One Health Harmful Algal Bloom System (OHHABS)
The One Health Harmful Algal Bloom System (OHHABS) collects information to help CDC and partners better understand harmful algal blooms (HABs) and help prevent human and animal illnesses caused by HABs.
What Is OHHABS?
OHHABS is a voluntary reporting system available to state and territorial public health departments and their environmental health or animal health partners.
OHHABS collects data on:
- Human illnesses caused by HABs
- Animal illnesses caused by HABs
- Environmental data about HABs
OHHABS is a One Health surveillance system. A One Health approach recognizes that the health of people is connected to the health of animals and our shared environment. This connection requires many types of partners to work together to improve health for all.
Find data on the OHHABS Data webpage.
Public health professionals can use our health promotion materials and OHHABS partner toolkit to share information with interested groups, including:
- The public
- Physicians
- Veterinarians
- Other partners
CDC launched OHHABS in 2016 to better understand HABs and help prevent illnesses that HABs can cause in people and animals. Learn more about OHHABS:
