US President Donald Trump has been lambasted by the medical community after suggesting research into whether coronavirus might be treated by injecting disinfectant into the body.

He also appeared to propose irradiating patients’ bodies with UV light, an idea dismissed by a doctor at the briefing.

Another of his officials had moments earlier said sunlight and disinfectant were known to kill the infection.

Disinfectants are hazardous substances and can be poisonous if ingested.

Even external exposure can be dangerous to the skin, eyes and respiratory system.
