"Kuwaniswa kwezuva kazhinji nevanhu kwavanoita kusiri kwekuziva uye kunoitika," anodaro Joshua Zeichner, M.D, director wezvekushongedza uye zvekurapa mukuongorora dermatology paMount Sinai Hospital muNew York City. "Vanhu havazivi kuti inguva pfupi dzinopedzwa panze - rwendo rwavo rwekuenda kubasa, vachimhanya-mhanya - apo zuva riri kukuvadza ganda ravo."
