Epidemiology and Surveillance - epiSUMMARY March, 2020 SUMMARY
Reported cases of HIV infections
This report includes all laboratory-positive cases of HIV infections reported in Manitoba to the Epidemiology and Surveillance Unit.
For a case to be counted as a confirmed case of HIV infection, it must meet the provincial surveillance case definition as outlined in the Provincial Communicable Disease Management Protocol.
A new case of HIV is counted when an individual has a positive HIV antibody or viral DNA sequence test that is reported to the Public Health Surveillance System, Epidemiology and Surveillance, MHSAL for the first time. Only individuals who reside in Manitoba at the time of his/her diagnosis are counted.
Subsequent clinical consultation will confirm new cases and will help to exclude cases that were diagnosed in the province in previous years but that the Surveillance Unit was unable to exclude through its own investigations.
Until proper clinical consultation and case confirmation is performed, this report may display cases as under investigation. As clinical consultation is concluded, these cases will be re-classified either as new cases (as explained above) or as introduced cases, which are those that are new to the province, but had been previously diagnosed elsewhere. Additional information regarding case definitions can be found in the report Annual Statistical Update: HIV in Manitoba.

Number of reported cases of Human Immunodeficiency Virus infections per month in Manitoba,
January 01, 2015 to March 31, 2020.
In this graph, the monthly number of reported cases of Human Immunodeficiency 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 reported cases of Human Immunodeficiency 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 reported cases of Human Immunodeficiency 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.
