Does every tick carry disease?
No. Not every tick is infected, and an infected tick does not automatically transmit a pathogen during every bite.

Key takeaways
Ticks and pathogens are not the same thing
Ticks are blood-feeding arachnids. Some can act as vectors when they acquire and transmit particular bacteria, viruses or parasites, but infection rates differ between places and populations.
Avoid false reassurance and unnecessary alarm
Commercial testing of a removed tick is not generally recommended by CDC for making treatment decisions. A positive tick result does not prove transmission, while a negative result can create false reassurance.
