Epidemiology and Surveillance - epiSUMMARY February, 2020 SUMMARY
Confirmed cases of Infectious Syphilis
This report includes all confirmed cases of Infectious Syphilis reported in Manitoba to the Epidemiology and Surveillance Unit. For a case to be counted as a confirmed case of Infectious Syphilis, it must meet the provincial surveillance case definition as outlined in the Provincial Communicable Disease Management Protocol.
Syphilis case counts depend on the timely reporting of cases by laboratories, physicians, and Medical Officers of Health as well as timely entry of case information into surveillance databases.
Infectious cases are those that have been diagnosed as being in one of the following stages: primary, secondary, early congenital, or early latent. Non-infectious stages are: tertiary, late congenital, and late latent.
Number of confirmed cases of Infectious Syphilis infections per year in Manitoba,
January 01, 2015 to February 29, 2020.
Number of confirmed cases of Infectious Syphilis infections per month in Manitoba,
January 01, 2015 to February 29, 2020.
In this graph, the monthly number of confirmed cases of Infectious Syphilis infections is presented as purple dots connected by lines. Monthly number of cases may be subject to large variations, which may make it difficult to spot trends in the data. For this reason, we also present a smoothed curve (solid purple line) for this data where the shaded area represents the 95% confidence interval generated from the smoothing procedure. The smoothed curve should unveil potential trends in the data presented.
NOTE: Infectious syphilis counts are affected by timely reporting and data entry. These delays, associated with high volume of cases due to outbreaks, may appear as an artificial and sudden drop in number of cases presented here for recent months. This fact is completed unrelated to how treatment is administered. Delays in updating surveillance systems are completely independent of client care, which is always a priority.
Number of confirmed cases of Infectious Syphilis infections per month and by sex in Manitoba,
January 01, 2015 to February 29, 2020.
Similarly to the previous graph, the monthly number of confirmed cases of Infectious Syphilis infections by sex is presented as purple squares for females, and orange triangles for males, both connected by lines with the corresponding color. Monthly number of cases may be subject to large variations, which may make it difficult to spot trends in the data. For this reason, we also present a smoothed curve for each data set along with their corresponding 95% confidence interval — as generated from the smoothing procedure — as a shaded area. Smoothed curves should help unveil potential trends in the data presented.
NOTE: This graph excludes cases where sex is unknown, if any. These cases will be included as data quality checks are performed and sex is identified.
