Classification of COVID-19 patients from chest CT images using multi-objective differential evolution-based convolutional neural networks.
Early classification of 2019 novel coronavirus disease (COVID-19) is essential for disease cure and control. Compared with reverse-transcription polymerase chain reaction (RT-PCR), chest computed tomography (CT) imaging may be a significantly more trustworthy, useful, and rapid technique to classify and evaluate COVID-19, specifically in the epidemic region. Almost all hospitals have CT imaging machines; therefore, the chest CT images can be utilized for early classification of COVID-19 patients. ⋯ Additionally, the initial parameters of CNN are tuned using multi-objective differential evolution (MODE). Extensive experiments are performed by considering the proposed and the competitive machine learning techniques on the chest CT images. Extensive analysis shows that the proposed model can classify the chest CT images at a good accuracy rate.

The role of community-wide wearing of face mask for control of coronavirus disease 2019 (COVID-19) epidemic due to SARS-CoV-2.
Face mask usage by the healthy population in the community to reduce risk of transmission of respiratory viruses remains controversial. We assessed the effect of community-wide mask usage to control coronavirus disease 2019 (COVID-19) in Hong Kong Special Administrative Region (HKSAR). ⋯ Community-wide mask wearing may contribute to the control of COVID-19 by reducing the amount of emission of infected saliva and respiratory droplets from individuals with subclinical or mild COVID-19.

Tocilizumab was approved for chimeric antigen receptor T-cell therapy induced cytokine release syndrome and it may provide clinical benefit for selected COVID-19 patients. ⋯ In patients with severe COVID-19, tocilizumab was associated with significantly shorter duration of vasopressor support. Although not statistically significant, tocilizumab also resulted in shorter median time to clinical improvement and shorter duration of invasive ventilation. These findings require validation from ongoing clinical trials of Tocilizumab in COVID-19 patients.

The novel coronavirus, COVID-19, proliferates as a contagious psychological threat just like the physical disease itself. Due to the growing death toll and constant coverage this pandemic gets, it is likely to activate mortality awareness, to greater or lesser extents, depending on a variety of situational factors. ⋯ We provide predictions and recommendations for shifting reactions to this pandemic towards behaviours that decrease, rather than increase, the spread of the virus. We conclude by considering the benefits of shifting towards collective mindsets to more effectively combat COVID-19 and to better prepare for the next inevitable pandemic.
