Know your epidemic, strengthen your response: Developing a new HIV surveillance architecture to guide HIV resource allocation and target decisions

To guide HIV prevention and treatment activities up to 2020, we need to generate and make better use of high quality HIV surveillance data. To highlight our surveillance needs, a special collection of papers in JMIR Public Health and Surveillance has been released under the title �Improving Global and National Responses to the HIV Epidemic Through High Quality HIV Surveillance Data.� We provide a summary of these papers and highlight methods for developing a new HIV surveillance architecture.
