Per the 2022 Global Risks Report: “For the next five years, respondents again signal societal and environmental risks as the most concerning. However, over a 10-year horizon, the health of the planet dominates concerns: environmental risks are perceived to be the five most critical long-term threats to the world as well as the most potentially damaging to people and planet.”
CDC STUDY NOTES RISE IN LEGIONNAIRES’ A recently released CDC study of Legionnaires’ disease (LD) shows a steady rise in incidence for more than 15 years. The study, which appears in the March 2022 issue of Emerging Infection Diseases journal revealed that the disease, a severe pneumonia caused by a bacterium that can proliferate in building areas where warm, can live in areas where still water is aerosolized and inhaled, such as in cooling towers. The study also revealed racial and geographical disparities, with the highest incidences in Black people and in certain areas of the country.
The authors point out that “separating the effect of improved
surveillance from a true increase in infections is difficult” and that the disease might be under-diagnosed. The study notes that “the geographic focus and seasonality
suggest that deeper investigations into the effects of weather may further elucidate the rising incidence of LD.” While the study doesn’t mention this, the increasing interest in se-
nior living in the possibilities of health improvement through ventila- tion systems could have the side effect of reducing LD incidence.
