H1N1 pandemic: clinical and epidemiologic characteristics of the Canadian pediatric outbreak

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.

Influenza is a highly known contagious viral infection that has been responsible for the death of many people in history with pandemics. These pandemics have been occurring every 10 to 30 years in the last century. The most recent global pandemic prior to COVID-19 was the 2009 influenza A (H1N1) pandemic. A decade ago, the H1N1 virus caused 12,500 deaths in just 19 months globally. Now, again, the world has been challenged with another pandemic. Since December 2019, the first case of a novel coronavirus (COVID-19) infection was detected in Wuhan. This infection has risen rapidly throughout the world; even the World Health Organization (WHO) announced COVID-19 as a worldwide emergency to ensure human health and public safety. This review article aims to discuss important issues relating to COVID-19, including clinical, epidemiological, and pathological features of COVID-19 and recent progress in diagnosis and treatment approaches for the COVID-19 infection. We also highlight key similarities and differences between COVID-19 and influenza A to ensure the theoretical and practical details of COVID-19.
