Two die in Legionnaires' outbreak
Two people have died and 29 others are unwell after an outbreak of Legionnaires' disease in Madrid.
The city health department said more than 230 air conditioning systems in the capital have been inspected in an attempt to locate the source of the outbreak.
Two men have died from the disease, one on October 19 and the other on October 24.
Of the 29 people being treated, 21 are in hospital.
Legionnaires' disease is named after an outbreak at an American Legion convention in 1976 where 34 people died.
It is caused by a bacterium most often found in sources of standing water and can be contracted by breathing air contaminated by the bacterium.
The elderly and people with weak immune systems or lung problems are most susceptible.
