Philippines confirms first case of H5N9 bird flu
MANILA: The Philippines has detected its first case of the H5N9 strain of bird flu, according to a report released Wednesday (May 7) by the Bureau of Animal Industry (BAI). The infection was found in ducks from Camaligan, Camarines Sur, marking the latest strain of avian influenza to reach the country.
The Department of Agriculture (DA), which oversees the BAI, confirmed that laboratory tests showed positive results for the highly pathogenic Type A Subtype H5N9 virus. Although the strain is known to spread rapidly and cause severe illness in birds, the DA stated that it poses only a low risk to humans unless there is prolonged and repeated exposure.
First identified in the United States earlier this year, the H5N9 virus is believed to be a mutation of previously circulating bird flu strains. In the Philippines, local livestock have already been affected by other variants, including H5N1, H5N2, and H5N6.
The last recorded outbreak occurred in January and involved the H5N2 strain in Camarines Norte, affecting 15 out of 428 backyard ducks, according to the World Organisation for Animal Health.
In response to the latest case, the BAI has rolled out immediate containment efforts in the Bicol Region. These include quarantine enforcement, culling of infected birds, heightened surveillance, and coordination with local government units and the Department of Health to monitor for any possible human transmission.
The DA added that extended disease control measures are being carried out within a 1-kilometre and a 7-kilometre radius of the outbreak site. These include thorough cleaning and disinfection to curb further spread of the virus.
As of April 25, avian influenza continues to affect four regions and eight provinces, including Kalinga, Benguet, Pampanga, Nueva Ecija, Tarlac, Bataan, Bulacan, Laguna, and Manila.

Sabah's silent health threat
KOTA KINABALU: Sabah could face the next major infectious disease outbreak if nothing is done to strengthen biosurveillance and reduce human-wildlife contact, according to an expert. Universiti Malaysia Sabah (UMS) Biotechnology Research Institute researcher Prof Dr Vijay Kumar said the state's environmental richness was its strength and also its greatest vulnerability with emerging infectious diseases. He said Sabah's natural wealth was extraordinary, but that same biodiversity made it a hotspot for potential disease spillovers. 'We're seeing more pathogens jump from animals to humans – not just in isolated cases, but across multiple fronts. From zoonotic malaria to emerging coronaviruses and outbreaks in livestock, the risks are real, growing, and deeply concerning. 'We cannot afford to be complacent. Every delay in surveillance and every missed opportunity to act early increases the risk of another major outbreak – one that can cripple our healthcare system, disrupt livelihoods and damage Sabah's reputation as a biodiversity haven,' he added in a statement yesterday. Prof Vijay said the rising threats underscored the importance of adopting the One Health approach, which integrated human, animal and environmental health to tackle zoonotic diseases in a coordinated and proactive way. Sabah is seeing a rise in diseases that can jump from animals to humans, like malaria from macaques, coronaviruses from bats, diseases in poultry, and infections from rodents, mainly because people are moving into natural areas more. He highlighted the danger posed by the plasmodium knowlesi, a malaria parasite spread from macaques via mosquitoes, which formed the bulk of malaria cases in the state. Prof Vijay said researchers have also discovered several new coronaviruses in bat populations, on the back of the SARS and Covid-19 global outbreaks. Infectious disease risks also extend to the agricultural sector, as evidenced by the 2018 outbreak of H5N1 avian influenza in the state, which led to the culling of thousands of poultry. 'While no human cases were confirmed, antibodies detected in individuals pointed to previous exposure. 'Other poultry diseases, such as the Newcastle Disease Virus and Infectious Bronchitis Virus, continue to challenge farmers as local strains render existing vaccines less effective,' he added. Sabah's animal health concerns are not limited to land-based species. In the waters around Mabul Island, rising cases of sea turtle fibropapillomatosis, a tumour-causing herpesvirus, are threatening endangered marine life. Prof Vijay said African Swine Fever has decimated both wild and farmed pig populations, disrupting ecosystems and affecting traditional hunting in indigenous communities. 'Urban and environmental threats are just as pressing. Soil- and water-borne infections such as melioidosis and leptospirosis remain endemic in Sabah, while rats in urban centres have been found carrying bartonella bacteria, posing a largely unnoticed risk to city dwellers,' he added. Prof Vijay noted that many of these risks arise from unregulated human activities. 'Poaching, illegal wildlife trade, agricultural expansion, and deforestation are increasing our contact with animals that may carry unknown pathogens,' he stated. He cautioned that large-scale development projects like Indonesia's new capital Nusantara in East Kalimantan may further fragment Borneo's ecosystems, intensifying human-wildlife conflict and accelerating the spread of new diseases. To counter these threats, Prof Vijay and his colleague Assoc Prof Dr Zarina Amin called for a stronger One Health framework to, among others, enhance genomic surveillance, incorporate AI to detect emerging pathogens early and increase awareness among the rural and indigenous communities. They also recommended promoting conservation-focused land-use policies to reduce ecological disruptions, and they urged the government to prioritise long-term investment in biosurveillance. 'Investing in biosurveillance is no longer optional. It's essential if we want to protect not only public health but also Sabah's economy, food security and conservation efforts,' Prof Vijay said. He also called for the formation of an interdisciplinary task force to unite virologists, conservationists, AI specialists, public health experts and policymakers to drive One Health collaboration in the state.

New task force needed to monitor animal-to-human disease risks, say experts
KOTA KINABALU: Experts from Universiti Malaysia Sabah (UMS) have called for the formation of an interdisciplinary task force to address the growing threat of zoonotic diseases in Borneo. They said the task force should include representatives from government agencies, academic institutions and conservation bodies. In a joint statement, UMS Biotechnology Research Institute's Professor Dr Vijay Kumar and Associate Professor Dr Zarina Amin said that while Borneo's biodiversity is unparalleled, increasing infrastructural development has raised the risk of zoonotic spillovers - where pathogens jump from animals to humans. "In Sabah, where human-wildlife interactions are frequent, biosurveillance must remain a priority. "The spread of infectious diseases not only threatens public health, but also tourism, agriculture and conservation efforts." A well-documented example is Plasmodium knowlesi malaria, transmitted from macaques to humans by mosquitoes. In addition, several previously unknown coronaviruses - similar to SARS and COVID-19 - have been detected in bats in Sabah, highlighting the risks faced by tourists and locals visiting bat-inhabited caves. Sabah's poultry farms have also experienced outbreaks of highly pathogenic avian influenza (H5N1) in 2018, while neighbouring Sarawak continues to battle rabies, which accounts for nearly all reported cases in Malaysia. Livestock and wildlife diseases are an increasing concern. Strains of Newcastle Disease Virus and Infectious Bronchitis Virus have impacted Sabah's poultry industry, while African Swine Fever has devastated wild and farmed pig populations. Marine wildlife is not spared either. On Mabul Island and surrounding waters, an increasing number of sea turtles are suffering from fibropapillomatosis, a herpesvirus-linked disease. Melioidosis, which thrives in Sabah's tropical soil, has infected humans and wildlife - including orangutans and macaques. Leptospirosis also remains a persistent threat. "Looking ahead, large-scale developments such as Indonesia's new capital, Nusantara, in East Kalimantan could significantly disrupt Borneo's ecosystems. "Increased deforestation, agricultural expansion, and hydropower projects will likely escalate human-wildlife conflict, habitat loss and disease spillovers." The experts urged for a strengthened One Health approach, combining genomic surveillance, AI analytics, public education, enforcement against poaching, sustainable land-use policies, and better policy integration and funding.

Trump's WHO withdrawal could cost the US dearly
While the Covid-19 pandemic is firmly in the past for many Americans, US households continue to bear the costs of infectious-disease outbreaks. A few months ago, the price of eggs in the US soared to a record high, largely owing to the spread of H5N1 bird flu. Since March 2024, the virus has ravaged US chicken farms, leading to tens of millions of poultry deaths from infection or culling. More ominously, at least 70 human cases of bird flu have been identified in the US, with one death reported in Louisiana. In a recent report about enhancing the response to H5N1 in America and globally, the Global Virus Network, a consortium of the world's top virologists, warned of 'the terrible consequences of underreacting to current threats'. But while bird flu poses the most immediate risk to Americans, it is by no means the only one. Virulent infectious-disease outbreaks in other countries, such as mpox in the Democratic Republic of the Congo, Ebola in Uganda, Marburg in Tanzania, and multi-country outbreaks of cholera, do not respect borders, and thus are a threat to people everywhere – including in the US. Without the efforts of the World Health Organization (WHO) to contain these outbreaks, the risk of wider transmission would be much greater. This underscores the need for a global agency like WHO to supervise cross-border cooperation – and the shortsightedness of President Donald Trump's decision to withdraw the US from the organisation. Despite being the world's richest and most powerful country, America is not immune to another Covid-style calamity, and abandoning multilateralism and neglecting pandemic preparedness (such as the stockpiling of treatments and vaccines) will make it all the more vulnerable. One might think that the deadly spread of Covid-19, prolonged by the emergence of new virus strains, would convince policymakers to strengthen the world's public-health architecture – especially as experts warn that future pandemics could be even worse. But with other leaders indicating that they may follow Trump's example and leave WHO, the resources for pandemic prevention and control could dwindle to the point that global outbreaks become more frequent and difficult to overcome. If Trump follows through with the move, his administration will become increasingly isolated and impotent. American officials, including at US military installations abroad, will lose access to WHO-led and -facilitated global networks that collect and share information about infectious-disease threats and respond to outbreaks. Moreover, the US government will have no say in developing new solutions (which will almost invariably be less effective) for controlling the spread of diseases across borders – including its own. Trump has suggested that he may change his mind, presumably if the grievances set out in his executive order to withdraw the US from the organisation are addressed. This implies that WHO should apply pressure on China to identify the pandemic's origins. WHO director-general Tedros Adhanom Ghebreyesus, for his part, has refused to accept the Chinese government's prevarications. If Trump can propose a way to determine the cause of Covid-19, I am sure that WHO's leadership would gladly hear it. Trump's second condition is that WHO undertakes reforms and uses its resources more effectively at the local level, with a greater focus on stopping the spread of infectious diseases. This is a demand that can and should be met. To that end, Tedros has already promised more targeted use of funds and implemented other measures to transform the organisation. In addition, under Tedros, WHO has transformed the way it raises funds. Its member states have sharply increased their annual contributions, and it has diversified its donor base to share the funding load more widely. This is all part of WHO's drive to be more sustainably financed, a plan launched as part of Tedros's effort to transform the organisation's operations after he took office in 2017. Back then, he and member states assessed that the departure of a major donor could leave WHO's programmes and independence vulnerable to funding shocks. Who knew it would be the US. But, had those changes not been made, we can only imagine how much more challenging WHO's current financial situation would be. The Trump administration should welcome these changes, not least because it benefits from having a seat at the table. If the US ultimately abandons WHO, developing evidence-based guidance and regulations for chronic-disease prevention and management will be significantly harder, undermining the administration's goal of addressing America's chronic-disease epidemic. The US will also no longer be a part of WHO's medicine prequalification process, a programme that opens a host of new markets for drug producers in a cost-effective manner. Instead, US pharmaceutical companies will be forced to sell their prequalified products to each country individually, putting them at risk of losing access to highly profitable multibillion-dollar markets. Twenty-first-century trends – including more mobility and international travel, greater urbanisation, and increasing human encroachment on nature – fuel the global spread of infectious diseases, to the detriment of everyone. US officials would be better positioned to protect their citizens if they joined – and perhaps even led – a discussion on how WHO and other global health organisations, such as Gavi, the Vaccine Alliance, and the Global Fund to Fight AIDS, Tuberculosis, and Malaria, can meet the world's needs. One such initiative, in which the US had been a strong partner until Trump took office, was to negotiate a WHO Pandemic Agreement, which was adopted by consensus by WHO member states at the World Health Assembly on May 20. This historic compact, based on the principles of equity, collaboration, and the reaffirmation of national sovereignty in public-health decision-making, will make the world safer from future pandemics. The US, bolstered by its world-class medical professionals and substantial public investment in medical research, has long exerted considerable influence on global health priorities. But withdrawing from WHO places America on the outside, unable to shape the agency's policy agenda and reforms. When the next pandemic strikes, the US will be left watching from the sidelines, as WHO and its remaining member countries manage the global response and pick up the pieces as they see fit.
