COVID-19 Threat to the World: Current and Possible Diagnostic/Treatment Strategies

Abstract: The outbreak of coronavirus disease 2019 has resulted in a world-wide crisis. To contain the virus, it is important to find infected individuals and isolate them to stop transmission. Various diagnostic techniques are used to check for infection. With the havoc that severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has created, it is imperative to work on alternative diagnostic techniques that can be used at both point of care with little or no expertise and at mass testing (i.e., when screening). … Show more

“…It was observed that the blue/green ratio of the three RAPPID sensors increased with increasing concentrations of the three ADAs anti-antibodies (Figure e). COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has an negative impact for public health, making SARS-CoV-2 antigen and antibody testing critical. By combining 47D11, D001, and D003, three immunogenic receptor-binding domains (RBDs) of SARS-CoV-2 linked to the SB or LB of the RAPPID sensor. The blue/green ratios of all three RAPPID sensors response curves increased with increasing antibody concentration.…”

“…In the first months after the pandemic outbreak, especially in the first half of 2020, therapeutic schemes launched by infectionists [4][5][6][7][8][9], defined as being the most suitable for the moment, varied a lot. Of all the immunomodulatory drugs, only tocilizumab was available for 2-3 months towards the end of 2020, and only in intensive care units; otherwise, dexamethasone was widely used.…”

“…Testing during outbreaks remains the most reliable tool for directing efforts and resources; it is the identification of infected individuals that can help to mitigate transmission. 1 The variety of test modalities available (including PCR, LAMP, antigen, and serology tests; Supplementary Table 1) can be used to support outbreak-response efforts in three key ways: (1) diagnostic testing for symptomatic individuals, (2) diagnostic testing for asymptomatic individuals, and (3) large-scale screening for ongoing disease surveillance.…”
