При инфицировании в естественных условиях выработка иммунитета к патогенному микроорганизму проходит в несколько этапов и заним...ет от 1 до 2 недель. При вирусной инфекции врожденный иммунитет обеспечивает немедленную реакцию организма, которая заключается в активации неспецифического иммунного ответа, приводящего к замедлению инфекционного процесса макрофагами, нейтрофилами и дендритными клетками, и которая в ряде случаев обусловливает бессимптомное течение инфекции. Затем происходит активация адаптивного иммунного ответа, при котором в организме начинается выработка специфических антител, способных к связыванию с вирусными частицами. Данные антитела являются белками и носят название иммуноглобулинов. Кроме того, в организме образуются Т-клетки, способные распознавать и уничтожать другие клетки, пораженные вирусом. Это звено иммунитета носит название клеточного. Функционирование нескольких звеньев иммунитета при адаптивном ответе может способствовать элиминации вируса из организма, а при достаточной активности реакции – препятствовать переходу заболевания в тяжелую форму и повторному заражению той же инфекцией. Количественной мерой данного процесса является уровень антител в крови.

O protocolo a seguir foi desenvolvido para investigar o alcance da infecção, conforme determinado pela soropositividade da população geral, em qualquer país com casos confirmados de infecção pelo COVID-19. Os países talvez tenham que adaptar alguns aspectos deste protocolo para os respectivo...s sistemas de saúde pública, bem como sistemas laboratoriais e clínicos, de acordo com a capacidade, disponibilidade de recursos e adequação cultural. No entanto, usando-se um protocolo padronizado, tal como o descrito abaixo, dados de exposição epidemiológica e amostras biológicas podem sercoletados de forma sistemática, e rapidamente compartilhados em um formato que facilite sua agregação, tabulação e análise em diferentes cenários globais, para estimar prontamente a gravidade as taxas de ataque da infecção pelo vírus COVID-19, bem como embasar respostas de saúde públicae decisões relativas a políticas públicas. Isso é particularmente importante no contexto de um novo patógeno respiratório, como o COVID-19.

Aligned to the Lancet Migration Global Statement to include migrants and refugees incountries’response to COVID-19, this update focuses on Mexico’s challenges and opportunities to build an inclusive response that is based on a contextualized adaptation of there commendations published by th...e Lancet Migration. A critical component for this analysis is the recognition of migration as a social determinant of health, which acts as a major risk factor for populations subjected to violence, trauma and forced exile while in the face of a global pandemic.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference ...method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

Mass vaccination campaigns to prevent coronavirus disease 2019 (Covid-19) are occurring in many countries; estimates of vaccine effectiveness are urgently needed
to support decision making. A countrywide mass vaccination campaign with the
use of an inactivated severe acute respiratory syndrome c...oronavirus 2 (SARS-CoV-2)
vaccine (CoronaVac) was conducted in Chile starting on February 2, 2021.

Female genital mutilation (FGM), a violation of girls’ and women’s human rights, is becoming less common, and opposition to the practice is growing — in the last two decades, the proportion of girls and women who want the practice to stop has doubled.
However, progress is not universal. In s...ome countries, FGM is as common today as it was three decades ago. Even in places where the practice is on the decline, progress would need to be at least 10 times faster to meet the 2030 target for elimination. Additionally, an alarming trend is emerging: around 1 in 4 girls and women who have undergone FGM, or 52 million worldwide, were cut by health personnel. This proportion is twice as high among adolescents, indicating growth in the medicalization of the practice.
This brochure explores the global FGM trends — progress made in the past three decades, shifts in attitudes, and changes in the circumstances surrounding the practice.

WHO recommends prompt recognition of progressive acute hypoxaemic respiratory failure when a patient with respiratory distress is failing to respond to standard oxygen therapy and adequate preparation to provide advanced oxygen/ventilatory support.
Hypoxaemic respiratory failure in ARDS commonly ...results from intrapulmonary ventilation-perfusion mismatch or shunt and usually requires mechanical ventilation.
At any time, if there are urgent or emergent indications for intubation, do not delay.
We recommend prompt recognition of progressive acute hypoxaemic respiratory failure when a patient with respiratory distress is failing to respond to standard oxygen therapy and adequate preparation to provide advanced oxygen/ventilatory support.
WHO suggests that patients with severe or critical COVID-19 with acute hypoxaemic respiratory failure that do not require emergent intubation be treated with HFNO, or CPAP or NIV (BiPAP) over standard oxygen therapy.

“2022 was an eventful year for the WHO Country Office in Ghana,” says Dr Francis Kasolo, WHO Representative to Ghana.
In 2022, WHO Ghana collaborated with partners to deliver interventions in support of the Government of Ghana's health sector agenda to ensure healthy lives for all towards ach...ieving Universal Health Coverage. This 2022 annual report highlights some of the achievements that were chalked in our efforts to help promote the health and wellbeing of Ghanaians

Socioeconomic status is associated with differences in risk factors for cardiovascular disease incidence and outcomes, including mortality. However, it is unclear whether the associations between cardiovascular disease and common measures of socioeconomic status—wealth and education—differ among... high-income, middle-income, and low-income countries, and, if so, why these differences exist. We explored the association between education and household wealth and cardiovascular disease and mortality to assess which marker is the stronger predictor of outcomes, and examined whether any differences in cardiovascular disease by socioeconomic status parallel differences in risk factor levels or differences in management.
