destruction of a host cell
Anything that causes disease is considered to be pathogenic. This includes viruses and bacteria. People who come in contact with certain of these organisms may become very ill.
Viruses are not considered living organisms but can cause disease. Prions that cause Bovine Spongiform Encephalopathy (Mad Cow disease, aka vCJD- variant Creutzfeld-Jakob disease when in humans) are not living organisms as they are just misfolded protein particles.
Living organisms that cause disease are known as pathogens. These can include bacteria, viruses, fungi, parasites, and prions. Pathogens can enter the body through various means and lead to infections that result in illness.
Infectious diseases involve a causative organism, from groups such as bacteria, viruses, fungi, and such. Noninfectious diseases involve causes other than specific infectious organisms.
bacteria, and other infectious agents are called pathogens. This also includes viruses, even though they technically aren't organisms

Fungi
The flu viruses cause the infectious respiratory disease known as influenza.
Yes, viruses are the smallest known pathogens that can cause disease in humans, as they are much smaller than bacteria and other microorganisms. Viruses rely on host cells to replicate and can infect a wide range of organisms, including humans, animals, plants, and even bacteria.
Diseases are often caused by viruses and bacteria or genetic factors.
Skin diseases can be caused by viruses, fungi, bacteria, or parasites.
