New Research Finds Link Between Salmonella And Climate Change

June 30, 2025 by Lochlan DuVal

Climate change and salmonella are increasingly tied together.

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

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.

Malaria Research Now in Jeopardy as US Freezes Funding

June 23, 2025 by Lochlan DuVal

Malaria research may take a hit with new policies.

The Trump administration’s foreign aid freeze halted major malaria vaccine research. The USAID Malaria Vaccine Development Program (MVDP) told partners to stop work immediately. The freeze disrupts collaboration between U.S. and international researchers.

Affected teams included experts from Johns Hopkins University and the University of Oxford. The program aimed to reduce child deaths by developing improved malaria vaccines.

The funding freeze also halted medicine shipments and raised global health concerns. Malaria kills about 450,000 children under five in Sub-Saharan Africa each year.

Measles Cases Surging as Vaccinations Plummet: What You Should Know

June 18, 2025 by Lochlan DuVal

Measles cases are on the rise in the US.

A measles outbreak in West Texas has grown to 58 cases. In eastern New Mexico, eight people have also tested positive.

Measles spreads easily and can cause serious complications. Young children are especially at risk.

Officials say the actual number of infections is likely higher. They estimate between 200 and 300 cases have gone untested. Knowing the signs of measles can help limit its spread.

The U.S. Department of Agriculture has approved a new bird flu vaccine. Zoetis, the manufacturer, announced the approval last Friday.

The vaccine is for chickens and helps protect poultry flocks. It targets the H5N1 strain, which has infected 150 million birds. No existing vaccine fully matches this strain. Officials are now building a stockpile for livestock.

A new study links plastic takeout containers to a higher risk of heart disease. Researchers surveyed 3,179 people on plastic exposure and heart health. Frequent plastic use raised the risk of congestive heart failure by 13%.

The study suggests plastic exposure harms gut health and heart function. Researchers stress the need for further studies on plastic-related health risks.

An unknown illness has killed 53 people in northwest Congo, says WHO. Symptoms include fever, vomiting, diarrhea, muscle pain, headaches, and fatigue. Many deaths happened within 48 hours of symptoms appearing.

The cause of the outbreak is still unknown. Health officials are investigating to find the source and stop the spread.

New Study Reveals Colossal Surge in Chronic Fatigue after COVID-19

June 4, 2025 by Lochlan DuVal

Chronic fatigue is becoming increasingly common alongside COVID.

A new NIH-funded study found a sharp rise in ME/CFS cases. Researchers discovered that 4.5% of post-COVID patients met ME/CFS criteria. Only 0.6% of uninfected people met the same criteria.

ME/CFS, or Myalgic Encephalomyelitis Chronic Fatigue Syndrome, is a chronic illness. It often develops after infections and affects the nervous and immune systems. The condition causes severe fatigue that worsens after activity, called post-exertional malaise. Other symptoms include brain fog, dizziness, headaches, muscle weakness, and sleep problems.

New Research Shows Alarming HPV Cancer Rise in Men

New research is key to preventing HPV.

Most people know HPV can cause cervical cancer in women. However, many do not realize it also raises cancer risks for men.

A new survey from Ohio State University found widespread misunderstandings about HPV risks. Another study shows a major drop in cervical pre-cancer among likely vaccinated women. This progress follows nearly 20 years of U.S. HPV vaccine recommendations.

Despite this, low vaccination rates could allow preventable cancers to keep rising.

Vaccine Skepticism Is an Emerging Threat as Diseases Surge

May 28, 2025 by Lochlan DuVal

Vaccine skepticism plays a role in disease spread.

Dr. Lila Myrick had only read about measles in medical school. The disease was a medical concept, not a daily reality.

That changed in late January when a young girl arrived at her ER. She had the telltale rash of measles. The child had no immunity and a respiratory condition.

She became one of the first measles cases in Gaines County, Texas. This rural area is now the center of the largest U.S. measles outbreak in six years.

Last week, measles cases continued rising. Early this month, one unvaccinated child died. It was the first U.S. measles death in a decade.
