[1] [2] [3] Another tomographycal finding recently related to COVID-19 pneumonia is the reversed halo sign (RHS). Although some authors have reported the appearance of the RHS in later stages of the disease, during the evolution of the pulmonary infectious process, 1,2 other authors have described its presence in the first days after symptom onset. 12 This finding suggests that the disease course of COVID-19 might be similar to those of other viral infections, with early progression to organizing pneumonia and presentation of the RHS.	./cache/cord-255525-7w5u789h.txt	./txt/cord-255525-7w5u789h.txt
