Keeping a Tight Rein on Deadly Diseases
Stringent infection-control measures best way to fight spread, study finds
HealthDayNews — Strict infection-control measures in hospitals are the most effective way to combat new, deadly infectious diseases that resist treatment and for which there are no vaccines.
So says a study in the July 30 issue of the journal Proceedings B.
Health-care workers need to wear masks, gowns and wash their hands regularly to contain untreatable infectious diseases that can spread rapidly in a hospital, according to the American scientists who did the study.
These inexpensive and easily implemented precautions are the most effective of disease-control measures. They can substitute for other approaches such as expensive isolation facilities, quarantine and sequestering of health-care workers.
The University of California, Berkeley scientists used a mathematical model of severe acute respiratory syndrome (SARS) to reach their conclusions. In every scenario, they found a breakdown in general infection control was more damaging to efforts to contain the disease than a breakdown in any other measure meant to reduce disease transmission.
“New, untreatable infectious diseases pose a growing risk as globalization leads to unprecedented human mobility, and they will continue to challenge public health systems worldwide. Our study examined priorities and trade-offs — how one measure can compensate for another which isn’t available in a given setting — between alternative strategies of disease control,” researcher James Lloyd-Smith says in a news release.
