Located 50 miles west of Fort Collins, Colorado, Colorado State University’s Mountain Campus in Pingree Park hosted the 23rd annual Rocky Mountain Virology Association meeting in 2023 with 116 participants. The 3-day event at the end of September consisted of 28 talks and 43 posters that covered the topics of viral evolution and surveillance, developments in prion research, arboviruses and vector biology, host–virus interactions, and viral immunity and vaccines. This year’s Randall Jay Cohrs keynote presentation covered the topic of One Health and emerging coronaviruses. This timely discussion covered the importance of global disease surveillance, international collaboration, and trans-disciplinary research teams to prevent and control future pandemics. Peak fall colors flanked the campus and glowed along the multiple mountain peaks, allowing for pristine views while discussing science and networking, or engaging in mountain activities like fly fishing and hiking.

Located on the traditional and ancestral homelands of the Arapaho, Cheyenne, and Ute Nations, Colorado State University’s Mountain Campus hosted the 25th Annual Rocky Mountain Virology Association meeting. The three-day event, held from 26 September to 28 September 2025, welcomed 152 participants focused on the following topics: viruses, prions, immunology, transmission, structural biology, and vector biology. This year’s Randall Jay Cohrs Keynote Presentation summarized ongoing research on viral glycoproteins in relation to viral entry and assembly. Understanding the role of viral glycoproteins is essential in vaccine and antiviral development for enveloped RNA viruses. Alongside rigorous scientific discourse and networking, attendees made the most of their time by hiking amidst beautiful fall colors, wildlife, and young aspens starting the forest anew. On behalf of the Rocky Mountain Virology Association, this report summarizes select presentations from the 25th annual meeting.

Located in the Rocky Mountains within the Arapahoe and Roosevelt National Forests, Colorado State University’s Mountain Campus in Pingree Park hosted the 24th Annual Rocky Mountain Virology Association’s meeting in 2024. A total of 165 participants, both regional and international, participated in the 3-day event, which consisted of 48 talks and 42 posters. These presentations discussed developments in prion research, current affairs, and novel tools in virology; investigated arboviruses and their vectors, as well as molecular foundations of viral interactions; and provided increased understanding of viral immunology and vaccines. This year’s Randall Jay Cohrs keynote presentation unveiled how viral infections disrupt intestinal homeostasis via Sting-dependent NK-kB signaling. This novel research demonstrated the importance of immunological pathways in the virus-induced disruption of homeostasis. Nested in the valley of the Rocky Mountains, participants could enjoy the fall colors and partake in hiking and fishing all while discussing science and networking amongst a variety of scientists. This report encapsulates selected presentations from the 24th Annual Rocky Mountain Virology Association meeting.
