Two test methods on dexamethasone tablets and injections
The growing understanding of how sequence information can contribute to improved public health is driving global investments in sequencing facilities and programmes. The falling cost and complexity of generating GSD provides opportunities for expanding sequencing capacity; however, challenges to wid...espread implementation remain. This document provides policy-makers and stakeholders with guidance on how to maximize the public health benefit of SARS-CoV-2 genomic sequencing activities in the short and long term as the pandemic continues to unfold. Practical considerations for the implementation of a virus genomic sequencing programme and an overview of the public health objectives of genomic sequencing are covered. This guidance focuses on SARS-CoV-2 but is applicable to other pathogens of public health concern.

El desarrollo de inmunidad a un patógeno por infección natural es un proceso de varias etapas que suele producirse a lo largo de una o dos semanas. El organismo responde a una infección vírica de forma inmediata a través de una respuesta innata no específ...ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

Four (04) new EVD alerts were reported from Rubkona, Nimule, and juba during week 45 (ending 13 November 2022) but only one sample was collected for laboratory confirmation which tested negative. The other three were discarded as they did not meet EVD case definition.
The document outlines the 2017 cholera outbreak in Zambia, mainly in Lusaka, due to poor sanitation and unsafe water. By December, 493 cases were reported, with risks increasing due to the rainy season. The Zambia Red Cross Society (ZRCS), in collaboration with the Ministry of Health, WHO, and UNICE...F, responded by setting up treatment centers, supplying clean water and chlorine, and conducting hygiene education. 1,500 volunteers were mobilized to support 70,000 people directly. The IFRC allocated CHF 222,351 to control the outbreak, but challenges like limited funding and poor infrastructure remained.
