El desarrollo de inmunidad a un patógeno por infección natural es un proceso de varias etapas que suele producirse a lo largo de una o dos semanas. El organismo responde a una infección vírica de forma inmediata a través de una respuesta innata no específ...ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

he Western Pacific is the world’s most disaster-prone region. When a disaster occurs, people may need to seek accommodation in a disaster evacuation shelter. However, it may be difficult for people in a disaster evacuation shelter to avoid confined and enclosed spaces with poor ventilation; crowde...d places with many people nearby; and close-contact settings, such as close-range conversations. This document outlines key considerations and strategies that should be considered for the establishment of a disaster evacuation shelter in the context of COVID-19. In particular, considerations and strategies as outlined for the preparedness, response and recovery phases of disasters.

Ethnic disparities in COVID-19 persist, with increased rates of infection, severe disease, and death among people from minority ethnic groups. COVID-19 vaccination rates also remain lowest in these communities compared with white people in the UK. Among people older than 18 years, the proportion who... have had three COVID-19 vaccinations in England in March, 2022, was lowest among Black Caribbean (38%), Black African (45%), and Pakistani (45%) ethnic groups. These disparities are likely to be attributed to the intersection of key social determinants, including socioeconomic factors such as deprivation, overcrowding, and working patterns and conditions,
alongside discrimination and structural violence in the health-care system and society.

Lymphatic filariasis, commonly known as elephantiasis, is a neglected tropical disease. Infection
occurs when filarial parasites are transmitted to humans through mosquitoes. When a mosquito
with infective stage larvae bites a person, the parasites are deposited on the person’s skin from
where ...they enter the body. The larvae then migrate to the lymphatic vessels where they develop
into adult worms in the human lymphatic system.

Après plus de trois ans sans cas, Haïti a signalé le 2 octobre 2022 un ensemble de cas de choléra dans la zone métropolitaine de Port-au-Prince, alors que le pays était sur le point d'être déclaré exempt de choléra.
Cette résurgence du choléra en Haïti survient dans un contexte opérat...ionnel complexe, au milieu d'un environnement socio-politique instable marqué par des blocus, des pénuries de carburant, des activités de bandes criminelles et une insécurité galopante. Les troubles civils et le manque d'accès aux communautés touchées aggravent la crise humanitaire complexe et entravent les efforts de réponse d'urgence.

Psoriasis, which can involve the skin, nails and joints, is a chronic, painful, disfiguring and disabling noncommunicable disease (NCD) for which there is no cure. It negatively impacts on quality of life. Some of those who suffer from the disease develop chronic, inflammatory arthritis (psoriatic a...rthritis) that leads to joint deformations and disability. People with psoriasis are also reported to be at increased risk of developing other serious clinical conditions such as cardiovascular and other NCDs

n light of the potential risk posed by SARS-CoV-2 variants, in January 2021 WHO organized an ad hoc consultation to discuss the development of an R&D agenda in response to existing and emerging SARS-CoV-2 variants.
The key objectives were to identify the critical research questions related to var...iants and agree on a research approach to address them. Six breakout groups covered a range of specific issues related to COVID-19 variants: Epidemiology and mathematical modelling; evolutionary biology; animal models; assays and diagnostics; clinical management and therapeutics; and vaccines.

The Ethiopia Cholera Outbreak - Flash Update #8 reports a worsening cholera crisis, with 11,407 cases and 156 deaths as of June 20, 2023. The outbreak, ongoing since August 2022, has spread across 79 districts in Oromia, Somali, SNNP, and Sidama regions, increasing by 85% since May.
Key challenges ...include contaminated water, insecurity, floods, and a global vaccine shortage, leaving 7.7 million people at risk. Only 15% of affected areas have contained the disease. A vaccination campaign has reached 1.9 million people, and 81 Cholera Treatment Centers (CTCs) have been set up, but funding remains critically low.
The United Nations (OCHA) warns that the upcoming rainy season may worsen the outbreak, requiring urgent intervention.

This document provides the Humanitarian Country Team’s shared understanding of the crisis, including the most pressing
humanitarian needs and the estimated number of people who need assistance. It represents a consolidated evidence base and
helps inform joint strategic response planning.
As ...the conflict in South Sudan enters its fifth year in 2018, the humanitarian crisis has continued to intensify and expand, on a costly trajectory for the country’s people and their outlook on the future. The compounding effects of widespread violence and sustained economic decline have further diminished the capacity of people to face threats to their health, safety and livelihoods. People in need of assistance and protection number 7 million, even as more than 2 million have fled to neighbouring countries.

Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une infection virale entraîne immédiatement une réponse immunit...aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.
