Viral outbreaks are always on the horizon – here are the viruses an infectious disease expert is watching in 2026

A new year might mean new viral threats.

Old viruses are constantly evolving. A warming and increasingly populated planet puts humans in contact with more and different viruses. And increased mobility means that viruses can rapidly travel across the globe along with their human hosts.

As an infectious diseases physician and researcher, I’ll be keeping an eye on a few viruses in 2026 that could be poised to cause infections in unexpected places or in unexpected numbers.

Influenza A – on the cusp of a pandemic

Influenza A is a perennial threat. The virus infects a wide range of animals and has the ability to mutate rapidly. The most recent influenza pandemic – caused by the H1N1 subtype of influenza in 2009 – killed over 280,000 people worldwide in its first year, and the virus continues to circulate today. This virus was often called swine flu because it originated in pigs in Mexico before circulating around the world.

Most recently, scientists have been monitoring the highly-pathogenic avian influenza H5N1 subtype, or bird flu. This virus was first found in humans in southern China in 1997; wild birds helped spread the virus around the world. In 2024, the virus was found for the first time in dairy cattle in the U.S. and subsequently became established in herds in several states.

The crossover of the virus from birds to mammals created major concern that it could become adapted to humans. Studies suggest there have already been many cow-to-human transmissions.

In 2026, scientists will continue to look for any evidence that H5N1 has changed enough to be transmitted from human to human – a necessary step for the start of a new influenza pandemic. The influenza vaccines currently on the market probably don’t offer protection from H5N1, but scientists are working to create vaccines that would be effective against the virus.

Mpox – worldwide and liable to worsen

Mpox virus, formerly called monkeypox virus, was first discovered in the 1950s. For many decades, it was seen rarely, primarily in sub-Saharan Africa. Contrary to its original name, the virus mostly infects rodents and occasionally crossed over into humans.

Mpox is closely related to smallpox, and infection results in a fever and painful rash that can last for weeks. There are several varieties of mpox, including a generally more severe clade I and a milder clade II. A vaccine for mpox is available, but there are no effective treatments.

In 2022, a global outbreak of clade II mpox spread to more than 100 countries that had never seen the virus before. This outbreak was driven by human-to-human transmission of the virus through close contact, often via sex.

While the number of mpox cases has significantly declined since the 2022 outbreak, clade II mpox has become established around the world. Several countries in central Africa have also reported an increase in clade I mpox cases since 2024. Since August 2025, four clade I mpox cases have occurred in the U.S., including in people who did not travel to Africa.

It is unclear how mpox outbreaks in the U.S. and abroad will continue to evolve in 2026.

Oropouche virus – insect-borne and poised to spread

Oropouche virus was first identified in the 1950s on the island of Trinidad off the coast of South America. The virus is carried by mosquitoes and small biting midges, also known as no-see-ums.

Most people with the virus experience fever, headache and muscle aches. The illness usually lasts just a few days, but some patients have weakness that can persist for weeks. The illness can also recur after someone has initially recovered.

There are many unanswered questions about the Oropouche virus and the disease it causes, and there are no specific treatments or vaccines. For decades, infections in people were thought to occur only in the Amazon region. However, beginning in the early 2000s, cases began to show up in a larger area of South America, Central America and the Caribbean. Cases in the United States are usually among travelers returning from abroad.

In 2026, Oropouche outbreaks will likely continue to affect travelers in the Americas. The biting midge that carries Oropouche virus is found throughout North and South America, including the southeastern United States. The range of the virus could continue to expand.

Even more viral threats

A number of other viruses pose a risk in 2026.

Continuing global outbreaks of chikungunya virus may affect travelers, some of whom may want to consider getting vaccinated for this disease.

Measles cases continue to rise in the U.S. and globally against the backdrop of decreasing vaccination rates.

HIV is poised for a resurgence, despite the availability of effective treatments, due to disruptions in international aid.

And as-yet-undiscovered viruses can always emerge in the future as humans disrupt ecosystems and travel around the world.

Around the world, people, animals and the wider environment are dependent on each other. Vigilance for known and emerging viral threats and the development of new vaccines and treatments can help keep everyone safe.The Conversation

3 things to know about Kevin Warsh, Trump’s nod for Fed chair

3 things to know about Kevin Warsh, Trump’s nod for Fed chair

After months of speculation, President Donald Trump nominated Kevin Warsh on Jan. 30, 2026, to be the next chair of the Federal Reserve.

If confirmed by Congress, Warsh will inherit leadership of the U.S. central bank at a delicate time. For months, current Fed Chair Jerome Powell has come under attack from the Trump administration for failing to heed the president’s call for lower interest rates. The fight has put into question the central bank’s independence and its role in stewarding the economy.

Powell’s term as chair will end in mid-May, leaving his successor to navigate an economy that has improved on some fronts but remains uneven and uncertain.

But what should America expect from the next Fed chair? Here are three things to note about Trump’s nominee.

1. He is a familiar face …

Warsh brings deep experience with monetary policymaking to the role.

A graduate of Stanford University and Harvard Law School, he served as special assistant to the president for economic policy and executive secretary of the White House National Economic Council under President George W. Bush before becoming one of the youngest members of the Federal Reserve Board of Governors.

Warsh is no newcomer to discussions about Federal Reserve leadership. He was a finalist for the job in 2017, when Trump instead appointed Powell. Trump has since stated that he made a mistake by not selecting Warsh then – though clashes between Trump and Powell may have influenced that view.

Warsh’s credentials are unquestionable. As a governor of the Federal Reserve Board from 2006 to 2011, he worked closely with other policymakers and with Wall Street during the global financial crisis of 2008. Since departing the Fed, he has returned to Stanford as a visiting fellow at the Hoover Institution and a lecturer at the Graduate School of Business, as well as a member of the Panel of Economic Advisers of the Congressional Budget Office.

He also has ties to the finance industry. He began his career in mergers and acquisitions at Morgan Stanley and, since leaving the Fed, has worked as a partner at Duquesne Family Office, an investment firm that manages the personal wealth of hedge fund manager Stanley Druckenmiller and other investors.

In 2016, Trump included Warsh in an economic advisory group assembled during his transition. Critics of Warsh’s nomination point toward his father-in-law, Ronald Lauder, a college friend and donor of the president, as evidence of politicization.

2. … with evolving monetary views

The big question people have is what a Warsh Fed would mean for monetary policy – that is, is it likely to play tight or loose with rates.

When the economy is growing quickly, like in 2021, the Federal Reserve tightens policy by raising interest rates to avoid the kind of economic growth that may not be sustainable long term and can lead to bubbles. However, during downturns, like in 2008 or 2020, the economic policy that can provide a backstop for the economy is looser. The Fed tends to lower rates in these situations, which supports growth.

Warsh’s views on monetary policy have long been considered hawkish, meaning he is inclined toward tighter policy and generally higher interest rates to keep inflation in check, even at the expense of slower economic growth. During his previous tenure at the Fed, he signaled concern about expansive monetary tools such as quantitative easing, in which the central bank buys Treasurys and other securities to stimulate the economy. This resulted in what Warsh called a “bloated” Fed balance sheet that held almost US$9 trillion of debt at its peak in 2022.

In recent public remarks leading up to his nomination, however, he has increasingly aligned in part with Trump’s push for lower interest rates and discussed establishing a new Treasury-Fed Accord, like in 1951, when Fed independence from fiscal authorities such as the Treasury Department was established.

3. His nod highlights fight over Fed independence

A central question surrounding this nomination is whether it promotes the politicization of the Federal Reserve.

The Fed’s independence from day-to-day political pressure has long been viewed as a cornerstone of U.S. economic policymaking. Decisions about interest rates, inflation control and financial stability are insulated from electoral politics for that reason. A truly independent Fed can resist making decisions that provide a short-term economic bump – something incumbent governments tend to like – but may lead to longer-term economic pain down the road.

The Fed tends to use its monetary policy tools carefully. Yet politicians tend to want looser monetary policy so the economy grows fast and they get credit for it.

And Warsh’s nomination can be seen in the context of a broader push from the executive branch to exert greater influence over monetary policy. Given Trump’s public criticism of Powell and vocal calls for his early departure, the president almost certainly intended to nominate someone who would lower interest rates according to preferences stated by the administration.

Critics of the nomination have argued that Warsh has a tendency to be more opportunistic with his policy views than Powell and other economists, who try to ignore political preferences.

As such, Warsh’s nomination encapsulates more than just a leadership transition. It highlights the ongoing tensions between political priorities and the traditional economic playbook, between short-term growth pressures and long-term stability, and between institutional independence and democratic accountability.

Time will tell whether he turns out to be hawkish or politically motivated as chair, if he is confirmed.The Conversation

How Iran is powering Russia’s next generation drone war

Russia’s drone pipeline: How Iran helps Moscow produce an ever-evolving unmanned fleet

With Russian ground troops bogged down in a grinding war of attrition, Moscow is striving to press home its advantage in the skies – through an ever-evolving army of drones, courtesy of Iran.

In early January, wreckage of a drone found in Ukraine hinted at a new high-speed model of drone being deployed by Russia in the conflict. It prompted Ukraine President Volodymyr Zelenskyy to air fears over failing to keep pace. “We produce (drones) at about 1,000 a day. We really produce them, but it’s not enough. It’s still not enough,” he told an audience of political business leaders at the World Economic Forum on Jan. 22, 2026.

Ukrainian intelligence suggests that Moscow, too, will also soon be pumping out 1,000 drone units a day, in large part thanks to the support and technical assistance of Iran. A central concern for Ukraine is Russia’s increasing production of long-range attack drones that it has used in mass attacks to strike targets in Ukraine.

Tehran’s role in supplying Russia with hundreds of long-range, kamikaze-style drones is long known. But what has gone largely unnoticed outside Ukraine is Iran’s central role in teaching Russia to produce these drones itself.

As an expert on weapons technology and former assistant director of the CIA for weapons and counterproliferation, I believe use of Iranian technology has helped Russia develop a fleet of sophisticated drones able to erode Ukrainian air defenses and strain the country’s resolve. By doing so, Moscow is able to preserve more expensive missiles for long-range precision strikes.

Designed in Iran, produced in Russia

Both Ukraine and Russia have ramped up drone production since the beginning of the current conflict in February 2022.

Russia was initially unable to produce large numbers of kamikaze drones, and the country’s military seemingly did not at first understand the decisive role long-range strike drones could play. Instead, Moscow invested in traditional battlefield weapons, such as missiles. It mainly thought of drones as carrying out the roles of intelligence, reconnaissance and surveillance.

Tehran had the expertise Russia needed. It also had an existing defense relationship with Russia. Moreover, faced with a cash-strapped economy due to yearslong sanctions, Iran needed money.

Since probably about early 2022, Tehran has been providing drones and drone technology to Russia for use in Ukraine. Later that year, Russia and Iran signed the agreement to set up a production plant in Russia for Iranian-designed attack drones.

With Iranian blueprints and technology, a production plant in Tatarstan in western Russia now produces large numbers of drones originally designed by Iran. At this factory, Russia manufactures the Geran-2, Moscow’s name for the Iranian Shahed-136 strike drone.

Easily identifiable by its delta-wing shape, the drone has optimized certain design features, such as range, endurance and weight capacity. It can carry an estimated 90 to 110 pounds of explosives hundreds of miles.

Meanwhile, the delta-wing design optimizes precision diving, helps prevent stalling at low speeds, and increases the drone’s stability during the attack phase.

These features enable targeting of strategic infrastructure at much less cost than long-range missiles.

Russia can now produce hundreds of one-way Geran-2 attack drones a day. It may soon be able to launch thousands in salvos.

Russia is also modifying and enhancing the drones with features such as precise navigation, heavier warheads and new engines.

Some reports claim Russia is testing telemetry and video links to fly drones remotely, a significant improvement over its current preprogrammed design that would improve accuracy and range. Iran also supplied Russia with technology to build a jet-powered drone variant based on the Shahed-238 that can fly faster.

Called the Geran-3, Russia has produced and used fewer of these drones, whose jet power makes them more challenging for Ukrainian air defense to detect and intercept. New generations of the drone – Geran-4s and Geran-5s – have since been rolled out and apparently deployed in the war with Ukraine.

Sanctions-busting procurement

Even with the blueprints and Iranian assistance, Russia is still reliant on Western and Chinese suppliers for some drone components, many of them commercial, off-the-shelf technology. These include the engine, fuel pump, GPS and navigation systems, semiconductors and components for antennas.

To assist Russia, Iran exploits its networks of brokers and companies in acquiring Western components to evade international sanctions.

A procurement network headed by the Iranian company Sahara Thunder used shipping firms in the UAE and India to sell Russia the original Iranian drones and components and to negotiate the deal for the production plant.

The U.S. Treasury Department has sanctioned this firm and others involved in the drone sales, but Iran set up new companies to help Moscow acquire components. Multiple studies and reports documenting the inclusion of foreign components in downed Geran-2s show Moscow’s continued acquisition of these parts, almost certainly with Iranian assistance.

A weapon of terror

Russia uses the Geran and other longer-range Iranian and Russian models to purposefully target civilians and civilian infrastructure in Ukraine, including residential housing in Ukrainian cities. Russia has even targeted first responders and humanitarian distribution points, according to a United Nations account.

In fact, the U.N. concluded in October 2025 that Russia’s use of short-range, unmanned aerial vehicles against civilians in southern Ukraine constituted a crime against humanity and a war crime.

A two-day attack in May 2025 on the Ukrainian cities of Kharkiv in the northeast and Odessa in the south highlights the destructive power and human cost of the drone attacks. According to accounts in the Kyiv Post, Russia launched over 100 drones. In Kharkiv, three blocks were burned down, including 90 shops, and two people were injured. In Odessa, the drones killed one person and damaged residential buildings.

Beyond psychologically tormenting the Ukrainian population, these drones have a profound effect on the battlefield.

Ukraine has responded to Russia’s battlefield success with the Iranian-designed drones by diversifying the types of drones it manufactures, attacking Russian infrastructure for manufacturing drones and developing counter-drone technologies.

A mutually beneficial arrangement

Iran also benefits from this terror campaign. Reeling from the economic impact of sanctions, Iran will make an estimated US$1 billion to $1.75 billion from the deal for drones and the production facility. Russia is reportedly paying Iran a portion of the bill in gold.

Iran is unlikely to stop its assistance anytime soon, given its own economic problems. Helping Moscow obtain drone components and even modify new versions of the Geran-2 will also benefit Iran militarily as it, too, learns to make the new drones and use them itself.

But the main beneficiary of this relationship is Moscow. Without Iranian support, Russia would face more difficult trade-offs on the battlefield. The lower-cost drones allow Russia to preserve its expensive advanced missiles for the most significant targets in Ukraine and to employ large swarms of drones to target Ukrainian infrastructure.

And with the ground offensive yielding little progress of late for Moscow, that could be crucial as the war enters its fifth year.The Conversation
