The CDC has ordered its scientists to retract or pause publication of research manuscripts that mention certain terms, including 'gender' and 'LGBT', in order to comply with the Trump administration's policies. This move affects not only CDC publications but also manuscripts submitted to external journals. The policy has caused confusion and fear among CDC experts, who are unsure how to interpret the new guidelines. Many studies, including those on Covid-19 and other diseases, may be impacted by the censorship.
