However, these questions are not controversial in the scientific community.

Masks work

Check out this blog post from Those Nerdy Girls, a group of female scientists who answered common questions throughout the pandemic.

Pandemic viruses typically jump from an animal to humans (known as a “spillover event”), but one of the missing pieces of information about how SARS-CoV-2, the virus that causes COVID-19, made the leap was knowledge related to which animal might have incubated it before it started infecting humans. This limitation of existing knowledge, coupled with a lack of transparency and cooperation by the Chinese government, allowed for a “lab-leak” theory to gain steam.
