North and its financial agencies.

These leaders have failed to see, for instance, that the largely market economy oriented Northern governments would not view with favour a centrist economic model that attaches priority to the interests of the dis-empowered publics of the South. This realization ought to have dawned on the current government in Sri Lanka, for instance, some while ago but it has no choice but to abide by IMF dictates since economic survival at present is unthinkable without the latter’s succour.

Accordingly for SAARC this should be the time for some soul-searching. Priority needs to be attached to ending the feuding between India and Pakistan since at present the material fortunes of the region hinge largely on these regional giants giving peaceful relations among them a try. This is no easy challenge to meet but some daring, visionary diplomacy needs to take hold among the rest of SAARC.

There is some sense in SAARC bringing the peoples of the region together through programs that address their best collective interests. A meeting of minds among SAARC nations could enable SAARC and its agencies to build a region-wide people’s movement for progressive political and economic change that could in turn lead to the region’s political leaders sensitizing themselves more to the neglected needs of their publics.

However, the time is ‘now’ for the initiation of these progressive changes and the voice of SAARC well wishers would need to drown out those of their critics.
