NRCC 14106 of the Environmental Secretariat". Digitized edition from print produced by Environment Canada. Includes bibliographic references (p. 31-35). "Arthropod-borne viruses (arboviruses) constitute a recurrent hazard to human well-being throughout Canada during the warmer months of each year, at times of high prevalence of two categories of blood-sucking arthropods - culicine and aedine mosquitoes and ixodid ticks. Despite the low incidence of clinically manifest illnesses, principally encephalitis, which are due to arbovirus infections, the severity of symptoms attracts widespread public attention. Control of the spread of arbovirus infections has been promoted by knowledge of dose/effect relationships between arboviruses and (i) their arthropod vectors on the one hand; and (ii) human and other vertebrate reservoirs on the other hand. Data applicable to the Canadian environment relating to the spread of arboviruses by mosquitoes and ticks (paragraph 4. 1.3 of ACSCEQ Report No. 1) have been compiled in the present report."--Introduction, p. 7. gccst Viruses gccst Infectious diseases National Research Council Canada.
