1. Introduction

The welfare of mankind cannot be achieved without a health Environment. Most of the diseases of mankind, whether communicable or non-communicable, are closely related to man’s environment.

  1. Aim of the Course

To introduce students to the concepts and principles that seek to define and understand the mechanisms by which biological, chemical and physical agents, either naturally occurring or introduced into the environment by the socio-cultural activities of man cause disability and disease and the means whereby their effects may be prevented and controlled.

  1. Course Description:


The wide range of factors in the environment which affect heath either directly or indirectly will be discussed with a view to making distinction between the narrower traditional concept of environmental health and the present day broader concept that recognises the relationship between man and his total environment. For instance, transmission of diseases by transmission factors (such as objects contaminated with infective material) and the mechanism of transmission will be discussed, articulated and demonstrated.

Included within the course is a series of lectures on the impact of climate, water supply, housing, wastes disposal and management, food hygiene, air pollution and vector/rodent control on human health. Supplementing the lectures are on-site visits to provide students with knowledge of the operation of water purification and wastes treatment facilities and solid waste handling. Besides, students will be exposed to community-based family visits to relate lectures on environmental health to household practices of environmental hygiene.
