The awareness of autism has increased significantly which partially due to the increasing amount of research related to curing and understanding the disease. It is also partially due to famous celebrities with autistic children such as Jenny McCarthy and John Travolta. There is a growing fear that autism is becoming more and more common, based upon the growing percentage of children who were professionally diagnosed. Similar to McCarthy, both scientists, parents, and doctors alike have been trying to blame MMR vaccines, which are commonly given to children to prevent the catching of measles, mumps, and rubella. Others are speculating that it is merely a higher level of awareness for the disease that is causing numbers to go up. Is it something we're doing health-wise to give children autism, or are we simply becoming hyper-aware of behaviors that are related to it? Even so, these MMR vaccines given to children don't explain the kids who display signs of autism before receiving the shot. If they were born with autism, then perhaps the parents who received the same vaccine passed it on, which would indicate it is hereditary. Regardless, there is a growing paranoia in parents that their children may be autistic to a point where it seems more important for parents to discover if they are autistic instead of simply valuing their child's health.
