We’ve been lying to you all along!
We have always told you, and everyone we work with the same thing.
We’ve told this to our customers, to our blog readers, to people we work with and to everyone who has asked us.
“You cannot contract Legionnaires’ Disease from someone who has the illness. You can only get it from inhaling water droplets containing the Legionella bacteria.”
Well, FORGIVE US FATHER FOR WE HAVE SINNED. Everything we have told you may have been a LIE.
An outbreak of Legionnaires disease occurred in Vila Franca de Xira, Portugal between October and November 2014. The source of the outbreak was established as being an industrial cooling tower in the town infected by Legionella.
One of the first cases of disease in this cluster occurred in a 48-year-old man, a smoker, who had been employed since October 6, 2014, as a maintenance worker at the industrial cooling tower complex in Vila Franca de Xira.
He returned to the home that he shared with is mother in Porto (approximately 300 km from Vila Franca de Xira) on October 11 and again on the evening of October 19. His symptoms began on October 14, and on October 19, he had severe respiratory symptoms, including an intense cough.
During that night, his mother took care of him until he was admitted to the hospital approximately 8 hours later. On October 22, he was transferred to another hospital to receive extracorporeal membrane oxygenation.
On October 27, his mother, who was a previously healthy 74-year-old woman, began to report fever, cough, and loss of appetite. She was admitted to the same hospital on November 3 with septic shock due to pneumonia, and she died on December 1. Her son died on January 7, 2015.
Urine samples from both patients reported back positive results on testing for Legionella. As far as can be ascertained no water was taken from Vila Franca de Xira to Porto and the only connection with the outbreak was the son. Tests showed that the water in the mother’s house contained no Legionella and the mother had never been to Porto in her life.
As Legionella is transmitted by aerosols it is probable that the mother was exposed to infection through her son’s coughing. As reported in the New England Journal of Medicine this is, however, the first ever suggestion of a transmission of Legionella from person to person.
Of course, this is a very rare case and this isn’t to say that suddenly Legionnaires’ Disease is contagious. However it does mean people who are in close proximity of someone who may have Legionnaires’ Disease should be extra vigilant in protecting themselves.
