Building Vacancy Feeding the StormLegionnaires'Disease Risk Growsas CoronavirusLockdowns LiftBy Don Rauf – Medically Reviewed by Justin Laube, MDLast Updated: August 27, 2020Experts warn that Legionella bacteria may pose adanger as workers return to offices and children goback to school.As COVID-19 stay-at-home orders lift in many parts of the country, people are tiptoeing backinto everyday life. But office workers heading back to their cubicles and kids going back toschool may face a new danger hidden within air-conditioning cooling towers, toilets,drinking fountains, and other plumbing systems: water contaminated withthe Legionella bacteria that cause Legionnaires' disease — a serious type of pneumonia.9San Antonio, Texas, 11 May 2022 Emerging Technology for Improving Potable Water Safety in Premise PlumbingLegionnaires' DiseaseMay Flourish inPlumbing Due toCOVID-19 ClosuresBy Adam Townsend on 08/04/2020 2:00 PMSource: MedicineNet Health NewsAs offices, shops, and restaurants sit unused during the COVID-19pandemic’s social distancing measures, some experts worry anotherdeadly microbial attacker may be literally waiting in the pipeline:Legionella pneumophilia, the bacteria that causes Legionnaires' disease.Researchers at the University of Pittsburgh in July announced they wereworking on a study to determine how to stop Legionella at the faucetthrough silver-impregnated antimicrobial showerheads and fixtures.Their work takes on extra importance as managers across industriesand disciplines figure out how to reopen their facilities safely.

Insurance companies place onus on hospital.Insurance Companies are Fighting LiabilitySome insurers are intensifying Legionnaires' precautionsbefore adding new clients or renewing coverage, insurers andbrokers said. For instance, they may ask customers todocument how they maintain plumbing and cooling systems.Insurers might limit Legionnaires' coverage amounts orimpose higher deductibles if building systems are outdated,brokers said.Insurers were already worried about possible outbreaks,because of elevated lawsuits and claims. They are steppingup their scrutiny even more due to the coronavirus pandemic.Source: U.S. insurers eye Legionnaires' disease safeguards as buildings re-open from pandemic shutdowns, Reuters JUNE 18, 2020.11San Antonio, Texas, 11 May 2022 Emerging Technology for Improving Potable Water Safety in Premise Plumbing
