Analysis of the situation for influenza in the world are drawn according to data published on the websites of the WHO, and the epidemic 2016 - 2017 in Russia - database «Research Influenza Institute» on the weekly morbidity, hospitalization, deaths from influenza in 61 observed the city. The influenza epidemic 2016 - 2017 started early, the duration of its in cities and in the country was longer and higher was the incidence of influenza and ARI in the cities and in the country than in the epidemic 2015 - 2016. But the epidemic of influenza A(H3N2) 2016 - 2017 there was less incidence morbidity at the peak, the frequency of hospitalization and, especially, mortality from influenza in the total population by 20 times, and in all age groups, especially among persons older than 65 years by 17.5 times, compared to the epidemic 2015 - 2016, caused by the pandemic virus influenza A(H1N1)pdm09. The peculiarities of the epidemic 2016 -17 according to the Federal districts, first of all, the absence of a second rise in the incidence of influenza in the South of Russia. The intensity of the epidemics of influenza A(H3N2) seasons 2016 - 17 and 2014 - 2015 - was average, and the epidemic A(H1N1) pdm09 2015 - 2016 - high. The case fatality rate in epidemics involving the influenza A(H3N2) remains significantly lower than in the epidemic caused by the pandemic virus influenza A(H1N1)pdm09.

National surveillance for Reye syndrome conducted during five years, including the period 1973-1974 and December 1976 through November 1980, has resulted in the reporting of more than 2,000 cases of Reye syndrome. The highest reported incidence of Reye syndrome occurred during years of primary influenza B and A (H1N1) activity; the reported incidence during one period of influenza A (H3N2) activity was somewhat lower. Regional outbreaks of Reye syndrome have been associated with influenza A (H1N1) and B but not with influenza A (H3N2). Cases of Reye syndrome in whites tend to be distributed throughout all age groups whereas a large percentage of cases in blacks have been reported in infants <1 year of age in three of the past four years. Nationally, there has been a decline in the case-fatality ratio in recent years.

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.

OBJETIVO: Analisar o perfil dos indivíduos acometidos pelo vírus Influenza A (H1N1), e o impacto vacinal nos grupos prioritários à vacinação. MÉTODOS: Estudo ecológico, observacional, de caráter retrospectivo, com população de indivíduos residentes na cidade de Maringá-PR e submetidos à internação por Influenza A entre 2009 e 2010. RESULTADOS: No ano de 2009, ocorreram 614 internações decorrentes de infecção pelo vírus Influenza A em Maringá-PR. A disponibilização da vacina fez com que o número de acometidos diminuísse para 169 em 2010, ocorrendo impacto vacinal nos seguintes grupos populacionais: gestantes, portadores de doenças crônicas e adultos de 20 a 39 anos. CONCLUSÃO: Identificou-se a necessidade de estender a faixa etária de vacinação para crianças de 2 a 4 anos e preenchimento dos impressos de vacinação dos indivíduos e grupos vacinados com maior rigor.

A vigilância de influenza baseada na detecção de casos de Síndrome Respiratória Aguda Grave (SRAG) em serviços de saúde é uma das estratégias a serem executadas por todos os hospitais em âmbito nacional, e tem como um dos objetivos avaliar o perfil de morbimortalidade associado aos vírus respiratórios. Dentre as ações realizadas incluem-se a busca ativa diária em unidade de internação, a notificação de casos ao Sistema de Informação de Agravos de Notificação, a coleta e encaminhamento de amostras biológicas para realização de exames laboratoriais específicos, a investigação de óbitos suspeitos e a orientação acerca de medidas de prevenção e controle da transmissão em ambiente hospitalar, colaborando para uma assistência médica qualificada. Em 2016 verificou-se uma maior circulação do vírus Influenza A H1N1, resultando em significativo impacto sobre serviços de saúde. Assim, visando a qualificação do sistema de vigilância de SRAG, o Nucleo de Vigilância Epidemiológica do HC- UNICAMP adotou um conjunto de intervenções junto aos diversos grupos de profissionais, especialidades médicas e setores do hospital: orientações diárias em enfermarias sobre protocolos de tratamento e investigação laboratorial vigentes, elaboração de informe técnico específico, reunião científica voltada a profissionais da saúde e organização dos insumos destinados à coleta de material biológico a ser examinado (“kit influenza”). Até a Semana Epidemiológica 30 de 2015 foram feitas 108 notificações com 27 (25%) amostras coletadas e 3 (11%) positivas, enquanto que em 2016, neste mesmo período, houve 232 notificações e 156 (67%) amostras coletadas com 27 (17%) positivas, mostrando aumento significativo após as intervenções.

Introduction. The seroprevalence study was performed in Vojvodina during May and June 2010 in order to asses the effects of the 2009 pandemic influenza A(H1N1)v epidemic on herd immunity. It was a part of the Serbian Ministry of Health funded nationwide study. Objective. Prevalence of antibodies against 2009 pandemic influenza A(H1N1)v was determined in a 1% sample of the population monitored for influenza-like illness and acute respiratory infections in Vojvodina through sentinel surveillance system. Methods. The study sample involved a total of 1004 inhabitants of Vojvodina. The control group consisted of randomly selected and age-adjusted 1054 sera collected in the pre-pandemic period. Sera were tested by the reaction of hemagglutination inhibition using influenza A/California/7/2009 (H1N1) antigen in dilution from 1:8 to 1:256. Antibody titers ?1:32 and ?1:8 were considered protective and diagnostic, respectively. Results. The differences between control and study sera in all age groups were significant for both diagnostic ?1/8 and protective titres ?1/32 of hemagglutination inhibition antibodies (chi square test, p<0.001). The highest percentage of seropositive subjects was registered in the age group 15-19 years followed by children aged 5-14 years. Both diagnostic and protective titres were about twice higher in the vaccinated as compared to the non-vaccinated group. There were no statistically significant differences in seroprevalence between seven districts of Vojvodina. Conclusion. The 2009 pandemic influenza A(H1N1)v epidemic significantly influenced the herd immunity in our population regardless of low immunization coverage with highest immunity levels in adolescents aged 15-19 years and with similar herd immunity levels in all the regions in the province six months after the outbreak.
