In conclusion, this outbreak investigation highlighted the importance of close collaboration between regional Public Health Services, the NVWA, the RIVM and diagnostic laboratories. Through a combined microbiological, epidemiological and source tracing approach, raw and undercooked beef products could be identified as the source of the S. Typhimurium outbreak. This outbreak yet again emphasizes the importance of awareness among consumers of the risk of infection when consuming or handling raw meat products. To increase transparency for consumers, we recommend adding warning labels to risk food products. Competing Intere...

Introduction Following the initial outbreak of A/H1N1pdm09 in 2009-10, periodic resurgences of the pandemic influenza virus have been reported from India with variable morbidity and mortality. 1, 2 We have earlier reported a recrudescence of A/H1N1pdm09 in 2012-13 in Kashmir region of the northern Indian state of Jammu and Kashmir where influenza is an important cause of acute respiratory infections during the winter months. 3, 4 During the initial months of 2015, an unusual increase in influenza A/H1N1pdm09 activity was observed thoughout India with more than 39000 cases and about 3000 deaths. 5 While the activity was us...

Conclusions: The HALR system can provide early reporting of specified pathogens according to test results, allowing for early detection of outbreaks and providing trends in infectious disease data. The results of this study show that the sensitivity and specificity of early disease detection can be increased by integrating the reported data in the HALR system with the cases’ clinical information (eg, diagnostic results) in EMRs, thereby enhancing the control and prevention of infectious diseases.

We refer transmission of infections in India which have implications for Pakistan [1]. As compared to Pakistan, the range and burden of infectious diseases are enormous in India including Severe Acute Respiratory Syndrome (SARS) contagion in 2002 –2003, Influenza A virus epidemic of 2006 (avian influenza), 2007 Equine influenza, Swine flu pandemic outbreaks in 2009 and 2014 [2]. Moreover, episodes of infectious diseases continue to rise in India, with a recent surge of chikungunya and dengue cases in 2016 [1].

We used structured questionnaires to collect data for the period January to December 2009 from participants who were involved in the backyard chicken farming network in three avian influenza hotspots (Ratchaburi, Suphan Bu...

AbstractHere, we present a comprehensive analysis of the H5N8/H5N5 highly pathogenic avian influenza (HPAI) virus strains detected in the Czech Republic during an outbreak in 2017. Network analysis of the H5 Hemagglutinin (HA) from 99% of the outbreak localities suggested that the diversity of the Czech H5N8/H5N5 viruses was influenced by two basic forces: local microevolution and independent incursions. The geographical occurrence of the central node H5 HA sequences revealed three eco-regions, which apparently played an important role in the origin and further spread of the local H5N8/HPAI variants across the country. A p...

Discussion will cover the differing evidence for each candidate vaccine demonstrating protection in animals against influenza viruses of widely divergent HA subtypes and groups, durability of protection, routes of administration including mucosal providing local immunity, and reduction of transmission. Human trials of some candidate universal vaccines have been completed or are underway. Interestingly, the HA stem, like nucleoprotein and matrix, induces immunity permitting some virus replication and emergence of escape mutants fit enough to cause disease. Vaccination with multiple target antigens will thus have advantages ...

Background: A large outbreak of influenza A(H1N1) was observed in 2009 and a huge number of people was infected and died during this pandemic event. The natural hosts of influenza virus are wild birds, however, the infection spreads mainly by human-to-human transmission once the viruses are adopted to humans. To develop health countermeasures, it is therefore important to identify how the viruses spread during the outbreak. In this talk, the transmission route of influenza A(H1N1) in 2009 in Japan was estimated based on three different information, namely geographic distance, domestic transportation network and genome information.
