Our bodies have defence mechanisms that can destroy infection and restore health. Task 1 Submission Date – 23/09/13 and 03/02/14 This task relates to achievement of assessment

feral pigeon (Columba livia). Although there are few reports of disease transmission between pigeons and humans‚ their close interaction with humans and ability to carry zoonotic pathogens make them a public health risk. In fact‚ these birds are present at very high densities (2‚000 individuals per km2) and can cover a maximum distance of 5.29 km (Dickx et al.‚ 2010). This may result in the increase risk of pathogen transmission among other birds and potentially to humans. Studies have shown that

A classic characteristic of human parasitic and bacterial agents is the evolution of routes for transmission pathogens to susceptible hosts. The environment plays a critical role in transmission to humans‚ with many environmental materials serving as vehicles. Microbial contaminants may be transmitted directly‚ through hand-to-hand contact‚ or indirectly‚ via food or other inanimate objects like fomites. (Rote‚ et al.‚ 2010) According to Umeh‚ et al (2007)‚ Contamination of objects by pathogenic

important control practice. It is essential because personal contact is the primary mode of MRSA transmission. Therefore good hand washing technique is vital to ensure that the decontamination is effective‚ as no soap will be effective if the technique is poor. Rayner (2003) affirms this by stating that appropriate hand washing effectively removes transient organisms‚ which prevents MRSA transmission. It is clear that there are many advantages and disadvantages to the process of hand hygiene

Newly emerged impregnated females will crawl onto the uninfected person. The mite will hold onto the skin using suckers attached to the two most anterior pairs of legs. They will then burrow into the skin. Transmission may also occur via fomites (e.g.‚ bedding or clothing). Sarcoptes scabei undergoes four stages in its life cycle; egg‚ larva‚ nymph and adult. Sarcoptic mites form definite burrows under the skin in which females deposit eggs. Females deposit eggs at 2 to 3
