CDC: Lyme Disease Incidence in U.S. is 10 Times Higher Than Previously Thought


Preliminary estimates released by the Centers for Disease Control and Prevention at the 2013 International Conference on Lyme Borreliosis and Other Tick-Borne Diseases indicate that the number of Americans diagnosed with Lyme disease each year is around 300,000.

Each year, more than 30,000 cases of Lyme disease are reported to CDC, making it the most commonly reported tick-borne illness in the United States. However, this new early estimate, based on findings from three ongoing CDC  studies,  suggests that the total number of people diagnosed with Lyme disease is roughly 10 times higher than the yearly reported number.

This new estimate also supports studies published in the 1990s indicating that the true number of cases is between 3- and 12-fold higher than the number of reported cases.

Are there any numbers on the cases of Galactose-alpha-1,3-galactose?

Here is a link to the CDC page about all of the tick-borne diseases they track: It looks like there is information about Ehrlichiosis, which is transmitted to humans by the lone star tick. Hopefully this will help you find the answer to your question. We will keep digging and will let you know if we find any other resources.
