Measles Cases and Outbreaks | Measles (Rubeola) | CDC
There have been 32 new outbreaks** reported in 2026, and 93% of confirmed cases (2,082 of 2,231) are outbreak-associated (717 from outbreaks starting in 2026 and 1,365 from outbreaks that started in 2025).
Influenza Vaccine Effectiveness Against Pediatric Death in the United States: 2016–2025 | Pediatrics | American Academy of Pediatrics
Pediatrics 2026; e2026076453. 10.1542/peds.2026-076453 ... Seasonal influenza vaccination has been shown to reduce the risk of influenza and severe complications among children aged 6 months and older.
Social Needs Intervention in Primary Care Not Associated With Increased Use of Services
Participating sites excluded federally qualified health centers (FQHCs) and practices that already had routine screening protocols in place. The parents (N = 1882) of children aged 2 months to 10 years were enrolled either during usual care or WE CARE phases at their well-child v...
Research of the Day
Family-Based Treatment for Childhood Obesity: 5-Year Outcomes
This long-term follow-up evaluated family-based behavioral treatment (FBT) for childhood obesity. Children who received FBT maintained healthier BMI trajectories compared to usual care, with parental involvement being key to sustained success.
Key findings: (1) 25% greater BMI reduction maintained at 5 years; (2) Parental BMI change correlated with child outcomes; (3) Maintenance sessions improved long-term success.
Engage the whole family in obesity treatment—target the child alone is less effective. Focus on sustainable lifestyle changes, address family habits, and plan for ongoing support.
Popular Beliefs
Wait 30 minutes after eating before swimming
What the evidence shows: There's no evidence that swimming after eating causes cramps or drowning. While digestion diverts some blood flow to the gut, it doesn't impair swimming ability in normal circumstances. Common-sense supervision is always important regardless of meal timing.
Children outgrow ADHD
What the evidence shows: While symptoms often change with age, approximately 60% of children with ADHD continue to have symptoms into adulthood. Hyperactivity typically decreases, but inattention and impulsivity often persist. Ongoing monitoring and treatment adjustment is important across the lifespan.
ADD/ADHD is caused by poor parenting or too much sugar
What the evidence shows: ADHD has strong genetic and neurobiological components. While environment can influence symptom severity, poor parenting and diet do not cause ADHD. Evidence-based treatments include behavioral therapy and, when appropriate, medication. Blaming parents is harmful and delays effective intervention.
Behaviors
Growth Mindset and Academic Resilience in Middle School
This school-based intervention taught growth mindset principles to 4,000 middle schoolers. Students who internalized growth mindset showed improved grades, greater persistence, and reduced anxiety around academic challenges.
Key findings: (1) 0.3 GPA improvement in intervention group; (2) 25% reduction in test anxiety; (3) Effects largest for initially low-performing students. Teacher reinforcement of messages enhanced effects.
Praise effort over ability when discussing academics with patients. Encourage families to use growth mindset language. Struggle is part of learning, not a sign of inability.
Genetics
Genetic Predictors of Peanut Allergy Persistence
Genome-wide association study identifies genetic variants associated with peanut allergy persistence versus resolution. Children with certain variants are more likely to outgrow their allergy, informing timing of oral food challenges.
Key findings: (1) 4 genetic variants strongly associated with persistence; (2) Genetic testing could reduce unnecessary avoidance and challenges; (3) Environmental factors remain important in allergy development.
Genetic testing may soon help predict which children will outgrow allergies. For now, continue regular reassessment with IgE testing and oral challenges as clinically indicated.
