01
Asplenic, post-transplant, HIV-positive, or actively chemotherapy-treated patients are at higher risk for severe babesiosis.
02
Notify the relevant specialist (oncology, transplant, ID) within 24 hours of any tick bite, regardless of symptoms.
03
Baseline labs (CBC, smear, LFTs) may be drawn even before symptoms.
04
Empirical treatment thresholds are lower; clinicians may treat sooner and longer.
05
Babesiosis can relapse in immunocompromised patients; expect possibly 6+ weeks of treatment if confirmed.
06
Reinforce future prevention: permethrin-treated clothing, daily checks, and avoidance of peak tick habitats.
