FOR IMMEDIATE RELEASE LATEST REPORT ON WESTERN ENCEPHALITIS CASES IN ALBERTA The number of suspected cases of western encephalitis in Alberta horses has now reached 90, from a total of 12 two weeks ago. Dr. R. G. Christian, head of Alberta Agriculture's laboratory services branch, reports that 90 per cent of the 90 suspected cases have been diagnosed south of Calgary, mainly in the Lethbridge, Taber Bow Island, Brooks and Medicine Hat areas. The remaining 10 per cent have been scattered throughout the province with a small concentration in the Camrose area. Western encaphalitis,which can affect several species of animals and human beings, is a brain infection that is caused by a virus transmitted by mosquitoes. Typical symptoms include sleepiness, inco-ordination, fever and inability to eat. Because the virus has to be isolated or serological evidence of the specific infection has to be obtained, it takes several weeks before a tentative diagnosis can be confirmed. According to Dr. Christian, the outbreak of western encephalitis cases in Southern Alberta has slowed down considerably as a result of many horses having been vaccinated and the effect the cooler weather has had on mosquito activity. He says vaccines are still available, but that it is doubtful whether vaccinating so late in the mosquito season will be of much value. The mosquito population is already declining and a general frost could occur at any time to finish them off. Anyone who would like more information on the disease or on the advisability of vaccin- ating his horse should contact his local veterinarian. -30- 7.
