There are numerous health problems in shanty towns. Firstly, because the sites are illegal the government does not provide piped water. As a result, drinking and bathing water are usually dirty and this causes diseases such as dysentery, typhoid and hepatitis, as well as skin and eye diseases. Secondly, houses are often overcrowded and have poor air circulation. This makes it easier to catch diseases like flu, TB and diphtheria where infection enters through the throat. Thirdly, there are no drains, sewers or rubbish collection services. The resulting pools of stagnant water and heaps of household waste attract rats and insects, which can pass on diseases.
Problem-Solution Patterns A problem-solution pattern divides information into two main sections, one that describes a problem and one that describes a solution. This pattern is typically used in persuasive writing, where the writer's general purpose is to convince the reader to support a certain course of action. The pattern is designed to compel the reader to make some kind of change in opinion or behavior by establishing that a problem exists, then providing a solution. In the problem section, the writer identifies different aspects of the problem being discussed and offers evidence of these problems. In the solution section, the writer identifies a potential solution and supports the effectiveness of this solution over others.
