By looking at nearly 56,000 COVID cases documented by the World Health Organization in China, the researchers found that the coronavirus tends to cause fever first, followed by upper respiratory tract symptoms (like cough), then gastrointestinal symptoms.The analysis—which also found that COVID-19 is two to three times more contagious than the common flu—found that fever and cough were consistently the first two symptoms, but in some people may be followed by sore throat, headache or muscle pain before progressing to GI symptoms."The most likely path of COVID-19 symptoms is fever, then cough, and next either sore throat, myalgia [muscle pain], or headache, followed by nausea/vomiting, and finally diarrhea," the scientists wrote.
They noted that the order of symptoms did not seem to affect the severity of disease.Complicating this aim is a fact that has bedeviled doctors and scientists since the beginning of the pandemic: Up to 40 percent of people infected with COVID-19 may experience no symptoms at all, allowing them to spread the disease unknowingly.The most common flu symptoms are body aches, chills, cough, fatigue, fever, and headache but there are other symptoms like sore throat and vomiting.In today's Deep Dives episode, we take a closer look at the effects that chronic stress could potentially have on your body - including psychogenic fever symptoms and a weakened immune system.
