Federal officials blame hotter weather, jet travel, forested suburbs and slow vaccine development for the presence of ticks thriving in regions previously too cold for them ...NY Times
The number of people being infected by diseases from mosquitoes, ticks and fleas has tripled in the United States from 2004 to 2016, according to a new report by the Center for Disease Control. There were more than 640,000 cases of these diseases reported during the 13 years analyzed. CDC
The incidence of tick borne infections in the United States has risen significantly within the past decade, according to the National Institutes of Health. Greater tick densities and their expanding geographic range have contributed to the increase. For example, the Ixodes scapularis tick, the primary source of Lyme disease in the northeastern U.S., had been detected in nearly 50% more counties by 2015 than was previously reported in 1996. The Centers for Disease Control and Prevention reports approximately 30,000 cases of Lyme disease annually but estimates that true incidence is 10 times this figure.

Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites.
According to the CDC, tick borne diseases can result in mild symptoms treatable at home to severe infections requiring hospitalization.
Although easily treated with antibiotics, these diseases can be difficult for physicians to diagnose. However, early recognition and treatment of the infection decreases the risk of serious complications. See your doctor immediately if you have been bitten by a tick and experience any of the symptoms described here:
- Fever/chills: With all tick borne diseases, patients can experience fever at varying degrees and time of onset.
- Aches and pains: Tick borne disease symptoms include headache, fatigue, and muscle aches. With Lyme disease you may also experience joint pain. The severity and time of onset of these symptoms can depend on the disease and the patient's personal tolerance level.
- Rash: Lyme disease, southern tick-associated rash illness (STARI), Rocky Mountain spotted fever (RMSF), ehrlichiosis, and tularemia can result in distinctive rashes.
