Impetigo

Amy Winehouse is diagnosed with a highly contagious skin disease called impetigo, leading to blisters and bruises on her cheek. It used to be common amongst kids, but apparently celebrities can get them, too!

Next time you go to greet someone with a kiss on the cheek, think about what sort of infectious diseases you might contract. It's not worth it! Greet someone with a Honolulu Handshake instead.
