The review analyzed data on the risks of influenza infection and severe course in tobacco smokers compared with non-smokers. The incidence of influenza in the Russian Federation in 2018 amounted to 26.33 per 100 000 people, and was 24% lower than the incidence in 2017 (34.86 per 100 000) due to the fact that in recent years the coverage of the population with preventive vaccinations has been significantly increased against the flu. Meta-analyzes shows that current smokers are more likely to get the flu than non-smokers. It is noted that smoking may increase the risk of hospitalization in smokers (OR 1.32–2.18 in various meta-analyzes) and former smokers after infection with the influenza virus. Tobacco has been found to increase the risk of death from influenza among older people. At the same time, there is a study of risk factors for severe outcomes in patients hospitalized with the 2009 H1N1 pandemic flu, in which smoking was not a risk factor for severe outcomes. During the influenza epidemic, smokers and former smokers should be given the flu shot and be informed of the risk of hospitalization, and they are also strongly advised to stop smoking.

Abstract The 2017–2018 North American influenza season caused more hospitalizations and deaths than any year since the 2009 H1N1 pandemic. The majority of recorded influenza infections were caused by A(H3N2) viruses, with most of the virus’s North American diversity falling into the A2 clade. Within A2, we observe a subclade which we call A2/re that rose to comprise almost 70 per cent of A(H3N2) viruses circulating in North America by early 2018. Unlike most fast-growing clades, however, A2/re contains no amino acid substitutions in the hemagglutinin (HA) segment. Moreover, hemagglutination inhibition assays did not suggest substantial antigenic differences between A2/re viruses and viruses sampled during the 2016–2017 season. Rather, we observe that the A2/re clade was the result of a reassortment event that occurred in late 2016 or early 2017 and involved the combination of the HA and PB1 segments of an A2 virus with neuraminidase (NA) and other segments a virus from the clade A1b. The success of this clade shows the need for antigenic analysis that targets NA in addition to HA. Our results illustrate the potential for non-HA drivers of viral success and necessitate the need for more thorough tracking of full viral genomes to better understand the dynamics of influenza epidemics.
