Updated: Feb 1, 2023

Environmental Health provides the basis for public health. Environmental Health Officers (EHOs) implement environmental control to help safeguard the health of the community by maintaining a safe, healthy and supportive environment for us to live in.

Environmental Health Officers keep basic necessities of life like water, food, air, land and public facilities safe of public health risks and hazards. EHOs engage in initiatives to protect, promote and educate on public health matters. In order to promote good health, hygiene and environmental practices, EHOs regulate and enforce laws and regulations governing public health, buildings and environmental management practices. Monitoring, investigation and surveillance form the core duties of EHOs for disease control and prevention. They implement measures to prevent communities from getting sick from their environment. They help control vectors that can cause and spread diseases, for example, mosquitoes and rodents.


Why are EHO important?


The main aim of an Environmental Health Officer (EHO) is to assist in disease control and prevention so that people area protected from sicknesses that can be caused by a poor hygiene standards and environmental practices. Diseases require an agent, host and environment to spread. An agent could be a microorganism (virus, bacteria) , chemical or physical cause of a disease. A host could be a human or animal that can get the disease. For an agent to get to its host, it requires an environment such as water, food, air, sewage.

EHOs focus on the environment and find answers as to how and why a disease occurs. They recommend corrective actions to stop the spread of the disease and shield the host through environmental controls and education. This step stops the agent from causing harm to the host. For example Japanese encephalitis virus are spread by mosquitoes to its human host. To stop the spread of the virus environmental controls include educating public to cover up with loose fitting clothing, spray insect repellent, avoid going out in peak times such as dusk and dawn. Remove water holding containers from around the home and screen your home.
