The Asia-Pacific Congress of Medical Virology (APCMV) is a triennial international meeting that focuses on diagnostic, public health, research and clinical virology, with emphasis on the Asia Pacific region. The aim of this conference is to foster collaboration and information sharing of the latest research in the field of virology pertaining to medically important viruses and treatments against them. Including the most recent COVID-19 pandemic, many emerging virus infections have been centered in the Asia Pacific region, and the breaking down of boundaries between civilization and wildlife only serves to accelerate that. Therefore, it is vital for the countries in the region to develop a strong public health, diagnostic and research base to address these problems. Hence the APCMV congress series was started to enable the review, sharing and discussion in each of these areas for forming a strong foundation against the management of medically important viruses.
