The Governor of the State of Goiás here in central Brazil, has just signed into law (no. 20.922/2020) a bill which EXEMPTS INDIVIDUALS WITH AUTISM FROM HAVING TO WEAR A MASK. The reasoning is that rights of the autistic cannot be trampled upon by forcing them to adept to a situation that they find difficult to adapt to. In regard to the draft of the legislation, there is no mention or consideration whatsoever to risk of infection.
