“Girls” creator Lena Dunham says she was diagnosed with coronavirus in March and is still feeling its aftereffects. The actor-writer took to Instagram to share her “Covid Story” and detailed her experience battling the virus as someone who suffers from chronic illness. “Seeing the carelessness with which so many in the United States are treating social distancing . . .I feel compelled to be honest about the impact this illness has had on me, in the hopes that personal stories allow us to see the humanity in what can feel like abstract situations,” Dunham wrote.
