Since the first discovery of severe fever with thrombocytopenia syndrome virus (SFTSV) in China in 2009, SFTSV has rapidly spread through other Asian countries including Japan, Korea, Vietnam and Pakistan in the chronological order. Taiwan reported its first discovery of SFTSV in the sheep and human in 2020, however the prevalence SFTSV in the domestic and wildlife animals and the geographic distribution of the virus within the island remain unknown. A total of 1324 animal samples, including 803 domestic ruminants, 521 wildlife animals and 47 tick pools were collected during March 2021 to December 2022 from 12 counties and one terrestrial island.
Overall, SFTSV RNA prevalence in ruminants was. Overall, 29.9% (240/803) of ruminants showed positive in SFTSV RNA. Sheep has the highest viral RNA prevalence of 60% (30/50), followed by beef cattle 28.4% (44/155), goat 28.3% (47/166), dairy cow 27.5% (119/432). The bovine as a total of dairy cow and beef cattle was 27.8% (163/587). The viral RNA prevalence in ticks was similar to those of ruminants at 27.7% (13/47) but wild animals exhibited much lower prevalence at 1.3% (7/521). Geographically the distribution of positivity was quite even, being 33%, 29.1%, 27.5% and 37.5% for the northern, central, southern and eastern Taiwan, respectively.
The nationwide study herein revealed for the first time the wide distribution and high prevalence of SFTSV in both domestic animals and ticks in Taiwan. Considering the high mortality rate in human, surveillance of other animal species, particularly those in close contact with human and instigation of protective measures for farmers, veterinarians, and especially older populations visiting or living near the farm or rural area should be prioritized.
