Getah Virus Infection among Racehorses, Japan, 2014.
Abstract: An outbreak of Getah virus infection occurred among racehorses in Japan during September and October 2014. Of 49 febrile horses tested by reverse transcription PCR, 25 were positive for Getah virus. Viruses detected in 2014 were phylogenetically different from the virus isolated in Japan in 1978.

This study discusses an outbreak of Getah virus infection among racehorses in Japan during 2014. The researchers found that 25 out of the 49 fever-stricken horses were positive for Getah virus, which was genetically different from the virus isolated in Japan in 1978.
Background and Methodology
- The study outlines an outbreak of Getah virus among racehorses in Japan that took place in September and October in 2014. This virus is known to cause fever and rash in horses, making it a significant consideration for equestrian health.
- Using reverse transcription PCR, a robust technique for detecting viral RNA, the researchers tested 49 horses that showed symptoms of fever. This method allowed them to determine if these febrile horses were infected with the Getah virus.
Results and Findings
- Upon testing, the researchers found that 25 of the 49 febrile horses were positive for the Getah virus. This confirmed the presence of an outbreak among the racehorses.
- Furthermore, they discovered that the Getah virus that was detected in 2014 was phylogenetically different from the one that was isolated in Japan in 1978. Hence, it is feasible to assume from the study that Getah virus has evolved over the years. In simpler terms, there are at least two genetically different strains of this virus.
Significance of the Study
- This study provides evidence of the presence of Getah virus in racehorses in Japan, offering researchers crucial data to understand the prevalence and progression of the disease.
- The detection of a phylogenetically different strain of Getah virus also provides insights into the evolution of the virus. This information can assist in developing appropriate tools for diagnosis, treatment, and prevention of the disease, taking into account the different strains that now exist.
