“…15,16,31,64 EBV has been considered to be monoclonal on the basis of several repeated analyses in HVLL, and expresses a type II latency of EBV infection, with EBER expressed in all cases. 2,10,23,36,43,48,53,54,64 HV symptoms are associated in some of these patients with hypersensitivity to mosquito bites (HMB), 13,17,22,24,63 which is an EBV-related disease exclusively reported in restricted areas such as Asia and Mexico, and characterized by an indurate, clear, or hemorrhagic bulla at the mosquito bite site that develops into necrosis or an ulcer, and heals with residual scarring. In contrast to HV, HMB frequently presents with high fever and general malaise and lymphadenopathy, hepatosplenomegaly, and even renal failure.…”
