A Regional Webinar on Infection with Decapod Iridescent Virus 1 and Preparedness for Emerging Shrimp Diseases will be held via Zoom video conference on 10-11 September 2020. This consultation will discuss and plan actions for the prevention and management of this disease. Specific objectives are to:

• Provide updated technological information on DIV1.
• Advocate the strengthening of diagnostic capacities as well as active surveillance of DIV1 (to detect presence or absence of the virus).
• Formulate recommendations on sanitary measures (including biosecurity) for disease prevention.
• Promote emergency preparedness for emerging diseases.

Participation is open to all interested parties but registration is required.

The 85th edition of the Quarterly Aquatic Animal Disease Report contains information from nine governments. The foreword provides a disease advisory concerning decapod iridescent virus 1 (DIV1), an emerging threat to the shrimp industry.

Chinese Customs detected nucleic acid positives of COVID-19 on packaging containing frozen white leg shrimp produced in Ecuador on 3 July. Experts believe that the positive results do not represent infectious virus. However, in order to protect the health of consumers, the General Administration of Customs decided to suspend the registration of the relevant enterprises, suspend the import and export of the products of the relevant enterprises, and take measures such as the return of goods and destruction of goods temporarily detained.

This disease advisory describes the history, known host range, clinical signs and PCR detection methods for viral covert mortality disease (VCMD). Crustaceans currently known to be susceptible to VCMD include Penaeus vannamei, P. chinensis, P. japonicus, P. monodon, Macrobrachium rosenbergii, Procambarus clarkii, Exopalaemon carinicauda, Ocypode cordimanus, Diogenes edwardsii, Corophium sinense, Parathemisto gaudichaud and Tubuca arcuate. Fish species including Mugilogobius abei, Carassius auratus, and Paralichthys olivaceus may also be susceptible to the virus.

The 84th edition of the Quarterly Aquatic Animal Disease Report contains information from eleven governments. The foreword discusses meetings of the ad hoc Steering Committee of the Regional Collaboration Framework on Aquatic Animal Health in Asia and the Pacific.

Infection with DIV1 is an emerging disease in farmed Cherax quadricarinatus and Penaeus vannamei suffering a high mortality. This disease card provides information on signs of disease at pond and animal level (levels I - III diagnoses), the disease agent, known host range and distribution in the Asia-Pacific region, molecular diagnostic methods and provides key expert contact points.

This disease advisory describes the history, known host range, clinical signs and PCR detection methods for decapod iridescent virus 1 (DIV1). Preventative strategies are suggested. Currently known susceptible species of DIV1 include Penaeus vannamei, Macrobrachium rosenbergii, Exopalaemon carinicauda, M. nipponense, Procambarus clarkii, and Cherax quadricarinatus. Clinical signs of infected P. vannamei are not typical, including slightly reddish body, hepatopancreatic atrophy with colour fading, and empty stomach and guts.
