Drawing on a landmark 25-year study that followed Quebec children into adulthood, 黑料网 researchers have identified two distinct patterns in how suicidal thoughts emerge and the early signs that are often missed.

Suicidal thoughts are increasingly common among youth, but how they begin and what mental health symptoms often precede them are poorly understood, the researchers said.

As typhoons lash parts of Asia and cause flooding, evacuations, and hundreds of deaths, a UN agency says that current warning systems are inadequate against today鈥檚 more frequent, more intense storms.

• Typhoon Wipha struck the Philippines on Monday and early today with torrential rains that left parts of the country with knee- to waist-deep flooding, .


• Nearly 50,000 people living near the Marikina River in the Manila region and in the Quezon and Caloocan cities have been evacuated, . At least five people are dead and seven missing.


• Vietnam is bracing for 500mm (~20 inches) of rain as well as flooding and landslides caused by Wipha, now downgraded to a tropical storm.


• More than 120 people in Punjab, Pakistan鈥檚 most populous province, have died in 鈥渆xceptional high鈥� floods since monsoon rains started June 26, .

A better warning system: World Meteorological Organization officials said yesterday that they are seeking to expand the  flood forecasting system worldwide by 2027, . The system, currently used in 70+ countries, draws on satellite data, radar, and weather modeling to provide hours of advance warning.

Scientists are gaining new insights into how H5N1 could spread among dairy cattle, particularly two potential routes: contamination from house flies, and from cows and calves nursing.

Background: When H5N1 first emerged in dairy cattle, researchers believed contaminated equipment and movement of infected cattle were key factors in virus spread. 

• But when outbreaks continued after addressing those issues, scientists expanded their investigation and found new insights:

Flies: Avian influenza detected in house flies leads scientists to believe that the insects can 鈥渕echanically鈥� acquire and move the virus.

GLOBAL HEALTH VOICES NEGLECTED DISEASES Two Countries Validated as Trachoma-Free
Trachoma has officially been eliminated in Burundi and Senegal, making them the eighth and ninth countries in the African region to reach that public health milestone.

• The disease鈥�the first eliminated neglected tropical disease in Burundi鈥攃an lead to scarring, in-turned eyelids, and blindness, and primarily affects regions where clean water and sanitation are scarce, .


• In Senegal, trachoma is the second neglected tropical disease to be eliminated after being declared free of dracunculiasis (Guinea-worm disease) transmission in 2004, .


• 90% of the global trachoma burden is in Africa. 


• 93 million people live in at-risk areas as of April 2024. 

Success in action: Both countries implemented WHO-recommended SAFE strategy elimination interventions for trachoma, which include surgery to treat the late-blinding stage of the disease, antibiotic mass drug administration of azithromycin, public awareness campaigns, and improved water supply and sanitation access.

St. Thomas, Ontario, July 9. Geoff Robins/AFP via Getty As Measles Spreads, Strategies Shift 
As countries continue to reckon with the worst measles outbreaks in years, many health practitioners say they are shifting mitigation tactics in real time鈥攎oving from a vaccine-centric approach to improved overall messaging and health care access. 

In Canada: 3,800 cases have been reported, nearly 3X the number of U.S. cases, . 

• Vaccine uptake has dropped significantly since the pandemic, researchers say. Vaccine opposition is a key contributor to that, but so are pandemic-related disruptions. 


• As clinics respond to an outbreak among Ontario鈥檚 Mennonite community, health workers are seeking to address language barriers, build trust, and 鈥渃hange how Low German鈥搒peaking families and the medical system interact with each other,鈥� writes a . 

In England: 500+ cases have been reported this year, with 68% among children under 10, . 

• While vaccine hesitancy has driven lower MMR vaccine uptake, poverty-driven inequality is also contributing to missed appointments, say researchers calling for improved access, . 

In the U.S.: Infections have surpassed 1,300, with Texas alone logging 760+, . 

• Health workers in the state say that going forward, they may pivot from a vaccine-focused approach and emphasize better testing and offering additional treatments to build trust, .

Treating meth addiction remains a critical challenge for many U.S. communities, as no effective medication is available to help manage dependence. 

• With few options, an innovative strategy is gaining traction: contingency management (CM), which rewards patients for abstaining from meth.

How it works: Patients who test negative for meth at a clinic receive vouchers or cash rewards that increase with continued abstinence鈥攖ypically totaling ~$600 over three to six months. 

Outcomes: Research has shown that CM outperforms counseling or therapy for stimulant addiction; about half of patients who complete CM remain drug-free after one year.

Growth鈥攂ut for how long? CM programs have expanded to 600+ sites nationwide, aided by federal support and private insurers. 

• But the Trump administration鈥檚 health overhauls may impact such programs鈥� future. 

GLOBAL HEALTH VOICES HEAT Coverage When Temperatures Climb
A heat insurance program in India is offering new financial relief for daily wage workers who lose income or are forced to stop working during extreme heat.

• The coverage is 鈥減arametric,鈥� which means payouts are triggered by a measurable event, like temperature exceeding a set threshold, and no claims are required. 

Background: Such plans are seen as critical as more regions face record heat waves. One in the city of Ahmedabad that now covers ~50,000 members was set up through collaboration of the Indian trade union Employed Women鈥檚 Association and the nonprofit Climate Resilience for All. 

Impact: The payouts not only help people avoid exploitative loans to pay bills; they also give workers a chance to rest or fund alternative business opportunities until they can resume work.
