A Few Facts About Common Viruses that NIH Studied with VFI Humic Acid®
Herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) are responsible for orofacial and genital herpes, respectively. Approximately 45 million Americans are serum-positive for genital herpes (type 2), with 20 million routinely exhibiting symptoms. It is believed that 80% of Americans are serum-positive for orofacial herpes (type 1), virtually all of whom occasionally exhibit symptoms. Roughly half of herpes simplex viruses are today Acyclovir-resistant. Human cytomegalovirus (HCMV) is pervasive in the U.S.: 90% of the urban U.S. population is serum-positive for HCMV, although infection in immunocompetent individuals is generally asymptomatic. Varicella zoster virus (VZV) is the cause of chickenpox in children and shingles in adults. Epstein-Barr virus (EBV) is the cause of infectious mononucleosis in adolescents and young adults.
Influenza A (INFL-A) (2 strains) and B (INFL-B) (1 strain) are routinely responsible for 20,000-30,000 deaths annually in the U.S., and well over 100,000 hospitalizations. Pandemics occur when the virus mutates radically. The 1918 “Spanish flu” [Influenza A(H1N1)] caused approximately 500,000 deaths in the U.S. and 50,000,000-100,000,000 worldwide. The 1957-58 “Asian flu” [influenza A(H2N2)] resulted in 70,000 deaths in the U.S., while the 1968-69 “Hong Kong flu” [influenza A(H3N2)] brought about 34,000 U.S. dead.
Pichinde virus (PICV) is a “New-World” (South American) arenavirus whose members are generally associated with rodent-transmitted disease in humans. Punta Toro virus (PUTV) is a South American phlebovirus of the Bunyaviridae family of viruses, and is transmitted by sand flies. Crimean-Congo, Rift Valley, and Hanta viruses are also members of this family.
