US President Donald Trump said he takes no responsibility for a spike in cases of people misusing disinfectants after he wondered aloud last week about possibly injecting them as a treatment for coronavirus.

When asked this week about the increase of people in some states ingesting disinfectants Trump answered: “I can’t imagine why”.

When pressed about whether he takes any responsibility, Trump said, “No, I don’t”.

Maryland was one US state that issued a warning against dangerous disinfectant use, with the Maryland Emergency Management Agency tweeting the agency had received “several calls”.

“This is a reminder that under no circumstances should any disinfectant product be administered into the body through injection, ingestion or any other route”, - reads the tweet.
