    "prose": "Researchers at Goethe University and Universitätsmedizin Frankfurt found that seminal fluid facilitates the uptake of the mpox virus into human cells. [^1]\n\nResearchers from Goethe University and the University Medical Center Frankfurt conducted a study on factors that facilitate Mpox virus spread. [^2]\n\nThe study found that naturally occurring protein fragments in semen form fiber-like structures that facilitate the docking of Mpox viruses to human cells. [^3]\n\nAn analysis of the seminal fluid showed that certain naturally occurring protein fragments are responsible for the effect of promoting viral uptake. [^4]\n\nIn 2023, a virus variant emerged that infected about 100,000 people in several African countries in the first half of 2024 alone and killed more than 200, primarily children and immunocompromised individuals. [^5]\n\nEmma Torbica, a doctoral student who conducted the experiments, stated that these results explain why sexual contact carries a particularly high transmission risk for the virus. [^6]\n\nSemen fluid can promote infection if it comes into contact with anal or genital mucous membranes where smallpox lesions have already formed. [^7]",
