Herpes simplex viruses (HSV) are ubiquitous pathogens which can be transmitted vertically causing significant morbidity and mortality in neonates. Neonatal HSV infection is infrequent with an incidence ranging from 1 in 3,500 to 1 in 20,000, depending on the population. Neonatal HSV infection is much more frequent in infants born to mothers experiencing a primary HSV infection with an incidence approaching 50%, while infants born to mothers experiencing recurrent HSV infection have an incidence of less than 3%. ⋯ Neonatal HSV infections, although being relatively uncommon, are associated with significant morbidity and mortality if unrecognised and specific treatment is delayed. Diagnosis relies on a high level of clinical suspicion and appropriate investigation. With early therapy, the prognosis for this infection is considerably improved.

This is Part II of a 2-part paper on fever of unknown origin (FUO) in children. It examines the aetiology and management of prolonged FUO in children and the difficulties in the management of FUO in children in developing countries. Part I of this paper discussed acute FUO in children and was published in the March 2001 issue of Paediatric Drugs. ⋯ Major difficulties in the management of FUO in children in developing countries include constraints in the availability and reliability of laboratory tests, cost, misuse of antibiotics and difficulties encountered in the diagnosis of malaria and typhoid fever. Malaria and typhoid fever are major aetiological considerations in both acute and prolonged FUO in children in developing countries. The newer quinolones may hold great promise for the treatment of serious bacterial infections, including meningitis, which are associated with prolonged FUO in developing countries.
