An incident in Dunedin Hospital's emergency department last weekend has highlighted the pressures medical staff are under.
A witness to the incident said a Covid-19 denier who presented in the department subsequently tested positive for the disease and "absolutely lost the plot".
The witness said the man refused to wear a mask, abused the doctor treating him, coughed repeatedly and openly, and yelled out that it was all a hoax.
"Then he got very aggressive and was threatening to kill and assault the doctors and staff there."
