breathing‚ eating‚ drinking‚ cuts‚ wounds or medical procedures like catheters or injections. The five main routes are: * Contact – * Direct transmission involves direct body surface-to-body surface contact and physical transfer of microorganisms from an infected or colonised person to a susceptible host. This may occur between patient and carer during patient care that involves direct personal contact‚ or between any two persons (patients‚ carers‚ others) in the health care setting.

Common Causes of Infection Transmission What is Infection? Microbes can lead to an infection only if they have capacity to multiple. Our bodies get infections from pathogenic microorganisms that cannot observe by naked eye such as • Bacteria. These one-cell organisms are accountable for diseases‚ such as urinary tract infections. • Viruses. Is an acellular agent smaller than bacteria consisting mainly of genetic material‚ that can be active in a close environments ranging from the common cold

Microbiology is the study of living organisms that are too small to be clearly seen by the unaided eye. The science of Microbiology dates back only to 200 years‚ yet the recent discovery of Mycobacterium tuberculosis DNA in 3000 year old Egyptian mummy reminds us that microbes have been around for much longer. Infact‚ Bacterial ancestors were the first living things to appear on Earth. The First observations: One of the most important discoveries in the history of Microbiology occurred in 1665

Entrance barriers (high): it is hard to entry this industry‚ the top three carriers already dominate 86% of the industry. And it need a large scale of capital to entry this industry. For instance‚ with the development of business‚ global express demand increases. Airborne Express international strategy can

Airborne diseases refers to any diseases which are caused by pathogens and transmitted through the air. These viruses and bacteria can be spread through coughing‚ sneezing‚ laughing or through close personal contact. These pathogens ride on either dust particles or small respiratory droplets and can stay suspended in air and or are capable of traveling distances on air currents.[1] Often‚ airborne pathogens or allergens cause inflammation in the nose‚ throat‚ sinuses and the lungs. This is caused
