In the news last month, there were a number of reports of Legionnaires’ disease, with a major outbreak in Portugal. Positive tests of legionella bacteria continue to be reported as a result of building closures due to lockdown, and one UK care home group incurred a heavy fine as a result of a fatality three years ago.

10 dead in Legionnaires’ outbreak in Portugal

Over the past months, 10 people have died and more than 88 have been infected in an outbreak of Legionnaires’ disease in the Portuguese city of Matosinhos. More than 75% of those infected are people over the age of 50. The source of the outbreak was tracked down to a factory’s cooling towers – as soon as they were switched off, the infection rate fell significantly. An investigation into the causes of the outbreak is underway.

Legionella found in US school

The legionella bacteria has been found in the pipes of a high school in Michigan.

Two cases of Legionnaires’ disease have been notified to the authorities in South Eastern Sydney. In both cases, the victims had spent time in the Hurstville town centre, and local residents have been told to be on the lookout for potential symptoms. Testing is being carried out in cooling towers and air conditioning units in the area to try and identify the source.

Two student halls of residence at St Andrews University in Scotland have been affected by the discovery of the legionella bacteria in their water systems after routine testing. Temporary shower facilities have been set up for the affected students, who have also been provided with bottled water while work to flush and clean the systems is being carried out.
