Portuguese authorities have announced cooling towers at a fertiliser plant were the likely source of an outbreak of Legionnaires’ disease that has killed five people and infected over 200, Reuters has reported.
Environment Minister Jorge Moreira da Silva told reporters all cooling towers in the affected area near Lisbon had been shut since Sunday to bring the flare-up under control.
Health Minister Paulo Macedo said the detection of new cases was decelerating, but there will be more in the coming days.
Health ministry data released late on Monday showed the number of those infected had increased to 233 from 160 the previous day, and one more person had died.
Three dozen were in intensive care in various hospitals.
