thanks! So far i havent been sick :)
Only time will tell with something like that so I wouldn't worry too much.
Where they at home? It's possible, but unless you are immunocompromised or were licking the doorknobs around the house I wouldn't worry too much about it. Typically an inspection takes less than 15 minutes and if you are careful to wash before you eat, there isn't much chance for the virus to get to you. Just make sure you take your vitamins, eat well, and sleep well and you should be ok. If you did pick up the flu from them you might start developing symptoms in a few days. I'm not sure how fast the flu works though.
