Covid-19 does exist and germs can cause disease

14 February 2025
What was claimed

Covid-19 does not exist.

Our verdict

False. Covid-19 is a real disease caused by the SARS-CoV-2 virus, which has been isolated many times.

What was claimed

Germs do not cause disease.

Our verdict

Many infectious agents, or germs, do cause diseases in humans. This has been proven many times.

A post on Instagram shares a video clip in which a woman claims, among other things, that “COVID-19 does not exist” and “germs don't cause disease”.

Both these claims are false, as we have said several times before.

The clip seems to come from a longer video interview that the late Dr Lorraine Day gave in March 2021 with a religious website called Israeli News Live [1:02:30].

Claims by Dr Day and Israeli News Live have been checked by other fact checkers before

In this case, there is abundant evidence that Covid-19, the disease caused by the SARS-CoV-2 virus, does exist. As we have said before, the virus has been isolated many times and continues to be detected in hundreds of tests each week in England alone.

The claim that germs don’t cause disease is also false. Many diseases are caused by germs, (also known as infectious agents), which include viruses and bacteria. This idea was first established in the 19th century, and has been conclusively proven in the years since.

It is true that not all diseases are caused by germs, with others arising from causes that include nutrient deficiency, lifestyle factors or genetics.

But many treatments and preventative medicines based on the germ theory of disease are used effectively every day, including antibiotics, antivirals and vaccines.

False information can spread quickly on social media and may be harmful if people use it to make decisions about their health.
