Impact of herpesvirus infections in the future.
Numerous diverse, often opposing, trends will determine the frequency (and severity) of herpesvirus infections in the future. A major factor is the growing population of iatrogenically immunocompromised patients, accruing especially from large increases in organ and autologous bone marrow transplantation. Of even greater importance is the immense number of human immunodeficiency virus (HIV)-infected patients for whom herpesviruses may: (1) have been a cofactor in acquisition of HIV infection; (2) contribute to in vivo activation of HIV; (3) cause severe infections. Another factor influencing severe herpesvirus infections is the aging of populations in developed countries; this will be associated with a greater prevalence, and more morbid manifestations, of herpes zoster. Sociologic changes will also be important. The consequences of these, such as attempts to influence sexual practices, will be difficult to predict. Other changes, such as more frequent use of early child care facilities, will predictably lead to early acquisition of most herpesviruses, thereby decreasing the incidence of severe disease in adulthood. Factors that will reduce the incidence and/or severity of herpesvirus infections include vaccines (varicella, herpes simplex, cytomegalovirus); prophylactic strategies for immunocompromised hosts (passive immunization, antiviral drugs, blood product selection); more rapid and sensitive diagnostic methods; and suppressive or early antiviral therapy for common infections, such as genital herpes simplex and varicella.(ABSTRACT TRUNCATED AT 250 WORDS)
