A surgeon has stunned social media with a photo of a man covered in monkeypox blisters on a city tube train surrounded by other passengers.

Venezuelan surgeon Arturo Henriques, 32, took to Twitter to post the snap he had taken on his mobile phone on the Madrid Metro as a warning to netizens.

He wrote on 30th July: “15th July, 6.20am. The gentleman gets on the train at Legazpi station. Completely full of wounds from head to toe, including his hands.

“I see the situation and I also see people around him as if nothing will happen to them.”

He went on: “I turned into a Karen, I went up to the gentleman prudently and asked him what he was doing on the metro if he has monkeypox.

“His response: yes, I have it, but my doctor did not tell me I had to stay home. He only told me to use a mask.”

The medic continued: “I tell him the wounds he has all over his body are what are most infectious.

“I’m a doctor and he possibly did not understand all of his GP’s advice. To which he replied that I stop bothering him.

“I speak to the lady sat next to him.

“Me: Miss, are you not worried you’ll get sick? Lady: How am I going to catch it if I’m not gay? A woman from the government said it was gays who have to watch out.

“I arrived at my stop and stopped arguing.”

Dr Henriques’ thread has racked up more than 73,600 ‘likes’.

The NHS website says monkeypox can be passed on from person to person through any close physical contact with blisters or scabs.

It can also be transmitted through touching clothing, bedding or towels used by someone with monkeypox.

And even the coughs or sneezes of a person with monkeypox can be infectious.

But the NHS adds: “Anyone can get monkeypox. Though currently most cases have been in men who are gay, bisexual or have sex with other men”.
