Influenza viruses are a leading cause of viralrespiratory illness, resulting in high levels of morbidity and mortality around the world every year (Luliano et al., 2018;Paget et al., 2019). Influenza viruses belong to theOrthomyxoviridaefamily, where four types A, B, C and D have ...
Patients with influenza B had similar rates of associated disease severity and ICU admission compared with patients with influenza A(H1N1) during two recent influenza seasons in Jerusalem, researchers reported. “The role of influenza B virus as a cause of severe disease and ICU admissions has been...

Since the 1970s influenza B has diverged into two lineages based on antigenicity, the Yamagata and Victoria lineages, with little or no serum cross-reactivity [4]. In contrast to the severity and epidemic potential of influenza A and B, influenza C infections induce only mild flu symptoms in...

but this seasonality is more variable in the tropics (see below). Two subtypes (A and B) have been described and may co-circulate, with one usually predominating in any given year. No obvious differences in disease severity or pathogenesis have been documented between these two subtype...
