Epidemiology and Surveillance - epiSUMMARY March, 2020 SUMMARY
Laboratory-confirmed cases of Hepatitis B Virus infections
This report includes all laboratory-positive and confirmed cases of hepatitis B virus infections reported in Manitoba to the Epidemiology and Surveillance Unit.
Confirmed cases of hepatitis B virus infection are classified in one of three categories: acute, chronic, and unspecified infections. The acute classification is used for new infections`. An infection lasting more than 6 months is considered chronic. Infections where this determination is not possible or the information is not yet available are classified as unspecified. For a case to be counted as a confirmed case of hepatitis B virus infection, it must meet the provincial surveillance case definition as outlined in the Provincial Communicable Disease Management Protocol.
Number of laboratory-confirmed cases of Hepatitis B Virus infections per year in Manitoba,
January 01, 2015 to March 31, 2020.
Types of laboratory-confirmed cases of
Hepatitis B Virus infections per year in Manitoba,
January 01, 2015 to
March 31, 2020.
Number of laboratory-confirmed cases of Hepatitis B Virus infections per month in Manitoba,
January 01, 2015 to March 31, 2020.
In this graph, the monthly number of laboratory-confirmed cases of Hepatitis B Virus 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.
Number of laboratory-confirmed cases of Hepatitis B Virus infections per month and by sex in Manitoba,
January 01, 2015 to March 31, 2020.
Similarly to the previous graph, the monthly number of laboratory-confirmed cases of Hepatitis B Virus 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.
