Legionnaire's disease is threatening people living in Bronx. On Wednesday, a person lost his life in the second recent outbreak of Legionnaire's disease in Bronx. The death was confirmed by office of Bill de Blasio, Mayor of New York City.

In the second outbreak since summer, about thirteen cases have been reported of the serious lung infection caused by Legionella bacteria. Bill de Blasio revealed Thursday during his visit to a Bronx senior center that nine people suffering from the disease are still in hospital, while three have been discharged. According to the office of the mayor, sufferers had underlying health conditions.

The mayor said the second outbreak is not powerful and as serious as the first over the summer. About a dozen people lost their lives during the first outbreak while a number of sufferers visited hospitals. "In the most recent outbreak, there have been no new cases in the last nine days and there has been no surge in emergency room cases. We're going to be very vigilant, be very careful", according to de Blasio.

In the second outbreak, six facilities' fifteen cooling towers were found positive. After the examination, they were shut down by officials. In the most recent outbreak, the first case was reported on September 21.

In August, the mayor ordered to inspect and clean all cooling towers. Middle-aged or older Individuals, who smoke, or have chronic lung disease, are most at-risk.

"We're going to be very vigilant, be very careful," the mayor said.

"We urge anyone who feels sick to visit their doctor or a hospital to get checked," he said. "It is too important to wait."
