These claims are highly misleading and are not supported by medical advice.

Using a disinfectant can kill viruses on surfaces. It’s a very good idea to keep things you touch clean, using products with anti-microbial properties - for example those with a high alcohol content.

There is also some evidence that, in general, viruses on surfaces die more quickly when directly exposed to sunlight. But we don’t know how much or how long they have to be exposed for UV light to have an effect, so you’re far safer just washing your hands and surfaces and trying not to touch your face.

Crucially, this is only about infected objects and surfaces – not about what happens once the virus is inside your body.

One of the main ways of catching the virus is by breathing in droplets expelled by an infected person, mainly by sneezing and coughing. The virus very quickly begins to multiply and spread, eventually reaching the lungs.

Not only does consuming or injecting disinfectant risk poisoning and death, it won't even reach the virus.

Equally, by the time the virus has taken hold inside your body, no amount of UV light on your skin is going to make a difference.

And since UV radiation damages the skin, using it to kill the virus could be a case of - to borrow a well-worn phrase - the cure being worse than the disease.
