TL;DR: A global analysis of the spread of recently emerged SARS-CoV-2 variants and estimate changes in effective reproduction numbers at country-specific level using sequence data from GISAID is presented in this paper.

TL;DR: This study analyzes data from 19 countries, comprising some 70,000 hospitalized patients with severe H1N1 infection, to reveal risk factors for severe pandemic influenza, which include chronic illness, cardiac disease, chronic respiratory disease, and diabetes.

TL;DR: Despite the challenge still posed in the clinical separation of influenza from other respiratory infections, the global use of the new WHO case definitions should help determine global trends in the characteristics and transmission of influenza viruses and the associated disease burden.

TL;DR: Distinct influenza seasonality patterns, though complex, could be ascertained for most countries in the tropics and subtropics using national surveillance data and it may be possible to group countries into zones based on similar recommendations for vaccine timing and formulation.

TL;DR: Policy, availability, use and effectiveness of seasonal influenza vaccine in tropical and subtropical countries is reviewed.
