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.

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.

Patients with suspected coronavirus disease 2019 (COVID-19) can infect others at any time, including during transfer and transport. COVID-19 is a new infectious disease that requires contact and droplet precautions; lapses in infection prevention and control (IPC) can easily happen at vulnerable mom...ents such as during transfer. This guide aims to identify key steps to prepare the community and health system response to ensure IPC is maintained during transfer and transport. This guide is intended for personnel involved in coordinating and performing transfer and transport of patients with suspected COVID-19 requiring hospital care.

Primary care can play a significant role in the COVID-19 response by differentiating patients with respiratory symptoms from those with COVID-19, making an early diagnosis, helping vulnerable people cope with their anxiety about the virus, and reducing the demand for hospital services. This document... provides national and subnational health managers, as well as staff at primary care facilities, with interim guidance on timely, effective and safe supportive management of patients with suspected and confirmed COVID-19 at the primary care level; and delivery of essential health services at the primary care level during the COVID-19 outbreak

Efficient triage of patients with COVID-19 at all health facility levels (primary, secondary and tertiary) will help the national response planning and case management system cope with patient influx, direct necessary medical resources to efficiently support the critically ill and protect the safety... of health-care workers. The objective of this algorithm is to give overall guidance for the triage and referral of symptomatic COVID-19 patients. Intended for use by ministries of health, hospital administrators and health workers involved in response planning for COVID-19 and/or patient triage, management and referral, this algorithm provides a general framework to be adapted to local health systems in countries.

In response to the COVID-19 outbreak, this guidance provides information on infection and prevention control (IPC) for older people, their friends and families, carers, and healthcare providers. Anyone who manages, works, volunteers or provides care at any type of facilities where older people recei...ve care at (long-term care facilities, non-acute care facilities, and home care services), should practice strict IPC to prevent and control COVID-19 outbreaks. It has been observed in different countries that older people have higher case-fatality rate compared to other age groups. Therefore, it is especially important to implement and follow IPC measures at facilities, homes, and other venues that older people frequent.

People living with HIV depend on life-saving antiretroviral therapy (ART) and access to ART must be maintained during periods of travel restrictions and lockdowns resulting from the COVID-19 pandemic. The Information note on HIV and COVID-19 addresses common concerns people living with HIV have rega...rding the risks of COVID-19 and how to minimize them. For HIV programme managers and health facilities providing HIV services, it identifies key points related to ensuring uninterrupted provision of ART, while protecting clients and staff from the risk of infection with the SARS-CoV-2 virus.

People with underlying noncommunicable diseases (NCDs) such as hypertension, diabetes, cardiovascular disease, chronic respiratory disease and cancer have a high risk for developing severe and even fatal COVID-19. It is important for them to strictly follow basic protective measures and make sure th...eir chronic diseases are well managed. However, pandemics cripple health systems and compromise provision routine medical care. This technical note gives general guidance to people living with NCDs, their caregivers and family members, the public, health programme managers and health-care workers on how to reduce risks of a COVID-19 infection and maintain care for people living with NCDs during the outbreak.

Severe cases of COVID-19 are associated with rehabilitation needs related to the consequences of ventilatory support, and prolonged immobilization and bed rest. These may include: − Impaired lung function; − Physical deconditioning and muscle weakness; − Delirium and other cognitive impairment...s; − Impaired swallow and communication; and − Mental health disorders and psychosocial support needs. − Rehabilitation needs may be amplified by underlying health conditions and decrements in health associated with ageing, − Rehabilitation professionals play an important role in facilitating early discharge, which is especially critical in the context of hospital bed shortages. − Rehabilitation needs of people with severe COVID-19 exist during the acute, sub-acute and long-term phases of care; rehabilitation professionals should be positioned in ICUs, hospital wards, stepdown facilities and in the community. − Particularly in the acute phase, rehabilitation interventions for patients with severe COVID-19 requiring ventilatory support generally require a particular skill-set acquired through specialist training.

Mothers and healthcare workers who support them have many questions and concerns about whether it is safe for mothers with confirmed or suspected COVID-19 to be close to and breastfeed their babies during the pandemic.
To address their questions, WHO has released a list of Frequently asked question...s: Breastfeeding and COVID-19. The FAQ complements the WHO interim guidance: Clinical management of severe acute respiratory infection when COVID-19 is suspected and draws upon other WHO recommendations on infant and young child feeding.
The FAQs aim to provide information to healthcare workers supporting mothers and families in maternity services and community settings, and communicate how the interim guidance should be implemented. Additionally, the FAQs provide information about the protective effects of breastfeeding and skin-to-skin contact, and the harmful effects of inappropriate use of infant formula milk.
