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]
Other viral diseases. Many of the most common illnesses people get are caused by viruses, and these can have some surprising effects. Herpes simplex virus might cause Alzheimer’s disease
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 ...
There are some viruses most people are at least aware of, like RSV and the flu. But then there are some that are common but most people have never heard of before. Human metapneumovirus (HMPV ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
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 .
