Viruses constantly change to adapt and survive. Because of this, variants emerge when a strain has one or more mutations that differ from others. Now, coronavirus mutations and variants have been found to be more contagious or deadly than the original strain.
The Delta variant, also known as B.1.617.2, can spread more easily and is thus, more contagious, according to the Centers for Disease Control and Prevention. The strain has specific mutations on the spike protein that make it easier for the virus to infect human cells. Hence, people who carry this strain may be more contagious and spread the disease to others more easily. If you think you might have symptoms of COVID-19, contact the testing services near you to get tested.
But what are the symptoms of COVID-19 caused by the Delta variant? The symptoms are more or less similar to those seen with the original strain and other variants – persistent cough, fever, headache, and sore throat. However, according to data from the ZOE COVID Symptom Study, cough and loss of smell and test seem to be less common. Headache, sore throat, fever, and runny nose seem to be more prevalent. Be sure to have access to free COVID testing near you in order to be prepared.
