“…The review is not exhaustive and does not discuss a number of important emerging neurotropic pathogens such as chikungunya virus, Toscana virus and tick-borne encephalitis virus. Nor does it discuss the 25-year global campaign to eradicate poliovirus that has seen spectacular successes including the announcement in 2012 that India has now been free of polio for nearly 2 years [42]. Successes like this have been tempered by the persistent difficulty controlling polio in the three remaining endemic countries: Nigeria, Pakistan and Afghanistan [43,44].…”

Purpose of reviewThis review highlights research and development in the field of emerging viral causes of encephalitis over the past year. Recent findingsThere is new evidence for the presence of henipaviruses in African bats. There have also been promising advances in vaccine and neutralizing antibody research against Hendra and Nipah viruses. West Nile virus continues to cause large outbreaks in the United States, and long-term sequelae of the virus are increasingly appreciated. There is exciting new research regarding the variable susceptibility of different brain regions to neurotropic virus infection. Another cluster of solid organ transplant recipients developed encephalitis from organ donor-acquired lymphocytic choriomeningitis virus. The global epidemiology of Japanese encephalitis virus has been further clarified. Evidence continues to accumulate for the central nervous system involvement of dengue virus, and the recent deadly outbreak of enterovirus 71 in Cambodian children is discussed. SummaryIn response to complex ecological and societal dynamics, the worldwide epidemiology of viral encephalitis continues to evolve in surprising ways. The articles highlighted here include new research on virus epidemiology and spread, new outbreaks as well as progress in the development of vaccines and therapeutics.

“…In 2011 China reported polio outbreak after a gap of ten years, which was found to be related to wild poliovirus circulating in Pakistan [11]. Thus if a polio free country becomes re-infected as Bangladesh and China did in the past, this could spread like wild fire.…”

Abstract:As per recommendation from WHO, Bangladesh began a comprehensive plan for AFP (Acute Flaccid Paralysis) and EPI (Expanded Program on Immunisation) disease surveillance from 1997. The country has been maintaining key performance indicators for AFP surveillance for the past ten years. Bangladesh has been declared polio free on 27 th March 2014. The aim of this paper is to evaluate and describe results of AFP surveillance indicators for Bangladesh showing the progress made over time as well as identifying areas, which needs further improvements to maintain the polio free status. This retrospective study has been conducted using the surveillance data routinely collected from AFP cases on demographic characteristics and clinical & laboratory examination. Data of 7480 children less than 15 years old reported between January 2011 to December 2015 have been included in this study. Among all reported cases 59.22% cases were male children with a male: female ratio of 1.45:1. 54% of the reported AFP cases within the study period belong to 1-4 years of age. Among all reported cases, 56% have been diagnosed with Guillain-Barre Syndrome or GBS. Annual Non-Polio AFP rate has been successfully achieved nationally for each study year. Completeness and Timeliness of passive reporting from facilities have been satisfactory. 98% or more of all reported AFP cases within the study period has been investigated within 48 hours of notification. For over 95% of all reported AFP cases two stool samples were collected within 14 days of case reporting. 60 plus day follow up has been performed for at least 99% reported AFP cases within the study period. All epidemiological and laboratory surveillance indicators were successfully met for AFP surveillance. However it is important for Bangladesh to maintain long-term AFP case based surveillance along with introduction of Environmental surveillance due to the risk of poliovirus importation before global polio eradication.

“…Environmental surveillance has been widely used for the detection of disease outbreaks, in disease reduction and as indicators for early warning systems and for source attribution [180,181,182,183,184,185,186]. The institution and data source platform are summarized into the Table 3.…”

Surveillance is critical to understanding the epidemiology and control of infectious diseases. The growing concern over climate and other drivers that may increase infectious disease threats to future generations has stimulated a review of the surveillance systems and environmental data sources that might be used to assess future health impacts from climate change in Europe. We present an overview of organizations, agencies and institutions that are responsible for infectious disease surveillance in Europe. We describe the surveillance systems, tracking tools, communication channels, information exchange and outputs in light of environmental and climatic drivers of infectious diseases. We discuss environmental and climatic data sets that lend themselves to epidemiological analysis. Many of the environmental data sets have a relatively uniform quality across EU Member States because they are based on satellite measurements or EU funded FP6 or FP7 projects with full EU coverage. Case-reporting systems for surveillance of infectious diseases should include clear and consistent case definitions and reporting formats that are geo-located at an appropriate resolution. This will allow linkage to environmental, social and climatic sources that will enable risk assessments, future threat evaluations, outbreak management and interventions to reduce disease burden.
