La fiebre amarilla es una enfermedad causada por el virus Virus Viruses are infectious, obligate intracellular parasites composed of a nucleic acid core surrounded by a protein capsid. Viruses can be either naked (non-enveloped) or enveloped. The classification of viruses is complex and based on many factors, including type and structure of the nucleoid and capsid, the presence of an envelope, the replication cycle, and the host range.

Virology de ácido ribonucleico (ARN) monocatenario de sentido positivo del género Flavivirus Flavivirus A genus of flaviviridae containing several subgroups and many species. Most are arboviruses transmitted by mosquitoes or ticks. The type species is yellow fever virus. Tick-borne Encephalitis Virus. Los LOS Neisseria seres humanos y los LOS Neisseria primates sirven de reservorios, y la transmisión se produce por la picadura de un mosquito Aedes hembra infectado. La mayoría de los LOS Neisseria pacientes presentan fiebre y síntomas similares a los LOS Neisseria de la gripe. La enfermedad severa puede causar una disfunción multiorgánica que provoca ictericia, disfunción renal, hemorragia, shock Shock Shock is a life-threatening condition associated with impaired circulation that results in tissue hypoxia. The different types of shock are based on the underlying cause: distributive (↑ cardiac output (CO), ↓ systemic vascular resistance (SVR)), cardiogenic (↓ CO, ↑ SVR), hypovolemic (↓ CO, ↑ SVR), obstructive (↓ CO), and mixed. Types of Shock y potencialmente la muerte. El diagnóstico puede confirmarse con serología y reacción en EN Erythema nodosum is an immune-mediated panniculitis (inflammation of the subcutaneous fat) caused by a type IV (delayed-type) hypersensitivity reaction. It commonly manifests in young women as tender, erythematous nodules on the shins. Erythema Nodosum cadena de polimerasa ( PCR PCR Polymerase chain reaction (PCR) is a technique that amplifies DNA fragments exponentially for analysis. The process is highly specific, allowing for the targeting of specific genomic sequences, even with minuscule sample amounts. The PCR cycles multiple times through 3 phases: denaturation of the template DNA, annealing of a specific primer to the individual DNA strands, and synthesis/elongation of new DNA molecules. Polymerase Chain Reaction (PCR), por sus siglas en EN Erythema nodosum is an immune-mediated panniculitis (inflammation of the subcutaneous fat) caused by a type IV (delayed-type) hypersensitivity reaction. It commonly manifests in young women as tender, erythematous nodules on the shins. Erythema Nodosum inglés). No hay tratamiento antiviral Antiviral Antivirals for Hepatitis B, por lo que el tratamiento es de soporte. La prevención incluye evitar los LOS Neisseria mosquitos y vacunación.

Identificación de los virus ARN:
Los virus pueden clasificarse de muchas maneras. Sin embargo, la mayoría de los virus tienen un genoma formado por ácido desoxirribonucleico (ADN) o ARN. Los virus con genoma ARN pueden caracterizarse además por tener ARN monocatenario o bicatenario. Los virus “envueltos” están cubiertos por una fina capa de membrana celular (normalmente tomada de la célula huésped). Si la capa está ausente, los virus se denominan “desnudos”. Los virus con genomas monocatenarios son de “sentido positivo” si el genoma se emplea directamente como ARN mensajero (ARNm), que se traduce en proteínas. Los virus monocatenarios de “sentido negativo” emplean la ARN polimerasa dependiente de ARN, una enzima viral, para transcribir su genoma en ARN mensajero.

Virology de la hepatitis C Hepatitis C Hepatitis C is an infection of the liver caused by the hepatitis C virus (HCV). The infection can be transmitted through infectious blood or body fluids and may be transmitted during childbirth or through IV drug use or sexual intercourse.
