ABSTRACT

HIV cluster detection and response (CDR) is a critical strategy to end the HIV epidemic by offering information to identify prevention and care services gaps. The risk metrics for HIV clusters can be classified into three groups: growth-based metrics, characteristic-based metrics, and phylogeny-based metrics. When identifying HIV risk clusters, the public health response can reach people in the affected networks, including people with undiagnosed HIV, people with diagnosed HIV who might not be accessing HIV care or other services, and people without HIV who would benefit from prevention services. To provide references for HIV precise prevention in China, we summarized the risk metrics and the intervention measures for CDR.

ABSTRACT

Objective: To quantitatively estimate the incidence of COVID-19 in different backgrounds, including vaccination coverage, non-pharmacological interventions (NPIs) measures, home quarantine willingness and international arrivals, and the demands of healthcare resource in Shanghai in the context of optimized epidemic prevention and control strategies. Methods: Based on the natural history of 2019-nCoV, local vaccination coverage and NPI performance, an age-structured Susceptible-Exposed-Infections-Removed (SEIR) epidemic dynamic model was established for the estimation of the incidence of COVID-19 and demand of hospital beds in Shanghai by using the data on December 1, 2022 as the basis. Results: Based on current vaccination coverage, it is estimated that 180 184 COVID-19 cases would need treatment in hospitals in Shanghai within 100 days. When the booster vaccination coverage reaches an ideal level, the number of the cases needing hospitalization would decrease by 73.20%. School closure or school closure plus workplace closure could reduce the peak demand of regular beds by 24.04% or 37.73%, respectively, compared with the situation without NPI. Increased willingness of home quarantine could reduce the number of daily new cases and delay incidence peak of COVID-19. The number of international arrivals has little impact on the development of the epidemic. Conclusions: According to the epidemiological characteristics of COVID-19 and the actual situation of vaccination in Shanghai, the incidence of COVID-19 and health resource demand might be reduced by increasing vaccination coverage and early implementation of NPI.

ABSTRACT

A dengue é uma doença dolorosa e debilitante transmitida por insetos da espécie Aedes aegypti. Ela é definida como uma doença viral que, nos últimos anos, se espalhou vertiginosamente por todas as regiões tropicais e subtropicais do planeta. Este estudo teve como objetivo identificar e discutir o número e a taxa de incidência de casos de dengue no estado do Paraná utilizando-se dos boletins emitidos por semana epidemiológica nos anos de 2016 a 2021, considerando a sazonalidade da doença. Também se objetivou debater a incidência por macrorregional, as possíveis causas de períodos epidêmicos e ações de combate vetorial para redução dos casos da patologia. Foram utilizados como fonte de informações o banco de dados da Dengue/SVS/SESA, por meio de informes técnicos, disponibilizados pelo portal online de Boletins da Dengue Paraná da Secretaria de Estado de Saúde do Paraná. Conclui-se que o ano epidemiológico de 2019/2020 foi o de maior incidência e os anos epidemiológicos 2016/2017 e 2017/2018 apresentaram os menores casos durante todo período analisado. Dessa forma, a vigilância epidemiológica é muito importante para avaliação espacial da distribuição de casos para execução de ações estratégicas para redução da infestação do vetor. As políticas públicas e a disponibilização de inseticidas para aplicação também são essenciais para o combate da Dengue.


Dengue is a painful and debilitating disease transmitted by insects of the Aedes aegypti species. It is defined as a viral disease that, in recent years, has spread vertiginously throughout the tropical and subtropical regions of the planet. This study aimed to identify and discuss the number and incidence rate of dengue cases in the state of Paraná using the bulletins issued by epidemiological week in the years 2016 to 2021, considering the seasonality of the disease. The aim was also to discuss the incidence per macro-region, the possible causes of epidemic periods, and vectorial combat actions to reduce the cases of the pathology. The Dengue/SVS/SESA database was used as a source of information, through technical reports, made available by the online portal of Dengue Paraná Bulletins of the Paraná State Health Department. It is concluded that the epidemiological year 2019/2020 was the one with the highest incidence and the epidemiological years 2016/2017 and 2017/2018 had the lowest cases during the entire period analyzed. Thus, epidemiological surveillance is very important for the spatial assessment of the distribution of cases to carry out strategic actions to reduce vector infestation. Public policies and the availability of insecticides for application are also essential to combat Dengue.

ABSTRACT

The COVID-19 pandemic is still ongoing in the world, the risk of COVID-19 spread from other countries or in the country will exist for a long term in China. In the routine prevention and control phase, a number of local COVID-19 epidemics have occurred in China, most COVID-19 cases were sporadic ones, but a few case clusters or outbreaks were reported. Winter and spring were the seasons with high incidences of the epidemics; border and port cities had higher risk for outbreaks. Active surveillance in key populations was an effective way for the early detection of the epidemics. Through a series of comprehensive prevention and control measures, including mass nucleic acid screening, close contact tracing and isolation, classified management of areas and groups at risk, wider social distancing and strict travel management, the local COVID-19 epidemics have been quickly and effectively controlled. The experiences obtained in the control of the local epidemics would benefit the routine prevention and control of COVID-19 in China. The occurrence of a series of COVID-19 case clusters or outbreaks has revealed the weakness or deficiencies in the COVID-19 prevention and control in China, so this paper suggests some measures for the improvement of the future prevention and control of COVID-19.

ABSTRACT

The Chilean Academy of Medicine convened a commission to evaluate the status of HIV epidemic and the national response to it, regarding its achievements, gaps and challenges, aiming to recommend actions to optimize assessment quality and national response. This publication summarizes the agreed upon opinion of its members. The epidemic is overwhelmingly sexually transmitted, predominant in homo/bisexual men. Vertical transmission is very low. An increasing number of new diagnoses is occurring, with relative over representation of foreign people lately. There is a legal guarantee of confidentiality, nondiscrimination and treatment for those affected, both in the private and public sector. All public health services have active HIV care units. Modern antiviral drugs and monitoring tests are also available. Despite these clear achievements, insufficient, occasionally inadequate public policies and certain rigid regulations thwart optimal effectivity and efficiency of the programs, contributing to the slow and incomplete compliance with international commitments. Shortcomings worth highlighting are: suboptimal educational and preventive programs directed to youngsters, vulnerable and general population; persistent underdiagnosis of infected population; cumbersome requirements to request and inform diagnostic tests, thus discouraging testing; excessive centralization and long latency of diagnosis confirmation and monitoring tests; incomplete epidemiologic analysis and public reporting of findings; non flexibility and slow updating of therapeutic guidelines; insufficient adaptation of care and drug delivery modalities to patients' needs; excessive administrative requirements at care centers and restrictive legislation for outcome and interventional clinical research. Recommendations to deal with these issues were proposed.

ABSTRACT

Reconhece-se que a população idosa que reside nas Instituições de Longa Permanência para Idosos (ILPI), em geral, é mais vulnerável, com níveis variados de dependência e possui necessidades complexas. Como a nova doença respiratória, COVID-19, que está se espalhando globalmente e que apresenta letalidade elevada na população idosa (pessoas com 60 anos ou mais), as ILPI devem implementar medidas de prevenção e controle de infecção para evitar ou reduzir ao máximo que os residentes, seus cuidadores e profissionais que atuem nesses estabelecimentos sejam infectados pelo vírus e, mais significativamente, reduzir a morbi-mortalidade entre os idosos nessas instituições. As medidas de prevenção que devem ser aplicadas são as mesmas para detectar e impedir a propagação de outros vírus respiratórios, como por exemplo a influenza. A doença classificada como COVID-19 é causa dada pelo novo coronavírus (SARS-CoV-2), que foi identificado pela primeira vez na cidade de Wuhan, na China. Outras infecções por coronavírus incluem o resfriado comum, a Síndrome Respiratória do Oriente Médio (MERS-CoV) e a Síndrome Respiratória Aguda Grave(SARS-CoV).Nesta Nota Técnica, serão abordadas orientações mínimas para as ILPI quanto às medidas de prevenção e controle que devem ser adotadas durante a assistência aos residentes, principalmente com relação aos casos suspeitos ou com diagnóstico confirmado de COVID-19, segundo as orientações divulgadas pela Organização Mundial da Saúde(OMS)e outros órgãos. No entanto, ressaltamos que este é um documento que pode ser alterado a qualquer momento, conforme novas informações estiverem disponíveis, já que se trata de um microrganismo novo no mundo e portanto, com poucas evidências sobre ele.

ABSTRACT

Resumo O artigo analisa a chegada e identificação do mosquito africano Anopheles gambiae no Brasil em 1930 e as primeiras reações de cientistas e autoridades de saúde pública contra as epidemias de malária causadas por essa espécie. Apesar de ter sido reconhecido como perigoso vetor da malária, sua presença em território nacional foi negligenciada a partir de 1932, após ações emergenciais na capital do Rio Grande do Norte, favorecendo um alastramento silencioso que resultou em uma grande epidemia de malária em 1938. São abordadas questões científicas e políticas que contribuíram para que o combate ao mosquito fosse colocado em segundo plano nas articulações entre a Divisão Sanitária Internacional da Fundação Rockefeller e autoridades brasileiras até 1937.


Abstract The article analyzes the arrival and identification of the African mosquito Anopheles gambiae in Brazil in 1930, and the initial reactions of scientists and public health authorities against the epidemics of malaria caused by this species. Although this mosquito was recognized as a dangerous vector of malaria, its presence in Brazil was neglected after initial emergency actions in the city of Natal in 1932; this encouraged it to spread silently, resulting in a major malaria epidemic in 1938. This article examines scientific and political issues which caused the fight against mosquitoes to be pushed into the background until 1937 in cooperative efforts between the Rockefeller Foundation's International Health Division and the Brazilian authorities.

ABSTRACT

Resumen Tras la Guerra Civil, las deficientes condiciones higiénico-dietéticas de gran parte de la población española favorecieron la aparición de enfermedades epidémicas. El tifus exantemático puso en jaque a las autoridades sanitarias, especialmente durante la primavera de 1941, cuando el ciclo epidemiológico de la enfermedad y la falta de infraestructuras se aliaron para provocar una grave crisis sanitaria. El régimen franquista, consciente de que esta situación dificultaba su legitimación, no dudó en utilizar la exclusión social como parte de su política sanitaria contra esta epidemia. El artículo analiza en profundidad el caso de Valencia, una ciudad que durante la guerra, por hallarse en la retaguardia republicana, había acogido sucesivas oleadas de refugiados a medida que avanzaban las tropas franquistas.


Abstract After the Spanish Civil War, poor hygiene and nutritional deficiencies among a large part of Spain's population contributed to the rise of epidemic diseases. Exanthematic typhus posed a challenge to the health authorities, especially during the spring of 1941, when the epidemiological cycle of the disease and the lack of infrastructures combined to create a serious health crisis. The Franco regime, aware that this situation posed a threat to its legitimacy, promptly used social exclusion as part of its health policy against the epidemic. This article provides an in-depth analysis of the case of Valencia, a city that was behind Republican lines during the war, and therefore received successive waves of refugees as Franco's troops advanced.

ABSTRACT

Resumen El artículo busca indagar en los proyectos de disciplinamiento sancionados por el Estado de la provincia de Mendoza (Argentina) durante la epidemia de cólera ocurrida en el verano de 1886 y 1887. Si bien los planes tenían como finalidad mejorar el estado sanitario de toda la población y de la ciudad, apuntaron y se aplicaron con mayor intensidad sobre los sectores populares y sus espacios. Esto se debió a las ideas y representaciones que en torno de la enfermedad y la muerte construyó el grupo dirigente durante estos periodos.


Abstract The article takes a look into the disciplinary projects approved by the authorities in the province of Mendoza (Argentina) during the cholera epidemic that took place during the summer of 1886-1887. Although the projects were intended to ameliorate the sanitary conditions of the whole of the population, these were focused and applied more intensively on the underprivileged sectors and their areas of inhabitance. This follows the ideas and representations created by the State regarding the illness and its death during this period.

ABSTRACT

Scorpions are distributed throughout Iran and the genus Hemiscorpius is particularly important in this region. Hemiscorpius lepturus is the most significant species within the genus in the country. Since scorpionism provoked by Hemiscorpius comprises a medical emergency, the present study is focused on this important issue. In order to perform the present work, a review of the medical and health-related literature was carried out in several databases. The current findings indicate that six species of Hemiscorpius are found in 15 states of Iran, mainly in the south and southwest. Deaths caused by stings were reported only for two species. The morphological characteristics and geographical distribution of H. lepturus in Iran, its venom and the toxic compounds, epidemiologic data and clinical manifestations of envenomation as well as treatment for affected people are herein reviewed and described. H. lepturus venom toxicity differs from other Iranian scorpions regarding duration and severity. Scorpionism is an important public health problem in Iran, especially in southwest and south regions and in urban areas. It is more prevalent in children and young people. H. lepturus venom is primarily a cytotoxic agent and has hemolytic, nephrotoxic and to some extent hepatotoxic activity. The use of polyvalent antivenom to prevent scorpion sting symptoms is recommended. A well-planned health education program might be useful in preventing scorpionism.
