This document updates recommendations for HIV testing by laboratories in the United States and offers approaches for reporting test results to persons ordering HIV tests and to public health authorities. The recommended algorithm is a sequence of tests used in combination to improve the accuracy of ...the laboratory diagnosis of HIV based on testing of serum or plasma specimens. The updated recommendations also include tests for HIV antigens and HIV nucleic acid because studies from populations at high risk for HIV demonstrate that antibody testing alone might miss a considerable percentage of HIV infections detectable by virologic tests

Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

Los coronavirus son un grupo de virus ARN altamente diversos de la familia Coronaviridae que se dividen en
4 géneros: alfa, beta, gamma y delta, y que causan enfermedades de leves a graves en humanos y animales
(1-3). Existen coronavirus humanos endémicos como los alfacoronavirus 229E y NL63 y l...os betacoronavirus
OC43 y HKU1 que pueden causar enfermedades de tipo influenza o neumonía en humanos. Sin embargo,
tres betacoronavirus zoonóticos que pueden causar enfermedad severa en humanos han emergido: el
coronavirus del Síndrome respiratorio agudo grave (SARS-CoV), el coronavirus del Síndrome respiratorio de
Oriente Medio (MERS-CoV) y el virus de COVID-19 (SARS-CoV-2).
