A virus that causes cold sores is reshaping its host’s genome within an hour of infection, a discovery that could help treat severe cases of the infection. Herpes simplex virus type 1 (HSV-1) infects billions of people worldwide without their knowledge, spreading through contact with other sores, saliva, or unbroken skin around the mouth. Once inside the cells, the virus replicates in the nucleus, causing the genome to become more tightly coiled. Researchers have now used advanced microscopy to visualize this process, providing new insights into how the virus manipulates its host’s genes. The findings could lead to new treatments for severe HSV-1 cases.
