Preventing Resistance

Visual scenarios on how to stop antibiotic misuse.

hand-drawn ink style with watercolor washes, consistent character design, warm saturated color palette, expressive character poses, clear panel borders with subtle drop shadows, modern graphic novel quality, classroom-safe, 5-panel educational comic showing a person asking a pharmacist for antibiotics for a sore throat, the pharmacist refusing without a doctor's prescription, and a farmer deciding not to inject healthy cattle with antibiotics to prevent developing resistance.

Preventing resistance requires smart choices from both patients and farmers.

hand-drawn ink style with watercolor washes, consistent character design, warm saturated color palette, expressive character poses, clear panel borders with subtle drop shadows, modern graphic novel quality, classroom-safe, 3-panel educational comic focusing on biology: showing normal bacteria dying from antibiotics, a few mutant resistant bacteria surviving and multiplying, and finally transferring their antibiotic resistance directly to other bacteria.
