Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we re...port an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.

In case of resistance to rifampicin, fluoroquinolones become the preferred category of second-line drugs. Unfortunately, quinolone-resistant strains of Mycobacterium leprae have also been reported in several countries, probably due to the extensive use of quinolones for treating several types of inf...ections. Clofazimine resistance is still rare but this antimicrobial cannot be given alone

These interim IPC recommendations for health settings have been developed through the contributions of many individuals and institutions, such as the Centers for Disease Control-Kenya; ITECH; US Agency for International Development (USAID) Medicines, Technologies, and Pharmaceu...tical Services (MTaPS) Program; and WHO that are committed to ensuring that the transmission of COVID-19 to HCWs and the public within the health care setting is limited. The Ministry of Health (MOH) through the Directorate of Health Standards Quality Assurance and Regulations wishes to thank all the contributing authors led by the sub-committee on case management and IPC for the COVID-19 response for their expertise and time given to writing these guidelines.

Monkeypox is an emerging viral zoonosis with symptoms similar to those observed in smallpox patients, although less severe. Since the global eradication of smallpox in 1980, monkeypox has emerged as the most important orthopoxvirus in humans. The Advisory Committee on Variola Virus Research (ACVVR) ...which meets annually to oversee smallpox research has highlighted the importance of diagnostics that could distinguish between variola and other strains of orthopoxviruses, including monkeypox virus. The ACVVR encourages the positive effects of current smallpox research on all orthopoxviruses, specifically monkeypox, such as the development of diagnostic tools.

Lesotho’s predominantly rural population faces significant health challenges within a setting of inadequate human resources for health. It is essential that nurses and nurse-midwives, who together make up the largest health workforce in the country, be adequately prepared to address Lesotho’s He...alth Priorities according to the Poverty Reduction Strategy Paper (PRSP) in the settings where they work. Under the HRAA project, Jhpiego conducted a task analysis study to obtain data on job duties or tasks performed by these cadres, as well as information about how often the tasks are performed, if and where tasks were learned, and the self-perceived level of competence in performing the tasks.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

Rabies is a fatal viral disease, but is preventable in humans. The rabies virus is transmitted to humans through virus-laden saliva from a rabid animal, mostly dogs. The virus is shed in the saliva of an infected animal and can be introduced into another body through bites, scratches and any other ...wounds that transect the skin. Contact of the infected saliva with mucous membranes is also thought to be a possible route of infection, whereas contact of infected saliva with intact skin is not considered an exposure. Rabies is preventable through pre-exposure prophylaxis (PrEP) for individuals at high and continual risk, and post-exposure prophylaxis (PEP).

The practical guidance in the operational handbook aims to inform the development or revision of national policies and related implementation guidance on the management of TB in children and adolescents under programmatic circumstances and at different levels of the health system. The operational ha...ndbook can also help countries adequately plan for the uptake of interventions to better address the specific needs of children and adolescents with or at risk of TB. It can contribute to national efforts to build capacity among national and subnational programme managers and among health workers at all levels of the health care system.

A total of 18 laboratories from 13 countries participated in the four rounds of EQA: 10 laboratories from eight African endemic countries, four of which participated in all four rounds and three in three rounds. The overall results showed that the median performance of these laboratories improved ov...er the four rounds. However, the proportion of laboratories reporting false–positive cases remains high and indicates a problem of specificity probably due to contamination. The proportion of laboratories reporting both false–positive and false–negative results raises the issue of the quality of the data reported by WHO in Africa as well as the results of the studies carried out in these different laboratories in various countries.
