If you visited Melbourne’s new aquarium Apr. 11-25 and are feeling unwell, get to a doctor immediately. The bacteria that causes Legionnaires’ disease spread through the air conditioning system over that period, and already two people have died, eight are in critical condition, and more than 60 others have been confirmed to have the disease. Symptoms include muscle aches, fever, chills, headache and shortness of breath. The air conditioning system has been sanitized and the aquarium now is considered safe.
