April 2 was World Autism Awareness Day, and people all over the planet donned royal blue to raise awareness for the disorder.

According to Autism Speaks, autism or autism spectrum disorder encompass a range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication, as well as by unique strengths and differences. Currently, there is no definitive method of detection, nor is there a cure.

In March 2014, the Centers for Disease Control and Prevention found that one in every 68 children in the U.S. has autism spectrum disorder, compared to one in 150 in 2000.

Yet as autism is becoming more and more common, many people still aren’t aware of Autism Awareness Day, or even the disorder itself. It’s often used as a teenage insult and misunderstood as a disease or illness.

April is Autism Awareness Month, but it isn’t just about wearing blue shirts and bracelets. Donating to local charities or volunteering as an autism buddy are ways to support the community.
