Integrated HIV Behavioral and Serologic Surveillance
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)

Epidemiology, Distribution, Surveillance and Control
This algorithm is addressed to laboratories
with established capacity(molecular, antigenic and/orserological) to detect dengue (DENV), Zika (ZIKV), and chikungunya(CHIKV) as part of the differential diagnosis for arborviruses. A BSL2 containment level is required to handle suspected samples.

This publication aims to provide updated guidance on the specific use of yellow fever laboratory assays in the context of surveillance to be used across the Global Yellow Fever Laboratory Network for disease ...x">surveillance. In the recent years, new commercial assays became available and are now recommended for use by WHO and this publication will support national program on the use of compound laboratory assays as per the most recent recommended testing algorithms. This piece is aligned with the elimination effort set in the comprehensive global strategy to eliminate yellow fever epidemics (EYE) strategy 2017-2026 and where its advisory laboratory technical working group actively contributed to its development. The target audiences are policy-makers and health workers.

This is a case-ascertained prospective investigation of all identified health care contacts working in a health care facility in which a laboratory confirmed 2019-nCoV infected patient (see 2.2 Study population) receives care. Note that this study can be done in health care facilities at all 3 level...s of a health system – not just in hospitals. It is intended to provide epidemiological and serologic information which will inform the identification of risk factors 2019-nCoV infection among health care workers.
There are three primary objectives of this investigation among health care workers in a health care setting where a 2019-nCoV infected patient is being cared for:
To better understand the extent of human-to-human transmission among health care workers, by estimating the secondary infection rate1 for health care worker contacts at an individual level.
To characterize the range of clinical presentation of infection and the risk factors for infection among health care workers.
To evaluate effectiveness of infection prevention and control measures among health care workers
To evaluate effectiveness of infection prevention and control programmes at health facility and national level

Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars.... Humans usually acquire
leptospirosis through direct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.

This WHO laboratory manual provides the most up to date methods and procedures for the laboratory identification of yellow fever virus infection in humans. It provides guidance on the establishment and maintenance of an effective laboratory providing routine ...x">surveillance testing for yellow fever, which operates within the WHO coordinated Global Yellow Fever Laboratory Network (GYFLaN) capable of providing confirmation of yellow fever infection reliably and timely. This second edition supersedes the first edition of the 2004 WHO manual for the monitoring of yellow fever virus infection.
