sanjay gupta is here to talk about this. it's frightening when we think of the u.s.nd west nile and these cases cropping up. before we talked about aerial spraying. how do you know if you have west nile? >> it can be hard to know. the vast majority don't know it because they have hardly any symptoms or they are mild and vague. people have sort of moderately severe symptoms. they get fever, swollen lymph nodes. in rare cases about 150 according to some of the papers you can get a neuro invasive form. it gets into the brain and spinal cord. eventually that's going to lead to these deaths as well. that's pretty unusual. what i think is important is there's an incubation period. it can be up to two weeks after you get bit. people may have gotten bit some time ago and then developed symptoms and think there's no way that could be west nile. they can sort of harbor it in the body for some time and then if you do get the symptoms they can last a few weeks as well. >> pay attention to what your body is telling you. >> if you have something unusual about this it has to be on
