    Virology Division, Department of Infectious Diseases and Immunology, Faculty of Veterinary Medicine, Utrecht University, 3584CL Utrecht, The Netherlands;
    Acute hemorrhagic conjunctivitis (AHC) is a painful, contagious eye disease, with millions of cases in the last decades. Coxsackievirus A24 (CV-A24) was not originally associated with human disease, but in 1970 a pathogenic "variant" (CV-A24v) emerged, which is now the main cause of AHC. Initially, this variant circulated only in Southeast Asia, but it later spread worldwide, accounting for numerous AHC outbreaks and two pandemics. Read More

    Phylodynamic Characterization of an Ocular-Tropism Coxsackievirus A24 Variant.
    PLoS One 2016 16;11(8):e0160672. Epub 2016 Aug 16.
    Department of Laboratory Medicine, Kaohsiung Medical University Hospital, Kaohsiung, Taiwan.
    Recent phylodynamic studies have focused on using tree topology patterns to elucidate interactions among the epidemiological, evolutionary, and demographic characteristics of infectious agents. However, because studies of viral phylodynamics tend to focus on epidemic outbreaks, tree topology signatures of tissue-tropism pathogens might not be clearly identified. Therefore, this study used a novel Bayesian evolutionary approach to analyze the A24 variant of coxsackievirus (CV-A24v), an ocular-tropism agent of acute hemorrhagic conjunctivitis. Read More

    A modeling and experiment framework for the emergency management in AHC transmission.
    Comput Math Methods Med 2014 16;2014:897532. Epub 2014 Feb 16.
    College of Information System and Management, National University of Defense Technology, Changsha 410073, China.
    Emergency management is crucial to finding effective ways to minimize or even eliminate the damage of emergent events, but there still exists no quantified method to study the events by computation. Statistical algorithms, such as susceptible-infected-recovered (SIR) models on epidemic transmission, ignore many details, thus always influencing the spread of emergent events. In this paper, we first propose an agent-based modeling and experiment framework to model the real world with the emergent events. Read More

    Coxsackievirus A24 variant (CVA24v) is a main causative agent of acute hemorrhagic conjunctivitis (AHC), which is a highly contagious eye infection. Previously it has been suggested that CVA24v uses sialic acid-containing glycoconjugates as attachment receptors on corneal cells, but the nature of these receptors is poorly described. Here, we set out to characterize and identify the cellular components serving as receptors for CVA24v. Read More

    Molecular characterization and phylogenetic study of coxsackievirus A24v causing outbreaks of acute hemorrhagic conjunctivitis (AHC) in Brazil.

    Background: Coxsackievirus A24 variant (CA24v) is the most prevalent viral pathogen associated with acute hemorrhagic conjunctivitis (AHC) outbreaks. Sixteen years after its first outbreak in Brazil, this agent reemerged in 2003 in Brazil, spread to nearly all states and caused outbreaks until 2005. In 2009, a new outbreak occurred in the northeast region of the country. Read More

    Stevens-Johnson syndrome in a juvenile systemic lupus erythematosus patient.

    Stevens-Johnson syndrome (SJS) is a severe and rare immune-mediated cutaneous reaction usually induced by drugs or infections. Few case reports have demonstrated SJS associated with adult systemic lupus erythematosus (SLE), and rarely in juvenile SLE (JSLE) patients. However, to the best of our knowledge the prevalence of this life-threatening cutaneous disease in the pediatric lupus population has not been studied. Read More

    [Comparison on the different thresholds on the 'moving percentile method' for outbreak detection].

    Shanghai Pudong New Area Center for Disease Control and Prevention, Shanghai 200136, China.
    Objective: To compare the different thresholds of 'moving percentile method' for outbreak detection in the China Infectious Diseases Automated-alert and Response System (CIDARS).

    Methods: The thresholds of P(50), P(60), P(70), P(80) and P(90) were respectively adopted as the candidates of early warning thresholds on the moving percentile method. Aberration was detected through the reported cases of 19 notifiable infectious diseases nationwide from July 1, 2008 to June 30, 2010. Read More

    An ex vivo model of coxsackievirus infection using multilayered human conjunctival epithelial cells.

    Department of Ophthalmology, University of Ulsan College of Medicine, Asan Medical Center, 388-1 Pungnap-2dong, Songpa-gu, Seoul 138-736, Korea.
    Background: The purpose of this study was to establish an ex vivo model of coxsackievirus infection since there seems to be no suitable disease model currently.

    Methods: Human conjunctival epithelial cells (HCECs) were cultured for 2 weeks in a serum-free air-liquid interface system to produce a multilayered structure. The cells were infected with coxsackievirus A24 (CVA24). Read More

    Understanding of acute hemorrhagic conjunctivitis (AHC) epidemics and outbreaks of Paederus spp keratoconjuctivitis, periorbital oedema ("Nairobi red eyes") and dermatitis.

    Medical Biosciences Department, University of Western Cape, Cape Town and Mbeya Referral Hospital.
    A recent epidemic of acute conjunctivitis in Dar es Salaam showed again the importance of developing a strong infectious diseases epidemiological surveillance network which is effective in minimising disease outbreaks. The current misunderstanding of diseases causation and management explains the repetitive nature of acute hemorrhagic conjunctivitis (AHC) in Dar es Salaam. This article aims at increasing public awareness by elaborating two diseases (Acute Hemorrhagic Conjunctivitis and Paederus spp keratoconjuctivitis, periorbital oedema-"Nairobi red eyes") confused by many as being associated with recurrent epidemics of conjunctivitis Dar es Salaam.

    An antiviral small-interfering RNA simultaneously effective against the most prevalent enteroviruses causing acute hemorrhagic conjunctivitis.
    Invest Ophthalmol Vis Sci 2011 Jan 5;52(1):58-63. Epub 2011 Jan 5.
    Department of Microbiology, University of Ulsan College of Medicine, Seoul, Korea.
    Purpose: Acute hemorrhagic conjunctivitis (AHC), a highly contagious eye disease, is caused primarily by either enterovirus 70 (EV70) or coxsackievirus A24 (CVA24) infection. Yet methods to prevent or cure AHC are not available. Recent evidence has shown that small-interfering RNAs (siRNAs), mediators of posttranscriptional gene knockdown, can act as effective antiviral agents. Read More
