Simbu serogroup viruses induce acute clinical diseases and abnormal courses of pregnancies in livestock. In Israel, two members of this serogroup, namely Akabane virus (AKAV) and Shuni virus (SHUV), were recently detected and, in Europe, Schmallenberg virus (SBV) poses a threat to ruminants. To address this emerging problem, a universal S-segment-based real-time RT-PCR assay (Uni-S) for the detection of Simbu serogroup viruses was established, which, additionally, enabled species identification of the detected viruses by subsequent sequencing...

Late presentation to human immunodeficiency virus (HIV) care is an important concern for clinical outcomes and HIV prevention. Significant proportions of HIV-diagnosed persons are not timely linked to care following HIV diagnosis. We implemented and evaluated an intervention to link to care persons never in HIV care (NIC). Disease intervention specialists (DIS) traced persons presumed to be NIC since HIV diagnosis, offered them assistance with linkage to care, and elicited reasons for NIC. We examined the overall outcomes of the intervention and reasons for NIC...

BACKGROUND: Talaromyces marneffei (T. marneffei) is a thermal dimorphic pathogenic fungus that often causes fatal opportunistic infections in human immunodeficiency virus (HIV)-infected patients. Although T. marneffei-infected cases have been increasingly reported among non-HIV-infected patients in recent years, no cases of T. marneffei infection have been reported in pulmonary sarcoidosis patients. In this case, we describe a T. marneffei infection in an HIV-negative patient diagnosed with pulmonary sarcoidosis...

Migrants, defined as individuals who move from their country of origin to another, account for 40% of newly-diagnosed cases of human immunodeficiency virus (HIV) in the European Union/European Economic Area (EU/EEA). Populations at high risk for HIV include migrants, from countries or living in neighbourhoods where HIV is prevalent, and those participating in high risk behaviour. These migrants are at risk of low CD4 counts at diagnosis, increased morbidity, mortality, and onward transmission. The aim of this systematic review is to evaluate the effectiveness and cost-effectiveness of HIV testing strategies in migrant populations and to estimate their effect on testing uptake, mortality, and resource requirements...

Dengue virus (DENV) infection causes various clinical presentations, including asymptomatic infection, dengue with or without warning signs and severe dengue. An early and accurate diagnosis of DENV infection during the first few days of illness supports clinical management and significantly reduces dengue-associated mortality and morbidity. However, it is very difficult to confirm DENV infection in endemic regions without qualified dengue diagnostic laboratories. In this study, we evaluated the performance of two commercially available rapid diagnostic tests (RDTs) using serum samples collected in the Solomon Islands during the 2013 DENV-3 outbreak...

RATIONALE: Dengue fever is a notable emerging infectious disease that is now seen worldwide, with an estimated incidence of approximately 390 million cases per year. Although ocular complications are uncommon among dengue fever-infected patients, caution is needed to prevent vision loss. Here we report a potentially serious sight-threatening complication of dengue fever, dengue fever-associated necrotizing scleritis. PATIENT CONCERNS AND DIAGNOSIS: After being bitten by mosquitoes, a 60-year-old Japanese female exhibited positive serologic tests of immunoglobulin M and G enzyme immunoassays for dengue viral infection along with a decrease of leukocytes and platelets...

INTRODUCTION: The World Health Organization recommends point-of-care (POC) lateral flow urine lipoarabinomannan (LF-LAM) for tuberculosis (TB) diagnosis in selected human immunodeficiency virus (HIV) positive people. South Africa had 438 000 new TB episodes in 2016, 58.9% of which were contributed by HIV-positive people. LF-LAM is being considered for scale-up in South Africa. METHODS: We estimated the costs of using LF-LAM in HIV-positive adults with CD4 counts  150 cells/μl enrolled in the TB Fast Track Trial in South Africa...

The major impacts of bovine viral diarrhoea (BVD) on cattle health and production have prompted many countries to embark on national elimination programmes. These programmes typically involve identifying and removing persistently infected (PI) cattle in infected herds and implementing biosecurity measures, such as pre- or post-movement testing. In order to design a systematic national control programme to eliminate BVD in New Zealand, that achieves the greatest benefits to the industries at the lowest cost to individual farmers, an accurate understanding is necessary of the epidemiology, economics and social motivation for BVD control in New Zealand...

BACKGROUND: Earlier diagnosis of HIV infection improves health outcomes and reduces transmission. In New Zealand half of new HIV diagnoses between 2005 and 2010 had a CD4 count below 350 cells/mm3 . HIV screening is already offered in antenatal settings in New Zealand, but not universally in hospital settings. AIMS: To assess the impact of missed opportunities to diagnose HIV infection in adults presenting to hospital services at Auckland District Health Board (ADHB)...

Nipah virus (NiV) encephalitis first reported in "Sungai Nipah" in Malaysia in 1999 has emerged as a global public health threat in the Southeast Asia region. From 1998 to 2018, more than 630 cases of NiV human infections were reported. NiV is transmitted by zoonotic (from bats to humans, or from bats to pigs, and then to humans) as well as human-to-human routes. Deforestation and urbanization of some areas have contributed to greater overlap between human and bat habitats resulting in NiV outbreaks...

Human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a rare chronic neuroinflammatory disease. While the disease usually progresses slowly without remission, there is a subgroup of patients with rapid progression and another subgroup with very slow progression. However, there have been no reports to date that have successfully determined the criteria to differentiate these subgroups. Therefore, we initially conducted a statistical modeling analysis to explore representative patterns of disease progression using data from our nationwide HAM/TSP patient registration system ("HAM-net")...

The Latin American 2015-2016 Zika virus (ZIKV) outbreak was associated with an increase in microcephaly predominantly in northeastern Brazil. To comparatively investigate infectious causes of congenital malformations, we performed a nested case-control study in 32 mothers of cases of suspected congenital Zika syndrome (CZS) and 160 age-matched controls from Bahia, northeastern Brazil. We collected clinical and imaging data and assessed past exposure to ZIKV, Chikungunya virus (CHIKV), dengue virus, and 8 established TORCH ( Toxoplasma gondii , Treponema pallidum , rubella virus, cytomegalovirus, herpes simplex virus 1 [HSV-1] and HSV-2, varicella-zoster virus, parvovirus B19) pathogens using multiple serological tests...

Background: Due to the success of antiretroviral therapy, human immunodeficiency virus (HIV) infection has been transformed into a lifelong condition. In Italy, little is known about the impact of comorbidities (CMs) on the risk of hospitalization and related costs for people who live with HIV (PWLHIV). The objective of the study was to quantify the risk of hospitalization and costs associated with CMs in an Italian cohort of PWLHIV. Methods: The study population included subjects aged ≥18 years with HIV infection, identified in the Abruzzo's hospital discharge database among files stored from 2004 until 2013 and then followed up until December 2015...

BACKGROUND Pneumocystis jiroveci pneumonia (PCP) - formerly known as Pneumocyctis carinii pneumonia - with newly diagnosed AIDS is an uncommon presentation in people over 50 years of age. A high level of suspicion is required for this diagnosis when an elderly patient with pneumonia is not responding to broad-spectrum antibiotic treatment. CASE REPORT We describe the case of a 63-year-old woman who presented with dyspnea, cough, and significant hypoxemia requiring high-flow oxygen supplement with bilateral lung infiltrates, treated with broad-spectrum antibiotics for a presumed diagnosis of pneumonia...

A label-free light-up fluorescent sensing strategy using hybridization chain reaction (HCR) amplification and DNA triplex assembly has been developed. Remarkably, the proposed fluorescence assay is successfully applied to the determination of avian influenza A (H7N9) virus DNA and thrombin. Herein, in the presence of targets, the target DNA/initiator triggers a cascade of hybridization events between H1 and H2 that yields nicked double helices analogous to alternating copolymers. With the additions of triplex-forming oligonucleotide (TFO) and berberine, the triplex structures form between HCR products and TFO...
