Hospital Acquired Infections (HAIs), also commonly referred to as Nosocomial infections, present a significant problem to hospitals around the world. The problem is more pronounced in African hospitals due to the lack of thorough and efficient sanitation and hygiene practices. They present a substantial danger to infants in neo-natal care who do not have well developed immune systems. Hospital acquired infections also pose a significant economic and social problem in urban areas. Although a wide range of pathogens can cause nosocomial infections, bacteria is responsible for a larger number of infections. With this in mind, a safe, effective and cost-effective solution is essential to minimize the occurrence of nosocomial infections. The strategy employed will be to try to reduce bacterial colonies in hospitals to prevent infection by bacteria. Natural fibres have been documented to exhibit anti-microbial action and they are also very cheap. The creation of a mat using such fibres that can be used in hospitals to reduce bacterial growth will form the basis of the solution.
