L'OMS a développé une définition de cas clinique de l'état post COVID-19 par la méthodologie Delphi qui comprend 12 domaines, disponible pour une utilisation dans tous les contextes. Cette première version a été élaborée par des patients, des chercheurs et d'autres personnes, représentant... toutes les Régions de l'OMS, étant entendu que la définition peut changer à mesure que de nouvelles preuves apparaissent et que notre compréhension des conséquences de la COVID-19 continue d'évoluer.
L'état post COVID-19 survient chez les personnes ayant des antécédents d'infection probable ou confirmée par le CoV-2 du SRAS, généralement 3 mois après l'apparition de symptômes qui durent au moins 2 mois et ne peuvent être expliqués par un autre diagnostic. Les symptômes courants comprennent la fatigue, l'essoufflement, le dysfonctionnement cognitif mais aussi d'autres et ont généralement un impact sur le fonctionnement quotidien. Les symptômes peuvent être d'apparition récente après le rétablissement initial d'un épisode aigu de COVID-19 ou persister depuis la maladie initiale. Les symptômes peuvent également fluctuer ou rechuter au fil du temps.

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition...al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

How has the pandemic impacted the fight against Polio? How has the polio infrastructure helped the fight against COVID-19? Why is it important that the world doesn’t take its eyes off polio? Sona Bari explains in Science in 5 this week.
The HIV drug resistance report 2021 summarizes findings from 38 countries that had finalized the surveys by the time of this report and shared data with WHO.
Pretreatment HIVDR to non-nucleoside reverse-transcriptase inhibitors (NNRTI) can affect more than 10% of adults starting therapy and is fo...und up to 3 times more often in people who had previous exposure to antiretroviral drugs. In addition, nearly half of infants newly diagnosed with HIV has HIVDR to NNRTI before initiating treatment.The high levels of observed NNRTI pretreatment HIVDR among emphasize the need to fast-track the transition to WHO-recommended dolutegravir-based ART.

WHO and Psyon Games have joined forces to launch a new tower defense game called the Antidote COVID-19 to turn complex, scientific information into a fun learning experience. During the course of the game, players will learn about their immune system, pathogens, vaccines and how to protect themselve...s from COVID-19.
The game comes at a critical point of the pandemic where misinformation is hindering COVID-19 vaccine acceptance and adherence to other public health measures due to fear, mistrust and doubt. By putting players in the driver’s seat, the game urges everyone to play a role in fighting harmful misinformation online, and learning and sharing the facts from trusted sources of information.
The game starts just before the pandemic begins. The player is recruited to halt the spread of SARS-COV-2, the virus that causes COVID-19, by developing vaccines and helping the human immune system fight off the virus. Based on real events, this online adventure takes the player to the frontline of science, ultimately providing lifesaving information in the palms of their hands.
