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.
Vulcheva se našla među određenim brojem inozemnih medicinara koji su uhićeni Libiji početkom 1999. godine, u svezi s velikom zarazom HIV-om u dječjoj bolnici u istočnoj gradu Benghazi nekoliko mjeseci ranije.
