NIH highlights key strategies to combat H5N1

H5N1 avian influenza remains a low public health risk, according to NIH officials. However, vigilance and preventive measures are critical to managing its potential impact.

Dr. Jeanne M. Marrazzo and Dr. Michael G. Ison from NIAID propose a four-step strategy to address this evolving threat.

First, collaboration across medical and public health sectors is vital. This includes fostering trust among healthcare providers and individuals experiencing symptoms like conjunctivitis.

Second, robust surveillance and genomic sequencing are necessary to track virus mutations that could increase human transmissibility. Timely data sharing enhances understanding of the virus’s evolution.

Third, vaccine development is a priority. Existing vaccines effectively neutralize current strains, and ongoing advancements aim to strengthen public health defenses.

Finally, personal precautions are crucial. Poultry and dairy workers should use protective gear and follow safety guidelines to reduce exposure. “The No. 1 wildfire impact for ranchers is on their physical and mental health,” emphasized Dr. Ison.

The NIH urges communities and stakeholders to implement these strategies to manage H5N1 risks effectively. For more details, visit the NIH website.

Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
