New blood donation regulations screening donors based on sexual history rather than sexual orientation have been implemented in Mexico, making it the first country in North America to end its ban on men who have sex with men donating blood.

The new regulations came into effect Dec. 25 and now means any HIV and Hepatitis negative gay or bisexual man who has a history of safe sex and is not a sex worker or injecting drug user may donate blood.

The rule was approved in August and then published in the Official Journal of the Mexican Federation on October 26.
