What is H1N1?

What are the chances I have H1N1, and when would I show symptoms? (If I had it)?

• My boyfriend was at this parents for a few days because he was working in their area. His brother, 8, has H1N1 symptoms. (Sever coughing and High Fever) He has been like this for 2-3 days. I don't know when his parents are going to get him checked for it, but I do know my boyfriend has been staying there for 4 days. His family is bad with washing their hands, never mind covering their mouth. My boyfriend came home 2 hours ago, and told me he was worried about his little brother because of his symptoms being very related to H1N1. I think the chances are high that is could have been passed to my boyfriend, and possible me, since I gave him a major kiss when he came home. So, if we did catch this, H1N1 or just a cold, when would I start feelings rough? (coughing, etc) I am suppose to see my brother tomorrow, and he has a very busy life and gets sick very easily. The last thing I'd want is to give him this. So, if hypothetically I had it, but didn't feel it coming until tomorrow night, could I still pass it on to him?

• Answer:

  I had H1N1, but i don't know when i contracted it, but when i first got it, i felt the fever first. If you start feeling dead, you have it. I know this is very vague, but beleive me, you will know. You should still get tested, though. Dont want to give it to your brother or anyone else, obviously Hopefully i helped, haha. I had to go home from school bc i felt really tired and sore and had an asthma attack during gym, so i went home and when i woke up i had a bad cough and pneumonia/H1N1. so basically, it could be a combo.
