More thanpeople have recovered. The virus is primarily spread between people during close contact, [a] often via small droplets produced by coughing, [b] sneezing, or talking. The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction rRT-PCR from a nasopharyngeal swab. Recommended measures to prevent infection include frequent hand washingmaintaining physical distance from others especially from those with symptomscovering coughs and sneezes with a tissue or inner elbow, and keeping unwashed hands away from the face.
Those infected with the virus may be asymptomatic or develop flu-like symptoms such as fever, cough, fatigue, and shortness of breath. Gastrointestinal symptoms such as nauseavomiting and diarrhoea have been observed in varying percentages. Coronavirii can also pass into the braincausing neurological symptoms, but little research has been done on this.
Neurological symptoms of the disease may include headachesdizzinessanosmia loss of smell and tastemuscle pain and fatigue. As is common with infections, there is a delay between the moment when a person is infected with the virus and the time when they develop symptoms. This is called the incubation period. Reports indicate that not all who are infected develop symptoms. The role of these asymptomatic carriers in transmission is not yet fully known;  however, preliminary evidence suggests that they may contribute to the spread of the disease.
Some details about how the disease is spread are still being determined. Respiratory droplets may also be produced while breathing out, including when talking. Though the virus is not generally airborne  the National Academy of Science has suggested that bioaerosol transmission may be possible and air collectors positioned in the hallway outside of people's rooms yielded samples positive for viral RNA. It may also spread when one touches a contaminated surface, known as fomite transmission, and then touches one's eyes, nose or mouth.
The virus is most contagious when people are symptomatic; while spread may be possible before symptoms emerge, the risk is low.
The virus survives for hours to days on surfaces. Soap and detergent are also effective if correctly used; soap products degrade the virus' fatty protective layer, deactivating it, as well as freeing them from skin and other surfaces. In a Hong Kong study, saliva samples were taken a median of two days after the start of hospitalization.
In five of six patients, the first sample showed the highest viral load, and the sixth patient showed the highest viral load on the second day tested. Genetic analysis has revealed that the coronavirus genetically clusters with the genus Betacoronavirusin subgenus Sarbecovirus lineage B together with two bat-derived strains.
The lungs are the organs most affected by COVID because the virus accesses host cells via the enzyme angiotensin-converting enzyme 2 ACE2which is most abundant in the type II alveolar cells of the lungs.
The virus uses a special surface glycoprotein called a "spike" peplomer to connect to ACE2 and enter the host cell. The virus also affects gastrointestinal organs as ACE2 is abundantly expressed in the glandular cells of gastricduodenal and rectal epithelium  as well as endothelial cells and enterocytes of the small intestine. The virus can cause acute myocardial injury and chronic damage to the cardiovascular system.
Systemic inflammation results in vasodilation, allowing inflammatory lymphocytic and monocytic infiltration of the lung and the heart. The WHO has published several testing protocols for the disease.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Supporting Information.If you need to build a desktop application today, Electron is an increasingly common choice.
It is cross-platform and is built using the same web technologies that you probably already know. First we need a vanilla Electron project. It will be virtually identical to the official Electron First App tutorial and the Electron Quickstart repository. Electron has two separate processes: a main process, which is Electron itself, and a render process, which is essentially a web page that Electron loads in a Chromium-based browser.
We just need to install the TypeScript compiler and configure it. Webpack configuration consists of an array of entry points. Webpack processes each entry point by passing the file and its dependencies through a loader.
Loaders are selected via rulesoften with a loader per file extension. Finally, Webpack dumps the output to a specified location. Our render entry point is.
Webpack will process our entry point and its dependencies and load the result into our index. With our output files now inside the dist directory, we need to update our npm scripts to match. As it turns out, Electron is well suited for running the major front-end frameworks and Webpack is well suited for packaging multiple things at once. The whole process just needed a little demystification.

Install dependencies npm install --save-dev typescript TypeScript configuration touch tsconfig. Specifies any plugins used during the build process. Plugins differ from loaders in that plugins operate at the bundle level and can more deeply integrate with the build process via hooks. Loaders operate at the file level.

Latest commit a Sep 10, A basic Electron application needs just these files: package.If you don't currently have a Windows installation, dev. Building Electron is done entirely with command-line scripts and cannot be done with Visual Studio.
You can develop Electron with any editor but support for building with Visual Studio will come in the future. Note: Even though Visual Studio is not used for building, it's still required because we need the build toolchains it provides. You can build the 32bit target alongside the 64bit target by using a different output directory for GN, e. If you encountered an error like Command xxxx not foundyou may try to use the VS Command Prompt console to execute the build scripts.
Creating that directory should fix the problem :. This should fix it:. This bug is a "feature" of Windows' command prompt. It happens when clicking inside the prompt window with QuickEdit enabled and is intended to allow selecting and copying output text easily. Since each accidental click will pause the build process, you might want to disable this feature in the command prompt properties. Choose Your Site Language. Wikang Tagalog Tagalog. Italiano Italian.

Keyboard Shortcuts.Having no prior experience in developing Electron App, I sat down to do some research.
The documentation mentions React support with both the processes through Electron-Forge CLI or electron-react-boilerplate. Electron-Forge is similar to create-react-app CRA in terms of scaffolding the base solution and getting a ready-to-run application setup correctly. Having had an excellent experience with CRA before, I chose to start my project using electron-forge.
Although Electron docs mentions electron-forge has ready to use templates for React, at the time of writing electron-forge documentation does not list any React template nor any guide on how to setup React or TypeScript. Moreover there was surprisingly little information available on the web regarding this. Babel is a great package in itself and I would recommend everyone to go through this excellent article on how Babel and TypeScript works together.
This increases compile speed dramatically one major complain from TypeScript at the cost forgoing type checking at build time. There are workarounds like type-checking during test that are described in more details in the article above and I would recommend everyone to read it. You may or may not like this approach depending upon your project and team configuration.
There are two ways to setup electron-forge - vanilla installation or using a template. We will setup using Webpack template the only available template at the time of writing. We use ts-loader as loader for webpack and fork-ts-checker-webpack-plugin for faster builds. Since we are not using Babel, we will need to create config file for TypeScript. Create a tsconfig. Now run the application using yarn start and React should render correctly.
We only setup TypeScript in renderer as that is most likely place where usually development happens. However if you want to use TypeScript for developing main process you will need to make some additional changes.
We have only changed 3 lines of code. First is to replace require statement with import statement. The last step is to fix build error by explicitly setting type of variable mainWindow to any. This is because of missing extensions configuration in webpack. In both webpack. F5 A simple blog regarding ASP. NET, Azure, Angular and other random stuffs.
