Shanghai marks COVID milestone, Beijing on edge
By Brenda Goh and Min Zhang
Shanghai records no COVID cases outside quarantine areas
Beijing on tenterhooks, bracing for more restrictions

Infections ease as China starts Labour Day holiday
SHANGHAI/BEIJING, April 30 (Reuters) – Shanghai said on Saturday it had detected no new daily COVID-19 cases outside quarantine areas, marking a milestone in its battle to contain the virus, which has paralysed the city of 25 million and put residents in the capital Beijing on edge.
Streets in Beijing were eerily quiet at the start of a five-day Labour Day break, with residents anxious that authorities would impose further restrictions during a holiday when many typically travel or socialise…
…Beijing will also implement a further two rounds of COVID tests on May 1 and May 3 in its most populous district of Chaoyang, known for its night life, malls and embassies.
The city will halt all restaurant dining between May 1 and 4, an official from the local commerce bureau said, calling for residents to “cook at home”.
Officials have provided no timeline or strategy for returning to some semblance of normality.
Nomura estimates 46 cities are in full or partial lockdowns, affecting 343 million people. Societe Generale estimates that provinces experiencing significant restrictions account for 80% of China’s economic output.
In response to COVID and other headwinds, China will step up policy support for the economy, a top decision-making body of the Communist Party said on Friday, lifting stocks from two-year lows. read more
Shanghai reported 47 COVID-19 deaths for Friday, down from 52 a day earlier. Some have questioned the fatality rate, as many residents have said relatives or friends have died after catching coronavirus as early as March.
Beijing has reported 295 new COVID-19 cases since April 22, the local health authority said, of which 123 cases were found in the Chaoyang district.
Overall, mainland China reported 10,793 daily COVID-19 cases, down from 15,688 new cases a day earlier, the National Health Commission said on Saturday…
Polio this week as of 27 April 2022 Headlines

The Investment Case is the GPEI sister-document to the Polio Eradication Strategy 2022-2026, and outlines the humanitarian and economic benefits of polio eradication. During the event, the Government of Germany, which holds G7 presidency in 2022, announced that the country will co-host a pledging moment for the GPEI Strategy during the 2022 World Health Summit in October. A recording of the virtual event is available online here.

Health Equity in US Latinx Communities
Latinx communities in the US include over 60 million people with a plurality of political beliefs, cultural practices, and wealth. This diversity is also expressed in population health data: some health indicators suggest advantages of Latinx community membership while other data demonstrate inequitable disease burden and maldistribution of environmental and occupational risk. Legacies of colonial conquest of the Americas persist in discrimination and marginalization today and are embodied by members of our Latinx communities.

The theme of this issue of Clinical Pharmacology & Therapeutics (CPT) encompasses neuroscience in the broad sense to include neurology and psychiatry, nonclinical and clinical aspects, novel clinical trial methodologies, and modeling and simulation approaches applicable to central nervous system (CNS) drug development and therapy. While naturally the last two years have been dominated by coronavirus disease 2019 (COVID-19), it is important not to forget that drug development for other indications has not been stopped, albeit many trials were affected in terms of delays in recruitment and collection of clinical data.

Review Article What makes global healthcare partnerships successful? A systematic review Regan Guilfoyle, Alexander D. Morzycki & Abdullah Saleh
Pages: 662-671
Published online: 09 Mar 2021 ABSTRACT
Academic communities are increasingly involved in efforts to address the overwhelming burden of disease in low-middle income countries. There is, however, little research dedicated to understanding the best approach to creating a successful and sustainable global healthcare project. Our objective was to review the shared characteristics of successful healthcare partnerships between high- and low-middle income countries. Two independent reviewers conducted a systematic review. Articles, describing collaborative, healthcare partnerships between a high- and low-middle income countries between 1910 and September 2018, were included. Twenty-six articles were included. The majority of collaborations were initiated by either the host institution or as a joint decision between institutions. The primary goal of these collaborations revolved around medical education/training and curriculum development. Two partnerships, after more than a decade of collaboration, had achieved a self-sustaining programme. Lack of funding was identified as a major barrier to sustainability. Successful global healthcare partnerships require true collaboration and equal participation of all partners. Funding should be secured prior to programme development in anticipation of a minimum 10-year project. A minimum list of guidelines has been proposed to improve the chances of both a successful and sustainable collaboration.

Article Climate change increases cross-species viral transmission risk Colin J. Carlson, et al. Published: 28 April 2022 Abstract
At least 10,000 virus species have the capacity to infect humans, but at present, the vast majority are circulating silently in wild mammals1,2. However, climate and land use change will produce novel opportunities for viral sharing among previously geographically-isolated species of wildlife3,4. In some cases, this will facilitate zoonotic spillover—a mechanistic link between global environmental change and disease emergence. Here, we simulate potential hotspots of future viral sharing, using a phylogeographic model of the mammal-virus network, and projections of geographic range shifts for 3,139 mammal species under climate change and land use scenarios for the year 2070. We predict that species will aggregate in new combinations at high elevations, in biodiversity hotspots, and in areas of high human population density in Asia and Africa, driving the novel cross-species transmission of their viruses an estimated 4,000 times. Because of their unique dispersal capacity, bats account for the majority of novel viral sharing, and are likely to share viruses along evolutionary pathways that will facilitate future emergence in humans. Surprisingly, we find that this ecological transition may already be underway, and holding warming under 2 °C within the century will not reduce future viral sharing. Our findings highlight an urgent need to pair viral surveillance and discovery efforts with biodiversity surveys tracking species’ range shifts, especially in tropical regions that harbor the most zoonoses and are experiencing rapid warming.
