The popes assistant explains what happened to one of his brothers:

It started with a headache. Then chills and fever, which left him exhausted. He experienced nausea, vomiting, back pain, soreness in his arms and legs. Bright light was too bright to stand.

Within a day or two, the swellings appeared. They were hard, painful, burning lumps on his neck, under his arms, and on his inner thighs. Soon they turned black, split open, and began to ooze pus and blood. They had grown to the size of an orange.

Few ever recover.  It is possible to recover. But more than likely, death would come quickly like it did for my brother. Yet... perhaps not quickly enough. Because after the lumps appeared he would start to bleed internally. There was blood in his urine, blood in his stool, and blood puddling under his skin, resulting in black boils and spots all over his body. Everything that came out of his body smelled utterly revolting. He would suffer great pain before he breathed his last. And he died barely a week after he first contracted the disease.
