The objective of this study was to obtain a detailed picture of the transmission dynamics of seasonal influenza in Switzerland from 2003 to 2015. To this end, we developed a compartmental influenza transmission model taking into account social mixing between different age groups and seasonal forcing. We applied a Bayesian approach using Markov chain Monte Carlo (MCMC) methods to fit the model to the reported incidence of influenza-like-illness (ILI) and virological data from Sentinella, the Swiss Sentinel Surveillance Network. The maximal basic reproduction number, R0, ranged from 1.46 to 1.81 (median). Median estimates of...

Epidemics of seasonal influenza caused by H1N1pdm09, H3N2, and type B viruses occur throughout the world. Sporadic human H5 and H7N9 virus infections are also reported in particular regions. To treat influenza patients effectively with antivirals, sensitive and broad-reactive influenza rapid diagnostic tests (IRDTs) are required. Here, we tested the sensitivity of 23 IRDTs during the 2018–2019 influenza season for their ability to detect H1N1pdm09, H3N2, H5N1, H5N6, H7N9, and Victoria- and Yamagata-lineage type B viruses. All IRDTs detected all influenza A and B viruses tested but with different sensitivities. Severa...

Carter Roberts’ motorized wheelchair didn’t arrive until the day he died. It had been a long time coming and his parents had fought hard to get it. The chair cost more than $32,000 and the insurance companies wouldn’t cover it, so the family went to court. One insurer eventually agreed to pay for some components of the chair but not the whole thing. And then none of it mattered anyway. On Sept. 22, 2018, the Roberts’ doorbell rang and the chair was delivered. Also on Sept. 22, 2018, Carter died, just three months shy of his sixth birthday. He had been largely paralyzed for the final two years of his...

The objective of this theoretical study was to elucidate how these behavioral adaptations may affect the epidemiology of highly-pathogenic avian influenza in domestic poultry and the outcome of the implemented control policies. We studied a symmetric population game where the players are broiler poultry farmers at risk of infection and where the between-farms disease transmission is both environmental and mediated by poultry trade. Three types of farmer behaviors were modelled: vaccination, depopulation, and cessation of poultry farming. We found that the transmission level of the disease through trade networks has strong ...

NLM Informatics and Data Science Lecture Series Genomics-informed surveillance is now recognized as an important extension to the monitoring of rapidly evolving pathogens. Next generation sequencing has the ability to produce large amounts of data for tracking viruses of public health importance. Biomedical informatics approaches are able to facilitate the translation of these data into information for public health surveillance. Thus, epidemiologists can identify new outbreaks or monitor the course of a known epidemic by leveraging pathogen sequences (and corresponding metadata) generated from the clinical specimens of si...

Seasonal influenza results in approximately 3 –5 million cases of severe acute lower respiratory tract infection and about 250,000 to 500,000 deaths worldwide annually, thus posing a serious public health impact. Influenza A and B are the two major circulating viruses that cause epidemics worldwide, and both types exhibit an intriguing dynami c of infection pattern where different climate zones appear to have their own pattern of seasonal variation in incidence.1 Understanding and predicting the seasonality of influenza is crucial for optimizing public health decisions on vaccination strategy and healthcare resource preparedness.

Influenza infection is considered to be a serious respiratory disease in human. Annually, epidemics or even pandemics give rise to the frequent antigenetic variations of virus surface receptors, throughout the world. Bacterial infections followed by influenza are the biggest medical concerns associated with elevated mortality rates. These high morbidity and mortality rates, have become a priority in terms of health. Likewise, economic aspects of the issue have special importance also. In the present study, several articles have been investigated with regards to main key words including influenza A, secondary bacterial inf...

In this study we demonstrate the results of examination of 4,507 people aged over 14 years toward the influenza infection in the epidemic season of 2017/18. Most of the confirmed infections were reported in older people aged over 65, a high-risk population group. A low percentage of the vaccinated population may affect an increased number of confirmed influenza viruses in the elderly. The findings demonstrate a need to increase awareness of vaccination benefits, which is particularly essential to avoid influenza infection in the elderly.

This article provides a vision of integrated eco-friendly and sustainable behavioral communication change (BCC), biological control preparedness and resilience approaches, and innovations implementation in Saudi Arabia and GCC for the purpose of controlling the threat of Aedes-linked vector-borne viral diseases. Implementing innovative Aedes-linked arboviral preventive and resilient control measures is pivotal in improving community-based surveillance-response systems, BCC multidisciplinary and empowerment methods, and in enhancing community social mobilization and risk communication strategies. Moreover, boosting social, ...
