Abstract: Resumen El desarrollo de la pandemia de la covid-19 ha motivado un renovado interés por la gripe de 1918-1919 para buscar elementos que facilitaran la comprensión de la experiencia presente, pero también como oportunidad para reevaluar la grave crisis sanitaria del siglo XX a la luz de lo que estamos viviendo. En este contexto y con ese objetivo se inserta esta reflexión histórica sobre estos dos fenómenos pandémicos, que muestra los paralelismos existentes y la necesidad de una toma (more)

Abstract: RESUMEN Introducción: La influenza tiene elevado impacto en la mortalidad humana y en Cuba la categoría influenza y neumonía ocupa el cuarto lugar entre sus causales generales. En los países templados, con marcada estacionalidad, esto se capta con modelos estadísticos, tarea que se dificulta en el trópico y pendiente en Cuba por la ausencia de igual definición estacional. Objetivo: Estimar el impacto histórico de la influenza tipo A y B y los subtipos A(H3N2) y A(H1N1) sobre la (more)

MEDLINE - International Database for Medical Literature PMID: 31617654
Abstract: OBJECTIVE: To explore factors associated with adverse outcomes during influenza outbreaks in residential aged care facilities. METHODS: A retrospective cohort study of all outbreaks reported to three Sydney metropolitan Public Health Units during 2017. RESULTS: A total of 123 outbreaks affected 1,787 residents and 543 staff. Early notification to a Public Health Unit was associated with shorter outbreak duration (p<0.001; B=0.674). Resident attack rates and resident mortality rates were low (more)

Quadrivalent versus trivalent influenza vaccine: clinical outcomes in two influenza seasons, historical cohort study.

Author(s): Shasha, D; Valinsky, L; Hershkowitz Sikron, F; Glatman-Freedman, A; Mandelboim, M; Toledano, A; Paran, Y; Ben-Ami, R; Goldman, D

MEDLINE - International Database for Medical Literature PMID: 31108229
Abstract: OBJECTIVES: The quadrivalent influenza vaccine (QIV) contains two influenza B antigens (one of each B lineage), while the trivalent vaccine (TIV) contains solely one. As a result, a mismatch between the circulating B lineage and the lineage in the TIV occurs frequently. We aimed to compare the frequency of clinically significant outcomes in a large cohort of vaccinees receiving either TIV or QIV. METHODS: Historical cohort study of all inactivated influenza vaccinees (aged 3 years and olde (more)

One hundred years ago in 1919: New Zealand's birth reduction shock associated with an influenza pandemic.

Author(s): Wilson, Nick; Turner, Nikki; Baker, Michael G
Source: N Z Med J;132(1507): 57-62, 2019 12 13.
MEDLINE - International Database for Medical Literature PMID: 31830017
Abstract: AIM: We aimed to conduct a preliminary analysis of any association between the 1918 influenza pandemic and its impact on birth rates in New Zealand. METHODS: Official data covering the period 1910 to 1930 were sourced from multiple New Zealand Yearbooks. Estimates were made of the size of the natality impacts and estimates made of the potential causes. RESULTS: In 1919 there were 3,756 fewer non-Maori and 239 fewer Maori births than the pre-pandemic year of 1917, with these representing red (more)

Abstract: To determine the seroprevalence and seroconversion of avian influenza virus (AIV) antibodies in poultry workers, we conducted a seroepidemiologic study in 7 areas of China during December 2014-April 2016. We used viral isolation and reverse transcription PCR to detect AIVs in specimens from live poultry markets. We analyzed 2,124 serum samples obtained from 1,407 poultry workers by using hemagglutination inhibition and microneutralization assays. We noted seroprevalence of AIV antibodies fo (more)

Abstract: A 17-month-old boy in India with severe acute respiratory infection was laboratory confirmed to have avian influenza A(H9N2) virus infection. Complete genome analysis of the strain indicated a mixed lineage of G1 and H7N3. The strain also was found to be susceptible to adamantanes and neuraminidase inhibitors.

MEDLINE - International Database for Medical Literature PMID: 31581263
Abstract: There was a pandemic of influenza A (H1N1) in 2009; in Korea, there was also an H1N1 epidemic in 2016. We aim to investigate whether survival had improved in the setting of recent advances in intensive care unit (ICU) management. We conducted a retrospective analysis of acute respiratory failure patients with H1N1 influenza pneumonia in 2016 and 2009 respectively at two tertiary referral hospitals in Korea. A total of 28 patients were treated in 2016, and 34 in 2009. There was no significan (more)

Abstract: During October 2011-September 2014, we screened respiratory specimens for seasonal and avian influenza A(H5N1) virus infections among outpatients with influenza-like illness and inpatients with severe acute respiratory infection (SARI) in East Jakarta, an Indonesia district with high incidence of H5N1 virus infection among poultry. In total, 31% (1,875/6,008) of influenza-like illness case-patients and 15% (571/3,811) of SARI case-patients tested positive for influenza virus. Influenza A(H1 (more)
