Study provides key insights into the spread of Rocky Mountain spotted fever - News-Medical.Net
Findings from a new study are providing important insights into the spread of Rocky Mountain spotted fever, which is transmitted from dogs to people through ticks. The new data are being used to create models that could help predict, and possibly prevent, future outbreaks. If not treated within the first five days, Rocky Mountain spotted fever can cause serious organ damage in humans that may lead to death.
