(Press-News.org) According to the World Health Organization, a third wave of COVID infections is now all but inevitable in Europe. A COVID tracker developed by IIASA researcher Asjad Naqvi, aims to identify, collect, and collate various official regional datasets for European countries, while also combining and homogenizing the data to help researchers and policymakers explore how the virus spreads.
While many comparisons have been made between the COVID-19 pandemic and similar events in history, one thing sets this pandemic apart from others: the unprecedented amount of knowledge and data that is constantly being generated to understand how the pandemic is unfolding. For a high-income region like Europe, the quality of information made available on a daily basis is exceptionally high compared to the rest of the world. Using this information to make comparisons between different European countries is however not a simple task.
Almost all European countries make COVID-19 data available in the form of maps and trend graphs, but access to data behind these visualizations varies from country to country, with most allowing some form of access to regional data, while others do not release this information publicly. European countries also tend to define regions differently. The European Commission and Eurostat - the statistical office of the European Union - for instance, use homogenous units known as Nomenclature of Territorial Units for Statistics (NUTS), where NUTS 0 denotes countries, NUTS 1 are typically provinces, NUTS 2 are districts, and NUTS 3 are sub-districts. In addition, differences in testing practices and how COVID-19 related hospital admissions and deaths are recorded, further complicate the comparison of data. Lastly, not all European countries are part of the European Union, and therefore are not subject to Eurostat reporting or data sharing requirements.
To overcome some of these challenges, IIASA researcher Asjad Naqvi has developed a COVID-19 tracker that presents data on daily COVID-19 cases at the sub-national level for 26 European countries from January 2020 until the present. Although several innovative datasets that collect unique COVID-19 related information, such as the Oxford COVID-19 Government Response Tracker and the Complexity Science Hub (CSH) Tracker have come onto the scene since the start of the pandemic, Naqvi's tracker aims to identify, collect, and collate various official regional datasets for European countries, while also combining and homogenizing the data at the NUTS 3 or NUTS 2 level. This homogenized dataset makes it possible to explore how the virus spreads in terms of cumulative cases, daily cases, and cases per capita in Europe at a daily resolution.
"One of my aims in developing this tracker was to ensure data transparency, while also making the data consistent and ready for analysis. The paper identifies sources of COVID-19 datasets for 26 European countries and how to access each of them. The data set currently contains over 0.5 million data points at the NUTS 3 or NUTS 2 level," Naqvi explains.
The tracker's data, which is discussed in a new paper published in the journal Scientific Data, can be merged with country or continent-level datasets, such as primary surveys, data from national statistical offices, or data from Eurostat, to conduct comprehensive analyses on the causes and implications of COVID-19. The paper contains a detailed discussion of data sources in each country, including their strengths and weaknesses, and the raw country-level files are provided in an online repository. According to Naqvi, this is one of the very few datasets that has been continuously updated since August 2020 to provide consistent daily information on a regional level for Europe.
The map, for example, clearly illustrates that Germany, on the whole, insulated itself well against the virus and that Sweden and Czechia were particularly hard hit since the start of the pandemic.
Naqvi notes that the tracker can be used for a host of different research questions. It can, for instance, be mapped onto NUTS-level regional data including various economic, demographic, health, tourism, and labor related indicators, some of which also have a monthly or even a weekly frequency. Since data for individual countries are provided, a detailed country-specific analysis can also be done if regional or micro data are available for analysis. Other datasets catalogued on platforms such as the Oxford COVID-19 Supertracker, provides a range of interesting information on various policies put in place by countries during the pandemic. The tracker data can be combined with several innovative global datasets containing NUTS-level information for European countries. As the data for the tracker has a Creative Commons Attribution 4.0 International License (CC-BY), anyone can access it at any time. The data base will continue to be updated regularly until countries stop publishing regional COVID-19 data.

The Institut Pasteur, in partnership with the French National Health Insurance Fund (CNAM), Santé publique France and the Ipsos Social Research Institute, recently presented the results of the ComCor epidemiological study on circumstances and places of infection with the SARS-CoV-2 virus. The aim of the study was to identify the socio-demographic factors, places visited and behaviors associated with a higher risk of infection with SARS-CoV-2. The study contains two parts:
the first part describes the circumstances of infection of index cases diagnosed positive for SARS-CoV-2 during the curfew period, especially when the person considered as the source of infection is known;

PHILADELPHIA - People who struggle with serious mental illnesses are more likely to die early - about 10 to 30 years early - than those without mental illness from any cause. Many factors contribute to this disparity including poor access to care, undetected health conditions and difficulty managing chronic health conditions. Addressing physical illness in those with serious mental illness has been a major challenge. To address this, researchers tested a peer-led intervention called the Bridge that helps patients with mental illness prioritize their health, access health care and develop skills to self-manage their health. The approach showed a 50% reduction in emergency room use for those in ...
University of Otago scientists have opened the door to improved treatment of brain dysfunction which causes psychosis.
Dr Ryan Ward, of the Department of Psychology, says he and a team of researchers have been working on ways to model schizophrenia symptoms in animal models.
"Psychosis is a debilitating aspect of schizophrenia and, while current drugs treat it well, they have horrendous side effects which lead to poor quality of life for patients. Research which can identify specific mechanisms of the dysfunction can provide more precise drug targets for treatment, improving patient ...
WASHINGTON--A new study, published by the North American Menopause Society in the journal Menopause, found a plant-based diet rich in soy reduces moderate-to-severe hot flashes by 84%, from nearly five per day to fewer than one per day. During the 12-week study, nearly 60% of women became totally free of moderate-to-severe hot flashes. Overall hot flashes (including mild ones) decreased by 79%.
The study, called the WAVS trial--the Women's Study for the Alleviation of Vasomotor Symptoms-shows that diet changes can be much more powerful for treating ...

If you didn't have a brain, could you still figure out where you were and navigate your surroundings? Thanks to new research on slime molds, the answer may be "yes." Scientists from the Wyss Institute at Harvard University and the Allen Discovery Center at Tufts University have discovered that a brainless slime mold called Physarum polycephalum uses its body to sense mechanical cues in its surrounding environment, and performs computations similar to what we call "thinking" to decide in which direction to grow based on that information. Unlike previous studies with Physarum, these results were obtained without giving ...

"The solar energy-to-electricity conversion of perovskite solar cells is unbelievably high, around 25%, which is now approaching the performance of the best silicon solar cells," says Professor László Forró at EPFL's School of Basic Sciences. "But their central element is lead, which is a poison; if the solar panel fails, it can wash out into the soil, get into the food chain, and cause serious diseases."
The problem is that in most of the halide perovskites lead can dissolve in water. This water solubility and solubility in other solvents is actually a great advantage, as it makes building perovskite solar panels simpler and inexpensive - another perk along with their ...
