Understanding barriers to effective management of influenza outbreaks by residential aged care facilities.

Autor(es): Huhtinen, Essi; Quinn, Emma; Hess, Isabel; Najjar, Zeina; Gupta, Leena

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 30537166
Resumen: OBJECTIVE: To identify the perceived barriers to the implementation of the Australian national guidelines on influenza outbreak management with Sydney Local Health District (SLHD) residential aged care facility (RACF) staff. METHODS: All SLHD RACFs were invited to participate in a telephone interview. The questionnaire collected information about demographic characteristics and participants' level of agreement with statements regarding perceived barriers to implementing the national guideli (mas)

The Effect of Individual Movements and Interventions on the Spread of Influenza in Long-Term Care Facilities.

Autor(es): Najafi, Mehdi; Laskowski, Marek; de Boer, Pieter T; Williams, Evelyn; Chit, Ayman; Moghadas, Seyed M

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 28538110
Resumen: BACKGROUND: Nosocomial influenza poses a serious risk among residents of long-term care facilities (LTCFs). OBJECTIVE: We sought to evaluate the effect of resident and staff movements and contact patterns on the outcomes of various intervention strategies for influenza control in an LTCF. METHODS: We collected contact frequency data in Canada's largest veterans' LTCF by enroling residents and staff into a study that tracked their movements through wireless tags and signal receivers. We anal (mas)

Autor(es): Blanco, Natalia; Eisenberg, Marisa C; Stillwell, Terri; Foxman, Betsy

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 27188950
Resumen: Influenza is a significant problem within hospitals, leading to extended hospital stays, excess morbidity and mortality, and economic loss. Prevention and control strategies are generally "bundled"; therefore, the individual effects of particular strategies and the value of combined strategies cannot be determined directly, making it difficult to discern the optimal strategy. To quantify the individual and joint effectiveness of several known influenza infection control measures used in gen (mas)

Assessing the Role of Voluntary Self-Isolation in the Control of Pandemic Influenza Using a Household Epidemic Model.

Autor(es): Zhang, Qingxia; Wang, Dingcheng

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 26295248
Resumen: In the absence of effective vaccines, antiviral drugs and personal protective measures, such as voluntary self-isolation, have been a part of preparedness plans for the next influenza pandemic. We used a household model to assess the effect of voluntary self-isolation on outbreak control when antiviral drugs are not provided sufficiently early. We found that the early initiation of voluntary self-isolation can overcome the negative effects caused by a delay in antiviral drug distribution wh (mas)

Evidence compendium and advice on social distancing and other related measures for response to an influenza pandemic.

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 24630149
Resumen: 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 (mas)

Antiviral prophylaxis and isolation for the control of pandemic influenza.

Autor(es): Zhang, Qingxia; Wang, Dingcheng
Fuente: Int J Environ Res Public Health;11(8): 7690-712, 2014 Jul 31.
MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 25089775
Resumen: 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 (mas)

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
Fuente: Ann Intern Med;160(10): 684-94, 2014 May 20.
MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 24842415
Resumen: 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 (mas)

Optimized strategy for the control and prevention of newly emerging influenza revealed by the spread dynamics model.

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 24392151
Resumen: 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 (mas)

Optimal strategies of social distancing and vaccination against seasonal influenza.

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 24245639
Resumen: Optimal control strategies for controlling seasonal influenza transmission in the US are of high interest, because of the significant epidemiological and economic burden of influenza. To evaluate optimal strategies of vaccination and social distancing, we used an age-structured dynamic model of seasonal influenza. We applied optimal control theory to identify the best way of reducing morbidity and mortality at a minimal cost. In combination with the Pontryagins maximum principle, we calcula (mas)

Selecting nonpharmaceutical interventions for influenza.

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 23231621
Resumen: Models of influenza transmission have focused on the ability of vaccination, antiviral therapy, and social distancing strategies to mitigate epidemics. Influenza transmission, however, may also be interrupted by hygiene interventions such as frequent hand washing and wearing masks or respirators. We apply a model of influenza disease transmission that incorporates hygiene and social distancing interventions. The model describes population mixing as a Poisson process, and the probability of (mas)

Estimating the value of containment strategies in delaying the arrival time of an influenza pandemic: a case study of travel restriction and patient isolation.

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 23030969
Resumen: With a simple phenomenological metapopulation model, which characterizes the invasion process of an influenza pandemic from a source to a subpopulation at risk, we compare the efficiency of inter- and intrapopulation interventions in delaying the arrival of an influenza pandemic. We take travel restriction and patient isolation as examples, since in reality they are typical control measures implemented at the inter- and intrapopulation levels, respectively. We find that the intrapopulation (mas)

On the roads to H1N1 pandemic era: drive safe and fearless using colour-coded masks.

Autor(es): Shahid, M

MEDLINE - Literatura Internacional en Ciencias de la Salud PMID: 22449531
Resumen: Notwithstanding the end of 2009 H1N1 pandemic, the threat for its revisit still persists and WHO has warned to remain vigilant. During that time the situation was more panicky than fatal. In this article, a suggestion to minimize the panic is provided by the usage of colour-coded masks and is proposed hereby as a "population segregation" approach in case of the revisit of H1N1 or similar threatening respiratory viral infections.
