Popis: those agents which are available to the central nervous system (CNS)insignificant amounts for sustained periods. While these problems are apparent with a number of pathogens, RNA viral infections, with the notable excep­ tion of human immunodeficiency virus (HIV), have gen­ erally received less attention than DNA viruses. RNA viruses are unique in that they reverse the usual bio­ chemical DNA~ RNA~ protein sequence which occurs in higher life forms. In addition, RNA viruses precipitate diseases associated with significant mortality and morbi­ dity, such as dengue fever, Lassa fever, sandfly fever, Rift Valley fever, a variety of haemorrhagic fevers, and a number of encephalitic maladies such as Japanese B encephalitis (Johnson, 1984; Fisher-Hoch and Simpson, 1986). This latter infection is estimated to kill 30 000 people in the Far East each year, while sandfly fever is a major health problem in the Middle East. One notable advance in the treatment of these 'exotic' viral diseases was the development of ribavirin (1-[3-D­ ribofuranosyl-1,2,4-triazol-3-carboxamide) in the early seventies (Witkowski et al., 1972; L. Christensen and J.
