Porcine reproductive and respiratory syndrome virus 2 in Europe: neither wild nor tamed
Contrary to expectations, PRRSV-2 vaccine-like strains exhibited transmission dynamics comparable to field strains. Their divergence, potential for adaptation, and reversion to virulence raise concerns about their long-term epidemiological and clinical impact. Given the scarcity of PRRSV-2 field strain reports in Europe, further surveillance and sequencing efforts are crucial to assess its true prevalence, evolutionary potential, and implications for swine health.
