TB Simulation: A Journey
Inside the Body

Control how TB spreads, watch the immune response, and see the power of treatment completion — all through an interactive, cinematic experience.

How TB Spreads

Adjust ventilation, distance, and masks to see how transmission risk changes in real time.

Inside the Lungs: Immune Response

Watch as TB bacteria enter the lungs and the immune system fights back. Toggle immune strength to see different outcomes.

The Treatment Journey

Scrub through 6 months of TB treatment. Watch bacteria being destroyed — and see what happens if treatment stops early.

⚠ Warning: Incomplete treatment increases the risk of drug-resistant TB. Bacteria can mutate and become much harder to treat.

The Cost of Incomplete Treatment

Compare the outcome of completing treatment vs stopping early. Drug-resistant TB is far harder and more expensive to treat.

Complete Your Treatment

TB is curable with 6 months of proper treatment. Stopping early can lead to drug-resistant TB that takes 3-4 times longer to treat, costs more, and has much lower cure rates. Always finish your full course of medication.
