Leptospirosis programme reports: evaluating a prevention claim
A large programme does not by itself establish that a homeopathic preparation prevented infection.
The claim under review
The old page treated reports from Cuba as evidence of leptospirosis prevention. Programme size cannot eliminate confounding: rainfall, exposure, surveillance, diagnosis and other prevention efforts may change at the same time. A reduction in recorded cases needs an appropriate comparison before it can be attributed to the preparation.
What would establish prevention?
A prevention claim needs clearly defined infections, comparable exposure, a suitable control group and transparent reporting of outcomes. Changes in case counts can reflect how people were tested or which other measures were introduced. A testimonial, an uncontrolled outbreak report or an animal experiment cannot settle the practical question of whether a reader is protected.
Use current prevention guidance
Homeopathic preparations do not replace vaccination. Use the Australian Immunisation Handbook and a qualified clinician for prevention decisions. Do not delay testing, post-exposure care or treatment while trying an archived remedy.
