The Brazilian Health Ministry has created a Web site to let people inform partners they've got a sexually transmitted disease via an e-mailed virtual postcard.
The official in charge of the ministry's STD and AIDs programs notes that many people have a hard time telling partners they're infected.
Mariangela Simao said in a statement this week that the e-mails may help people "to tackle these diseases directly and with minimum exposure."
One of the cards shows a young man reclining in his underwear. It reads: "Hi! I don't know if this is the best way to tell you, but I've learned that I have an STD."
The card suggests the recipient see a doctor.
