Symptoms at disease onset predict prognosis in COVID-19 disease
The main clinical manifestations of coronavirus disease 2019 (COVID-19) onset are respiratory symptoms, including cough, sputum, and dyspnea. However, a significant proportion of patients initially manifested non-respiratory symptoms, such as fever, myalgia, and diarrhea. Respiratory patients had more secondary bacterial infections, needed the intensive care unit more (9.7% vs 2.2%, P =0.005), developed ARDS more (11.4%) and needed longer time to recover (18.5 vs 16.7 days)

A biological sub-sequences detection using integrated BA-PSO based on infection propagation mechanism: Case study COVID-19
The longest common consecutive subsequences (LCCS) play a vital role in revealing the biological relationships between DNA/RNA sequences especially the newly discovered ones such as COVID-19. FLAT is a Fragmented local aligner technique which is an accelerated version of the local pairwise sequence alignment algorithm based on meta-heuristic algorithms. This paper introduces a modified version of FLAT based on improving the performance of the BA algorithm by integration with particle swarm optimization (PSO) algorithm. It has a preponderance to find the LCCS with the highest percentage (88%) which is better than other state-of-the-art methods.

Big data directed acyclic graph model for real-time COVID-19 twitter stream detection
" The aim of this work is to detect anomalous events associated with COVID-19 from Twitter. We obtained the three most commonly listed terms on Twitter: ""covid"", ""death"", and ""Trump"" (21,566, 11,779, and 4761 occurrences) On 18 August 2020, our model detected the highest anomaly since many tweets mentioned the casualties' updates and debates on the pandemic that day. These terms were located near each other on vector space so that they were clustered, indicating people's most concerned topics on Twitter."

Behavior of cough droplets emitted from Covid-19 patient in hospital isolation room with different ventilation configurations
The ventilation system in hospital isolation rooms with infectious patients plays a significant role in minimizing the spread of viruses and the risk of infection in hospital. We found that the evaporation rate of droplets is strongly dependent on the relative humidity (RH) and, at low RH, the large-sized droplets with Covid-19 virus can evaporate quickly and become small-sized aerosols to stay in air for a long time.

Towards an efficient collection and transport of COVID-19 diagnostic specimens using genetic-based algorithms
The Tunisian ministry of health established a protocol planning the sample collection from the patients at their location. A triage score is first assigned to each patient according to the symptoms he is showing, and his health conditions. Then, given the limited number of the available ambulances in each area, the location of the patients and the capacity of the nearby hospitals for receiving the samples, an ambulance scheduling and routing plan needs to be established so that specimens can be transferred to hospitals in short time.

The behavioral immune system and vaccination intentions during the coronavirus pandemic
The behavioral immune system is considered to be a psychological adaptation that decreases the risk of infection. Research suggests that, in the current environment, this system can produce attitudes with negative health consequences. Those with higher germ aversion during the pandemic perceived vaccines to be safer and had higher intentions to accept vaccination.

Linking the behavioral immune system to COVID-19 vaccination intention: The mediating role of the need for cognitive closure and vaccine hesitancy
Study finds that perceived vulnerability to disease (PVD) is associated with vaccination intentions through the need for cognitive closure (NCC) and vaccine hesitancy. Perceived infectability, on the other hand, is directly related to vaccination intention. We discuss the potential benefits of considering the roles of BIS and NCC in campaigns and policies aimed at increasing COVID-19 vaccine uptake.

Monitoring populations at increased risk for SARS-CoV-2 infection in the community using population-level demographic and behavioural surveillance
Real-time population screening and identification of groups in whom positivity is highest could help monitor spread and inform public health messaging and strategy. Of 4,091,537 RT-PCR results from 482,677 individuals, 29,903 (073%) were positive. As positivity rose September-November 2020, rates were independently higher in Northern England, major urban conurbations, more deprived areas, and larger households. Rates were also higher in those returning from abroad, and working in healthcare or outside of home.
