Task
The World Health Organization has declared the outbreak of the novel coronavirus, Covid-19 as pandemic across the world. With its alarming surge of affected cases throughout the world, lockdown, and awareness (social distancing, use of masks etc.) among people are found to be the only means for restricting the community transmission. In a densely populated country like India, it is very difficult to prevent the community transmission even during lockdown without social awareness and precautionary measures taken by the people. This app mainly focuses on development of an Android application which can inform people of their probability of contraction. This Android application sends a unique code to another phone which has installed the same app via bluetooth.The app uploads the details of their contact into the Neo4j database. The application also notifies the users if they have come in contact with a covid positive patient.The app also gives details of the hotspots surrounding a person based on their location. To achieve all these functionalities, many tools, and APIs like beacon,Neo4j are used in this application. Therefore, this application can be used as a tool for creating further social awareness about the arising need of precautionary measures to be taken by the people of India.
Currently there are several research works undergoing in the country to prevent Covid-19 cases from rising. Previously our country was importing medical kits like PPE (Personal Protection Kits), mask from outside, but now it has been successful in developing these kits. Along with taking initiatives to fight this disease, our country has also taken steps to make people aware of the disease. The news and media have a great part in creating this awareness by informing the public about the preventive measures that can keep them away from infection. Awareness among the people to carry out all the preventive measures can immensely help to reduce spread of the virus. The country has created containment zones throughout the cities wherever Covid-19 cases have been reported to prevent further spread of the virus. These containment zones have been kept isolated from the outside public to ensure no contamination occurs outside. After more than 2 months of the lockdown, the government has relaxed some of the lockdown rules and has permitted reopening of government offices, bus and other road transportation facilities and shopping markets. People can move inside the city for work and other purposes. But people have become careless leading to more infected cases.Once a person comes in contact with another infected person it leads to cycle of new cases.Therefore, informing people about their probability of contraction can enable them to test themselves and thereby reduce the chance of community transmission
1.1 Existing Apps in Google Playstore Related to Covid-19
We had conducted a brief survey on the existing apps published in Google playstore which are related to Covid-19. Efforts had been made to include most of the apps in the survey. The summary of the survey told us that the current crop of apps couldn’t solve our problem what we are looking for is an efficient and easy way to find the contacts of a covid positive patient and alert them of their probability of contarction.
1.2 Project Outline
A unique user id is interchanged between two users with the same app when they come in proximity of the same bluetooth network.The bluetooth signal is broadcasted by a flutter package called beacon.While establishing the contact we retreive the humidity,temperature,contact duration and the location details of the place and send the data to the Neo4j database.The data gets stored in the Neo4j Graph Database where it is used to find out the contacts of a covid positive patient.When a person is tested positive his contacts are retrieved and their data is processed and the corresponding probability of contraction is obtained and is sent back to the
users.
