NSW Health said there had been 17 cases of Legionnaires' disease identified across Sydney and in the Illawarra last month.
Legionnaires' disease is caused by Legionella pneumophila bacteria and can cause severe respiratory symptoms. Outbreaks have been linked to contaminated air conditioning plants in large buildings. The disease does not spread from person-to-person.
Director of Health Protection Dr Richard Broome said Public Health Unit staff investigate each case of Legionnaire's and no specific source had been identified.

"However, it's timely to remind businesses and building owners of their obligations under the Public Health Regulation 2012 to ensure their cooling towers are properly maintained," he said.
"Legionnaire's disease is diagnosed by chest x-ray and a urine test, and usually requires antibiotic treatment in hospital. If you have tested negative for COVID-19 but have ongoing or worsening symptoms, you should see your doctor or visit your local emergency department."
Monthly tests of cooling towers are required.
Symptoms of Legionnaires' can develop up to 10 days after exposure, and can be similar to those of COVID-19 and include fever, chills, a cough and shortness of breath.
The Mercury asked NSW Health how many of the cases were in the Illawarra but did not receive a response.
