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.

Effective malaria case management requires quick access to diagnostics and antimalarial treatments to reduce illness and death. Artemisinin-based combination therapy (ACT) has been essential to malaria treatment since 2001, as it combines artemisinin for rapid parasite reduction with a partner drug ...to ensure complete cure. However, resistance to antimalarial drugs, where parasites survive standard doses, threatens malaria control.

This document serves to provide interim guidance/ recommendations to carry out mpox surveillance activities mainly case investigation, contact tracing and isolation. For the development of this document WHO, UKHSA and CDC guidelines were referred to and adopted within the country context.
The conditionality of this recommendation is largely driven by the current higher unit cost of pyrethroid-PBO ITNs compared
to pyrethroid-only LLINs and therefore the uncertainty of their cost-effectiveness. Furthermore, as PBO is less wash-resistant
than pyrethroids, its bioavailability declines ...faster over the three-year estimated life of an ITN; therefore, the added impact of
pyrethroid-PBO ITNs over that of pyrethroid-only LLINs may decline over time. The evidence comes from two sites in
eastern Africa with pyrethroid resistance and not from other geographies where transmission levels and vector characteristics
may vary. PBO acts by inhibiting certain metabolic enzymes, primarily oxidases, and so are likely to provide greater protection
than pyrethroid-only LLINs where mosquitoes display mono-oxygenase-based insecticide resistance mechanisms.

Due to the heterogeneous distribution of malaria transmission and its determinants, subnational tailoring (SNT) provides an analytical framework to facilitate the targeting of each population with appropriate intervention packages for maximum impact to inform national strategic planning and prioriti...zation based on resources available. The WHO Global Malaria Programme recommends the use of subnational data on disease epidemiology and other relevant local contextual factors to facilitate the process of SNT. Once the strategies and intervention mixes have been defined, programmes can proceed to the prioritization of
interventions for effective programming, based on available resources

Anopheles stephensi, a highly competent vector of Plasmodium falciparum and P. vivax, is considered an efficient vector of urban malaria. Until 2011, the reported distribution of An. stephensi was confined to certain countries of South Asia and parts of the Arabian Peninsula. Since then, the vector ...has been collected in Djibouti (2012), Ethiopia (2016), Sudan (2016), Sri Lanka (2017), Somalia (2019), and most recently Nigeria (2020) and Yemen (2021). WHO considers the spread of An. stephensi to be a major potential threat to malaria control and elimination in Africa and southern Asia and has recently launched an initiative against the spread of this vector in Africa.

Las olas de transmisión de la fiebre amarilla ocurridas en la Región de las Américas entre el 2016 y el 2018 causaron el mayor número de casos humanos y epizoóticos registrados en varios decenios. La fiebre amarilla es una enfermedad hemorrágica viral grave que representa un desafío para el p...rofesional de salud: exige el reconocimiento temprano de signos y síntomas muchas veces inespecíficos, que pueden parecerse a otros síndromes febriles agudos. La detección temprana de los casos sospechosos o confirmados, el monitoreo de los signos vitales y las medidas de soporte vital, y el tratamiento de la insuficiencia hepática aguda siguen siendo las estrategias recomendadas para el manejo de los casos. El presente informe es el resultado de las deliberaciones sobre la experiencia de expertos de la Región en cuanto al manejo clínico de pacientes con fiebre amarilla, especialmente en brotes y epidemias, mediante la contextualización de esa experiencia en el conjunto actual de la evidencia médico-científica y la consideración de las directrices técnicas ya disponibles en los países de la Región. Presenta flujogramas para la evaluación inicial del paciente con sospecha clínica de fiebre amarilla y sugiere un conjunto mínimo de pruebas de laboratorio que puede ser útil cuando hay pocos recursos; además, detalla aspectos de la organización de los sistemas de salud para enfrentar brotes y epidemias de fiebre amarilla.
