Hygiene common. Such body deformities often lead to social stigma and sub-optimal mental health, loss of income- earning opportunities and increased medical expenses for patients and their caretakers. The socioeconomic burdens of isolation and poverty are immense. Acute episodes of local inflammation involving skin, lymph nodes and lymphatic vessels often accompany chronic lymphoedema or elephantiasis. Some of these episodes are caused by the body’s immune response to the parasite. Most are the result of secondary bacterial skin infection where normal defences have been partially lost due to underlying lymphatic damage. These acute attacks are debilitating, may last for weeks, and are the primary cause of lost wages among persons suffering with lymphatic filariasis. Togo: first country in sub-Saharan Africa to eliminate lymphatic filariasis 8 April 2017 | Brazaville | Geneva The World Health Organization (WHO) has added Togo to a growing list of countries that have recently eliminated lymphatic filariasis as a public health problem. Togo becomes the first sub-Saharan country to have achieved this global target established by the 50th World Health Assembly. “Togo’s achievement is a milestone for Africa” said Dirk Engels, Director, WHO Department of Control of Neglected Tropical Diseases. “It demonstrates how the co-implementation of large-scale treatment of affected populations and management of morbidity can be addressed to eliminate another avoidable neglected tropical disease.” For the past 15 years, Togo carried out a sustained campaign in all affected districts and areas. In 2010, it moved into a 5-year surveillance phase until elimination was validated by WHO in 2015. Cleaning up London’s air Every year, over 9,000 Londoners are said to be dying prematurely from long-term exposure to air pollution and the latest research shows that hundreds of schools are located in areas exceeding safe legal pollution levels. Mayor Sadiq Khan is implementing tough measures to reduce London’s deadly air pollution and protect the health and wellbeing of all Londoners. These include: * From October 2017, a £10 toxicity charge or T-Charge will apply to the oldest and most polluting vehicles in Central London. Drivers will be paying £21.50 total during peak congestion, so the message here is clear - polluting vehicles aren’t welcome. TfL and the Mayor have also launched a free online vehicle checker - so you can check if your vehicle will be charged. * The world’s first Ultra Low Emission Zone (ULEZ) is proposed to start as early as 2019 - superseeding the T-charge and creating stricter emissions standards for diesel vehicles, 24 hours, 7 days a week. Those that do not comply will face a charge. This is expected to reduce harmful NOx (Nitrogen Oxides) emissions by about 50% in central London, 40% in inner London and 30% in outer London. * London’s buses * The Mayor is spending more than £300m to transform London’s bus fleet by retrofitting thousands of buses and committing to phase out pure diesel double decker buses from 2018. * Twelve Low Emission Bus Zones will put the greenest buses on the capital’s most polluted routes, with the first located in Putney High Street and Brixton Road. The zones are expected to reduce NOx emissions by 84% and thousands of schoolchildren in these areas will benefit from cleaner air. * London and Paris will be launching a new vehicle scoring scheme to help reduce the number of polluting vehicles in their cities. The Cleaner Vehicle Checker will show Londoners how much toxic NOx new cars emit, helping them to choose and buy less polluting vehicles. It will also strongly encourage manufacturers to build cleaner vehicles sooner. Africa Water, Sanitation & Hygiene • May - June 2017 37
