Humans can be exposed to HABs, and their associated toxins, through either direct contact, including swimming or wading, inhalation, and ingestion.

Symptoms of HAB toxin exposure may include vomiting, diarrhea, neurological symptoms (muscle weakness, dizziness), liver damage, or stomach pain.

According to the Center for Disease Control and Prevention, there are currently no designated treatments for HAB toxin exposure in people except for supportive care.

The Centers for Disease Control and Prevention has a guide on clinical information for medical professionals: https://www.cdc.gov/habs/specific-groups/healthcare_providers.html
