Scientific session 11

Viral infections can also occur during pregnancies and it is the major cause for of maternal and fetal morbidity and mortality. Infections can develop in the neonate transplacentally, perinatally (from vaginal secretions or blood), or postnatally (from breast milk or other sources). Traditionally, the only viral infections of concern during pregnancy were those caused by rubella virus, CMV, and herpes simplex virus (HSV). Other viruses now known to cause congenital infections include parvovirus B19 (B19V), varicella-zoster virus (VZV), West Nile virus, measles virus, enteroviruses, adenovirus, human immunodeficiency virus (HIV), and Zika virus.

Scientific Session 9

Session 09: Tumour Virology
Viruses are also known to induce cancer in humans. The viruses that cause cancer are termed as oncovirus. Many of these viral oncogenes have been discovered and identified to cause cancer. The main viruses associated with human cancers are human papillomavirus, hepatitis B and hepatitis C virus, Epstein-Barr virus, human T-lymphotropic virus, Kaposi's sarcoma-associated herpesvirus (KSHV) and Merkel cell polyomavirus.

Scientific Session 8

The distribution of viruses and viral infections across the globe is referred as epidemiology. Most epidemiologic studies of infectious diseases have concentrated on the factors that influence acquisition and spread, because this knowledge is essential for developing methods of prevention and control. Historically, epidemiologic studies and the application of the knowledge gained from them have been central to the control of the great epidemic diseases, such as cholera, plague, smallpox, yellow fever, and typhus.

Scientific Session 7

Session 07: Emerging Viruses
New Viruses keep emerging each day and the term emerging virus is used to indicate the viruses that have been identified recently. Recent advances have occurred in the identification and understanding of new hantaviruses in the Americas, causing an acute respiratory disease. Although new viruses are discovered almost yearly (e.g., Australian bat lyssavirus), other "older" viruses (e.g., dengue) are re-emerging, infecting millions of people every year with significant mortality.

Scientific Session 6

Session 06: Host Defences
When the immune system encounters a virus it produces specific antibodies that bind to it and eliminate it. Antibodies present in the blood samples may be used to determine if the person has been exposed to the infection. The second line of defense is by cell-mediated and humoral immune response by the production of B cells and T helper cells. The immune system retains the memory of the infection hence a second encounter of the same virus is prevented and eliminated.

Scientific Session 5

Viruses are classified based on their morphology, chemical composition and mode of replication. Viruses that infect humans are currently grouped intoclassification and nomenclature of viruses, including the chemical composition and configuration of the nucleic acid, whether the genome is monopartite or multipartite.
21 families. Two main schemes are used for the classification of viruses by the International Committee on Taxonomy of Viruses (ICTV) system and Baltimore classification system. Based on which viruses are placed under 7 groups. Aside from physical data, genome structure and mode of replication are criteria applied in the

  • DNA Viruses
  • RNA Viruses
  • Reverse Transcribing Viruses
  • Bacterial Viruses
  • Subviral Agents

Scientific Session 4

Session 04: Viral Isolation
Viral isolation is the most important step in the diagnosis of infection. Usually, the virus is isolated from the blood, serum and fluid samples collected from the infected patients. Most of the viruses have RNA as the genetic material. Hence several serological methods have been identified for the purification of RNA from the sample and their cultivation.

  • Infectivity Assays
