Recently, we released a warning of TiLV in Thailand including an improved semi-nested RT-PCR method for rapid detection. The Fish Health Platform in Centex, BIOTEC/Mahidol University has obtained positive test results for TiLV from other countries in Asia where it has not yet been reported. Further, the majority of our archived samples collected from previous disease outbreaks in several tilapia hatcheries in Thailand during 2012-2017 have tested positive for TiLV, indicating the presence of TiLV in Thailand even before the virus became known to science in 2013.
The origin of the disease is currently unknown, but many countries have been translocating tilapia fry/fingerlings prior to and even after the description of TiLV. Based on records we could obtain about such translocations, we have prepared a map that contains a list of 5 countries with confirmed reports of TiLV infections and a list of 43 other countries that we believe have imported tilapia that may have been infected with TiLV. We hope that widespread surveillance for TiLV in the Tilapia industry and in translocated fish will help reduce the impact and spread of this disease.
