Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

Situation analysis
Description of the disaster
An Ebola epidemic that started in March 2014 in Guinea has relentlessly continued to claim lives and to spread to other countries in West Africa. The current Ebola outbreak is the largest in history and the first to affect multiple countries simu...ltaneously. There have been over 24 000 reported confirmed, probable, and suspected cases of EVD in Guinea, Liberia and Sierra Leone (table 1), with almost 10 000 reported deaths (outcomes for many cases are unknown). A total of 58 new confirmed cases were reported in Guinea, 0 in Liberia, and 58 in Sierra Leone in the 7 days to 8 March (4 days to 5 March for Liberia). Many experts believe that the official numbers substantially understate the size of the outbreak because of families' widespread reluctance to report cases. Because of the fluidity of movement of people between West Africa and several countries in the East African countries, especially Kenya and Ethiopia (who in turn have extensive interaction with other countries in the region in terms of human movement), the risk of an outbreak of Ebola in East Africa is as eminent as in any of the countries bordering the affected countries. The IFRC regional office intends to support National Societies to raise their Ebola preparedness and response capacity through training, technical support in planning and implementation of Ebola related activities, and coordination both within and outside the movement.

The handbook is the first comprehensive collection of practical tips for journalists on how to report on GBV in the context of Syria crisis, building upon internationally recognised ethical principles. It gives an overview of techniques to guarantee the safety, confidentiality and dignity of survivo...rs, their families and communities. It includes terms, ethical questions and practical concerns associated with covering GBV, as well as an overview of some of the organisations involved in both combatting GBV and providing support services for survivors.

Antibiotics and other antimicrobial agents are invaluable life savers, particularly in resource-limited countries where infectious diseases are abundant. Both uncomplicated and severe infections are potentially curable as long as the aetiological agents are susceptible to the ...antimicrobial drugs. The rapid rate with which antimicrobial agents are becoming ineffective due to resistance acquired as a result of unchecked overuse and misuse threatens to undo the benefit of controlling infections. The evidence for resistant microorganisms, many times to more than a single antimicrobial agent, has been observed globally. In Tanzania, there is evidence in the form of few scattered studies conducted in different parts of the country in a multitude of settings including health care facilities, the community, domesticated animals and wild animals

The international community sits at the tipping pointof a post-‐antibiotic era, where common bacterial infections are no longer treatable with the antibiotic armamentarium that exists. In South Africa, t...he identification of the first case of pan-‐resistant Klebsiella pneumoniae(Brink et al, J Clin Microbiol. 2013;51(1):369-‐72) marks a watershed moment and highlights ourtip of the antibiotic resistance ‘iceberg’ in this country. Multi-‐drug resistant (MDR)-‐bacterial infections, predominantly in Gram-‐negative bacteria such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosaand Acinetobacter baumanniiare now commonplace in South African hospitals. Whilst a number of expensive new antibiotics for Gram-‐positive bacterial infections have been manufactured recently (some of which are licenced for usein South Africa), no new antibiotics active against Gram-‐negative infections are expected in the next 10-‐15years. Hence what we have now, needs conserving
