What can be inferred from patients with chronic Lyme disease (CLD)?

In paragraph 2, the author states that if Lyme disease is not treated properly, patients can suffer from chronic Lyme disease.
Antibiotic treatment must have been ineffective is incorrect. Although antibiotic treatment is mentioned in paragraph 3, it is not a given fact that someone with CLD was treated with antibiotics. For example, the patient could have skipped treatment altogether.
They did not have noticeable symptoms is incorrect. The passage does not state that patients with CLD did not have noticeable symptoms. Rather, the passage references that these patients can have debilitating long-term symptoms.
The tick was attached for up to 48 hours is incorrect. In paragraph 4, it is stated that most cases of Lyme disease require a tick to be attached for 36 to 48 hours, but the author does not connect this fact with patients with CLD.
