Dengue is a mosquito-borne viral disease that has rapidly spread to all regions of WHO in recent years. Dengue virus is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. These mosquitoes are also vectors of chikungunya, yellow fever and Zik...a viruses. Dengue is widespread throughout the tropics, with local variations in risk influenced by climate parameters as well as social and environmental factors.

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically beg...in three to fourteen days after infection. This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.Recovery generally takes two to seven days. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is spread by several species of mosquito of the Aedes type, principally A. aegypti.The virus has five different types;infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. A number of tests are available to confirm the diagnosis including detecting antibodies to the virus or its RNA.

Le 11 mars 2020, le OMS qualifait la COVID-19 de pandémie. Deux ans plus tard, le virus poursuit ses ravages dans le monde, avec des répercussions tres graves pour les personnels de santé.
Le 11 mars 2020, le OMS qualifait la COVID-19 de pandémie. Deux ans plus tard, le virus poursuit ses ravages dans le monde, avec des répercussions tres graves pour les personnels de santé.
Un an après le début de la pandémie, la COVID-19 a changé le monde et continue de peser sur notre quotidien. La pandémie a mis en évidence les lacunes des systèmes de santé tandis que le personnel de santé a été exposé au virus de façon
disproportionnée. Tout au long de l’année pas...sée, les infirmières ont affiché leur volonté et leur souplesse
en s’adaptant à de nouvelles méthodes de travail. Des millions d’infections à la COVID-19 ont été signalées parmi les agents de santé dans le monde et, hélas, le Conseil International des Infirmières (CII) a enregistré près de 3 000 décès qui lui sont
imputables parmi les infirmières dans 60 pays. Il est probable que le chiffre réel soit beaucoup plus élevé, le nombre d’infections et de décès parmi les agents de santé restant impossible à évaluer avec précision dans la mesure où de nombreux systèmes et pays n’ont pas assuré le suivi de cette question capitale.
Sur le long terme, les effets de la COVID-19, dont la « COVID longue » et le syndrome de stress posttraumatique différé, pourraient avoir d’importants effets délétères, en particulier sur le personnel infirmie

A wide spectrum of disease severity has been described for Human African Trypanosomiasis (HAT) due to
Trypanosoma brucei rhodesiense (T.b. rhodesiense), ranging from chronic disease patterns in southern countries of East Africa to an increase in virulence towards the north. However, only limited d...ata on the clinical presentation of T.b. rhodesiense HAT is available. From 2006-2009 we conducted the first clinical trial program (I MPAMEL III) in T.b. rhodesiense endemic areas of
Tanzania and Uganda in accordance with international standards (ICH-GCP). The primary and secondary outcome measures were safety and efficacy of an abridged melarsoprol schedule for treatment of second stage disease. Based on diagnostic findings and clinical examinations at baseline we describe the clinical presentation of T.b. rhodesiense HAT in second stage patients from two distinct geographical settings in East Africa.

Rabies is a vaccine-preventable, zoonotic, viral disease affecting the central nervous system. Once clinical symptoms appear, rabies is virtually 100% fatal. In up to 99% of cases, domestic dogs are responsible for rabies virus transmission to humans. Yet, rabies can affect both domestic and wild an...imals. It spreads to people and animals via saliva, usually through bites, scratches or direct contact with mucosa (e.g. eyes, mouth or open wounds). Children between the age of 5 and 14 years are frequent victims.

In the Indian state of Bihar, visceral leishmaniasis (VL) is a major public health issue that has been aggravated by the rising incidence of new Human immunodeficiency virus (HIV) infections. In endemic areas, the risk of VL infections in patients living with HIV (PLHIV) is higher. It is important t...o investigate the disease-related knowledge, attitude, and practices (KAP) of PLHIV in Bihar in order to monitor HIV/VL co-infection. Adequate knowledge, a positive attitude, and good practices for VL control are essential to stamp out the disease. This study investigated the KAP towards VL in HIV patients attending antiretroviral therapy (ART) clinic at ICMR-RMRIMS, Patna.

The Africa Centres for Disease Control and Prevention (Africa CDC) was established in 2017, after the west Africa Ebola virus disease outbreak. Upon creation, the
role of Africa CDC was to mandate strengthening of the capacity of public health institutions in Africa to prevent, detect, and respond ...to disease threats, based on science, policy, and data-driven interventions and programmes, as envisaged by the Abuja Declaration. The inaugural strategic plan was focused on building health systems for emergency preparedness and response. However, from its inception, the organisation recognised the concomitant need to comprehensively strengthen systems to prevent and manage noncommunicable diseases (NCDs) and injuries, and to face the neglected issue of mental health disorders. The division dedicated to these issues was conceptualised, but operationalisation was deferred to a future date.

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.

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.
