Health authorities have issued a warning to those in the south-east after discovering the first recent measles case to be contracted in the state, rather than overseas.

A man contagious with the disease was in the Brisbane CBD, Fortitude Valley and Spring Hill region between March 13th and 21st.

The Metro North Public Health Unit is warning anyone in the area between those dates to be on the lookout for symptoms, which include sore and red eyes, a runny nose and fever, followed by a red, splotchy rash.
