Psittacosis is an uncommon infectious disease that is most often transmitted to humans through exposure to infected birds, especially parrots, cockatiels, parakeets and similar pet birds. Psittacosis can affect the lungs and may cause inflammatory illness of the lungs (pneumonia). Additional common symptoms include fever, muscle pain (myalgia), headaches, and a dry cough. Psittacosis is caused by infection with the bacterium, Chlamydia psittaci, and may also be known as ornithosis. It is rare among humans. People who own birds as pets are most likely to be affected by psittacosis.
Prior to the October 2013 eruption, the last notable eruption from Mount Etna was in 1992. In total, there are about 3 active volcanoes in Italy that spew lava intermittently: The Vesuvius volcano close to Naples, Stromboli and Mount Etna in Sicily.
There are currently three active volcanoes in Hawaii. On Hawaii Island you'll find Maunaloa and Kilauea in Hawaii Volcanoes National Park. Maunaloa last erupted in 1984 and Kilauea has been continuously erupting since 1983. Loihi is located underwater off the southern coast of Hawaii's Big Island. Erupting since 1996, this emerging seamount may break the surface in about 250,000 years, adding a ninth island to the Hawaiian chain.
