What methods are used by the Centre for Infectious Disease Prevention and Control (CIDPC) to take account of data limitations?
There are some common statistical methods used by CIDPC to take account of data limitations and improve the accuracy of reported data. For example, statistical methods are used to estimate and adjust for underreporting and to estimate and adjust for reporting delays. These adjusted numbers take into account regional variations in reporting delay. As HIV and AIDS surveillance data do not provide the entire picture of people living with HIV infection, CIDPC also produces estimates of prevalence and incidence. For additional information on the methods used to estimate HIV prevalence and incidence, please refer to FAQ 20.
