Influenza viruses are capable of multiple reactivation after inactivation by UV radiation [34][35] or ionizing radiation. [36] If any of the eight RNA strands that make up the genome contain a lesion that prevents the replication or expression of essential genes, the virus cannot survive when it inf

Influenza A viruses are negative-sense, single-stranded, segmented RNA viruses. Several isoforms are labeled according to H value (hemagglutinin type) and N value (neuraminidase type).
