Australia’s minister for home affairs, Peter Dutton, who last week met Ivanka Trump, President Trump’s daughter and senior adviser, said he had contracted the new coronavirus.

Dutton, a hardline conservative and former police officer who has been relatively quiet in the midst of the outbreak, said on Twitter on Friday that he tested positive for the virus that causes Covid-19.

“I feel fine and will provide an update in due course,” he wrote.

Last week, Dutton met Trump and attorney-general William P. Barr in Washington. He is the latest in a string of foreign dignitaries who have met associates of Trump in recent days, only to later learn they had been infected. The government announced that all events with 500 people or more will be banned.

Prime Minister Scott Morrison said on Friday that isolation and the tracing of contacts have been shown to slow the spread of the virus. “And that’s why Australia right now is in a position where we have low rates of this virus and the number of cases that have presented. But we’ve always known that the number of cases will rise.”
