The most promising trends of using monoclonal antibodies (Mabs) in virology research of the viral hemorrhagic-fevers' agents are related with studying viral antigen structure and with developing diagnostic preparations for indicating and identifying infectious agents of the mentioned pathologies. Infections with the causative agents – Lassa virus and Ebola virus – can lead to death in more than 70% of hospitalized patients. Crimean-Congo agent was identical to a virus isolated from a patient in hemorrhagic fever (CCHF) is one of the most widely Congo and the name CCHF was adopted after that [5]. A hemorrhagic fever that had long been recognized in Asia came to international attention after a disease outbreak in the Crimean peninsula in 1944 and 1945 (36). These viruses live, for the most part, in rodents (e.g., rats and mice) and arthropods (e.g., mosquitoes and ticks). It is shown that primary screening of drugs against the pathogens of hemorrhagic fever with renal syndrome (HFV) may be performed, by using two approaches in estimating the suppression of plague formation and that of viral reproduction in the cultured cells. The resulting internal bleeding is usually not life-threatening, but the diseases can be. Viral haemorrhagic fever (VHF) is a general term for a severe illness, sometimes associated with bleeding, that may be caused by a number of viruses. VHFs are severe multisystem syndromes.
