Virions of some of the most common human viruses with their relative size. Nucleic acids are not to scale. SARS stands for SARS-CoV-1 or COVID-19, variola viruses for smallpox. Basic structural characteristics, such as genome type, virion shape and replication site, generally share the same features among virus species within the same family.
Contrary to common belief, harmful viruses may be in the minority, compared to benign viruses in the human body. It is much harder to identify viruses than it is to identify bacteria, therefore the understanding of benign viruses in the human body is very rudimentary. [ 2 ]

Widespread non-communicable diseases such as cardiovascular disease and cancer are not included. An epidemic is the rapid spread of disease to a large number of people in a given population within a short period of time; in meningococcal infections , an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered ...
A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans. The human physiological defense against common pathogens (such as Pneumocystis ) is mainly the responsibility of the immune system with help by some of the body's normal microbiota .
