Whenever there is a new disease outbreak, be it AIDS, Ebola, Zika or now SARS-Cov2, there are always conspiracy theories about deliberate bioengineering or laboratory escapes, and a jump to apportion ‘blame’ for the disease. There is often particular...

President Trump’s comments strike at the heart of issues inherent in the US and global responses to covid-19. Firstly, the claim is false. However, more importantly Trump’s comments undermine trust in the US Government.

Adam LauringVirologist and professor of microbiology, immunology and infectious diseases at the University of Michigan Medical School.votes Against and says:
The SARS-CoV-2 virus has some key differences in specific genes relative to previously identified coronaviruses — the ones a laboratory would be working with. This constellation of changes makes it unlikely that it is the result of a laboratory 'esca...

There is no evidence of escape from a lab. The virus is just like a virus we would expect to see in wild bat populations, similar viruses have jumped from non-human animals to animals in the past, so I see no reason to speculate about this any furthe...
