Population movements have turned Chagas disease (CD) into a global public health problem. Despite the successful implementation of subregional initiatives to control vectorial and transfusional Trypanosoma cruzi transmission in Latin American settings where t...he disease is endemic, congenital CD (cCD) remains a significant challenge. In countries where the disease is not endemic, vertical transmission plays a key role in CD expansion and is the main focus of its control. Although several health organizations provide general protocols for cCD control, its management in each geopolitical region depends on local authorities, which has resulted in a multitude of approaches. The aims of this review are to (i) describe the current global situation in CD management, with emphasis on congenital infection, and (ii) summarize the spectrum of available strategies, both official and unofficial, for cCD prevention and control in countries of endemicity and nonendemicity. From an economic point of view, the early detection and treatment of cCD are cost-effective. However, in countries where the disease is not endemic, national health policies for cCD control are nonexistent, and official regional protocols are scarce and restricted to Europe. Countries of endemicity have more protocols in place, but the implementation of diagnostic methods is hampered by economic constraints. Moreover, most protocols in both countries where the disease is endemic and those where it is not endemic have yet to incorporate recently developed technologies. The wide methodological diversity in cCD diagnostic algorithms reflects the lack of a consensus. This review may represent a first step toward the development of a common strategy, which will require the collaboration of health organizations, governments, and experts in the field.

Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

Since the Alma Ata Declaration in 1978, community health volunteers (CHVs) have been at the forefront, providing health services, especially to underserved communities, in low-income countries. However, consolidation of CHVs position within formal health systems has proved to be complex and continue...s to challenge countries, as they devise strategies to strengthen primary healthcare. Malawi’s community health strategy, launched in 2017, is a novel attempt to harmonise the multiple health
service structures at the community level and strengthen service delivery through a team-based approach. The core community health team (CHT) consists of health surveillance assistants (HSAs), clinicians, environmental health officers and CHVs. This paper reviews Malawi’s strategy, with particular focus on the interface between HSAs, volunteers in community-based programmes and
the community health team. Our analysis identified key challenges that may impede the strategy’s implementation:
(1) inadequate training, imbalance of skill sets within CHTs and unclear job descriptions for CHVs; (2) proposed community-level interventions require expansion of pre-existing roles for most CHT members; and (3) district authorities may face challenges meeting financial obligations and filling community-level positions. For effective implementation, attention and further deliberation is needed on the appropriate forms of CHV support, CHT composition with possibilities of co-opting trained CHVs
from existing volunteer programmes into CHTs, review of CHT competencies and workload, strengthening coordination and communication across all community actors, and financing mechanisms. Policy support through the development of an addendum to the strategy, outlining opportunities for task-shifting between CHT members, CHVs’ expected duties and interactions with paid CHT personnel is recommended.

Burns are a global public health problem, accounting for close to 200,000 deaths annually. The majority of these occur in low- and middle-income countries, where a number of constraints complicate the public health task of addressing burns. While the primary prevention of burns in low- and middle-in...come countries is a pressing need, the World Health Organization (WHO) also actively encourages further development of burn-care systems, including the training of health-care providers in the appropriate triage and management of people with burns.

Brucellosis is widespread in both humans and livestock in many developing countries. The authors have performed a series of epidemiological studies on brucellosis in agro-pastoral areas in Tanzania since 2015, with the aim of the disease control. Previously, the potential of a community-based brucel...losis control initiative, which mainly consisted of the sale of cattle with experience of abortion and vaccinating calves, was assessed as being effective and acceptable based on a quantitative approach. This study was conducted to investigate the feasibility of community-based brucellosis control program using participatory rural appraisals (PRAs) and key-informant interviews. Four PRAs were performed together with livestock farmers and livestock and medical officers in 2017. In the PRAs, qualitative information related to risky behaviors for human infection, human brucellosis symptoms, willingness to sell cattle with experience of abortion, and willingness to pay for calf vaccination were collected, and a holistic approach for a community-based disease control project was planned. All of the communities were willing to implement disease control measures. To avoid human infection, education, especially for children, was proposed to change risky behaviors. The findings of this study showed that community-based disease control measures are promising.

Antimicrobial resistant (AMR) organisms are increasing globally, threatening to render existing treatments ineffective against many infectious diseases. In Africa, AMR has already been documented to be a problem for HIV and the pathogens that cause malaria, tuberculosis, typhoid, cholera, meningitis..., gonorrhea, and dysentery. Recognizing the urgent need for action, the World Health Assembly adopted the Global Action Plan on Antimicrobial Resistance in May 2015. In accordance with the Global Action Plan and to meet needs specific to Africa, Africa CDC will establish the Anti-Microbial Resistance Surveillance Network (AMRSNET). AMRSNET is a network of public health institutions and leaders from human and animal health sectors who will collaborate to measure, prevent, and mitigate harms from AMR organisms.

Pathogen genomic surveillance has become a priority for public health systems in recent years. Genomic sequencing is increasingly being used to characterize pathogens and monitor important public health priorities (e.g. poliovirus, influenza virus, Mycobacterium tuberculosis and Vibrio cholerae, ant...imicrobial resistance (AMR)). The decrease in cost and time of sequencing and the exponential development of bioinformatic pipelines have played a critical role in integrating pathogen genomics into routine public health surveillance. The coronavirus disease 2019 (COVID-19) pandemic has highlighted the role that sequencing plays in the surveillance of infectious diseases. Sequencing facilitates earlier detection, more accurate investigation of outbreaks, closer real-time monitoring of pathogen evolution and tailored development and evaluation of interventions to inform local to global public health decision-making and action. However, there remains a need to coordinate efforts, leverage and link existing surveillance and laboratory networks and capabilities, and systematically integrate genetic sequence data (GSD) with clinical and epidemiological data to strengthen its utility.

Mpox is a zoonotic disease caused by a double-stranded DNA virus that belongs to the Orthopoxvirus genus of the Poxviridae family. The disease presents with symptoms similar to smallpox but with a lesser severity. It was first discovered in 1958 when two outbreaks of a poxlike disease occurred in co...lonies of monkeys kept for research, hence the name ‘mpox. The first human case of mpox was recorded in 1970 in the Democratic Republic of the Congo (DRC), which has subsequently spread to other central and western African countries. There are two known clades of the virus: clade I and clade II. Clade I, which is most frequently reported from countries in Central Africa, tends to be more severe than clade II. Cameroon is the only country known to harbour both clades.

An estimated 1.3 billion people globally experience significant disability. This figure has grown over the last decade and will continue to rise due to demographic and epidemiological changes. In 2022, the World Health Organization launched the Global report on health equity for persons with disabil...ities. This report demonstrated that many persons with disabilities are still being left behind. Experiencing persistent health inequities, persons with disabilities die earlier, they have poorer health and functioning, and they are more affected by health emergencies than the general population. These differences are largely associated with unjust factors both inside and beyond the health sector and are avoidable. The Global Report called upon Member States to take actions to make health sector more inclusive for persons with disabilities through the primary health care approach. This will be essential for countries to make health coverage truly universal and to progress towards other health-related targets in the sustainable development goals.

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.
