Fonte: Paediatr Respir Rev;16(2): 119-26, 2015 Mar.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 24630149
Resumo: The role of social distancing measures in mitigating pandemic influenza is not precisely understood. To this end, we have conducted a systematised review, particularly in light of the 2009 pandemic influenza, to better inform the role of social distancing measures against pandemic influenza. Articles were identified from relevant databases and the data were synthesised to provide evidence on the role of school or work place-based interventions, case-based distancing (self-isolation, quarant (mais)

Antiviral prophylaxis and isolation for the control of pandemic influenza.

Autor(es): Zhang, Qingxia; Wang, Dingcheng
Fonte: Int J Environ Res Public Health;11(8): 7690-712, 2014 Jul 31.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 25089775
Resumo: Before effective vaccines become available, antiviral drugs are considered as the major control strategies for a pandemic influenza. However, perhaps such control strategies can be severely hindered by the low-efficacy of antiviral drugs. For this reason, using antiviral drugs and an isolation strategy is included in our study. A compartmental model that allows for imported exposed individuals and asymptomatic cases is used to evaluate the effectiveness of control strategies via antiviral p (mais)

This paper describes 9 general hospital practices. METHODS: A questionnaire was distributed electronically to 12,612 members of the Association of Women's Health, Obstetric, and Neonatal Nurses (AWHONN). Respondents (N = 2,304) who reported working in obstetr (mais)

Health and economic benefits of early vaccination and nonpharmaceutical interventions for a human influenza A (H7N9) pandemic: a modeling study.

Autor(es): Khazeni, Nayer; Hutton, David W; Collins, Cassandra I F; Garber, Alan M; Owens, Douglas K
Fonte: Ann Intern Med;160(10): 684-94, 2014 May 20.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 24842415
Resumo: BACKGROUND: Vaccination for the 2009 pandemic did not occur until late in the outbreak, which limited its benefits. Influenza A (H7N9) is causing increasing morbidity and mortality in China, and researchers have modified the A (H5N1) virus to transmit via aerosol, which again heightens concerns about pandemic influenza preparedness. OBJECTIVE: To determine how quickly vaccination should be completed to reduce infections, deaths, and health care costs in a pandemic with characteristics simil (mais)

School closures during the 2009 influenza pandemic: national and local experiences.

Autor(es): Cauchemez, Simon; Van Kerkhove, Maria D; Archer, Brett N; Cetron, Martin; Cowling, Benjamin J; Grove, Peter; Hunt, Darren; Kojouharova, Mira; Kon, Predrag; Ungchusak, Kumnuan; Oshitani, Hitoshi; Pugliese, Andrea; Rizzo, Caterina; Saour, Guillaume; Sunagawa, Tomimase; Uzicanin, Amra; Wachtel, Claude; Weisfuse, Isaac; Yu, Hongjie; Nicoll, Angus
Fonte: BMC Infect Dis;14: 207, 2014 Apr 16.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 24739814
Resumo: BACKGROUND: School closure is a non-pharmaceutical intervention that was considered in many national pandemic plans developed prior to the start of the influenza A(H1N1)pdm09 pandemic, and received considerable attention during the event. Here, we retrospectively review and compare national and local experiences with school closures in several countries during the A(H1N1)pdm09 pandemic. Our intention is not to make a systematic review of country experiences; rather, it is to present the div (mais)

Fonte: PLoS One;9(1): e84694, 2014.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 24392151
Resumo: No matching vaccine is immediately available when a novel influenza strain breaks out. Several nonvaccine-related strategies must be employed to control an influenza epidemic, including antiviral treatment, patient isolation, and immigration detection. This paper presents the development and application of two regional dynamic models of influenza with Pontryagin's Maximum Principle to determine the optimal control strategies for an epidemic and the corresponding minimum antiviral stockpiles (mais)

Influenza outbreak control practices and the effectiveness of interventions in long-term care facilities: a systematic review.

Autor(es): Rainwater-Lovett, Kaitlin; Chun, Kevin; Lessler, Justin
Fonte: Influenza Other Respir Viruses;8(1): 74-82, 2014 Jan.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 24373292
Resumo: BACKGROUND: Evaluation of influenza control measures frequently focuses on the efficacy of chemoprophylaxis and vaccination, while the effectiveness of non-pharmaceutical interventions (NPI) receives less emphasis. While influenza control measures are frequently reported for individual outbreaks, there have been few efforts to characterize the real-world effectiveness of these interventions across outbreaks. OBJECTIVES: To characterize influenza case and outbreak definitions and control mea (mais)
