9 March 2022, Timely and accurate diagnostic testing for SARS-CoV-2 is an essential part of a comprehensive COVID-19 response strategy. Ag-RDTs can be performed by individuals in which they collect their own specimen, perform a simple rapid test and interpret their test result themselves at a time a...nd place of their choosing, termed COVID-19 self-testing. This interim guidance provides a new recommendation that COVID-19 self-testing, using SARS-CoV-2 Ag-RDTs, should be offered as part of SARS-CoV-2 testing services. It also includes implementation considerations that can guide decisions on whether, and how, to adopt self-testing in different contexts, including the populations being prioritized; the disease prevalence in that population; and the impact on accessibility of testing, health care services and result reporting.

Hendra virus (HeV) continues to pose a serious public health concern as spillover events occur sporadically. Terminally ill horses can exhibit a range of clinical signs including frothy nasal discharge, ataxia or forebrain signs. Early signs, if detected, can include depression, inappetence, colic o...r mild respiratory signs. All unvaccinated ill horses in areas where flying foxes exist, may potentially be infected with HeV, posing a significant risk to the veterinary community. Equivac® HeV vaccine has been fully registered in Australia since 2015 (and under an Australian Pesticides and Veterinary Medicines Authority special permit since 2012) for immunization of horses against HeV and is the most effective and direct solution to prevent disease transmission to horses and protect humans. No HeV vaccinated horse has tested positive for HeV infection. There is no registered vaccine to prevent, or therapeutics to treat, HeV infection in humans. Previous equine HeV outbreaks tended to cluster in winter overlapping with the foaling season (August to December), when veterinarians and horse owners have frequent close contact with horses and their bodily fluids, increasing the chance of zoonotic disease transmission. The most southerly case was detected in 2019 in the Upper Hunter region in New South Wales, which is Australia's Thoroughbred horse breeding capital. Future spillover events are predicted to move further south and inland in Queensland and New South Wales, aligning with the moving distribution of the main reservoir hosts. Here we (1) review HeV epidemiology and climate change predicted infection dynamics, (2) present a biosecurity protocol for veterinary clinics and hospitals to adopt, and (3) describe diagnostic tests currently available and those under development. Major knowledge and research gaps have been identified, including evaluation of vaccine efficacy in foals to assess current vaccination protocol recommendations.

In the light of the transmissibility of coronaviruses, and the global experience with MERS-CoV (ongoing) and SARS in 2003 which were also caused by coronaviruses, South African authorities have compiled this guideline document to support surveillance, case finding, diagnosis, management and public h...ealth responses to cases under investigation.
*Please note*
The interim guidelines are based on what is currently known about the Coronavirus Disease 2019 (COVID-19). The National Department of Health (NDOH) and National Institute for Communicable Diseases will update these interim guidelines as needed and as additional information becomes available.

Any individual that meets the suspected case definition of monkeypox should be offered testing in appropriately equipped laboratories by staff trained in the relevant technical and safety procedures. Confirmation of monkeypox virus infection is based on nucleic acid amplification testing (NAAT), usi...ng real-time or conventional polymerase chain reaction (PCR), for detection of unique sequences of viral DNA. PCR can be used alone, or in combination with sequencing. The recommended specimen type for laboratory confirmation of monkeypox is skin lesion material, including swabs of lesion surface and/or exudate, roofs from more than one lesion, or lesion crusts.

The World Health Organization Global TB Report provides a comprehensive and up-to-date assessment of the TB epidemic, and progress in the response, at global, regional and country levels.
The 2022 edition features data on disease trends and the response to the epidemic from 215 countries and area...s, including all 194 World Health Organization (WHO) Member States. It provides a comprehensive and up-to-date assessment of the TB epidemic, progress in the response at global, regional and country levels, as well as on the impact of the COVID-19 pandemic on TB services.
TB remains one of the top infectious killers in the world. This year’s report presents data on an increase in the number of people falling ill with TB and drug resistant TB for the first time in many years. Increases were also reported on the number of TB deaths, highlighting the severe impact of the COVID-19 pandemic and other crises on the TB response that has reversed years of progress. It also presents the status of progress towards targets set at the first-ever United Nations General Assembly high-level meeting on TB in 2018 as well as the targets of the WHO End TB Strategy and the Sustainable Development Goals.

The meeting was held from 26 to 27 March 2018 to review and discuss the following topics:
Advances and challenges in the use of fTLC, and new approaches to detecting mycolactone using monoclonal antibodies (mAbs).
The status of development of rapid diagnostic tests (RDTs) targeting the MUL..._3720 protein.
The role of PCR as a reference test, and hurdles in providing a confirmatory diagnosis and in establishing a quality assurance programme.
New molecular tools with potential for implementation at a level lower than in the national or regional reference laboratory, such as loop-mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA).
The need to harmonize and standardize methods for collection and preparation of specimens, so samples can be referred for diagnosis and stored for evaluation of new diagnostic tests in optimal conditions.
Barriers to accessing early diagnosis and treatment, including coordination at the programme level, and lack of adequate diagnostic tools.
Defining target product profiles (TPPs) to guide the development of new diagnostic tools that can be applied at different levels of the health system. Participants agreed that two TPPs would be developed to address the current gaps: (i) a rapid test for BU diagnosis at the primary health-care level; and (ii) a test for diagnosis of BU that can also assist in treatment monitoring and differential diagnosis at the district hospital or reference centre.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.
