The symptoms include fever, headache, muscle aches, backache, swollen lymph nodes, chills, tiredness, and a rash that starts on the face and spreads to other parts of the body.
The third person who died was a 40-year-old man from KwaZulu-Natal province who had mpox-like symptoms including a rash all over his body, the ministry said.
Mpox spreads through close physical contact. Most cases are mild but it can kill.
