Contacts between infected and non - infected persons should be controlled by monitoring contacts for 5 days from the date of exposure. The environment around cholera victims should be controlled. This can be done through disinfection of clothes and beddings used by cholera patients, and terminal cleaning of the rooms occupied by cholera patients (Department of Health, Victoria, Australia, 2007). The rate at which it grows is dependent on the amount of available nutrients. If nutrients are not available, the fungus enters the log stage. In this stage, it degrades the keratin found in the stratum corneum forming the appropriate amino acids that provide nutrients for reproduction and growth. Once nutrients are available, it enters the stationary stage whereby degradation of keratin slows down. The trichophyton uses its enzymes, proteases in particular to degrade keratin cells and produce nutrients for its survival. To prevent and contain the spread of trichophyton, it is good to ensure that there is enough aeration to the feet, wearing of socks that absorb sweat away from the skin, avoid wearing of wet socks or sharing socks, avoid sharing of towels, drying the feet thoroughly after washing them, washing the feet habitually with water and soap and changing socks and shoes regularly (Department of Biology, Davidson College, 2007). Malaria is transmitted when a female anopheles mosquito takes in the plasmodium gametocytes from an infected person. After 8 – 35 days, the plasmodium develops into its infective form which is transmitted to another individual through a bite of the infected anopheles mosquito. The life cycle is divided into 4 stages that are; growth, development, transmission and reproduction. It is complex as it has varying phases, time length
