February 14, 2023

Scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have removed a major roadblock to better understanding of mpox (formerly, monkeypox). They developed a mouse model of the disease and used it to demonstrate clear differences in virulence among the major genetic groups (clades) of mpox virus (MPXV). The research, appearing in Proceedings of the National Academy of Science, was led by Bernard Moss, M.D., Ph.D., chief of the Genetic Engineering Section of NIAID’s Laboratory of Viral Diseases.
