Prevention and Treatment
The infectious agents enter an individual body through the skin, injuries, inhalation of airborne pathogens, eating and drinking contaminated food and water, and parasites. The prevention of infectious diseases can be done by maintaining proper hygiene and clean environment, following lifestyle, etc. Immunization can also help an individual to resist many diseases. After the diagnosis of a specific illness, it becomes easier for a practitioner to choose the appropriate treatment. Most of the illness can be treated with the help of a common practitioner but some diseases where the individual does not respond to the treatment are difficult to treat. New approaches for treating drug-resistant pathogens are in developing stage to find new drugs.
