No specific international data are available for PID incidence worldwide. In 2005, however, the World Health Organization (WHO) estimated that approximately 448 million new cases of curable STIs occur annually in individuals aged 15-49 years. [45] Factors contributing to the difficulty of determining the actual worldwide incidence and prevalence of PID include the following [46] :

  • Nonrecognition of disease on the part of patients

  • Difficulties in obtaining access to care

  • The often subjective method of disease diagnosis

  • The lack of diagnostics and laboratory facilities in many developing countries

  • Underfunded and overstretched public health systems

Worldwide, WHO has determined that STIs rank in the top 5 disease categories for which adults seek care. Women in resource-poor countries, especially those in sub-Saharan Africa and Southeast Asia, experience an increased rate of complications and sequelae.

The annual rate of PID in high-income countries has been reported to be as high as 10-20 per 1000 women of reproductive age. Public health efforts implemented in Scandinavia to decrease the prevalence of STIs have been quite effective in reducing the incidence of PID. [47, 48]
