A research letter published yesterday in JAMA found that rates of COVID-19 co-infections with other respiratory pathogens are 21%, higher than previously thought, suggesting that identification of another pathogen may not rule out the presence of the novel coronavirus. Also, a letter yesterday in the Annals of Internal Medicine detailing survey results on 272 primary care physicians in Lombardy, Italy, who cared for about 400,000 COVID-19 patients found that 40% had symptoms suggestive of the disease, and most had to buy their own personal protective equipment (PPE) and educate themselves on coronavirus management.
