"They have not isolated a “Covid 19” virus."
FALSE! The SARS-CoV-2 virus was isolated in December and its complete genome was released to the world on January 10th 2020. Source. It has been directly imaged by scanning and transmission electron microscopes. Here are some images of it:
Those two images were taken by NIAID’s Rocky Mountain Laboratories (RML) in Hamilton, Montana.
"The PCR test identifies some proteins found in corona viruses (and other inert materials)."
FALSE! The PCR tests used for COVID-19 specifically identify sequences only found in SARS-CoV-2 and do NOT trigger off other coronaviruses, nor "other inert materials" (whatever that even means). Source (look to page 11 for specificity of the test and for evidence that it does NOT trigger from other viruses).
Misinformation is being spread to sew FEAR and MISTRUST in President Trump's efforts to control the spread and eliminate the threat posed by COVID-19. Whenever someone makes extraordinary claims like these, CHECK them against REAL sources of information. Do NOT trust the media, and do NOT trust the tinfoil hat crowd! They are TERRIBLE sources of misinformation and FEARmongering!
