In a paper published in the European Journal of Radiology, 295 patients with laboratory confirmed SARS-nCov-2 infection were identified in the Guangdong Province of China. All patients were imaged with computed tomography of the chest (CT scans). Interestingly, 17 percent of patients had a normal chest CT on initial evaluation. Additionally, 12 percent of all infected patients had normal chest CTs both on initial evaluation and on days 3 and 14 of infection, with few or no clinical symptoms. This cohort from the Guangdong Province provides further evidence of higher than previously reported rates of mild and asymptomatic covid-19 infection.
announced reports of patients losing their sense of smell and/or taste without other explanation such as allergies, acute sinusitis, or chronic rhinosinusitis. Such patients should be screened for covid-19 infection. The AAO even suggests that such patients should seriously consider self-isolation.

In normal circumstances, medical device makers are required to file a notification–known as 510(k) notices—with the Food and Drug Administration before making modifications to devices already on the market. Even changing the supplier of a single component or a material requires disclosure. Today, in an effort to encourage manufacturers to produce more mechanical ventilators more quickly, the FDA announced that manufacturers would temporarily not be required to file 510(k) notifications for limited modifications to ventilators, high flow nasal oxygen systems, anesthesia gas machines, and some other related devices. This allows manufacturers to find new suppliers, and possibly increase production immediately. This appears to be an important step in addressing the nation's impending shortage of mechanical ventilators needed to keep some patients alive. Food and Drug Administration.
