Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: How can I tell if I have new onset of asthma vs. COVID-19? I've had low fever, had to clear my throat but not cough, and have tightness in my chest / difficulty breathing and occasional pain in my lungs. There is no wheezing at all, no runny nose or congestion, my airways feel dry. I have no history of asthma, I'm 26 and exercise regularly (been recently training for cardio). The symptoms started in earnest about a week ago and got slightly worse the last few days. I'm trying to figure out if it could be just sudden onset of asthma or if I should be concerned that I have COVID-19. Any thoughts on to what extent these symptoms may resemble asthma?. ### Response: New onset asthma in adults rare Infection common.
