The UN has expressed deep concern over escalating security incidents in the Gulf, warning that recent attacks risk undermining efforts to maintain regional stability.

Hantavirus victims on a ship in the Atlantic Ocean may have been infected prior to joining the cruise and human-to-human transmission on board cannot be ruled out 鈥� although it is rare - the World Health Organization (WHO) said on Tuesday.

96 Global Health NOW: The Growing Threat of 鈥楬idden Hunger鈥�; and Raw Milk Market Gains Ground May 4, 2026 TOP STORIES A suspected hantavirus outbreak on a cruise ship has led to three deaths, while lab results confirm six cases, ; WHO officials said the  鈥渞isk to the wider public remains low鈥� as exposure to the virus is rare and typically linked to exposure to infected rodents, .     Ghana has rejected a bilateral health agreement with the U.S., as Ghana鈥檚 leaders resisted terms requiring the sharing of sensitive health data鈥攖he same issue that led Zimbabwe to reject a similar deal and that has also prompted a court to suspend implementation of Kenya鈥檚 agreement.     School phone bans in the U.S. have had mixed results so far, , which analyzed 40,000+ schools and found that test scores and attendance have not increased; however, the study found improved student well-being over time and said long-term impacts bear further study.      The U.S. identified 50 large TB outbreaks involving 10+ related cases between 2017 and 2023, , which found that roughly two鈥憈hirds of large outbreaks occurred within family or social networks.  IN FOCUS Farmers harvest potatoes in a field in Dalingzi Village of Daxinzhuang Town in the Fengnan District, Tangshan City, China, on July 9, 2025.

Staple foods like rice, wheat, legumes, and potatoes are steadily losing vital nutrients, as rising carbon dioxide levels from climate change deplete key minerals and vitamins from crops. The shift could lead to mounting health consequences, scientists say鈥攅specially in low-income countries.     奥丑补迟鈥檚&苍产蝉辫;丑补辫辫别苍颈苍驳: Increasing carbon dioxide levels in the atmosphere alter plant development by speeding growth and boosting sugars while disrupting their ability to absorb key minerals, like zinc and iron.  

• , scientists found that nutrients have already decreased by an average 3.2% across all plants since the late 1980s鈥攁 depletion already impacting diets worldwide.  

鈥淭he diets we eat today have less nutritional density than what our grandparents ate, even if we eat exactly the same thing,鈥� said Kristie Ebi of the University of Washington鈥檚 Center for Health and the Global Environment.    The impact: Scientists warn of a future of 鈥渉idden hunger,鈥� where people eat sufficient calories but face major deficiencies. While wealthy countries can offset losses with diet changes and supplements, poorer populations reliant on impacted crops could see 鈥渄evastating鈥� impacts.  

• By mid-century, over a billion women and children could face increased risk of iron-deficiency anemia, leading to pregnancy complications, developmental problems, and death.  

• And ~2 billion people across the globe already facing nutrient shortages could see exacerbated health problems.  

Strategies needed: Researchers emphasize the need for agricultural policy geared toward growing an array of nutritious crop variants鈥攁nd the urgent need to cut carbon emissions.         ICYMI:  鈥� Johns Hopkins Bloomberg School of Public Health  DATA POINT

96 Global Health NOW: A Turning Point in TB Testing; and A 鈥楾errifying Medical Underworld鈥� Expands April 30, 2026 TOP STORIES Endometriosis diagnosis could be dramatically improved with a new imaging tool that uses a molecular tracer to help physicians observe blood vessel growth and inflammation in the body; the new tool could significantly shorten the long wait time for a diagnosis, which averages 9+ years in the U.K.  

HIV patients in Senegal are forgoing treatment amid a surge of arrests targeting the LGBTQ community after the government鈥檚 decision to increase prison term lengths and fines for same-sex sexual acts and any promotion of homosexuality.     America's infant formula supply has been deemed safe by the FDA, which tested 300+ infant formula samples for contaminants including lead, mercury, cadmium, arsenic, pesticides, PFAs, and phthalates, and found "an overwhelming majority of samples had undetectable or very low levels of contaminants.鈥�     World Cup health surveillance for the competition will be launched by global health academics at Georgetown University, who are providing a temporary surveillance hub to monitor disease risks like measles.   IN FOCUS Scanning electron micrograph of Mycobacterium tuberculosis bacteria, which cause TB. NIH//Universal Images Group via Getty Images A Turning Point in TB Testing    A new portable tuberculosis test could transform the diagnostic process for patients, making it more accessible and affordable for underserved populations, and leading to earlier treatment options, .     The traditional method: For over a century, TB diagnosis has relied on examining a patient鈥檚 phlegm samples under a microscope鈥攁n often-unwieldy, imprecise method that can miss up to half of cases or produce false positives.  

• It鈥檚 also difficult for many patients, like children and older people, to provide phlegm samples. 

Circumventing phlegm: A new molecular test detects TB bacterium DNA via a simple tongue swab or phlegm, using technology similar to that used in hospital-based COVID tests to produce results in under 30 minutes, . 

• In  researchers analyzed the tests of ~1,400 patients across Africa and Asia and found the diagnostic process met WHO accuracy standards, while proving easy to use in low-resource settings. 

• The device, MiniDock MTB, was developed by the Chinese company Pluslife, which designed it to be low-cost, battery-powered, and simple enough to use in clinics without microscopes or advanced labs. 

• Caveats: The test may miss very early infections and cannot identify drug-resistant TB without follow-up testing. 

Implications: Easier, more reliable diagnosis could reduce missed cases, expedite treatment, and slow transmission.  HEALTH SYSTEMS A 鈥楾errifying Medical Underworld鈥� Expands     A crisis is growing in American hospitals as more facilities resort to patient 鈥渂oarding鈥�: the practice of holding admitted patients for hours or days in the emergency departments or other ill-equipped temporary locations while awaiting a hospital bed.     The reasons for the growing practice are complex, including hospital financial structures and staffing issues. But meaningful reforms have yet to be enacted.     In a deeply researched, and deeply personal report, journalist and former ER physician Elisabeth Rosenthal lays out the crisis through the lens of her late husband鈥檚 own agony in this 鈥渢errifying medical underworld鈥� in his last days before dying of esophageal cancer.     The quote: 鈥淓veryone knows about this problem, and no one cares enough to do anything about it. It鈥檚 barbaric,鈥� said Adrian Haimovich, an ED doctor in Boston.       OPPORTUNITY Funding Opportunity for Disability Inclusion  
Borealis Philanthropy's Disability Inclusion Fund is seeking joint grant proposals from organizations led by and for disabled people.  
These grants support cross-movement collaborations advancing disability justice, including community organizing, advocacy, narrative change, arts, and policy work.  

• At least one partner must be disability-focused and disability-led.

96 Global Health NOW: When Policy Shapes Biology; and How Health Misinformation is Fueling Solar Farm Fears April 29, 2026 TOP STORIES Aid groups are calling for a humanitarian corridor to be opened through the Strait of Hormuz as the war in Iran has led to the blockage of vital aid supplies, including critical medications.     Viral hepatitis remains 鈥渁 major global health challenge鈥� despite notable gains, ; while hepatitis C- and B-related deaths have declined significantly, current transmission rates of ~1.8 million infections annually show that2030 elimination goals are off-course.     Disabled Americans who receive Supplemental Security Income and live with family members who qualify for the Supplemental Nutrition Assistance Program will see their monthly benefits cut or eliminated if a Trump administration rule change moves forward; the cuts would affect ~400,000 people with dementia, developmental disabilities, and other conditions.     A former NIH aide has been on obstruction of justice and conspiracy charges for allegedly using his personal email to conceal federal records about federally funded research into dangerous viruses like the one that caused COVID-19.   IN FOCUS A view of houses in KwanGode, a rural area outside Hillcrest, South Africa. November 29, 2025. Per-Anders Pettersson/Getty When Policy Shapes Biology    The introduction of powerful anti-HIV drugs in regions like South Africa鈥檚 KwaZulu-Natale province has rewritten disease outcomes of the populations there. But the intervention has also reshaped the DNA of people in the region, 鈥攕lowing evolutionary changes that were being driven by the epidemic, . 

• In KwaZulu-Natal, extreme AIDS mortality before 2005 drove measurable genetic change over a decade, rapidly reshaping immune system genes.  

• The inflow of antiretroviral drugs notably slowed this process.  

Deep, downstream effects: Abrupt funding cuts to programs like PEPFAR and those affecting programs backed by the Global Fund to Fight AIDS, Tuberculosis and Malaria risk undoing that progress, potentially allowing both the epidemic and its biological impacts to intensify again. 

• Such interruptions and reductions have eroded critical infrastructure needed to test, track, and treat the virus, impacting not only treatment but the ability to prevent it, .  

• South Africa鈥檚 uptake of lenacapavir, for example, will be heavily affected by funding cuts, , .

96 Global Health NOW: UK Cuts Imperil Polio Eradication; and How One Sudanese Surgeon Held Back the Tide April 28, 2026 TOP STORIES Ghana has rejected a U.S. proposal for a bilateral health aid deal because of a requirement that it share health data; Zimbabwe shot down a similar America First Global Health Strategy-based proposal for the same reason.  

Hundreds of hepatitis B infections and more liver cancer cases will likely follow the Trump administration鈥檚 policy that canceled a recommendation that the hepatitis B vaccine be given to infants within 24 hours of birth, .  

Strict limits on girls鈥� education and women鈥檚 work opportunities in Afghanistan may cause a shortage of 25,000 women teachers and health workers by 2030, .      48% of newborns infected with chikungunya during birth will experience severe neurological problems, including seizures, bleeding in the brain, and other issues, ; babies who appear healthy at birth can experience fever, persistent crying, and feeding problems three to seven days later.    IN FOCUS: GHN EXCLUSIVE A health worker administers polio drops to a child on a nationwide week-long poliovirus eradication campaign. Karachi, Pakistan, September, 1, 2025. Asif Hassan/AFP via Getty UK Cuts Imperil Polio Eradication 
Anne Wafula Strike once proudly served as the U.K.鈥檚 鈥減oster girl鈥� for polio eradication. Today, the Kenyan-born paralympic athlete and polio survivor has a different message: 鈥淚t feels we were running a group relay and just before the finish line, someone deliberately dropped the baton.鈥� 
  Last month, the Global Polio Eradication Initiative (GPEI) lost its largest contributor . The move is part of Prime Minister Keir Starmer's sweeping 40% reduction in foreign aid, the largest percentage cut to development assistance by any government. 
  With the world on the cusp of eradicating the disease, 鈥渋t鈥檚 the worst possible moment鈥� to abandon funding, says Shahin Huseynov, WHO鈥檚 polio coordinator for Europe. Only two wild polio cases were reported globally in the first three months of 2026, and just two countries remain endemic鈥攂ut poliovirus has been found in U.K. wastewater this year.  

• Without sustained funding, the WHO warns that 200,000 children could be paralyzed by polio each year within a decade. 

What it means on the ground: The cuts will likely mean prioritizing surveillance and vaccination campaigns in the highest-risk areas, and postponing the goal of eradicating polio by 2029, says Huseynov.  
With GPEI's budget already cut 30% from prior U.S. cuts, advocates are urging the U.K. to honor its legal obligation to spend 0.7% of national income on overseas aid. 

• Reinstating polio funding would cost just $134 million, a fraction of what's been cut. 

There鈥檚 hope that other countries will step in鈥攕uch as Australia, Spain, Canada, and Korea鈥攚ho are still 鈥渓ooking, kind of, to use their development assistance funds in a very positive way,鈥� says Adrian Lovett of the ONE Campaign.    Nevertheless, a major concern is the signal the cuts send to other countries: 鈥淚t鈥檚 not just about money. It鈥檚 about solidarity,鈥� says Huseynov.
  GLOBAL HEALTH VOICES CONFLICT How One Sudanese Surgeon Held Back the Tide    Even as missiles hit Al Nao hospital, as electricity faltered, supplies dwindled and hospital staffers fled, orthopedic surgeon Jamal Eltaeb kept working.    Al Nao is one of the only functioning hospitals in the region outside Khartoum in civil war-torn Sudan鈥攁nd Eltaeb knew it was a lifeline for hundreds of desperate patients.  

• For three years, he has found a way to keep caring for them鈥攄espite direct attacks on the hospital and amidst mass-casualty bomb strikes where 100+ wounded patients needed emergency care.  

• 鈥淲e were working everywhere, in tents, outside, on the floor, doing everything to save patients鈥� lives,鈥� said Eltaeb, who was just recognized with the $1 million Aurora Prize for Awakening Humanity.

• Three new rapid diagnostic tests are also rolling out, designed to detect mutating parasite strains that previously slipped through standard testing. 

And new threats: There is increasing evidence that parasites are growing resistant to artemisinin鈥攖he 鈥渂ackbone鈥� of lifesaving therapies鈥�. This shift, along with insecticide-resistant mosquitoes and expanding mosquito habitats, is making it difficult to build on hard-won gains like the vaccine rollouts.     Ongoing toll of disruption: Meanwhile, malaria programs throughout Africa are still seeing the effects of the sudden USAID cuts last year, . In Zambia, for example, malaria hospitalizations are now increasing鈥攍ikely due to the lack of regular USAID-funded spraying, doctors say.

On a red running track in eastern Uganda, coach Zuena Cheptoek is doing more than training runners. For many girls in the Sebei subregion, she is also a confidante, a mentor and first line of protection against female genital mutilation, child marriage and abuse.

Scientists have developed a strategy to boost the cancer-fighting power of natural killer (NK) cells, part of the immune system鈥檚 first line of defence. NK cells can detect and destroy cancer cells, but tumours often create a protective barrier that blocks them, allowing cancer to grow.

Researchers at 涩里番鈥檚 Rosalind & Morris Goodman Cancer Institute, in collaboration with the Research Institute of the 涩里番 Health Centre, found that suppressing two specific proteins helps NK cells overcome this blockage, turning them into more potent cancer killers.

Over the past 50 years, vaccines have saved more than 150 million lives, as ordinary people chose to protect themselves, their children and their communities from diseases like measles, diphtheria, pertussis, polio, and rotavirus. 

A growing share of global hunger is becoming entrenched in a small group of conflict-hit countries, with two-thirds of people facing acute food insecurity concentrated in just 10 nations, a major international report backed by UN agencies warns.

• 鈥淭he health impacts of climate change are intensifying faster than our response is keeping up,鈥� said Joacim Rockl枚v, co-director of the Lancet Countdown Europe. 

Heat-related harms: Compared with the 1990s, extreme heat alerts are up 318%, and nearly all monitored European regions saw an increase in deaths attributable to heat.  

• Heat is also exacerbating sleep disruption and complications in chronic diseases and birth outcomes. 

Accelerating disease: The overall average risk of dengue outbreaks in Europe has quadrupled over the last decade, and reported cases of West Nile virus, chikungunya, and Zika virus are also rising regionwide.  

Food insecurity: Meanwhile, drought is contributing to rising food prices, which pushed over a million more people into moderate or severe food insecurity in 2023 compared to past decades. 

Lagging political response: While Europe has been a global leader in climate policy progress, the report warns that political and public engagement are stalling, and urges further actions 鈥渘eed to be accelerated鈥� including:  

• Swifter transition away from fossil fuels to other energy sources.  

• Implementing early warning systems for heat and other climate dangers into health care.

MENTAL HEALTH Burkina Faso鈥檚 Psychiatric Care Deficit     In Burkina Faso, access to mental health care is scarce, with just 11 psychiatrists available to a population of 20 million+ people.     Strained system: Mental health services were already fragile, but recent years of conflict and insecurity in the region have led to the withdrawal of NGOs that helped provide care.  

• Meanwhile, a key nurse training program has been suspended, and the country is dealing with an exodus of medical professionals to other countries.  

Cultural dynamics: A great deal of misinformation and stigma are still attached to mental health disorders, and families often turn to spiritual healers for help instead of medical care.    Hope on the horizon? The government has announced a plan to train and employ 60 psychiatrists over the next five years.      OPPORTUNITY Take a Load Off ...

Despite significant funding cuts, the World Health Organization (WHO) was able to support significant national health gains for hundreds of millions of people in 2025, according to its annual Results Report released on Thursday.

96 Global Health NOW: The Civilian Impact of War in Iran; and A Disease-Busting House Design April 22, 2026 TOP STORIES Human rights violations are on the rise internationally at the hands of both states and non-state actors who largely face no accountability, ; despite the grim findings, the report praises the 鈥渕asterful work鈥� of diplomats and activists seeking to strengthen civil rights and liberties.     Nearly half of U.S. children breathe dangerous levels of air pollution, , which also warned that the Trump administration鈥檚 sweeping rollback of protections will worsen the outlook.      A major mRNA vaccine trial will launch soon in Britain as the country seeks to prepare for a potential bird flu pandemic; the trial, led by Moderna and the U.K. Health Security Agency, will recruit 3,000 participants to test the human vaccine鈥檚 effectiveness.      WHO-recommended antibiotics for neonatal sepsis are largely ineffective in low-resource nations, of antibiotic resistance, which found that antibiotics like ampicillin and gentamicin were active against only 25% of cases in which they were used and had 鈥渓imited coverage against locally prevalent, highly resistant pathogens.鈥�   IN FOCUS A woman looks out over Resalat Square, where photos of civilians killed in recent U.S.-Israeli strikes are displayed. Tehran, Iran, April 20, Fatemeh Bahrami/Anadolu via Getty The Civilian Impact of War in Iran   The war in Iran is taking a deepening toll on civilian life as widespread damage to the country鈥檚 already-fragile natural resources, infrastructure, and health systems is 鈥減ushing one of the world鈥檚 most environmentally vulnerable regions toward catastrophe,鈥� (CAP).     So far, 1,700+ civilians鈥攊ncluding at least 254 children鈥攈ave been killed, .  

• But the true toll is difficult to gauge due to restricted reporting, damage to hospitals, and widespread communications blackouts.  

Health systems hollowed out: Even before the war, Iran鈥檚 health care system was weakened by sanctions and violence from recent unrest. As of April 3, ~300 medical facilities had been damaged, further hampering care, per CAP.     Environmental emergency: Already strained by years of drought and climate impacts, the region now faces 鈥渃ompounding harms鈥� from strikes on oil facilities and industrial sites鈥攍eading to long-term ecological risks from air, water, and soilcontamination.     Water scarcity, 鈥渇ood catastrophe鈥�: Attacks on water infrastructure threaten access to drinking water across the region. Meanwhile, analysts say the conflict鈥檚 impact on global food prices could lead to 鈥渃atastrophe,鈥� as shipping disruptions lead to shortages in oil and fertilizer needed for agricultural production, .  

• Such impacts will be most deeply felt by low-income countries in Africa and Asia.  

Call for humanitarian intervention: The report calls for urgent aid, but also long-term remediation centered on environmental harm鈥攊ncluding surveillance for chronic disease, soil recovery, and investments in more resilient water systems.

Well-designed 鈥淪tar Homes鈥濃�攚hich promote airflow, block insects, and feature outdoor latrines and rainwater collection systems鈥攃an reduce child mortality, demonstrates a randomized controlled trial in southern Tanzania, .    Per the research, led by Lorenz von Seidlein of the Mahidol-Oxford Tropical Medicine Research Unit: 

• Children under 13 living in Star Homes were 44% less likely than those in the control group to suffer from malaria.

• Cases of diarrhea and respiratory infections were down by 30% and 18%, respectively.  

Drawbacks: The biggest barrier to broader application? The $8,800 price tag. But Seidlein says the goal wasn鈥檛 to prove that millions of Star Homes should be built. 

• The study showed that 鈥渋f you use better principles in building, you can probably achieve a massive effect,鈥� he said.

More than 840,000 people die each year from health conditions linked to risks such as long working hours, job insecurity, workplace harassment and bullying, according to a new report by the International Labour Organization (ILO). 

Extreme heat is pushing global food and farming systems to the brink, threatening the livelihoods of over a billion people as rising temperatures and more frequent heatwaves redefine how food is produced worldwide, a new UN report warns.
