As of 2020 18 tick-borne pathogens have been identified in the United States according to the Centers for Disease Control [10] and at least 27 are known globally. [8] [11] [12] New tick-borne diseases have been discovered in the 21st century, due in part to the use of molecular assays and next-generation sequencing. [13]
Other tick-borne illnesses, like southern tick-associated rash illness and Rocky Mountain spotted fever, can also cause distinctive rashes, the CDC notes. Tick bite pictures
People can get infected with Babesia parasites by the bite of an infected tick, by getting a blood transfusion from an infected donor of blood products, or by congenital transmission (an infected mother to her baby). [4] Ticks transmit the human strain of babesiosis, so it often presents with other tick-borne illnesses such as Lyme disease. [5]
Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
As ticks must be attached for at least six hours to transmit Rocky Mountain spotted fever and more than 24 hours to transmit Lyme disease, frequent checks are crucial in avoiding tick-borne illnesses.
If you're unsure what a tick bite looks like and are worried one you, these photos can help you identify a bite and tick bullseye rash before you see a doctor.
Tick paralysis is a type of paralysis caused by specific types of attached ticks. Unlike tick-borne diseases caused by infectious organisms, the illness is caused by a neurotoxin produced in the tick's salivary gland. After prolonged attachment, the engorged tick transmits the toxin to its host. The incidence of tick paralysis is unknown.
