Here are some common ways infectious diseases spread. Be aware so you know how to avoid disease transmission.
Infectious diseases can be caused by organisms such as viruses, bacteria fungi or parasites. Infectious diseases may be passed via direct contact from person to person, from animal to person or from a mother to the unborn child. They may also be passed by
indirect contact such as touching an object like a doorknob that has germs on it. Diseases can also be spread via
Mother to unborn child
Contaminated Objects or Surfaces
Diseases can be passed from one person to another by indirect contact. For example, any object has the potential to be a carrier of an infectious agent. Dirty clothes and linen, common surfaces such as doorknobs, utensils and unsterilised hospital equipment are some examples of breeding grounds for bacteria and viruses that can live on surfaces for different lengths of time depending on the nature of the germ and environmental conditions. This can happen when an infected person coughs or sneezes and the disease-causing organisms land on the object.
Some germs can spread via multiple routes. For example, the common cold virus may spread via person-to-person transmission if someone coughs or sneezes next to you and the virus is inhaled directly. it may also spread via indirect contact if the virus lands on a doorknob or table and later another person touches that surface and gets the virus into their mouth, nose, or eyes by touching their face.
