Dr Seth has been working in the field of Virology since 1968. From 1970 to 1990, he worked on the role of viruses, particularly herpes simplex virus type 2 and Human papilloma viruses in the aetiopathogenesis of uterine cervical cancer in humans. In 1986, the Government of India identified his laboratory as a National HIV/AIDS Reference Centre. In 1987, he and his co-authors were the first ones in India to isolate HIV-1 from Indian patients infected with HIV. In the decade of 1990 several landmarks were achieved by their Reference Centre: development of indigenous ELISA kit for the detection of HIV-1 and 2 antibodies in infected individuals; identification of HIV-1 subtypes circulating in India. Presently his laboratory has been working on the development of Indian HIV-1 subtype C DNA vaccine. It is under preclinical trials in non-human primates for its efficacy.
In addition, they have been working on the evolution of Dengue viruses in Southeast Asia, particularly India. In 1996, North India (Punjab, Haryana, Rajasthan, Delhi and Uttar Pradesh) experienced a devastating epidemic of Dengue Hemorrhagic Fever (DHF) with high morbidity and mortality. In Delhi alone more than 10,000 individuals sought treatment in various hospitals of Delhi and 423 died. They identified the virus as Dengue type 2 genotype IV which replaced the existent Dengue type 2 genotype V strain circulating in the population since 1957. They also found that the current genotype IV strain was similar to the Dengue type 2 strain which had resulted in the DHF epidemics in the Seychelles (1977), Sri Lanka (1982), Somalia (1984), Pakistan (1994), Torres Straits (1996) and the Cook Islands (1997).
He has been able to introduce the Polymerase Chain Reaction as a rapid assay for the diagnosis of tuberculosis particularly extrapulmonary tuberculosis and HIV infection in newborns. Both these assays havebeen developed keeping in mind the Indian strains of the causative microorganisms, Mycobacterium tuberculosis and HIV.
