Making matters worse, it can be difficult for even doctors to reliably tell the difference between the flu and the coronavirus due to their many overlapping symptoms. Thankfully, the CDC has weighed in on the matter, and clarified that there are at least two COVID-19 symptoms that are definitely not shared with the flu: the loss of smell and shortness of breath.ae0fcc31ae342fd3a1346ebb1f342fcb To be clear: If you have fever, fatigue, aches, and gastrointestinal issues such as abdominal pains or diarrhea, it is possible that you could have the flu. (Though you should definitely seek medical attention, regardless.) If you have any of those and the loss of smell or a shortness of breath, it raises your chances that you have COVID-19. According to a European study of 417 people with mild to moderate cases of the disease, more than 85 percent of patients reported suffering from a loss of smell. According to a recent study published in the National Library of Medicine, half of the patients with severe cases of the illness will likely develop dyspnea—or a shortness of breath—about a week after the symptom start to arise. It’s worth noting that a shortness of breath indicates a severe respiratory issue that might need supplemental oxygen therapy and even a ventilator. So if you’re having trouble breathing, seek medical attention immediately. RELATED: For more up-to-date information, sign up for our daily newsletter.
