💉 Heartworm Disease Regional Risk Map Simulator

Mosquito Vectors Carry Dirofilaria immitis to a New Host

A short placeholder: mosquitoes transmit heartworm larvae during feeding.

• 30+: Mosquito species involved (Placeholder short caption)
• 10-30d: Microfilariae to L3 time (Placeholder short caption)
• L3 larvae: Bite-to-infection step (Placeholder short caption)
• Warm months: Peak vector season (Placeholder short caption)

How mosquitoes acquire and pass on larvae

Placeholder short sentence describing mosquito uptake of microfilariae.

Placeholder short sentence describing development to infective L3 stage.

Placeholder short sentence describing transmission at next blood meal.

Larvae Migrate Through Tissue Toward the Heart and Lungs

Placeholder short sentence: larvae travel from skin to pulmonary vessels.

• ~6 months: Migration duration (Placeholder short caption)
• Pulmonary artery: Final adult location (Placeholder short caption)
• 5-7 years: Adult worm lifespan (Placeholder short caption)
• up to 30cm: Adult worm length (Placeholder short caption)

Subcutaneous to cardiopulmonary journey

Placeholder short sentence describing subcutaneous molting stages.

Placeholder short sentence describing vascular migration route.

Placeholder short sentence describing maturation in heart and vessels.

Climate and Mosquito Density Define Regional Risk

Placeholder short sentence: warmer humid regions show higher risk density.

• Gulf Coast: High-risk US regions (Placeholder short caption)
• Temp & humidity: Risk driver (Placeholder short caption)
• ~1M dogs: Reported cases/year (Placeholder short caption)
• Annual: Risk map update (Placeholder short caption)

Mapping regional transmission pressure

Placeholder short sentence describing climate-driven mosquito density.

Placeholder short sentence describing regional incidence surveillance.

Placeholder short sentence describing local risk variability.

Year-Round Dosing vs Seasonal Prevention Gaps

Placeholder short sentence: year-round dosing avoids seasonal coverage gaps.

• Year-round: Vet consensus (Placeholder short caption)
• High: Missed-dose risk (Placeholder short caption)
• 2-4: Seasonal gap months (Placeholder short caption)
• Higher: Compliance improvement (Placeholder short caption)

Why continuous prevention is recommended

Placeholder short sentence describing risk of seasonal dosing gaps.

Placeholder short sentence describing unpredictable mosquito activity.

Placeholder short sentence describing year-round protection benefit.

Monthly Preventive Medication Maintains Protection

Placeholder short sentence: monthly doses sustain larvicidal drug levels.

• Monthly: Dosing interval (Placeholder short caption)
• Recommended: Annual testing (Placeholder short caption)
• Macrocyclic lactone: Drug class example (Placeholder short caption)
• ~99%: Prevention efficacy (Placeholder short caption)

Building a reliable monthly schedule

Placeholder short sentence describing monthly dose timing.

Placeholder short sentence describing combined annual testing.

Placeholder short sentence describing long-term adherence tracking.

Placeholder short highlight: consistent monthly dosing plus annual testing minimizes risk.
