China reports first human H1N2v infection
China confirmed a laboratory‑verified human infection with influenza A(H1N2)v in a previously healthy boy aged two years and ten months who developed fever, paroxysmal cough and bronchopneumonia and recovered after treatment. Initial routine RT-PCR was negative, but next-generation sequencing of an oropharyngeal swab recovered the complete viral genome, which was a reassortant of swine H1N1, H1N2 and H3N2 lineages; influenza A was also found in a deceased pig at the household. Thirty close contacts tested negative and no sustained human-to-human transmission has been detected, so the finding is a surveillance alert.
