What was with the legionella fear? (The Bullock brothers have a shower
in a greenhouse
, I'm going to assume with a solar hot water
system.) Legionella will grow in a hot water
system, that's for sure. It's happy growing in water
from 90 to 108 degrees Fahrenheit, and it can survive up to 122 degrees. Taking a shower
with Legionella infused water would definitely expose an individual to aerosolized bugs. So it's reasonable to have a concern.
The thing that drove me to write this reply is Paul's statement about "85% of pneumonia is Legionella." This statement baffles me. About 5% of community
acquired pneumonia is thought to be secondary to Legionella. The risk is higher in smokers, those with chronic lung disease, the elderly and immunocompromised. As a pediatrician I have never seen a case of Legionella pneumonia (at least not that I have diagnosed!). I'm glad to have done this reading, because the risk is not zero and in the future if I have a pneumonia with very high fever that is not responding to the usual antibiotics I will keep this in mind.
I think if the Bullock brothers limit shower use to those who do not experience
a hacking cough upon waking (either every day, or even just that day) then they're going to be just fine. Couple that with temperature monitoring and periodic clean outs and the risk will be reasonably mitigated. In my opinion. Everyone has a different tolerance of risk.
