Colloidal Gold Immunochromatographic Strip

The outbreak of the new coronavirus (SARS-CoV-2) infection has become a global public health crisis. Antigen detection strips (colloidal gold) can be widely used in novel coronavirus clinical screening and can even be extended to home self-testing, which provides a practical and effective way for people to obtain health status information away from the crowd. In this paper, a colloidal gold detection system without complex devices is proposed, which is based on smartphone usage along with a mobile-phone software embedded with normalization algorithms and a special designed background paper. The basic principle of the device relies on image processing. First, the data of the green channel of the image captured by a smartphone are selected to be processed. Second, the calibration curves are established using standard black and white card, and the calibration values under different detection environments are obtained by calibration curves. Finally, to verify the validity of the proposed method, various standard solutions with different concentrations are tested. Results show that this method can eliminate the influence of different environments on the test results, the test results in different detection environments have good stability and the variation coefficients are less than 5%. It fully proves that the detection system designed in this paper can detect the result of colloidal gold immunochromatographic strip in time, conveniently and accurately in different environments.

Pandemic of novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infections in China is now become global public health crisis. At present 87.64% of the world is infected by this deadly illness. The risk from this epidemic depends on the nature of the virus, including how well it transmits from person to person, and the complications resulting from this current illness. The novel coronavirus has killed thousands of people in China and other countries as well; its rate of mortality is increasing day by day. There is an urgent need to control the virus by developing vaccine or any other antiviral drugs to save the world from this deadly viral infection.

The spread of the novel coronavirus (SARS-CoV-2) has resulted in the most devastating global public health crisis in over a century. At present, over 10 million people from around the world have contracted the Coronavirus Disease 2019 (COVID-19), leading to more than 500,000 deaths globally. The global health crisis unleashed by the COVID-19 pandemic has been compounded by political, economic, and social crises that have exacerbated existing inequalities and disproportionately affected the most vulnerable segments of society. The global pandemic has had profoundly geographical consequences, and as the current crisis continues to unfold, there is a pressing need for geographers and other scholars to critically examine its fallout. This introductory article provides an overview of the current special issue on the geographies of the COVID-19 pandemic, which includes 42 commentaries written by contributors from across the globe. Collectively, the contributions in this special issue highlight the diverse theoretical perspectives, methodological approaches, and thematic foci that geographical scholarship can offer to better understand the uneven geographies of the Coronavirus/COVID-19.

Background: Since December 2019, many patients with novel coronavirus pneumonia (NCP) have appeared in Wuhan, Hubei Province, China. The pneumonia was caused by a novel coronavirus named “coronavirus disease 2019, COVID-19” by the WHO on February 11, 2020. The COVID-19 outbreak has created a global public health crisis, and the challenge of combatting this pandemic and its impact is daunting. At present, vaccines and prophylactic therapies for COVID-19 are not available. What we can do now is to aggressively implement infection control measures to prevent the spread of COVID-19 via human-to-human transmission. Objectives: The study aimed to summarize the effect of classification and division management methods on the prevention and control of COVID-19 in the Pediatric Immunology and Rheumatology Department. Methods: Corresponding and targeted medical countermeasures for the prevention and control of COVID-19 from the aspects of personnel, ward, and process management were retrospectively analyzed. Results: From January 16, 2020, to July 31, 2020, there were 11,000 outpatients with rheumatic disease visiting our hospital and 565 children with rheumatic diseases hospitalized in our department. All the patients received timely and reasonable treatment. None of the patients, their caregivers, or medical staff acquired COVID-19 infection in our department, and no suspected COVID-19 case was confirmed in our ward. Conclusions: The model of classification and division management ensured the orderly and safe treatment of children with rheumatic disease during the epidemic prevention and control period, and protected the medical staff from occupational injuries at work, and brought the pandemic under control.
