Give three suggestions of how you can ensure viruses are not introduced to the computer system from an external source?
The organs of the immune system fight viruses and bacteria.
Adventitious viruses are viruses that are unintentionally introduced into a biological system, such as cell cultures or plant tissues, often through contamination during the production or handling processes. These viruses can interfere with experiments or production, potentially affecting the purity and quality of biological products. Their presence is a concern in biotechnology and pharmaceutical industries, as they can compromise research results and product safety. Monitoring and controlling for adventitious viruses is a critical aspect of good manufacturing practices.
Deactivated viruses, also known as inactivated or killed viruses, are used in vaccines to stimulate an immune response without causing disease. When introduced into the body, these viruses cannot replicate but still elicit an immune response, prompting the production of antibodies. This prepares the immune system to recognize and fight the actual virus if encountered in the future. Examples of vaccines using deactivated viruses include the polio vaccine and the hepatitis A vaccine.
The substance introduced into the body to stimulate the production of chemicals that destroy specific disease-causing viruses and organisms is called a vaccine. Vaccines work by exposing the immune system to a harmless component of the pathogen, prompting the body to generate an immune response and "memory" cells. This prepares the immune system to recognize and combat the actual pathogen if encountered in the future, thereby providing immunity.
