Porcine respirovirus 1, also known as Porcine parainfluenza virus 1 (PPIV‐1) was first identified in Hong Kong in 2013, later in the USA and most recently in Chile. Here, we report the first detection of PPIV‐1 outside these three regions. We screened 22 farms in Hungary by testing 15 nasal swab samples obtained from 3‐week‐old piglets (3 randomly chosen piglets from 5 litters in each farm). Only one farm was found to be positive. We subsequently sampled the positive farm by taking cross‐sectional 20 nasal swab samples from 2‐, 4‐, 6‐ and 8‐week‐old piglets. Virus detection by qRT‐PCR showed that although all investigated age groups were positive to PPIV‐1, a higher number of infected animals and higher viral loads were found among 4‐week‐old animals. Based on the phylogenetic analyses of partial F and L genes, the 3 Hungarian strains are genetically closely related to the very first PPIV‐1 strain identified in Hong Kong in 2013, whereas the overall genetic difference compared to the recently described North American isolates was around 10%.
