Friends have just arrived from the USA and we haven't seen them in AAAAGES or met their beautiful new addition. Our girlfriend has had shingles though - developed about 3 weeks ago.

Does anyone know what the deal is with this? I know shingles + pregnant women are not supposed to mix but I'm wondering why / if there's anything I can do that will prevent catching the virus that will still mean that I can see them.

Any info much appreciated - google is just confusing me!
