New York, June 9 (IANS) Covid-19 produced more symptoms and complications than seasonal influenza in children, while death was rare among them, revealed a large new study.Early in the pandemic, opinions around the impact of Covid-19 on children and adolescents ranged from it being no more than the common flu to fear of its potential impact on lesser-developed immune systems.To understand, researchers from IDIAP Jordi Gol in Barcelona compared the real-world observational data of more than 242,000 children and adolescents diagnosed with Covid-19, including nearly 10,000 hospitalised youths, to more than 2,000,000 diagnosed with influenza across five countries (France, Germany, South Korea, Spain, and the US) to provide a clearer picture of Covid's impact.The study, published online in the journal Pediatrics, showed that asthma and obesity were the most common comorbidities. There was also a higher prevalence of rare conditions, including congenital malformations, neurodevelopmental disorders, and heart disease, among those hospitalised with Covid-19.Paediatric patients with Covid-19 also showed higher rates of symptoms such as laboured breathing, loss of smell and gastrointestinal symptoms than those with influenza.The most common 30-day complications for hospitalised youths with Covid-19 were hypoxemia and pneumonia, both of which occurred at a higher rate than hospitalised influenza paediatric patients."This study addressed critical questions that were weighing down on both the healthcare community and the general population -- how was Covid-19 impacting our youngest population," said study lead Talita Duarte-Salles, an epidemiologist at IDIAP Jordi Gol in Barcelona"While some last year claimed that Covid-19 was no different than the flu, the real-world evidence we generated through open science showed something quite different. It was a relief to see that fatality was rare, but clearly both complications and symptoms showed the Covid-19 was no flu in children and adolescents," Duarte-Salles added.--IANSrvt/vd
New York, May 22 (IANS) The novel coronavirus responsible for Covid-19 could become little more than a nuisance, causing no more than common cold-like coughs and sniffles within the next decade, say researchers.The team, including Fred Adler from the University of Utah, said this possible future is predicted by mathematical models that incorporate lessons learned from the current pandemic on how our body's immunity changes over time."Over the next decade, the severity of Covid-19 may decrease as populations collectively develop immunity," Adler said.The findings, published in the journal Viruses, suggest that changes in the disease could be driven by adaptations of our immune response rather than by changes in the virus itself.Although SARS-CoV-2 (the sometimes-deadly coronavirus causing Covid-19) is the best-known member of that virus family, other seasonal coronaviruses circulate in the human population -- and they are much more benign.Some evidence indicates that one of these cold-causing relatives might have once been severe, giving rise to the "Russian flu" pandemic in the late 19th century.To test the idea, they built mathematical models incorporating evidence on the body's immune response to SARS-CoV-2 based on few data from the current pandemic.Running several versions of scenarios showed that the three mechanisms in combination set up a situation where an increasing proportion of the population will become predisposed for the mild disease over the long term.The team felt the transformation was significant enough that it needed a new term. In this scenario, SARS-CoV-2 would become "Just Another Seasonal Coronavirus," or JASC for short. "Our next step is comparing our model predictions with the most current disease data to assess which way the pandemic is going as it is happening," Adler noted. --IANS vc/ash
न्यूयॉर्क, 22 मई (आईएएनएस)। कोविड-19 के लिए जिम्मेदार नोवेल कोरोनावायरस विश्व में लोगों के लिए लंबे समय तक सिरदर्द बना रह सकता है। हालांकि विशेषज्ञ ऐसी संभावना जता रहे हैं कि यह लोगों के लिए अगले दशक के अंदर आम सर्दी एवं खांसी जैसे लक्षणों से अधिक कुछ नहीं होगा।
यूटा विश्वविद्यालय के फ्रेड एडलर सहित टीम ने कहा है कि इस संभावित भविष्य की भविष्यवाणी गणितीय मॉडल द्वारा की गई है, जिसमें वर्तमान महामारी से सीखी गई चीजों को शामिल किया गया है कि समय के साथ किस प्रकार से हमारे शरीर की प्रतिरक्षा बदलती है।
एडलर ने कहा, अगले दशक में कोविड-19 की गंभीरता कम हो सकती है, क्योंकि आबादी सामूहिक रूप से प्रतिरक्षा विकसित कर लेगी।
जर्नल वाइरस में प्रकाशित निष्कर्ष बताते हैं कि बीमारी में बदलाव वायरस में बदलाव के बजाय हमारी प्रतिरक्षा प्रतिक्रिया के अनुकूलन से प्रेरित हो सकते हैं।
हालांकि सार्स-सीओवी-2 (कभी-कभी घातक कोरोनावायरस, जो कोविड-19 का कारण बनता है) उस वायरस परिवार का सबसे प्रसिद्ध सदस्य है, जो अन्य मौसमी कोरोनावायरस मानव आबादी में प्रसारित होते हैं।
हालांकि कुछ सबूत इस ओर सभी इशारा करते हैं कि सर्दी के लक्षणों जैसे वायरस के रिश्ते में आने वाला इस प्रकार का फ्लू कई बार गंभीर भी हो सकता है, जिसने 19वीं शताब्दी के अंत में रूसी फ्लू महामारी को जन्म दिया था।
इस विचार का परीक्षण करने के लिए, उन्होंने मौजूदा महामारी के कुछ आंकड़ों के आधार पर सार्स-सीओवी-2 के लिए शरीर की प्रतिरक्षा प्रतिक्रिया पर साक्ष्य को शामिल करते हुए गणितीय मॉडल बनाए।
एडलर ने कहा, हमारा अगला कदम हमारे मॉडल की भविष्यवाणियों की तुलना सबसे मौजूदा बीमारी के आंकड़ों से कर रहा है, ताकि यह आकलन किया जा सके कि महामारी किस दिशा में जा रही है।
Mumbai, May 8 (IANS) Kangana Ranaut on Saturday shared the news that she has tested positive for Covid-19 and has quarantined herself. The actress posted the health update on Instagram, along with a picture that shows her performing Sukhasana."I was feeling tired and weak with slight burning sensation in my eyes for past few days, was hoping to go to Himachal so got my test done yesterday and today the result came I am covid positive," she wrote in the post.The actress urged everyone not to be scared, calling the disease "nothing but a small time flu"."I have quarantined myself, I had no idea this virus is having a party in my body, now that I know I will demolish it, people please don't give anything any power over you, if you are scared it will scare you more, come let's destroy this Covid-19 it is nothing but a small time flu which got too much press and now psyching few people. Har Har Mahadev," she wrote. The news comes days after her Twitter account was suspended, after she posted a series of tweets perceived to be controversial.--IANSdc/vnc
New York - People who received a flu shot last flu season were significantly less likely to test positive for a Covid-19 infection when the pandemic hit, according to a new study.
The study, published in the American Journal of Infection Control, also indicated that those who did test positive for Covid-19 had fewer complications if they received their flu shot.
"It's particularly relevant for vaccine hesitance, and maybe taking the flu shot this year can ease some angst about the new Covid-19 vaccine," said researcher Hofmann, Associate Professor at the University of Michigan.
For the study, the research team included more than 27,000 patients who were tested for a Covid-19 infection in mid-July of 2020.
Of the nearly 13,000 who got a flu shot in the previous year, 4 percent tested positive for Covid-19. Of the 14,000 who hadn't gotten a flu shot, nearly 5 percent tested positive for Covid-19.
The association remained significant after controlling for other variables including ethnicity, race, gender, age, BMI, smoking status, and many comorbid conditions.
The researchers found that people who received their flu shot were also significantly less likely to require hospitalisation, although the researchers didn't find a significant difference in mortality between the two groups.
"It is possible that patients who receive their flu vaccine are also people who are practicing more social distancing and following CDC guidelines. However, it is also plausible that there could be a direct biological effect of the flu vaccine on the immune system relevant for the fight against SARS-CoV-2 virus," the researcher said. (IANS)
New York, Feb 25 (IANS) More US adults reported receiving or planning to receive an influenza vaccination during the 2020-2021 flu season than ever before, a new survey reveals.The survey found that 43.5 per cent of respondents reported having already received a flu vaccination with an additional 13.5 per cent stating they "definitely will get one" and 9.3 per cent stating they "probably will get one." Combined, 66.3 per cent have received or intend to receive an influenza vaccination, the survey revealed."Our survey shows that most Americans have or planned to act on the advice to get a flu vaccination this season," researcher Glen Nowak from the University of Georgia in the US, said in a statement. "Further, these results strongly suggest the US will be crossing an important threshold this flu season, which is over half of US adults getting a flu vaccination," Nowak added.The survey, that involved 1,027 adults, indicated much of the increase in flu vaccine uptake is being driven by people 60 years old and older. A total of 61.5 per cent said they had already received the influenza vaccine in December, with another 12 per cent stating they "would definitely get it" and 5.8 per cent stating they "would probably get it."The respondents came from the National Opinion Research Center's AmeriSpeak panel, which uses a prescreened, nationally representative pool of participants to obtain rapid and projectable survey findings.--IANSvc/bg
