RFK Jr in robust health despite brain worm scare, says campaign

US presidential candidate Robert F Kennedy Jr says he is in "robust health" following reports that he suffered from a brain parasite more than a decade ago.

The New York Times reported that Mr Kennedy also previously suffered from mercury poisoning and heart problems.

Mr Kennedy has made health a key part of his campaign.

He has contrasted his physical fitness with that of Joe Biden and Donald Trump.

"Questioning Mr Kennedy's health is a hilarious suggestion, given his competition," his campaign said in a statement Wednesday.

"Mr Kennedy travelled extensively in Africa, South America, and Asia in his work as an environmental advocate, and in one of those locations contracted a parasite," the campaign said.

"The issue was resolved more than 10 years ago, and he is in robust physical and mental health."
