By Nancy Lapid (Reuters) – The following is a summary of some of the latest scientific studies on the new coronavirus and efforts to find treatments and vaccines for COVID-19, the disease caused by the virus. Vaccination of adults appears to protect children too New data from Israel, where health officials moved quickly to distribute the COVID-19 vaccine from Pfizer Inc (NYSE 🙂 and its partner BioNTech SE (NASDAQ :), suggests that the Adult vaccination also protects the unvaccinated people who live around them. About a third of the 1.95 million members of Maccabi Healthcare Services (NASDAQ 🙂 (MHS), all over the age of 16, had received at least a single dose of vaccine by January 30. When analyzing the results in 223 communities, the researchers found that the number of vaccinated adults increased, infection rates among unvaccinated MHS members in the same community decreased, especially among children. MHS is the second largest health maintenance organization in Israel. “While the observed vaccine-associated protection of the unvaccinated is encouraging, more studies are required to understand whether and how it might support the prospect of herd immunity and disease eradication,” the researchers concluded in the study published on Monday. Wednesday on medRxiv before peer review. .

Four attendees had symptoms similar to COVID-19 that day. Of the 46 coronavirus infections linked to the party, there were 26 cases among clients, three in staff members and 17 “secondary cases” in people infected by them, according to a report published Monday in the Centers for Disease Control and Prevention’s Weekly Morbidity and Mortality Report. Secondary cases included children and residents of long-term care facilities. “The opening event resulted in the closure of a school that affected 650 children (9,100 person-days lost from school) and the hospitalization of a long-term care facility resident with COVID-19, “the researchers said.” These findings demonstrate that opening up environments such as bars, where wearing masks and physical distancing are challenging, can increase the risk of community transmission of SARS-CoV-2, “the researchers said. Businesses should “work with local health officials to promote behaviors and maintain environments that reduce the risk of SARS-CoV-2 transmission and develop strategies to safely reopen to prevent outbreaks in the community, such as modifying designs and operating procedures, “they said. (https: // Congenital heart disease does not worsen COVID-19 risks Adults with congenital heart defects are no more likely than the average person to have severe COVID-19 or to die from it, according to an international study. Risk factors associated with poor outcomes in these people are the same as those associated with poor outcomes in the general public: older age, male gender, history of heart failure, irregular heartbeat, kidney problems, diabetes, and need for extra oxygen earlier from becoming infected with the coronavirus, said study co-author Dr. Jamil Aboulhosn of the UCLA Adult Congenital Heart Center. The researchers analyzed data on 1,044 adults with COVID-19 from 58 congenital heart disease centers around the world. with very complex heart defects did not appear to have an increased risk of severe COVID-19 as long as they did not already have severe signs and symptoms of heart disease, Aboulhosn said, calling the finding “somewhat surprising.” The study was publicly published in the Journal of the American College of Cardiology. (https: // https: // Stroke patients with COVID-19 fare worse Among patients who went to a hospital because they were having a stroke, those who tested positive for COVID-19 were more likely to die there , according to a new study COVID-19 patients were also more likely to have a more serious stroke and another stroke while hospitalized, the researchers reported in the journal Stroke. They studied about 42,000 patients who came to 458 hospitals with an ischemic stroke caused by blockages in the arteries that carry blood to the brain. About 3% of patients tested positive for COVID-19. On average, they got to the hospital as quickly as patients without coronavirus infection. After that , things slowed down. “Probably due to the need to use personal protective equipment and other precautions “by hospital staff, COVID-19 patients took longer to receive anticoagulant treatments that reopened blocked vessels, said study co-author Dr. Gregg Fonarow of the University of California. California, Los Angeles. The study cannot prove that treatment delays caused the worst outcomes. However, Fonarow said, “These findings suggest that stroke protocols need to be further improved to provide more timely diagnosis and treatment for patients with (ischemic stroke) to expedite care while protecting patients. exposure health workers “.
