Human health is about keeping our bodies and minds well so we can learn, work, and live happily. In Ghana, many learners miss school or perform poorly because of common diseases such as malaria, diarrhoea, typhoid fever, respiratory infections, and skin infections. Understanding what makes a disease “common” in a community helps us to prevent illness, reduce hospital visits, and protect families.
A. Meaning of “Disease” A disease is a condition that affects the normal functioning of the body or mind and produces signs and symptoms. Signs: what others can observe (e.g., rash, swollen eyes). Symptoms: what the sick person feels (e.g., headache, nausea, body pains). B. What is a “Common Disease” in a Community? A common disease is a disease that occurs frequently among people in a particular community over a period of time.
A disease may be common because: The cause/agent is present (e.g., mosquitoes carrying malaria parasites). The community has risk factors (e.g., stagnant water, poor sanitation, overcrowding). There is low prevention practice (e.g., few people sleep under treated nets). There is limited access to clean water, healthcare, or health education. Important point A disease can be common in one community but not common in another. For example: Malaria may be common in a community with many mosquito breeding sites. Diarrhoea may be common where water sources are contaminated. C. How to Decide if a Disease is “Common” (Using Survey Findings) A survey means collecting information from people (e.g., households, students) to find patterns.
To decide which diseases are common, we can: Count how many people reported each disease. Compare the counts and identify the highest. Convert to percentages to make comparison fair.
