Weekly epidemiological update on COVID-19, 28 September 2022
Zika and dengue viruses remain significant public health threats. These viruses share the same Aedes (Stegomyia) mosquito vectors and geographic distributions but infections cannot be readily distinguished clinically and need to be differentiated from each other, and from other circulating arboviral... and non-arboviral pathogens, using laboratory tests. This document provides guidance on current testing strategies for Zika and dengue virus infections with updates to the previous interim guidance for laboratory testing for ZIKV, addressing pregnant and non-pregnant patients respectively, and incorporates current guidance for dengue virus diagnostic testing. The choice of laboratory assays and interpretation of test results require careful consideration of epidemiology, patient history, and limitations of existing diagnostic tests.
This interim guidance is for use by staff of laboratories testing for Zika and dengue virus infections and for clinical practitioners and public health professionals providing clinical management or surveillance.

Nested case-control study of health workers exposed to confirmed COVID-19 patients.
Similar objectives to the cohort study but case-control studies may be cheaper and provide robust evidence to characterize and assess the risk factors for SARS-CoV-2 infection in health workers exposed to COVID-19 p...atients.
Health workers with confirmed COVID-19 will be recruited as cases and other health workers in the same health care setting without infection will be recruited as controls (incidence density sampling).
Secondary objectives are similar to the cohort study.

Patients with retreatment tuberculosis (TB) represent those
who have been treated previously for onemonth ormorewith
anti-TB drugs and who have been diagnosed once again with
the disease.These patientsmainly include relapses, treatment
after failure, or loss to follow-up on a first-line treatmen...t
regimen [1]. The number of these patients is not negligible.
In 2014, of the 6.3 million TB cases that were notified
by National TB Programmes (NTPs) to the World Health
Organization (WHO), approximately 700,000 patients were
already previously treated

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)

Stenotrophomonas maltophiliais a nonfermenting Gram-negative rod that is ubiquitous in nature (predominantly occurring in aquatic environments and on plants). Biochemically, it iscatalase positive and oxidase negative, and it produces acid frommaltose (hence the name“maltophilia”). Due to it...s chargedcell wall surface and biofilm production, it may attach to and survive on abiotic surfaces in clinical settings (eg, central venouscatheters, disinfectant and hand-washing solutions, solutions for hemodialysis, endoscopes, inspiration/expiration circuits of ventilators, nebulizers, tap water, and showerheads).

Schistosomiasis is a neglected tropical disease of global medical and veterinary importance. As efforts to eliminate schistosomiasis as a public health problem and interrupt transmission gather momentum, the potential zoonotic risk posed by livestock Schistosoma species via viable hybridisation in s...ub-Saharan Africa have been largely overlooked. We aimed to investigate the prevalence, distribution, and multi-host, multiparasite transmission cycle of Haematobium group schistosomiasis in Senegal, West Africa.
