The Centers for Disease Control and Prevention (CDC) is investigating two cases of Legionnaires’ disease reported by passengers who sailed on the cruise ship Carnival Horizon in July and August. Legionnaires’ disease is a severe, often fatal, form of pneumonia associated with breathing in contaminated, aerosolized water from hot tubs, fountains, and other sources. It is not contagious.

Symptoms of an infection include fever, cough, shortness of breath, headache, and muscle aches. These symptoms usually develop within two to 14 days of exposure. Some people, including former smokers, people over 50, and people with compromised immune systems are at elevated risk of contracting Legionnaires’ disease. Most people who develop Legionnaires’ disease require treatment in a hospital setting. One in ten cases is fatal.

Legionella, the bacteria that causes Legionnaires’ disease, grows best in man-made structures such as the plumbing and air conditioning systems of large buildings and cruise ships. Especially if the water has been stagnant.

Carnival Cruise Lines has stated that the ship has undergone extensive testing and mitigation measures.
