Vulcheva je bila među stranim zdravstvenim radnicima koji su početkom 1999. uhapšeni u Libiji u vezi s velikom zarazom HIV-om u jednoj dječjoj bolnici u gradu Bengaziju nekoliko mjeseci ranije.
Vulcheva was among a number of foreign health workers who were arrested in Libya in early 1999 in connection with a large-scale HIV infection in a children's hospital in the eastern city of Benghazi several months earlier.
