This guide is intended for people involved in the management and operation of small- to mediumsized organized water supply systems. The content has been developed with particular consideration for operational-level personnel with responsibility for chlorination (for example, water treatment plant op...erators and technicians). The material presented within this guide may also be relevant for engineers and representatives from public health, local government, non-governmental organizations, as well as any other individuals supporting water safety planning activities for the supply of safe drinking-water.
Part 1. Chlorination principles: Describes key chlorination concepts, providing a knowledge foundation for the implementation of effective chlorination practices.
Part 2. Chlorination practices: Describes the practical application of the concepts presented in Part 1, including calculations and procedures for safe and effective chlorination of drinking-water supplies.

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorde...d in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.

Safe excreta disposal is a top priority in an emergency, but one that takes time and extensive resources to implement. This Technical Briefing Note examines the use of poo bags for safe excreta containment and disposal in urban emergency settings. The Brief also explores ways of building more comple...te excreta management systems to ensure not only safe disposal, but also to ensure the dignity and safety of users.

The agenda focuses on six critical changes necessary for more children suffering from SAM to access effective treatment. Building on lessons from the last decade, and the experiences of other successful health initiatives, the agenda addresses issues ranging from the creation of a more enabling envi...ronment to stronger mechanisms for tracking progress. It provides a diagnosis of the key challenges in each of these areas to-date and the specific solutions needed to turn things around over the next five years. These solutions require a collective effort at global, regional and national levels. The Agenda lays out Action Against Hunger’s commitments and contributions to these joint efforts

Updated 6 September 2016. This guidance has been developed to provide advice on the prevention of potential sexual transmission of Zika virus. The primary transmission route of Zika virus is via the Aedes mosquito. However, sexual transmission of Zika virus may also be possible, with limited evidenc...e recorded in a few cases. This is of concern due to an association between Zika virus infection and potential complications, including microcephaly and Guillain-Barré syndrome.

Kenya reported its first case of COVID-19 on 12 March 2020 and, as at 7 April 2020, 172 cases had been confirmed and 6 deaths reported. The Government of Kenya has taken a number of measures to curb the spread of the virus, including implementing a curfew, restricting movement out and into four coun...ties, including Nairobi Metropolitan, and closing most of the urban and rural markets to enforce social distancing. However, these measures, along with the global economic shock caused by the pandemic, are expected to generate new needs, requiring an immediate and urgent response.

COVID-19 has altered health sector capacity in low-income and middle-income countries (LMICs). Cost data to inform evidence-based priority setting are urgently needed. Consequently, in this paper, we calculate the full economic health sector costs of COVID-19 clinical management in 79 LMICs under di...fferent epidemiological scenarios.

Spread of resistance to antimicrobial agents (AMR) does not know national borders and has reached dimensions, which require immediate actions at the national, regional and global levels.
Antibiotic resistance is a natural biological response to improper use of antimicrobial agents (AMA); increasing... number of essential drugs, which become ineffective, contributing to selection, survival and replication of resistant strains of microorganisms. When chosen antimicrobials prove to be ineffective, the second- or third-line drugs need to be used although
in the majority of cases these drugs are more expensive, less safe and not always available.

Antimicrobial resistance (AMR) is a major public health challenge, which is recognized as high priority area by the Government of India. The increasing consumption of antibiotics is one of the key drivers of antimicrobial resistance seen in bugs of public health importance. Irrational prescription o...f broad-spectrum antibiotics, poor regulations around sale of antibiotics, self-medication, lack of education and awareness regarding responsible use of antibiotics have been identified as some of the key factors driving antimicrobial resistance in our country. The ‘National Health Policy’ (2017), addresses antimicrobial resistance as one of the key issues and prioritises development of guidelines regarding antibiotic use, limiting the over-the-counter use of antibiotics, restricting the use of antibiotics as growth promoters in livestock, and pharmaco-vigilance including prescription audit inclusive of antibiotic usage in the hospital and community.
