Feeling Hoarse? You Might Have the New ‘Stratus’ Covid Variant


The World Health Organization has added the variant, known formally as XFG, to its monitoring list. A dry, irritated throat is among its main symptoms.

“Spike mutations at amino acids 478 and 487 enhance antibody avoidance”—meaning, in other words, the variant may be more adept at evading our immune defenses. Available data doesn’t suggest that the variant causes more severe disease or deaths than others in circulation, though doctors in India have noted that hoarseness is a common symptom. Patients have also reported suffering a dry cough and sore throat, in addition to the more common Covid symptoms such as fever, muscle aches, and fatigue.
