Recently, the coronavirus disease 2019 (COVID-19) has caused a pandemic in over 200 countries, influencing billions of humans. To control infection, identifying and separating infected people is most crucial step. The main diagnostic tool Reverse Transcription Polymerase Chain Reaction (RT-PCR) test. Still, sensitivity RT-PCR test not high enough to effectively prevent pandemic. chest CT scan provides valuable complementary test, it can identify patients early-stage with sensitivity. However, usually time-consuming, requiring about 21.5 minutes per case. This paper develops novel Joint Classification Segmentation (JCS) system perform real-time explainable COVID-19 diagnosis. train our JCS system, we construct large scale (COVID-CS) dataset, 144,167 images 400 350 uninfected cases. 3,855 are annotated fine-grained pixel-level labels opacifications, which increased attenuation lung parenchyma. We also have lesion counts, opacification areas, locations thus benefit various diagnosis aspects. Extensive experiments demonstrate that proposed very efficient for classification segmentation. It obtains an average 95.0% specificity 93.0% on set, 78.5% Dice score segmentation set COVID-CS dataset. dataset code available at https://github.com/yuhuan-wu/JCS.

In recent decades, several new diseases have emerged in different geographical areas, with pathogens including Ebola virus, Zika Nipah and coronaviruses (CoVs). Recently, a type of viral infection Wuhan City, China, initial genomic sequencing data this virus do not match previously sequenced CoVs, suggesting novel CoV strain (2019-nCoV), which has now been termed severe acute respiratory syndrome CoV-2 (SARS-CoV-2). Although coronavirus disease 2019 (COVID-19) is suspected to originate from an animal host (zoonotic origin) followed by human-to-human transmission, the possibility other routes should be ruled out.

An ongoing theme of the COVID-19 pandemic is need for widespread availability accurate and efficient diagnostic testing detection SARS-CoV-2 antiviral antibodies in infected individuals. This report describes various assay techniques tests diagnosis. Most early RNA rely on reverse transcription-polymerase chain reaction, but isothermal nucleic acid amplification assays, including transcription-mediated CRISPR-based methodologies, are promising alternatives. Identification individuals who have developed to virus requires serological tests, enzyme-linked immunosorbent (ELISA) lateral flow immunoassay. also provides an overview current development products facilitate future improvement innovation.

The current outbreak of the pandemic coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) demands its rapid, convenient, and large-scale diagnosis to downregulate spread within as well across communities. But reliability, reproducibility, selectivity majority such diagnostic tests fail when they are tested either a viral load at early representation or gene mutated during spread. In this regard, selective "naked-eye" detection SARS-CoV-2 is highly desirable, which can be without accessing any advanced instrumental techniques. We herein report development colorimetric assay based on gold nanoparticles (AuNPs), capped with suitably designed thiol-modified antisense oligonucleotides (ASOs) specific for N-gene (nucleocapsid phosphoprotein) SARS-CoV-2, could used diagnosing positive COVID-19 cases 10 min from isolated RNA samples.

The current COVID-19 pandemic presents a serious public health crisis, and better understanding of the scope spread virus would be aided by more widespread testing. Nucleic-acid-based tests currently offer most sensitive early detection COVID-19. However, “gold standard” test pioneered U.S. Centers for Disease Control Prevention takes several hours to complete requires extensive human labor, materials such as RNA extraction kits that could become in short supply, relatively scarce qPCR machines. It is clear huge effort needs made scale up testing orders magnitude. There thus pressing need evaluate alternative protocols, reagents, approaches allow nucleic-acid continue face these potential shortages. has been tremendous explosion number papers written within first weeks evaluating advances, comparable alternatives “gold-standard” CDC RT-PCR test. Here we present collection recent advances nucleic acid testing, including both peer-reviewed preprint articles. Due rapid developments during this have included many publications possible, but cited sources not yet peer-reviewed, so urge researchers further validate results their own laboratories.
