• PrEP is highly effective in preventing the sexual transmission of HIV.
• For PrEP to work well, it’s important to take the pills regularly.
• While PrEP can prevent HIV, it does not protect against other sexually transmitted infections.
This briefing paper provides an overview of pre-exposure prophylaxis (PrEP) for people planning, commissioning or providing HIV prevention activities in the UK. It does this by reviewing thirty key questions about PrEP and how it might be implemented in the UK.

The household transmission investigation is a case-ascertained prospective study of all identified household contacts of a laboratory confirmed 2019-nCoV infection (see 2.2 Study population). It is intended to provide rapid and early information on the clinical, epidemiological and virological chara...cteristics of 2019-nCoV.
There are three primary objectives of this household transmission study:
To better understand the extent of transmission within a household by estimating the secondary infection rate for household contacts at an individual level, and factors associated with any variation in the secondary infection risk.
To characterize secondary cases including the range of clinical presentation, risk factors for infection, and the extent and fraction of asymptomatic infections.
To characterize serologic response following confirmed 2019-nCoV infection (highly encouraged, but optional depending on laboratory capacity and resources)

There is no secret to our procedure: the daily scanning of the literature helps us to stay afloat in the never-ending waves of new publications about SARS-CoV-2 and COVID-19. Many papers discussed in the Top 10 will eventually make it into subsequent editions of COVID Reference.

Interim Guidance October 2022. This addendum addresses some of the methodological aspects of VE evaluations that have been learned during the past year, as well as those that have become relevant in the current epidemiological setting of the COVID-19 pandemic. For some of the COVID-19 vaccine method...ology issues there are still insufficient data to make a recommendation, in which case different options for approaching VE evaluations are presented.

This interim guidance is most useful for countries interested in monitoring relative circulations of influenza and SARS-CoV-2 viruses. The document provides practical information to maintain surveillance of influenza and monitor SARS-CoV-2 using e...xisting surveillance systems. It contains updated considerations for addressing disruptions in the influenza sentinel surveillance and extending to include COVID-19 wherever possible. Updated algorithms for testing of both influenza and SARS-CoV-2 for surveillance are also included. This document is an update of Operational considerations for COVID-19 surveillance using GISRS and GISRS for the upcoming influenza seasons during the COVID-19 pandemic

This checklist is an operational tool to help national authorities develop or revise national respiratory pathogen (inclusive of influenza and coronaviruses) pandemic preparedness plans.
The following protocol has been designed to investigate the First Few X cases (FFX) and their close contacts. It is envisioned that the FFX 2019-nCoV investigation will be conducted across several countries or sites with geographical and demographical diversity. Using a standardized protocol such a...s the protocol provided here, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of 2019-nCoV infection severity and transmissibility, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as 2019-nCoV
