Population Size Estimates Project: Deepening Our Knowledge to Provide Better Services

The BC Centre for Disease Control (BCCDC) has partnered with a number of key provincial stakeholders – including PAN and the BC Centre for Excellence in HIV/AIDS – and has contracted the Centre for Global Public Health (CGPH) at the University of Manitoba to develop population size estimates for key populations: men who have sex with men (MSM); people who use injection drugs (PWID); and sex workers affected by HIV and Hepatitis C within the 5 regional health authorities in British Columbia. These population estimates will inform organizational, regional and provincial level HIV and Hepatitis C program planning, implementation and evaluation to achieve the objectives outlined in the framework: From Hope to Health: Towards an AIDS-free generation.

This is important work. We know that these populations are disproportionately impacted by HIV and HCV in our province. What we don’t know is how many people there are in each of these priority populations across the province as a whole, regardless of their HIV or HCV status and where they live. Because we don’t understand the ‘total population size’ for these populations we are not able to adequate understand the HIV and HCV epidemics and plan services and programs for these groups of people.

During the Canada Post strike announced September 25, 2025, the following measures will be undertaken to minimize service disruption to BC-CfE clients and providers.

  • The BC-CfE Laboratory has transitioned to private courier for delivery of outgoing reports and documents. Results required urgently can be faxed upon request. (Lab Contact Information: Phone 604-806-8775; FAX 604-806-9463)
  • The BC-CfE Drug Treatment Program (DTP) will fax outgoing forms and documents to the provider’s office. (DTP Contact Information: Phone 604-806-8515; FAX 604-806-9044)
  • St. Paul’s Hospital Ambulatory Pharmacy has transitioned to private courier for delivery of medications. We recommend requesting medication at least 2 weeks in advance in case of delivery delays, particularly to rural/remote parts of BC. (Contact Information: Phone 1-800-547-3622; FAX 604-806-8675)

During the Canada Post strike, we recommend that documents be faxed or couriered to our sites, versus utilization of regular mail service

The BC-CfE Laboratory is streamlining reporting processes for certain tests in order to simplify distribution and record-keeping, and to ensure completeness of results. Beginning September 2, 2025, results for the ‘Resistance Analysis of HIV-1 Protease and Reverse Transcriptase’ (Protease-RT) and ‘HIV-1 Integrase Resistance Genotype’ tests will be combined into a single ‘HIV-1 Resistance Genotype Report’.
