To conduct this study, the researchers took nasal swabs of 145 patients in Chicago, within one week of onset of symptoms. The patients had developed mild to moderate symptoms of the disease. Out of 145 patients, 46 were young children (age less than 5 years), 51 children (age between 5 to 17) and 48 were adults aged between 18 to 65.
WASHINGTON: While initial reports suggested a significant risk of stroke in patients hospitalised with Covid-19, a new study shows a low risk of stroke in patients hospitalised with the disease. Notably, the majority of afflicted patients had existing risk factors, such as high blood pressure and diabetes. These findings provide more clarity about the role Covid-19 plays in causing stroke in a diverse population of the US. The study paper was published in the journal Stroke from Penn Medicine. "While there was an initial concern for a high number of strokes related to Covid-19, that has not been borne out. Importantly, while the risk for stroke in Covid-19 patients is low, it's mostly tied to pre-existing conditions -- so physicians
WASHINGTON: Scientists have known for several months the new coronavirus can become suspended in microdroplets expelled by patients when they speak and breathe, but until now there was no proof that these tiny particles are infectious. A new study by scientists at the University of Nebraska that was uploaded to a medical preprint site this week has shown for the first time that SARS-CoV-2 taken from microdroplets, defined as under five microns, can replicate in lab conditions. This boosts the hypothesis that normal speaking and breathing, not just coughing and sneezing, are responsible for spreading Covid-19 -- and that infectious doses of the virus can travel distances far greater than the six feet (two meters) urged by social distancing guidelines.
NEW DELHI: A new study by the Centre for Science and Environment (CSE) has found that almost 70% of the coal-fired power plants in India may not meet environmental norms (emission standards) by 2022 - five year after their extended deadline - the way they are still not compliant on many critical green issues. The study flagged the overall impact of coal-based plants on environment if they continue to operate without emission control. It said the "deadline should be non-negotiable for plants which came up after the notification". The new emission standards and water discharge norms for coal-based power plants were introduced in 2015. All plants were mandatorily required to comply with the norms by December 2017. This deadline was,
KENSINGTON: The world cut its daily carbon dioxide emissions by 17% at the peak of the pandemic shutdown last month, a new study found. But with life and heat-trapping gas levels inching back toward normal, the brief pollution break will likely be “a drop in the ocean" when it comes to climate change, scientists said. In their study of carbon dioxide emissions during the coronavirus pandemic, an international team of scientists calculated that pollution levels are heading back up — and for the year will end up between 4% and 7% lower than 2019 levels. That's still the biggest annual drop in carbon emissions since World War II. It'll be 7% if the strictest lockdown rules remain all year long
