How Scientists Are Using AI and Data Science Against COVID-19

In a new study in China, a deep learning model detected COVID19 caused pneumonia from CT scans with comparable performance to expert radiologists. CT is the preferred imaging method for evaluating lung infection, assessing progression, and determining treatment options for patients with pneumonia caused by COVID19. In this study, radiologists used AI to help them evaluate the progression of disease, and with the assistance of this model, radiologists' read time decreased by 65%. The model achieved a per-patient sensitivity of 100% and accuracy of 95.24%. This AI could help improve the efficiency of evaluation and diagnosis especially if the number of people with the virus increases. This article is a preprint and has not been peer-reviewed. This paper reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice. Harvard Medical School students have created a COVID19 curriculum. It includes information about epidemiology, clinical management, testing, treatment, vaccine development, and communication. Each section was reviewed by at least two Harvard Medical School faculty experts. Many modules reference supplemental resources that may be worth accessing in the future and to find the most current statistics of the pandemic. Also included are one-page summaries of each module's key takeaways. COVID19 testing in South Korea is free and convenient and over 250,000 people have already been tested. The South Korean data is valuable because they are testing people who have symptoms and people who have no symptoms. This is unusual because most countries are only testing people who are sick to confirm that they have the virus. South Korea is testing everyone, including asymptomatic people, as a public health measure so that anyone who has the virus can isolate even if they don't feel sick. In most countries asymptomatic people are not tested for COVID19. For example Italy is only testing symptomatic people, whereas South Korea tests everyone and picks up more mild cases.
