Adenovirus infections in Manitoba.

This review of adenovirus infections in Manitoba over a five-year period is introduced with a brief presentation on the structure-function relationships of the adenoviruses. Extensive research has resulted in the accumulation of a great deal of basic information, far surpassing our knowledge about the infections that these viruses produce in man. More research is needed on the epidemiological and clinical aspects of these diseases, including methods for prevention and treatment, and earlier methods of diagnosis.Features of 216 adenovirus respiratory infections diagnosed from 1963 to 1967 are reviewed and presented. All infections were diagnosed by showing a four-fold or greater increase. In addition, an adenovirus was isolated from many of the infections. These infections occurred every year in substantial numbers and they were seen during each month of the year, although they were more frequent and severe in the winter. Infants and younger persons were often affected. The most severe disease was a pneumonitis which occurred mainly in infants. Associated symptoms usually arose from the gastrointestinal tract, and were sufficiently common to indicate that one should suspect an adenovirus infection when respiratory and gastrointestinal symptoms occur together in a child.The possible role of adenoviruses in the etiology of other than respiratory diseases is discussed and the features of 96 possible non-respiratory infections are presented. Further work will be required to establish a definite etiologic role of the adenoviruses in most of these infections.

The elusive source of psittacosis in the Arctic.

Eskimos and Arctic Indians have a high incidence of psittacosis antibodies. The following Arctic birds were therefore examined in an endeavour to find the reservoir of infection: snow geese in their Arctic nesting grounds; migrating geese in the spring and in the fall; ptarmigan, raven, and snow bunting on the Arctic Circle in the late winter. Psittacosis virus was not recovered from any of the birds examined, but a percentage of migrating geese had psittacosis antibodies. The source of human and avian antibodies in the Arctic remains elusive.

Surveys of respiratory virus antibodies in an Arctic Indian population.

A study was undertaken to determine the etiological agents responsible for epidemics in a small and relatively isolated Arctic community.Three serological surveys were carried out over a four-year period employing complement fixation tests. Clinical information from the resident nurse was also available.The results indicated that of the two clinical epidemics of "influenza" which occurred during the period of study one was due to influenza virus type A; the other was unidentified. However, influenza virus type B affected approximately 30% of the population at some time during a two-year period without being clinically recognized. An epidemic affecting mainly children, which was clinically considered to be whooping cough, was probably caused by an adenovirus. A mumps epidemic with a high attack rate for all age groups which had occurred a few months prior to the first survey was confirmed. Sendai virus and psittacosis virus are probably endemic in this community.

Epidemiologic, clinical, laboratory, and therapeutic features of an urban outbreak of chancroid in North America.

An epidemic of 135 cases of chancroid occurred in Winnipeg, Manitoba, Canada, from July 1975 to September 1977. Probable contributing factors for development of chancroid lesions included male sex, lack of circumcision, and genital trauma. A previous history of venereal disease, sexual contact with a person from a bar or hotel in the core city area, unemployment, alcoholism, American Indian or Métis (mixed American Indian and Caucasian) race, and unstable domestic relationships were often accessory findings for infected patients. The tracing and treatment of lesion-free contacts of patients with chancroid may have contributed to the restriction of the outbreak to the core city area. Nineteen isolations of Hemophilus ducreyi were made, most by the use of a new selective medium. Treatment with a short course of penicillin antibiotics was ineffective for 10 of 16 patients, whereas an adequate course of sulfonamide or tetracycline antibiotics, combined when necessary with drainage of fluctuant inguinal abscesses, was effective therapy for most patients.
