Geoff Robins/AFP via Getty U.S., Canada Risk Measles-Free Status
The consequences of teetering government commitments to vaccines and falling vaccination rates are emerging across North America.    Measles-free no more: Canada and the U.S. are poised to lose their status as countries that have eliminated measles, . Canada鈥檚 year of continuous measles transmission and its 5,000+ cases this year make it likely that a November PAHO meeting will determine the country is no longer measles free. The U.S. may soon get the same label.      Muzzled experts: Doctors and public health experts in Florida have been reluctant to speak out about a state plan to end required childhood vaccinations, . 

• Pediatricians are afraid of losing business, county health department officials refer reporters to state officials, and University of Florida infectious disease experts were told not to speak to reporters without supervisor approval.  

Needed: 鈥淚t鈥檚 really those vaccine champions from communities that help improve vaccination, spread awareness about the need for vaccination, and kind of create the positive change that we need in order to ensure that these outbreaks don鈥檛 persist and don鈥檛 continue to happen,鈥� 麻豆传媒网站 epidemiologist Nicole Basta .     Not needed: When a reporter asked Florida Surgeon General Joseph Ladapo if his team had created computer models of potential outbreaks after the policy change, he replied 鈥渁bsolutely not,鈥� and added that parents鈥� freedom of choice wasn鈥檛 a scientific matter.     Related:

96 Global Health NOW: Diphtheria鈥檚 Dangerous Return; Bird Flu Rebounds; and Model of Healthy Architecture October 27, 2025 Pediatrician Mohamud Omar examines a child鈥檚 tonsils in the diphtheria ward of Demartino Public Hospital in Mogadishu, Somalia, last month. Brian Otieno/The New York Times Diphtheria鈥檚 Dangerous Return    Diphtheria, a deadly bacterial disease long controlled by vaccines, is spreading again in regions destabilized by conflict and climate-driven displacement, as hospital wards throughout parts of Africa and the Middle East fill with children struggling to breathe.    Fueling factors: Mass displacement, COVID-19 pandemic disruptions, and vaccine hesitancy have left millions of children vulnerable鈥攅specially in regions with hollowed-out health systems.  

• And global aid cuts this year have contributed to severe malnutrition and the shuttering of immunization programs.  

Global spread: Outbreaks have erupted in Chad, Nigeria, Somalia, Sudan, and Yemen; sporadic cases are appearing in Europe among refugee and migrant communities.  

• While the U.S. rarely sees travel-related cases, full kindergarten vaccination rates including diphtheria coverage from 95% in 2020 to 92% in 2024鈥�25. 

High danger, urgent intervention: Diphtheria now kills up to 1 in 4 infected children in low-resource settings, prompting Gavi, the Vaccine Alliance to create emergency vaccine funding for boosters. 

• 鈥淲e didn鈥檛 even have a diphtheria support modality, because we didn鈥檛 need one. And now we have to build out a whole new process to help countries respond,鈥� said Katy Clark, a diphtheria expert with Gavi.

Beirut, Lebanon, August 14. Joseph EID/AFP via Getty Cancer Besieges Lebanon    Beirut is often shrouded in smog pumped out by unregulated vehicles and diesel generators. Cigarette smoke permeates public places.  
  The toxic air and smoke have contributed to a staggering cancer crisis in Lebanon, , which analyzes the cancer burden worldwide from 1990 to 2023 and forecasts the cancer burden up to 2050. 
  The survey projects that cancer cases and deaths will rise worldwide, especially in low- and middle-income countries. But Lebanon鈥檚 crisis is particularly acute, :  

• The country has the fastest increase in cancer incidence and deaths worldwide, with new cancer cases up 162% and deaths by 80% over the period covered in the survey.  

Systemic inaction: Lebanon has no anti-smoking or health education campaigns. And few people seek out available screening tools due to low awareness.  

• 鈥淐ancer is killing 鈥� Why have you been waiting so long to take action?鈥� study coauthor Ali Mokdad asked of the Lebanese government. 

Meanwhile, a rise of several cancers in adults of all ages worldwide could be driven by obesity, finds a separate global cancer study published in the , which recorded an uptick in cancer incidence rates from 2003 to 2017, .     Related: Of Corn and Cancer: Iowa鈥檚 Deadly Water Crisis 鈥�  Thanks for the tip, Cecilia Meisner!
