Final answer:
The provided information does not mention Kya or tetanus, but instead Kayla, who had Lyme disease and was successfully treated with doxycycline.
Step-by-step explanation:
The question seems to be referring to a scenario from a novel or story, perhaps involving a character named Kya. However, the details provided do not mention Kya but talk about Kayla, who had Lyme disease, not tetanus. Kayla was prescribed doxycycline, an antibiotic, and fully recovered after taking it. To prevent further tick-borne infections, Kayla was advised to use insect repellant and wear protective clothing during outdoor activities. Additionally, checking for ticks after being outdoors is crucial because prompt removal can greatly reduce infection risks.
