Desde março de 2020, quando a Organização Mundial de Saúde declarou que o mundo vivia uma pandemia de covid-19, acompanhamos um quadro sanitário sem precedentes nos últimos 100 anos. As medidas atuais contra a ...doença têm como objetivo o controle da transmissão e envolvem ações individuais e coletivas de higiene e distanciamento físico, enquanto a busca por uma vacina se apresenta como a esperança para vencer a pandemia. Considerando o contexto social de clamor por uma nova vacina, este ensaio crítico discute o paradoxo e as contradições da relação indivíduo-sociedade no contexto da covid-19 à luz da hesitação vacinal como fenômeno histórico e socialmente situado. Este ensaio aponta que as tomadas de decisão sobre (não) vacinar ou sobre (não) seguir as medidas preventivas e de controle da propagação da covid-19 são conformadas por pertencimentos sociais e atravessadas por desigualdades que tendem a se exacerbar. A infodemia que cerca a covid-19 e a hesitação vacinal refletem a tensão entre o risco cientificamente validado e o risco percebido subjetivamente, também influenciada pela crise de confiança na ciência. Percepções de risco e adesão a medidas de saúde extrapolam aspectos subjetivos e racionais e espelham valores e crenças conformados pelas dimensões política, econômica e sociocultural.

Centre Africain de contrôle et de prévention des maladies (CDC Afrique) protocole par la surveillance renforcée du syndrome respiratoire aigu sévère (SRAS) et du syndrome grippal pour COVID-19 en Afrique
Mars 2020
Le nombre d’États membres de l’Union signalant des cas de COVID-19 est ...en augmentation et il est probable que la transmission communautaire en Afrique se produira. L’OMS a récemment modifié la définition de cas suspect de COVID-19 pour inclure des infections respiratoires aiguës sévères et conseille de tester tous les cas de syndrome respiratoire aigu sévère (SRAS).1 Cependant, de nombreux États membres n’ont pas encore commencé à mettre en œuvre ces changements, ils concentrent toujours leurs efforts
de surveillance sur les personnes ayant des antécédents de voyage vers une zone de transmission locale de COVID-19. Cela signifie que les patients présentant des symptômes similaires, mais sans aucun contact apparent, peuvent ne pas être enquêtés.

A manual on homemade masks
This guide is designed to provide a simple outline of best practices to make, use and reuse masks to enable NGOs and individuals to self-create such masks and accelerate widespread adoption of masks across India.
The key criteria for proposed designs are:
Ease of Ac...cess to Materials
Easy of Making at Home
Ease of Use and Reuse
Wearing of masks is especially recommended for people living in densely populated areas across India

Handbook for HIV/Aids Training
This document sets out key messages to support malaria prevention and control efforts, for teachers, pupils and the wider community. It is designed to facilitate health education in schools by encouraging teachers to guide pupils through the core messages about malaria and emphasise the most importa...nt points. Pupils are expected to actively engage by taking notes and applying what they learn. Ultimately, the goal is to equip children with the practical knowledge to influence behavioural change at both the individual and community levels.

The document "Prevansyon kont Diare" provides guidance on preventing and managing diarrhea. It explains that diarrhea, caused by pathogens like viruses, bacteria, and parasites, can lead to severe dehydration if untreated. Symptoms include vomiting, fever, and loss of appetite, with severe cases req...uiring urgent medical care.
To prevent diarrhea, the document emphasizes using treated or boiled water, washing hands with soap, cooking food thoroughly, and cleaning fruits and vegetables with safe water. It also provides a recipe for Oral Rehydration Solution (ORS) to combat dehydration: mix 1 liter of boiled or treated water with 8 teaspoons of sugar, 1 teaspoon of salt, and a pinch of baking soda. This solution should be consumed while seeking medical attention.
The document serves as an educational resource to promote hygiene and provide simple, effective solutions for preventing and managing diarrhea.

This infographic from the Tropeninstitut illustrates the malaria transmission cycle. It begins when an Anopheles mosquito bites a human and injects its sporozoites into the bloodstream. The sporozoites then travel to the liver where they mature and release merozoites back into the bloodstream. The m...erozoites then infect red blood cells, resulting in the clinical symptoms of malaria. Some merozoites develop into gametocytes, which can be ingested by another mosquito when it bites the infected person again, thus continuing the transmission cycle.
The infographic serves as an educational tool, helping to explain the complex life cycle of the malaria parasite and the role of mosquitoes in spreading the disease.

Antimalarial chemotherapy is crucial for reducing morbidity, mortality, and drug resistance, and is the cornerstone of malaria control. Existing antimalarial drugs act at different stages of the parasite’s life cycle. These drugs range from classic agents such as chloroquine and quinine to newer a...rtemisinin derivatives. They include tissue schizonticides, blood schizonticides, gametocytocides, and sporontocides. Artemisinin and its derivatives are the most effective and fastest-acting treatment against drug-resistant Plasmodium falciparum, achieving rapid parasite clearance and reducing transmission potential. Other key drugs include mefloquine, halofantrine, proguanil, sulfadoxine–pyrimethamine, atovaquone–proguanil, tetracyclines, clindamycin and azithromycin. Each of these drugs has a specific mechanism of action, pharmacokinetics, efficacy, safety profile and contraindications. Rational drug combinations and adherence to national treatment guidelines are essential for managing resistance, ensuring safety in vulnerable populations such as children and pregnant women, and optimising therapeutic outcomes in cases of both uncomplicated and severe malaria.

A pesar de los avances, persisten importantes barreras para el diagnóstico y tratamiento oportunos de la malaria en las Américas, especialmente en zonas rurales y de difícil acceso. Para reducir la transmisión, es esencial ampliar el uso de pruebas de diagnóstico rápido y garantizar la disponi...bilidad gratuita de antimaláricos como bienes públicos. La OPS propone un marco estratégico para eliminar obstáculos, acelerar el inicio del tratamiento y contribuir a la eliminación de la enfermedad en la región.

This website provides comprehensive guidance on vaccinations, malaria prevention and general health measures for travellers to tropical and developing regions. It emphasises two main vaccination criteria: the administrative requirements of the destination country and the actual health risks to the t...raveller. Malaria prevention measures include chemoprophylaxis (e.g. atovaquone-proguanil, doxycycline or mefloquine) and vector control methods such as insecticide-treated nets, insect repellents and environmental protection measures. Additional travel health risks covered include bites from other arthropods, envenomations, dog and mammal bites, food and water hygiene, traveller's diarrhoea, and considerations for pregnant women, infants, the elderly, and people with chronic conditions. It strongly recommends carrying a travel medical kit and having a pre-travel consultation. Overall, the document aims to minimise illness and ensure safe travel.

Combination therapy is a cornerstone of modern malaria treatment, particularly in the context of widespread multidrug resistance. Using two or more antimalarial drugs with different mechanisms simultaneously enhances efficacy, shortens treatment duration, improves compliance and delays the developme...nt of resistance. Artemisinin-based combination therapies (ACTs), such as artemether–lumefantrine, artesunate–amodiaquine and artesunate–sulfadoxine/pyrimethamine, are highly effective in rapidly clearing parasites and reducing gametocyte carriage. They are also generally well tolerated. Non-artemisinin combinations, quinine-based regimens and novel combinations (e.g. piperaquine–dihydroartemisinin) offer alternative therapeutic options, although clinical experience with these remains limited. Although ACTs are the preferred first-line treatment, factors such as cost, local drug resistance patterns, safety during pregnancy and paediatric use must inform implementation and policy decisions.
