在疫苗广泛使用之前,早期检测和有效控制传播途径仍然是应对 COVID-19 大流行的最有效方法。 香港科技大学霍英东研究院博士后宋祺,上海大学的博士研究生孙新迪为该项研究工作“Point-of-Care Testing Detection Methods for COVID-19”的共同第一作者。香港科技大...
Covid-19 has posed challenges to medical sciences concerning the methods and the process of testing. Manyimmunoassays, serological and molecular testswere rapidly developed, each of them having a different degree of specificityand based on different target molecules from SARS-CoV-2 or the body in ...
In the recent SARS-CoV-2 pandemic, public health experts have emphasized testing, tracking infected people, and tracing their contacts as an effective strategy to reduce the spread of the virus. Several diagnostic methods are reported for detecting the coronavirus in clinical, research, and public ...
Some conventional methods were improved and commercialized, such as antibody and antigen testing kits for point-of-care use [13], developed methods of SARS-CoV-2 RNA detection, such as RT-LAMP (Reverse Transcription Loop-Mediated Isothermal Amplification) and Cas-Crispr, and testing for virus in...
For COVID-19, it is vital to understand if quarantines shorter than 14 days can be equally effective with judiciously deployed testing. Here, we develop a mathematical model that quantifies the probability of post-quarantine transmission incorporating testing into travel quarantine, quarantine of tra...
It's important to follow the recommended procedures for sample collection to ensure accurate and reliable test results. Additionally, advancements in testing methods and materials may lead to variations in swab types and collection techniques over time. Always refer to the latest guidelines from health...
Finally, in the testing phase, the trained model is evaluated. Along with fine-tuning on the top layers of the CNN, VGG16, VGG19, DenseNet201, Inception_ResNet_V2, Inception_V3, Xception, Resnet50, and MobileNet_V2 architectures, a comparative study is conducted [52]. Three convolutional...
However, antibody testing cannot replace nucleic acid testing, Feng said, adding that antibody testing can provide an auxiliary diagnosis for those negative cases detected by nucleic acid testing. More detection kits and methods are on their way to be put into use as China continues to make progr...
Since trial participants may not be able to come to the investigational site for protocol- specified visits, sponsors should evaluate whether alternative methods for safety assessments (e.g., phone contact, virtual visit, alternative location for assessment, including local labs or imaging centers) co...
The fourth section analyze the proposed method and presents the experimental results on COVID-19. The fifth section discusses the proposed method and analyzes the final medical data results. 2. Materials and methods 2.1. Data collection Our study was approved by the Ethics Committee of the ...
