Our team and I work on a project for the Lauzhack 2020 and to achieve this work, we need to determine some factors that can tell us what is the probability of contracting the coronavirus. Is there any one who know what are the determining factor to compute the probability of catching the virus ? (for example some research paper about it). For example, we know that if we are old, and if we are in contact regularly with people, we are most likely to catch the disease. We would like to have some basic knowledge about the transmission of the virus. We would need data about the probability of being infected as a function of the time we had been in contact with someone who have the disease. Any help would be appreciated !
