WSSV was detected during routine testing of Pacific white shrimp (Litopenaeus vannamei) broodstock on a farm on Oahu, Hawaii as part of the Hawaii Department of Agriculture Shrimp Surveillance Certification Program (SSCP). At the time of sample collection, shrimp appeared stressed. All shrimp on the farm subsequently died. No shrimp remain on the farm, and all ponds recently used for shrimp production are presently drained and dried.

The Hawaii Department of Agriculture (HDOA) is currently conducting an epidemiological investigation of the event.
