An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
Medications are usually not needed as hand, foot, and mouth disease is a viral disease that typically resolves on its own. Under research [15] [16] Sin Nombre virus: Hantavirus Pulmonary Syndrome (HPS) No Heartland virus: Heartland virus disease No Helicobacter pylori: Helicobacter pylori infection No Escherichia coliO157:H7, O111 and O104:H4
An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. [2] Hosts can fight infections using their immune systems.
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
I. Communicable, maternal, neonatal, and nutritional disorders: Respiratory infections and tuberculosis: 6.85: 19.49%: Enteric infections: 3.31 Sexually transmitted infections: 1.88 Tropical diseases and malaria: 1.37 Other infectious diseases: 1.57 Maternal and neonatal disorders: 4.00 Nutritional deficiencies: 0.52 II.

In biology, a pathogen (Greek: πάθος, pathos "suffering", "passion" and -γενής, -genēs "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. [1] The term pathogen came into use in the 1880s.
For example, a disease with a known low asymptomatic rate may lead to increased surveillance of symptomatic cases, whereas a higher asymptomatic rate could lead to more aggressive methods such as travel bans and compulsory quarantines, since the number of infectious, asymptomatic cases would be unknown.
The concept of linear transition from infectious diseases to other conditions referred to as degenerative or non-communicable, was based on a false dichotomy as common microorganisms have now been confirmed as causal agents in several conditions recorded as the underlying cause of many deaths. A revised transition model might focus more on ...
