Transmission electron micrograph of the Sin Nombre virus, the virus responsible for the outbreak. The spherical particles are virus bodies (virions). The 1993 Four Corners hantavirus outbreak was a disease outbreak caused by a hantavirus that occurred in the Four Corners region of the US states in Arizona, Colorado, and New Mexico.
Several birthmark types are part of the group of skin lesions known as nevi or naevi, which is Latin for "birthmarks". Birthmarks occur as a result of a localized imbalance in factors controlling the development and migration of skin cells. In addition, it is known that vascular birthmarks are not hereditary. [2] [3]
Virus-related cutaneous conditions are caused by two main groups of viruses–DNA and RNA types–both of which are obligatory intracellular parasites. [69] [73] Alphavirus infection; Asymmetric periflexural exanthem of childhood (unilateral laterothoracic exanthem) B virus infection; Boston exanthem disease; Bovine papular stomatitis; Bowenoid ...
SARS‑CoV‑2 is a strain of the species Betacoronavirus pandemicum (SARSr-CoV), as is SARS-CoV-1, the virus that caused the 2002–2004 SARS outbreak. [ 2 ] [ 17 ] There are animal-borne coronavirus strains more closely related to SARS-CoV-2, the most closely known relative being the BANAL-52 bat coronavirus.
Pandemics timeline death tolls. This is a list of the largest known epidemics and pandemics caused by an infectious disease in humans. Widespread non-communicable diseases such as cardiovascular disease and cancer are not included.
What is Marburg virus? It is a hemorrhagic fever virus from the same family as the virus that causes Ebola. The virus can be transmitted by exposure to mines or caves inhabited by Rousettus bat ...
Scanning electron micrograph of SARS virions. Severe acute respiratory syndrome (SARS) is the disease caused by SARS-CoV-1. It causes an often severe illness and is marked initially by systemic symptoms of muscle pain, headache, and fever, followed in 2–14 days by the onset of respiratory symptoms, [13] mainly cough, dyspnea, and pneumonia.
The name is derived from Latin parvum, meaning small, reflecting the fact that B19 ranks among the smallest DNA viruses. B19 virus is most known for causing disease in the pediatric population; however, it can also affect adults. It is the classic cause of the childhood rash called fifth disease or erythema infectiosum, or "slapped face syndrome".
