A blood-borne disease is a disease that can be spread through contamination by blood and other body fluids. Blood can contain pathogens of various types, chief among which are microorganisms, like bacteria and parasites, and non-living infectious agents such as viruses. Three blood-borne pathogens in particular, all viruses, are cited as of ...
Infectious diseases. Bloodstream infections (BSIs) are infections of blood caused by blood-borne pathogens. [1] The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis, which is characterized by severe inflammatory or immune responses of the ...
Frequency. ~200 cases per year (US) [7] Tularemia, also known as rabbit fever, is an infectious disease caused by the bacterium Francisella tularensis. [4] Symptoms may include fever, skin ulcers, and enlarged lymph nodes. [3] Occasionally, a form that results in pneumonia or a throat infection may occur.
Zoonosis. A zoonosis (/ zoʊˈɒnəsɪs, ˌzoʊəˈnoʊsɪs / ⓘ; [1] plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite, or prion) that can jump from a non-human vertebrate to a human. When humans infect non-humans, it is called reverse ...
Infectious disease. Viral hemorrhagic fevers (VHFs) are a diverse group of animal and human illnesses. VHFs may be caused by five distinct families of RNA viruses: the families Filoviridae, Flaviviridae, Rhabdoviridae, and several member families of the Bunyavirales order such as Arenaviridae, and Hantaviridae.
608,000 (2022) [5] Malaria is a mosquito-borne infectious disease that affects vertebrates and Anopheles mosquitoes. [6][7][3] Human malaria causes symptoms that typically include fever, fatigue, vomiting, and headaches. [1][8] In severe cases, it can cause jaundice, seizures, coma, or death. [1][9] Symptoms usually begin 10 to 15 days after ...
Viral disease. A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [1] Examples are the common cold, gastroenteritis and pneumonia. [2]
Human parvovirus B19 is a non-enveloped, icosahedral virus that contains a single-stranded linear DNA genome of approximately 5,600 base pairs in length. [10] B19V's nonenveloped viral particles are ~22 to 24 nm in diameter which are quite small compared to other parvoviruses. [3] The infectious particles may contain either positive or negative ...
