Over 18 months into the pandemic, WHO continues to conductglobal surveillance of COVID-19as part of activities on preparedness, readiness and response activities. The need for global surveillance of COVID-19 is greater than ever, asthe implementation of vaccination campaigns and the appearance of va...riants are prone to impact the course of the epidemic, as transmission patterns evolve. Timely and complete surveillance data are key to monitoring these changes.
Features include stratification by age and sex, trends over time, case fatality ratios by age, testing, hospitalization, and data on health workers –all visible at country and regional levels. The dashboard provides the ability for users to conduct further analyses by country and selected time period.

This practical guideline establishes definitions for “contact”, “contact person”, “contact tracing” and other associated concepts. It allows for improvement of contact tracing strategies and provides recommendations attempting to answer some, though not all, questions that arose during t...he 2019 coronavirus pandemic and other outbreaks. The use of this guideline begins once people have been diagnosed and the potential for transmission exists. It is not, however, intended to assist with case investigation. The guideline empowers health workers, governments, and public health officials with the tools to implement effective contact tracing strategies.

Background: In 2011, the demographic and health survey (DHS) in Cameroon was combined with the multiple indicator
cluster survey. Malaria parasitological data were collected, but the survey period did not overl...ap with the high
malaria transmission season. A malaria indicator survey (MIS) was also conducted during the same year, within the
malaria peak transmission season. This study compares estimates of the geographical distribution of malaria parasite
risk and of the effects of interventions obtained from the DHS and MIS survey data.

The purpose of this guidance is to assist WHO Member States, and other stakeholders, in the establishment and development of programmes of integrated surveillance of antimicrobial resistance in foodborne bacteria (i.e., bacteria commonly transmitted by food). In this guidance, “integrated surveill...ance of antimicrobial resistance in foodborne bacteria” is defined as the collection, validation, analyses and reporting of relevant microbiological and epidemiological data on antimicrobial resistance in foodborne bacteria from humans, animals, and food, and on relevant antimicrobial use in humans and animals. Integrated surveillance of antimicrobial resistance in foodborne bacteria therefore includes data from relevant food chain sectors (animals, food and humans) and includes data on both antimicrobial resistance and antimicrobial use. Integrated surveillance of antimicrobial resistance for foodborne bacteria expands on traditional public health surveillance to include multiple elements of the food chain, and to include antimicrobial use data, to better understand the sources of infection and transmission routes.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

The video titled "Ganemos tiempo: podría ser tuberculosis" (Let's save time: it could be tuberculosis) is part of a public health campaign aimed at raising awareness about tuberculosis (TB). It emphasizes the importance of early detection and timely treatment to combat the disease effectively. The ...video highlights common symptoms of TB, such as persistent cough, weight loss, and fever, and encourages individuals experiencing these signs to seek medical attention promptly. By doing so, it aims to reduce transmission rates and improve health outcomes.

n response to the outbreak, the Africa Centres for Disease Control and Prevention (Africa CDC) has been supporting African Union Member States in responding to the COVID-19 pandemic through a variety of interventions such as non-pharmaceutical interventions, quarantine, testing, isolation, contact t...racing, and clinical management. The Test to Treat guideline aims to increase continental testing efforts and reduce COVID-19 transmission in Africa and put-up response measures to control the impact of the virus, both to limit spread and to reduce substantially the risks of severe health outcomes related to COVID-19 infection. These countermeasures include highly effective vaccines and boosters, rapid testing options for monitoring exposure, and effective therapeutic options for both pre-exposure prevention and treatment of mild-to-moderate disease, oxygen therapy for moderate-severe disease, all of which can potentially be updated efficiently as new variants emerge that may affect the effectiveness of the available tools.

he tool will also provide visualization of the results after the SPPA is carried out. This protocol helps to plan surveys and mass drug administration activities that are more efficient and effective than what is done currently. The tool is being piloted in Kenya for schistosomiasis and designed suc...h that it can be expanded to other countries and programs. As of April 2024, you can open the tool to review geographic areas that are more/less environmentally suitable for the transmission of Schistosomiasis, analyze historical prevalence data, and determine which administrative units are to receive practical or precision assessments.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

the current surge in cases follows unprecedented flooding that began in mid-June 2022. With the current flood crisis affecting the national health system capacity and the growing humanitarian situation, there is a high risk of serious health impacts from dengue fever and other concurrent disease out...breaks. High population movement between Pakistan and bordering countries (in particular, Afghanistan and the Islamic Republic of Iran) means that the international transmission of dengue fever cannot be ruled out.

The rapid assessment tool (RAT) is meant to assess health facilities within mpox-affected areas that have at least one inpatient bed. Depending on time and resources available, certain facilities may be prioritized during an mpox outbreak. The RAT evaluates 16 infection prevention and control (IPC) ...and water, sanitation and hygiene (WASH) criteria identified as the minimum essential elements required for safe patient care and prevention of transmission within the health facility during readiness or response activities for outbreaks of mpox.

Introduction Pharmacovigilance (PV) systems to monitor drug and vaccine safety are often inadequate in sub-Saharan
Africa. In Malawi, a PV enhancement initiative was introduced to address major barriers to PV.
Objective The objective of this initiative was to improve reporting of adverse events (A...Es) by strengthening passive safety
surveillance via PV training and mentoring of local PV stakeholders and healthcare providers (HCPs) at their own healthcare
facilities (HCFs).
Methods An 18-month PV training and mentoring programme was implemented in collaboration with national stakeholders,
and in partnership with the Ministry of Health, GSK and PATH. Two-day training was provided to Expanded Programme on
Immunisation coordinators, identified as responsible for AE reporting, and four National Regulatory Authority representa-
tives. Abridged PV training and mentoring were provided regularly to HCPs. Support was given in upgrading the national
PV system. Key performance indicators included the number of AEs reported, transmission of AE forms, completeness of
reports, serious AEs reported and timeliness of recording into VigiFlow.
Results In 18 months, 443 HCPs at 61 HCFs were trained. The number of reported AEs increased from 22 (January 2000 to
October 2016) to 228 (November 2016 to May 2018), enabling Malawi to become a member of the World Health Organization
Programme for International Drug Monitoring. Most (98%) AE report forms contained mandatory information on reporter,
event, patient and product, but under 1% were transmitted to the national PV office within 48 h.
Conclusion Regular PV training and mentoring of HCPs were effective in enhancing passive safety surveillance in Malawi,
but the transmission of reports to the national PV centre requires further improvement.

This country profile presents a summary and analysis of Argentina's status with yellow fever. It is part of a series of profiles on this topic, each focusing on a different country in the Region of the Americas. Argentina's geographical location presents a wide territorial extension throughout diffe...rent latitudes, which determines a wide climatic variety, maintaining the conditions for the enzootic transmission of the yellow fever virus in jungle areas of the northeast of the country bordering Brazil and Paraguay. After controlling the major urban epidemics that hit the port city of Buenos Aires in the 20th century, Argentina maintains foci of enzootic activity in the northeast and isolated human cases for jungle acquisition. The increases in viral activity usually occur in a regional context of epizootics that affect southern Brazil and eastern Paraguay. Argentina has not presented autochthonous cases since 2008. Outbreaks have been sporadic with long intervals without evidence of viral activity.

TNew data from the World Health Organization reveal that the COVID-19 pandemic has disrupted malaria services, leading to a marked increase in cases and deaths.
According to WHO’s latest World malaria report, there were an estimated 241 million malaria cases and 627 000 malaria deaths worldwide i...n 2020. This represents about 14 million more cases in 2020 compared to 2019, and 69 000 more deaths. Approximately two-thirds of these additional deaths (47 000) were linked to disruptions in the provision of malaria prevention, diagnosis and treatment during the pandemic.
As in past years, the report provides an up-to-date assessment of the burden of malaria at global, regional and country levels. It tracks investments in malaria programmes and research as well as progress across all intervention areas. This latest report draws on data from 87 countries and territories with ongoing malaria transmission.

Countries around the world are facing the challenge of increased demand for care of people with COVID-19, compounded by fear, misinformation and limitations on movement that disrupt the delivery of health care for all conditions. Maintaining essential health services: operational guidan...ce for the COVID-19 context recommends practical actions that countries can take at national, subregional and local levels to reorganize and safely maintain access to high-quality, essential health services in the pandemic context. It also outlines sample indicators for monitoring essential health services, and describes considerations on when to stop and restart services as COVID-19 transmission recedes and surges. This document expands on the content of pillar 9 of the COVID-19 strategic preparedness and response plan, supersedes the earlier Operational guidance for maintaining essential health services during an outbreak, and complements the recently-released Community-based health care, including outreach and campaigns, in the context of the COVID-19 pandemic. It is intended for decision-makers and managers at the national and subnational levels.

Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms. Under natural conditions, the principal transmissio...n modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.
