A research team led by University of Washington scientists has found that several people in South and Southeast Asian countries working and living around monkeys have been infected with simian foamy virus (SFV), a primate virus that, to date, has not been shown to cause human disease. The findings provide more evidence that Asia, where interaction between people and monkeys is common and widespread, could be an important setting for future primate-to-human viral transmission. The study appears in the August issue of the journal Emerging Infectious Disease.
