Honest question, is drinking human blood unhealthy and what are some risk?

RISKY!!!: Are you playing vampire? Not as cool as you think. The risks start with the drinker exposing them self to any and all of the diseases that the donor of the blood might have. Some of these are chronic, even fatal outcomes. Hepatitis b & c most common. Hiv is another, how does that sound? Still thirsty? How about herpes? Extremely common. Drink some red kool aid and you can still pretend.

Risks like raw meat: If we set aside the cultural/psychological "ick" factor, drinking blood is similar to eating raw meat: it can contain bacteria, viruses and other infections which may not be destroyed by stomach acid, and it can upset your digestive system. Infections from drinking somenone else's blood include anything from "food poisoning" to life-threatening and incurable diseases, such as hiv.
