COVID-19 Mortality Rates in Los Angeles County Among People Experiencing Homelessness, March 2020-February 2021.

Objective: Understanding COVID-19-related mortality among the large population of people experiencing homelessness (PEH) in Los Angeles County (LA County) may inform public health policies to protect this vulnerable group.

A brief history of autism, the autism/vaccine hypothesis and a review of the genetic basis of autism spectrum disorders.

Autism spectrum disorders (ASD) represent a common spectrum of developmental disabilities, sharing deficits in social interactions, communication and restricted interests or repetitive behaviors with difficult transitions. In this article, we review the history of the identification and classification of autism and the origin of the now widely-debunked autism/vaccine hypothesis. The differences between syndromal (complex) and non-syndromal (essential) autism are described and illustrated with case descriptions where appropriate.
