Japanese Pediatric Disease Infographic

Goal: Create a warm, child-friendly Japanese medical explanation infographic for a clinic exam room, explaining the difference between hand, foot and mouth disease and herpangina, including daycare attendance guidance.

Canvas: Vertical poster, portrait orientation, cream paper background, soft pastel palette, rounded hand-drawn style, pediatric clinic friendly. Use thick dark-brown handwritten Japanese typography, watercolor-like medical illustrations, and colored rounded rectangles. Overall title at top: 「手足口病とヘルパンギーナ」 with small decorative confetti marks and a pink wavy underline.

Layout: Stack exactly 5 numbered sections from top to bottom, each inside a rounded rectangular card with a different accent color. Use large circular number badges on the left: 1 pink, 2 blue, 3 orange, 4 green, 5 orange. Keep the design clear enough for parents to read quickly.

Section 1: Pink-bordered card. Heading text: 「手・足・口に小さな水疱、おしりにも」. Show exactly 4 medical illustrations in a row: an open palm with small red blister spots, the sole of a foot with red spots, an open mouth/throat with sores, and a diapered baby bottom/thighs with spots. Add a small sun icon and text below: 「夏〜秋に小さい子に多い」.

Section 2: Blue-bordered card. Heading text: 「原因はコクサッキーウイルス」. Smaller text: 「ありふれたかぜのウイルス」. On the right, draw one cute round blue virus character with small protrusions, smiling face, and blue accent marks.

Section 3: Yellow-bordered card. Create a Venn diagram with exactly 2 overlapping translucent circles: left circle pink, right circle blue, overlap pale green. Left circle text: 「のどの奥に 白い水疱 →ヘルパンギーナ」. Right circle text: 「手のひら・足のうらに発疹 →手足口病」. Under the diagram, add explanatory text: 「原因ではなく『どこに出たか』でつけた病名。ヘルパンギーナでも全身に発疹が出ることがあり、厳密には区別できない」.

Section 4: Green-bordered card. Heading text: 「特効薬なし・対症療法」. Smaller text: 「約1週間で治る」. Include exactly 4 supportive-care illustrations: a glass of water, a sleeping child under a blue blanket with moon and stars, a digital thermometer reading about 36.6°C, and a cheerful recovered child in a green striped shirt raising a fist.

Section 5: Orange scalloped-border card. Large heading text: 「登園の目安」. Include exactly 2 checklist conditions: 「① 熱がない」 and 「② 普通にご飯が食べられる」. Add a large emphasized orange message: 「発疹が残っていても 普通の生活・登園OK」. Add smaller note: 「ウイルスは治った後も長く出続けるので、発疹が消えるまで待つ意味はありません」. On the right, draw a happy young boy wearing a yellow hat, striped shirt, shorts, and blue backpack, walking toward daycare; include a small school building with clock and simple flowers.

Visual style: Cute Japanese nursery-health handout, soft watercolor shading, rounded corners, clean spacing, pastel pink/blue/yellow/green/orange accents, no harsh realism, no scary symptoms. Make all text legible and spelled correctly.

Customizable text slots: Use the title {argument name="poster title" default="手足口病とヘルパンギーナ"}, main disease name {argument name="main disease" default="手足口病"}, comparison disease name {argument name="comparison disease" default="ヘルパンギーナ"}, virus name {argument name="virus name" default="コクサッキーウイルス"}, and attendance headline {argument name="attendance headline" default="登園の目安"}.
