In 2014, the United States experienced an epidemic of acute flaccid myelitis (AFM) cases in children coincident with a nationwide outbreak of enterovirus D68 (EV-D68) respiratory disease. Up to half of the 2014 AFM patients had EV-D68 RNA detected by RT-PCR in their respiratory secretions, although EV-D68 was only detected in cerebrospinal fluid (CSF) from one 2014 AFM patient. Given previously described molecular and epidemiologic associations between EV-D68 and AFM, we sought to develop an animal model by screening seven EV-D68 strains for the ability to induce neurological disease in neonatal mice...

More than 2000 species of edible and/or medicinal mushrooms have been identified to date, many of which are widely consumed, stimulating much research on their health-promoting properties. These properties are associated with bioactive compounds produced by the mushrooms, including polysaccharides. Although β-glucans (homopolysaccharides) are believed to be the major bioactive polysaccharides of mushrooms, other types of mushroom polysaccharides (heteropolysaccharides) also possess biological properties. Here we survey the chemistry of such health-promoting polysaccharides and their reported antiobesity and antidiabetic properties as well as selected anticarcinogenic, antimicrobial, and antiviral effects that demonstrate their multiple health-promoting potential...

INTRODUCTION Leprosy, an infectious disease caused by Mycobacterium leprae, affects the nervous system, skin, internal organs, extremities and mucous membranes. Biological, social and environmental factors influence its occurrence and transmission. The first effective treatments appeared in 1930 with the development of dapsone, a sulfone. The main components of a control and elimination strategy are early case detection and timely administration of multidrug therapy. OBJECTIVES Review the history of leprosy control in Cuba, emphasizing particularly results of the National Leprosy Control Program, its modifications and influence on leprosy control...

The Philippines is a low middle-income, tropical country in Southeast Asia. Infectious diseases remain the main causes of morbidity, including tuberculosis. AIDS/HIV prevalence is still low at <1%, but is rapidly increasing. Fungal disease surveillance has not been done, and its burden has never been estimated. This becomes more important as the population of immunocompromised patients increases, drawn from patients with AIDS, TB, malignancies, and autoimmune diseases requiring chronic steroid use. Using the methodology of the LIFE program ( www...

Human infections with novel avian influenza A(H7N9)virus was an emerging infectious disease discovered in March, 2013. As of June30, 2016, 770 cases of H7N9 were reported in worldwide including 315 deaths with 40.9% of high case fatality rate. Yangtze River Delta and Pearl River Delta were the high-prevalence area. Formerly, the cases of H7N9 were concentrated on the municipalities. However, most of the case-patients were from smaller cities or rural areas nowadays. The H7N9 human infections mainly occurred in winter and spring every waves as similar as seasonal and H5N1 human infections...

Aquaculture is the fastest growing food-producing sector, and the sustainability of this industry is critical both for global food security and economic welfare. The management of infectious disease represents a key challenge. Here, we discuss the opportunities afforded by whole genome sequencing of bacterial and viral pathogens of aquaculture to mitigate disease emergence and spread. We outline, by way of comparison, how sequencing technology is transforming the molecular epidemiology of pathogens of public health importance, emphasizing the importance of community-oriented databases and analysis tools...

The recent outbreak of Zaire Ebola virus in West Africa altered the classical paradigm of vaccine development and that for emerging infectious diseases (EIDs) in general. In this paper, the precepts of vaccine discovery and advancement through pre-clinical and clinical assessment are discussed in the context of the recent Ebola virus, Middle East Respiratory Syndrome coronavirus (MERS-CoV), and Zika virus outbreaks. Clinical trial design for diseases with high mortality rates and/or high morbidity in the face of a global perception of immediate need and the factors that drive design in the face of a changing epidemiology are presented...

REVIEW

Systemically administered opioids are among the most powerful analgesics for treating severe pain. Several negative side-effects (respiratory depression, addiction, nausea, confusion) and the risk of opioid-induced hyperalgesia accompany opioid administration. One other side effect is the potential of opioids to suppress the immune response and thereby to increase the vulnerability for infections. Several studies have investigated the link between opioids and immunosuppression in vitro, in vivo as well as in patients with divergent results: Exogenous opioids such as morphine and fentanyl can impair macrophage and natural killer cell as well as T cell function and weaken the gut barrier in vitro and in animal studies...

Protecting the public from communicable infectious disease outbreaks is one of the most important, and most challenging, functions of public health. Foodborne outbreaks are not uncommon, and they can be especially difficult. This true story of the epidemiologic investigation into a typhoid fever outbreak illustrates the critical importance of timely reporting by front-line clinicians, extensive interprofessional teamwork, and statewide coordination.

A fundamental assumption in the use and interpretation of microbial subtyping results for public health investigations is that isolates that appear to be related based on molecular subtyping data are expected to share commonalities with respect to their origin, history and distribution. Critically, no approach currently exists for systematically assessing the underlying epidemiology of subtyping results. Our aim was to develop a method for directly quantifying the similarity between bacterial isolates using basic sampling metadata and to develop a framework for computing the epidemiologic concordance of microbial typing results...

The unprecedented scale of the Ebola outbreak in Western Africa (2014-2015) has prompted an explosion of efforts to understand the transmission dynamics of the virus and to analyze the performance of possible containment strategies. Models have focused primarily on the reproductive numbers of the disease that represent the average number of secondary infections produced by a random infectious individual. However, these population-level estimates may conflate important systematic variation in the number of cases generated by infected individuals, particularly found in spatially localized transmission and superspreading events...

BACKGROUND: Immigrants originating from intermediate and high HCV prevalence countries may be at increased risk of exposure to hepatitis C infection (HCV) in their countries of origin, however they are not routinely screened after arrival in most low HCV prevalence host countries. We aimed to describe the epidemiology of HCV in immigrants compared to the Canadian born population. METHODS: Using the reportable infectious disease database linked to the landed immigration database and several provincial administrative databases, we assembled a cohort of all reported cases of HCV in Quebec, Canada (1998-2008)...

Epidemiological studies and mouse models suggest that maternal immune activation, induced clinically through prenatal exposure to one of several infectious diseases, is a risk factor in the development of schizophrenia. This is supported by the strong genetic association established by genome wide association studies (GWAS) between the human leukocyte antigen (HLA) locus and schizophrenia. HLA proteins (also known in mice as the major histocompatibility complex; MHC) are mediators of the T-lymphocyte responses, and genetic variability is well-established as a risk factor for autoimmune diseases and susceptibility to infectious diseases...
