| ===Widespread disease and endemic regions===
| | __NOTOC__ |
| *The number of reported cases of [[Disease|the disease]] have been increasing, as are endemic regions in North America.
| |
| *''B. burgdorferi'' sensu lato has been maintained in enzootic cycles in California as well as other regions throughout North America, Europe and North Africa. Indeed, the [[DNA]] of ''[[Borrelia]]'' has been detected in lizards, indicating that they can be infected.<ref>{{cite journal |author=Swanson KI, Norris DE |title=Detection of Borrelia burgdorferi DNA in lizards from Southern Maryland |journal=Vector Borne Zoonotic Dis. |volume=7 |issue=1 |pages=42-9 |year=2007 |pmid=17417956 |doi=10.1089/vbz.2006.0548}}</ref>

|
| *In Europe, cases of ''B. burgdorferi'' sensu lato [[infected]] [[Tick|ticks]] are found predominantly in Norway, Netherlands, Germany, France, Italy, Slovenia and Poland, but have been isolated in almost every country on the continent. Lyme disease statistics for Europe can be found at [http://www.eurosurveillance.org/ew/2006/060622.asp Eurosurveillance website].

| *In South America tick-borne disease recognition and occurrence is rising.

| |
| *In Western and sub-Saharan Africa, tick-borne [[relapsing fever]] was first identified by the British physicians Joseph Dutton and John Todd in 1905.
| |
| *''Borrelia'' in the manifestation of Lyme disease in this region is presently unknown but evidence indicates that Lyme disease may occur in humans in sub-Saharan Africa. The abundance of hosts and tick vectors would favor the establishment of Lyme infection in Africa.<ref>{{cite journal |author=Fivaz BH, Petney TN |title=Lyme disease--a new disease in southern Africa? |journal=Journal of the South African Veterinary Association |volume=60 |issue=3 |pages=155-8 |year=1989 |pmid=2699499}}</ref> In East Africa, two cases of Lyme disease have been reported in Kenya.<ref>{{cite journal |author=Jowi JO, Gathua SN |title=Lyme disease: report of two cases |journal=East African medical journal |volume=82 |issue=5 |pages=267-9 |year=2005 |pmid=16119758}}</ref>
