Mpox is a viral infection that is mainly spread through very close or intimate contact.

Infectious Diseases expert Dr Paul Griffin says this particular strain is known for its blistering.

"Clade 1 is notorious for causing a more widespread rash, so quite big blisters, or pox-like, so those big legions and with Clade 1, they typically see them all over," Dr Griffin said.

"And because it is more severe, they can have other symptoms like high fevers."
