A new Respirovirus, Porcine parainfluenzavirus type 1 (PPIV-1) was first identified in 2013 in Hong Kong and later in the USA. Here, we report the first detection of PPIV-1 outside these two regions. Our research group has analyzed 15–15 (3–3 piglets from five litters) nasal swab samples obtained from three-week-old piglets originating from 22 Hungarian farms altogether from which only one farm was found to be positive. Subsequently, 20–20 nasal swab samples were obtained from 2, 4, 6 and 8-week-old piglets of this farm. Virus detection by qRT-PCR showed that although all investigated age groups were positive to PPIV-1, higher number of infected animals and higher viral loads were found among 4-year-old animals. Based on the phylogenetic analyses of partial F and L genes, the 3 Hungarian strains are almost identical and are highly similar to the very first PPIV-1 genome submitted from Hong Kong in 2013, whereas the overall genetic difference compared to the recently described North American isolates was around 10%.
