In many countries neonatal tetanus is responsible for half of all neonatal deaths due to vaccine-preventable diseases and for almost 14% of al¡ infant deaths. It is estimated that in the 1970s more than 10,000 newborns died annually from neonatal tetanus in the Americas. Neonatal tetanus is prevent...ed by immunization and/or assuring clean delivery and post-delivery practices.

Coronaviruses are a large family of viruses that are known to cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).
As of 21 May 2020, 4.8 million confirmed cases of Coronavirus disease 2019 (COVID-19) have been reported globally. In South America, COVID-19 was first detected on 26 February 2020, when Brazil confirmed a case in São Paulo.
Whole-genome sequencing (WGS) provides a vast amount of information and the highest possible resolution for pathogen subtyping. The application of WGS for global surveillance can provide information on the early emergence and spread of AMR and further inform timely policy development on AMR control.... Sequencing data emanating from AMR surveillance may provide key information to guide the development of rapid diagnostic tools for better and more rapid characterization of AMR, and thus complement phenotypic methods. This document addresses the applications of WGS for AMR surveillance, including the benefits and limitations of current WGS technologies

SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

MEDBOX Issue Brief 26. Cholera is an acute diarrhoeal infection caused by eating or drinking food or water that is contaminated with the
bacterium Vibrio cholerae. Cholera remains a global threat to public health and is an indicator of inequity and lack of
social development. Researchers have esti...mated that every year, there are 1.3 to 4.0 million cases of cholera, and 21
000 to 143 000 deaths worldwide due to the infection.
However, cholera remains a neglected and underreported disease. Many cases are not recorded due to limitations in
surveillance systems and fears of potential impact on trade or tourism.
Today cholera affects 47 countries across the globe. Almost every developing country faces cholera outbreaks or
the threat of cholera. Major ongoing outbreaks are being reported from Afghanistan, Bangladesh, Democratic
Republic of Congo, Ethiopia and Nigeria. Major outbreaks are currently in Syria and Haiti.
Therefore, MEDBOX decided to produce issue briefs on cholera and available resources in Arabic, English and
French.

Human Papilloma Virus (HPV) is the most common sexually transmitted infection, and two types of HPV (16 and 18) cause nearly 50% of high-grade cervical pre-cancers. HIV and cervical cancer are inextricably linked. Women living with HIV are six times more likely to develop cervical cancer, which is o...ne of the AIDS-defining illnesses and the most common cancer among women living with HIV globally. Cervical cancer is a preventable, curable disease and can be eliminated as a public health problem with primary and secondary prevention, treatment, and care of cervical cancer, in combination with addressing social, health and other inequalities and integrated approaches.

The development of this target product profile (TPP) was led by the WHO Department of Control of Ne-
glected Tropical Diseases (NTD) following standard WHO guidance for TPP development. In order to
identify and prioritize diagnostic needs, a WHO NTD Diagnostics Technical Advisory Group (DTAG)
was... formed, and different subgroups were created to advise on specific NTDs, including a subgroup
working on the human African trypanosomiasis (HAT) diagnostic innovation needs. This group of in-
dependent experts included leading scientists, public health officials and endemic-country end-user rep-
resentatives. Standard WHO Declaration of Interest procedures were followed. A landscape analysis of
the available products and of the development pipeline was conducted, and the salient areas with unmet
needs were identified

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Nigeria reported its first case of COVID-19 at the end of February 2020 and subsequently experienced
four waves, with peaks in June 2020 and January, August and December 2021. The COVID-19 pandemic
severely impacted the economy of Nigeria and caused disruption of health services nationwide. During... the crisis, many Nigerians failed to access routine health
services due to decreased income and lockdown
restrictions. The most significant service disruptions
were in maternal and newborn health, vaccination,
sick childcare, family planning and noncommunicable
disease treatment services (1). Pregnant women
were anxious about contracting COVID-19 during
2020, and as a result, many avoided attending health
facilities for antenatal (ANC) and postnatal care (PNC).
Disruptions in the medical supply chain and diversion
of resources to COVID-19 management impacted on
essential health services. Health workers were often
unable to go to work because of transport disruptions
or illness
