Infective

Infective refers to the ability of a pathogen to establish an infection. The term is often used in the context of diseases and conditions caused by bacteria, viruses, fungi, and other microorganisms.

Definition

An Infective agent or substance is capable of producing an infection. This can be a bacterium, virus, or other type of microorganism, which can cause disease in its host. The host can be an animal, a plant, or even another microorganism.

Types of Infective Agents

There are several types of infective agents, including:

• Bacteria - These are single-celled organisms that can cause diseases such as pneumonia, strep throat, and urinary tract infections.
• Viruses - These are smaller than bacteria and can cause diseases such as the flu, colds, and COVID-19.
• Fungi - These include molds and yeasts, which can cause infections like athlete's foot and yeast infections.
• Parasites - These are organisms that live on or in a host organism and get their food from or at the expense of their host. Parasites can cause diseases such as malaria and toxoplasmosis.

Infective Diseases

Infective diseases are caused by the invasion of the body by pathogenic microorganisms. Some examples of infective diseases include:

• Influenza - A viral infection that attacks the respiratory system.
• Tuberculosis - A bacterial infection that primarily affects the lungs.
• HIV/AIDS - A viral infection that attacks the immune system.
• Malaria - A parasitic infection that is spread by mosquitoes.

Prevention and Treatment

Prevention and treatment of infective diseases often involve a combination of vaccination, hygiene practices, and medication. For example, bacterial infections can often be treated with antibiotics, while viral infections may be prevented through vaccination.
