Robert F.

96 Global Health NOW: Reproductive Care Collapses in Afghanistan Plus: Time to Chart a New Path to Africa鈥檚 Malaria-Free Future January 29, 2026 TOP STORIES Malaria deaths could spike to half a million across Africa over the next 25 years due to climate change, 鈥攚hich finds that shifting and extreme weather patterns could lead to an additional 123 million malaria cases across the continent.     Two animal-borne pathogens pose a growing threat to humans, warns a new ; the viruses, influenza D virus and canine coronavirus, have been 鈥渇lying under the radar,鈥� but conditions are shifting that have improved their capacity to spread among humans, researchers say.     HPV screening rates among underserved groups in Australia were 鈥渟ubstantially boosted鈥� through cervical sample self-collection programs, ; participation was especially high among women who were 10+ years overdue for screening and those living in very remote areas.     Twice-yearly PrEP is slowly becoming more accessible to people in the U.S., as insurers gradually agree to cover the high-cost drug, Yeztugo鈥攁n injection of the drug lenacapavir.  IN FOCUS Farida, 30, a midwife, monitors pregnant women close to delivering, at the provincial hospital's maternity department, on August 27, 2025, in Ghazni, Afghanistan. Elise Blanchard/Getty Images Reproductive Care Collapses in Afghanistan 
Women in Afghanistan increasingly have nowhere to turn to prevent pregnancies or find basic prenatal services, as the country鈥檚 reproductive care system deteriorates under the Taliban.     Birth control banned: The  started in 2023, with contraceptives swiftly disappearing from shelves and doctors forbidden from dispensing them鈥攅ven for women whose lives could be threatened by pregnancy.     Clinic closed: Clinics accused of violating the Taliban鈥檚 orders face risk of closure; doctors have also been forced to close their doors after the sudden drop in international aid last year. 

• 440+ hospitals and clinics have closed or reduced services in Afghanistan in the last year, . 

• Since then, women have been left largely to fend for themselves, with minimal to no prenatal care amid risky pregnancies, complications, and miscarriages.  

Dangers at home: Meanwhile, medical workers say most of the pregnant women they see are malnourished, and many women miscarry because of domestic violence and overwork.     The quote: 鈥淭hey broke her with fear, pregnancies and violence,鈥� said the mother of one 36-year-old woman who has slipped into a "permanent state of confusion鈥� after nine pregnancies and six miscarriages.     GHN EXCLUSIVE COMMENTARY Faith, 3, vaccinated in the world's first malaria vaccine (RTS, S) pilot program, plays at home in Mukuli, Kenya, on March 7, 2023.

As wealthy countries cut assistance and malaria surges in parts of Africa, the continent鈥檚 leaders must chart a new path to a malaria-free future, write Corine Karema, Francine Ntoumi, and Garry Aslanyan . 

• The recent dramatic reduction in aid is disrupting core activities like disease surveillance, supply chains for medicines, and delivery of care.   

A leadership moment: Africa needs to invest more of its own resources. Ghana, Kenya, Nigeria, Rwanda, and Uganda are taking steps to increase their health budgets. It鈥檚 time to accelerate those gains, the authors argue.      奥丑补迟鈥檚&苍产蝉辫;苍别别诲别诲:&苍产蝉辫;&苍产蝉辫;

• All governments where malaria is endemic should have national elimination plans. 

• African institutions should set priorities, align partners around national plans, and demand accountability for results.  

• The African Union and other organizations can help coordinate efforts at the regional level, keeping malaria high on the political agenda. 

• Malaria programs need to engage other programs鈥攍ike routine immunization, antenatal care, and community outreach鈥攖o get the newly approved malaria vaccines RTS,S and R21/ Matrix鈥揗 to people.   

The takeaway: Eliminating malaria can become, they write, a defining story of African leadership that safeguards lives for generations.

An infant formula recall affecting 18 countries has been issued by French dairy company Lactalis after some batches were flagged for a dangerous toxin; the recall marks the third major infant formula recall this year following other contamination incidents from Nestl茅 and Danone.

The U.S. formally leaves the WHO today, completing a yearlong withdrawal process begun on President Trump鈥檚 first day in office in 2025, and leaving a budgetary crisis and ruptured global health security in its wake, .   
 
Global fallout: The loss of the U.S.鈥攐nce the WHO鈥檚 largest donor鈥攈as led the agency to make deep budget cuts and plan layoffs for nearly a quarter of its staff. 

• These losses, combined with the loss of U.S. cooperation, leaves the world less equipped to handle worldwide disease detection, response coordination, and intelligence sharing鈥攃rucial collaborations during recent global health crises like COVID-19 and the Ebola outbreak. 

Unpaid bills: As the U.S. departs, it is stiffing the organization ~$278 million in owed dues from both 2025 and from 2024鈥攂efore Trump took office, . The lapsed payments defy a 1948 U.S. law that likely will not be enforced. 
 
A path to return?: While global health leaders say they do not anticipate a U.S. return to the organization in the near future,  that some WHO reforms, including results-based accountability, could eventually lure the U.S. back.

Pangolins are one of the most trafficked animals in the world, as demand for their scales and meat remains high in places like Laos鈥攁 major hub of illegal wildlife trade.     Rampant trafficking threatens the mammal with extinction and poses a global health security threat, say epidemiologists.  

• Pangolins' unique immune tolerance allows them to host pathogens undetected, and the animals鈥� long captivity with other species and humans in unsanitary spaces creates a risk for spillover.  

The Quote: 鈥淭o me, this really is ground zero for disease emergence,鈥� said University of Sydney virologist Edward Holmes, who described the trade as 鈥渂oth horrendous for the animals in question, and could easily spark another pandemic.鈥�&苍产蝉辫;   ALMOST FRIDAY DIVERSION Should We All Just L眉ften Up? 
Flinging the windows open for some fresh air: It鈥檚 an invigorating feeling now and again.  

In Germany, it鈥檚 much more than that. The practice of multiple daily airings鈥攏o matter the weather鈥攊s ingrained from childhood and for tenants, often a contractual obligation.  

尝眉蹿迟别苍-濒颈迟别: But now, much to some Germans鈥� chagrin, American influencers have co-opted l眉ften under a new name: 鈥渉ouse burping,鈥� presenting it . A refreshing home hack, with no threat of eviction for noncompliance鈥攐r warning that over-commitment may ruin your relationship. 

Breeze-crossed lovers: For one German-American couple, the partner doing the heavy l眉ften-ing invited in cold air, chilly feelings, and one time, three bats, . His practice, which exceeded the l眉ften minimums required by his lease, left his American girlfriend cold and 鈥渃onfused,鈥� and their love went out the open window like stale air caught in a crossbreeze. 鈥淟眉ften is largely responsible for the fact that they鈥檙e no longer together.鈥�&苍产蝉辫;

96 Global Health NOW: Mpox鈥檚 Silent Spread; and U.K. Seeks a Road Safety Overhaul January 21, 2026 TOP STORIES U.S. lawmakers are pushing back against NIH cuts proposed by the Trump administration with a new Congressional bill that rejects a proposed 40% cut to the NIH budget and instead includes a $415 million increase and language that limits White House influence over grant funding.   
 
The Africa CDC confirmed the cancelation yesterday of a U.S.-funded study on hepatitis B vaccines involving newborns in Guinea-Bissau, citing ethical concerns over the proposed research design鈥攑articularly the possibility of delaying access to a lifesaving vaccine for some newborn participants.  
 
Prenatal exposure to wildfire smoke may be associated with an increased likelihood of autism diagnosis by age 5, ; the strongest association was found among those exposed to more than 10 days of wildfire smoke in the third trimester.  
 
A coalition of U.S. health groups has expanded a lawsuit against HHS Sec. Robert F. Kennedy Jr., challenging his agency鈥檚 鈥渆gregious, reckless, and dangerous鈥� changes to the childhood vaccine schedule; the plaintiffs鈥攚hich include the American Academy of Pediatrics, the American College of Physicians, and the American Public Health Association鈥攈ad already sued over the agency鈥檚 changes to COVID-19 vaccine policy.   IN FOCUS Social mobilizers wait for community members ahead of the launch of an mpox vaccination campaign at the General Hospital in Goma, DRC.

Mpox may be spreading asymptomatically in parts of Africa, new research shows鈥攁 revelation that could have significant implications for understanding and preventing transmission, .  
 
Researchers analyzed new and historic blood samples from 176 Nigerian adults with no known mpox exposure and discovered something unexpected: ~3% had developed new mpox antibodies over nine months鈥攊ndicating recent infection, , which was conducted by scientists at the University of Cambridge and the Institute of Human Virology Nigeria.  

• The research points not to 鈥渆xplosive spread鈥濃�攂ut rather to persistent transmission via 鈥渟poradic chains of infection鈥� shaped and potentially contained by past smallpox vaccination, .  

• The study also found no major differences in immune responses between health care workers and the general population鈥攎eaning exposure isn鈥檛 limited to medical settings, .  

Potential public health impact: The insights could reshape surveillance and prevention, especially in mpox-endemic regions where blood tests could better reveal exposure and help target vaccination efforts rather than relying on symptoms alone. 

• 鈥淚f we only look for obvious disease, we will miss part of the picture,鈥� said Alash'le Abimiku, executive director of the Institute of Human Virology Nigeria.

GLOBAL HEALTH VOICES ROAD SAFETY U.K. Seeks a Road Safety Overhaul
U.K. officials have unveiled the country鈥檚 first comprehensive road safety strategy in over a decade, aiming to cut road deaths and serious injuries by 65% by 2035. 
 
Background: Advocates and officials say the reforms come after years of inaction, as the country falls further behind European road standards. 

• 鈥淔or too long, progress on road safety has stalled. This strategy marks a turning point,鈥� said U.K. transport secretary Heidi Alexander.  

Plans include:  

• Stricter alcohol limits and higher penalties for violators. 

• Mandatory eye tests for drivers ages 70+. 

• Longer learning periods for new drivers. 

• Automatic emergency braking in all new cars. 

• Increased penalties for uninsured motorists and those not wearing seatbelts. 

• Improved crash testing.
