DarkCovidNet, a deep learning model is used with 17 convolutional layers

COVID-19, the disease caused by SARS-CoV-2 (a new type of coronavirus), continues its spread throughout the United States. While COVID-19 test kits have been in limited supply, new studies from China suggest chest radiographs (X-rays) and chest computed tomography (CT) scans can help diagnose the disease Lab testing for COVID-19 (also known as the novel coronavirus or SARS-CoV2) has increased greatly since the virus spread across the globe in spring 2020. Current evidence suggests that chest CT scans and x-rays are generally NOT specific enough to either diagnose or rule out COVID-19 on their own COVID-19's rate of transmission depends on the timely detection of the carrier and the immediate implementation of interventions. Even though the CT scan is more sensitive to COVID Pneumonia, our approach considered Chest X-rays, for a possible preliminary classification, due to its prevalent usage as a primary diagnostic test Apparently, even asymptomatic patients show a severe chest X-ray 70 to 80 percent of the time. Dr. Bankhead Kendall also adds that if a post-COVID patient is experiencing shortness of breath, they should stay in touch with their primary care doctor
