Studies have also suggested that autism may be due to a compromised immune system. Evidence also suggests that viruses may play a role in causing autism; after being exposed to rubella during the first trimester of a pregnancy, the likelihood of having a child with autism increases. Because the prevalence of Autism is higher in cities with high levels of pollution and toxins, it has been hypothesized that there could be link between toxin levels and the risk of having autistic
