Middle East respiratory syndrome coronavirus (MERS-CoV) – Saudi...
Thu, 02 Jul 2020Between 1 April and 31 May 2020, the National IHR Focal Point of Saudi Arabia reported nine new cases of MERS-CoV infection, including five deaths. The cases were reported from Riyadh (seven cases), Assir (one case) and Northern (one case) Regions. Most cases were and ages of the reported cases ranged from 40 to 96 years.
Of the cases reported in Riyadh six were from a hospital outbreak in the region between 21 and 31 May 2020: an index case who was a newly admitted patient, and five secondary cases identified through contact tracing. One of the secondary cases was a health care worker and the other four were in-patients admitted due to other health conditions. All four in-patients were bedridden and above 75 years of age. All reported cases had comorbidities with the exception of the healthcare worker.
Ebola virus disease – Democratic Republic of the Congo ...
Fri, 26 Jun 2020On 25 June 2020, the Minister of Health of the Democratic Republic of the Congo declared the end of the Ebola Virus Disease (EVD) outbreak in North Kivu, Ituri and South Kivu Provinces . In accordance with WHO recommendations, the declaration was made more than 42 days after the last person who contracted EVD in this outbreak tested negative twice and was discharged from care.
The outbreak was declared on 1 August 2018 following investigations and laboratory confirmation of a cluster of EVD cases in North Kivu Province. Further investigations identified cases in Ituri and North Kivu Provinces with dates of symptom onset from May to August 2018. In 2019, the outbreak subsequently spread to South Kivu Province, and on 17 July 2019, the WHO Director-General declared the outbreak a Public Health Emergency of International Concern. In the Democratic Republic of the Congo, 11 outbreaks have been recorded since the first recognized outbreak in 1976. The 10th EVD outbreak in North Kivu, Ituri and South Kivu Provinces was the country's longest EVD outbreak and the second largest in the world after the 2014–2016 EVD outbreak in West Africa.
Ebola virus disease – Democratic Republic of the Congo ...
Thu, 18 Jun 2020No new confirmed cases of Ebola virus disease (EVD) have been reported in Ituri, North Kivu and South Kivu Provinces of the Democratic Republic of the Congo since 27 April 2020 (Figure 1). While this is a positive development, there remains a risk of re-emergence of EVD. It is critical to maintain surveillance and response operations in the period leading up to the declaration of the end of the outbreak, as well as after the declaration – as outlined in the WHO recommended criteria for declaring the end of the EVD outbreak .
From 11 to 16 June 2020, an average of 2939 alerts were reported per day, of which 2788 (about 95%) were investigated within 24 hours. Of these, an average of 453 alerts were validated as suspected cases each day, requiring specialized care and laboratory testing to rule-out EVD. The number of reported and validated alerts has remained stable in recent weeks. Timely testing of suspected cases continues to be provided from eight laboratories. From 8 to 14 June 2020, 3219 samples were tested including 2513 blood samples from alive, suspected cases; 324 swabs from community deaths; and 382 samples from re-tested patients. Overall, the number of samples tested by the laboratories increased by 3% compared to the previous week.

Evidence Review for Centers for Disease Control and Prevention Gu...
Wed, 24 Jun 2020AbstractThe articles in this supplement address key questions on syphilis diagnostics, provide reference tables of test performances, and discuss optimal specimens and knowledge gaps. Laboratory-developed genetic direct detection tests could be most useful at the point of care and add to the currently available serologic methods of nontreponemal and treponemal tests.
Sensitivity and Specificity of Treponemal-specific Tests for the ...
Wed, 24 Jun 2020AbstractWe conducted a systematic review of relevant syphilis diagnostic literature to address the question, “What is the sensitivity and specificity of the treponemal tests currently approved by the Food and Drug Administration (FDA) for the diagnosis of syphilis (by stage)?” There were 16 treponemal assays evaluated: 13 immunoassays and 3 manual assays (fluorescent treponemal antibody absorbed test [FTA-ABS], microhemagglutination assay for Treponema pallidum antibodies [MHA-TP], Treponema pallidum particle agglutination assay [TP-PA]). MHA-TP and FTA-ABS were less sensitive in primary and secondary syphilis than TP-PA; TP-PA is the most specific manual treponemal assay. There is insufficient evidence to recommend one particular treponemal immunoassay (eg, enzyme immunoassays, chemiluminescence immunoassays, microbead immunoassays) over another based on published performance data. For diagnosis of neurosyphilis, cerebrospinal fluid (CSF) TP-PA has similar performance to CSF FTA-ABS in studies with patients with definitive or presumptive neurosyphilis. However, CSF treponemal testing has limitations in its sensitivity and specificity and should be interpreted within the context of the clinical scenario, additional CSF test results and syphilis prevalence.
Molecular and Direct Detection Tests for Treponema pallidum Subsp...
Wed, 24 Jun 2020AbstractDirect detection methods for Treponema pallidum include dark-field microscopy (DFM), direct fluorescence antibody (DFA) testing, immunohistochemistry (IHC), and nucleic acid amplification tests (NAATs). Here, we reviewed the relevant syphilis diagnostic literature to address 2 main questions with respect to T. pallidum direct detection techniques: “What are the performance characteristics for each direct detection test for T. pallidum and what are the optimal specimen types for each test?” and “What options are available for T. pallidum molecular epidemiology?” To answer these questions, we searched 5 electronic databases (OVID Medline, OVID Embase, CINAHL, Cochrane Library, and Scopus) from 1964 to 2017 using relevant search terms and identified 1928 articles, of which 37 met our inclusion criteria. DFM and DFA sensitivities ranged from 73% to 100% in cases of primary syphilis; and while sensitivity using silver stain histopathology for T. pallidum was generally low (0%–41%), higher performance characteristics were observed for T. pallidum–specific IHC (49–92%). Different genes have been targeted by T. pallidum–specific NAATs, with the majority of studies indicating that sensitivity is primarily dependent on the type of collected biological sample, with highest sensitivity observed in primary lesion exudate (75–95%). Given the rising incidence of syphilis, the development of direct, Food and Drug Administration–cleared T. pallidum NAATs should be considered an immediate priority.

Wed, 20 Dec 2017
The “mutational burden,” or the number of mutations present in a tumor’s DNA, is a good predictor of whether that cancer type will respond to a class of cancer immunotherapy drugs known as checkpoint inhibitors, a new study led by
Johns Hopkins Kimmel Cancer Centerresearchers shows. The finding, published in the Dec. 21 New England Journal of Medicine, could be used to guide future clinical trials for these drugs.

Mon, 18 Dec 2017
In a study using genetically engineered mice, Johns Hopkins researchers have uncovered some new molecular details that appear to explain how electroconvulsive therapy (ECT) rapidly relieves severe depression in mammals, presumably including people. The molecular changes allow more communication between neurons in a specific part of the brain also known to respond to antidepressant drugs.

2020-07-08Quick identification and isolation of patients with highly infectious diseases is extremely important in healthcare settings today. This study focused on the creation of a digital screening tool using a free and publicly available digital survey application to screen patients during a measles outbreak in New York City. The results indicate that digital tools are an effective alternative to paper tools due to their ease of use and remote compliance monitoring capabilities.

2020-07-08A cluster of cases of pneumonia of unknown etiology in Wuhan, China were reported to the World Health Organization on December 31, 2019. Subsequently, the causative agent was identified as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the associated disease was named COVID-19. By June 19, 2020, 117,472 deaths in the United States were attributed to COVID-19.(1)
