A California duck farm has tested positive for H5N9, marking the first confirmed case in the U.S. The outbreak began on November 23, 2024, after a rise in duck deaths.

H5N9 is a low-pathogenic virus that usually causes mild symptoms in birds. Officials have not reported any human infections linked to the outbreak. The virus has been detected in farmers in other countries, but no cases have been confirmed in the U.S.

A tuberculosis (TB) outbreak has become the largest ever recorded in U.S. history. Since early 2024, officials have reported 67 active TB cases and 79 latent cases.

The World Health Organization recorded 8.2 million global TB cases in 2023. This is the highest number since WHO began tracking TB in 1995. Last year, tuberculosis once again became the world’s deadliest disease.

A new study in the Journal of Infection links salmonella outbreaks to climate change. Warmer temperatures, higher humidity, and lower rainfall increase infection risks.

Researchers examined 14 weather factors to estimate salmonella rates. They used case reports from 2000 to 2016 and weather data from England, Wales, and the Netherlands.

The study’s methods could apply to other countries. Salmonella cases likely follow similar weather patterns worldwide.

Pandemic Lockdowns Reduced Social Skills in Children: New Research

June 25, 2025 by Lochlan DuVal Leave a Comment

Social skills may have suffered from COVID lockdowns.

The COVID-19 pandemic redefined daily life for many families. Schools and daycares closed, parents worked from home, and social distancing limited interactions. These changes disrupted early childhood development. Until recently, researchers had not studied how they affected social cognition.

A new study in Scientific Reports compared two groups of 3.5- to 5.5-year-olds. Researchers tested one group before the pandemic, and the other afterward.

Researchers focused on false-belief understanding (FBU), a key social cognition skill. FBU is the ability to recognize others’ different or incorrect beliefs.

Results showed that children tested after the pandemic performed worse on false-belief tasks. Even after controlling for age and language skills, the post-pandemic group struggled more. The effect was stronger for children from lower-income families.
