NEW YORK (Reuters) – Following is an overview of some of the latest research on the new coronavirus and efforts to find treatments and vaccines for COVID-19, the disease caused by the virus.
Vaccination of adults seems to protect children as well
New data from Israel, where health officials quickly spread the spread of the COVID-19 vaccine from Pfizer and partner BioNTech, suggest that adult vaccination also protects unvaccinated people living around them.
Approximately one-third of Maccabi Healthcare Services’ 1.95 million members – all over the age of 16 – had received at least one vaccine dose by January 30. upwards, the rate of infections among unvaccinated MHS members in the same community has decreased ̵
“Although the observed vaccine-related protection of the unvaccinated is encouraging, further research is needed to see if and how it can support the prospect of herd immunity and disease eradication,” the researchers concluded in a study published Wednesday by medRxiv. peer review.
Illinois Bar Opening Event Related to 46 COVID-19 Cases
An indoor celebration of the opening of a bar in Illinois in February led to 46 new cases of COVID-19 and wider consequences, according to a US study that serves as a warning of how such events could affect local communities.
Four participants had COVID-19-like symptoms that day. Of the party’s 46 coronavirus infections, there are 26 cases among patrons, three among staff members and 17 “secondary cases” in people infected by them, according to a report released Monday in the weekly U.S. Morbidity and Mortality Report. Centers for Disease Control and Prevention. Secondary cases include children and residents of long-term care facilities.
“The broadcast related to the opening event led to the closure of a school affecting 650 children (9,100 lost school days) and the hospitalization of a long-term care facility residing with COVID-19,” the researchers said. “These findings suggest that opening settings such as bars, where wearing masks and physical distancing are challenging, may increase the risk of SARS-CoV-2 transmission from the community,” the researchers said.
Businesses should “work with local health professionals to promote behavior and maintain an environment that reduces the risk of SARS-CoV-2 transmission and develop safe opening strategies to prevent outbreaks in the community, such as relocation and operating procedures, “they said.
Congenital heart disease does not exacerbate the risks of COVID-19
According to an international study, adults with congenital heart defects are no more likely than ordinary people to have severe COVID-19 or die from it.
The risk factors associated with poor outcomes in these individuals 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 supplemental oxygen. before coronavirus infection, said study co-author Dr. Jamil Abulhosn of the UCLA Center for Congenital Heart Disease for Adults.
The researchers analyzed data from 1,044 adults with COVID-19 from 58 congenital heart centers worldwide. Even people with very complex heart defects did not appear to have an increased risk of severe COVID-19, as long as they no longer had severe signs and symptoms of heart disease, Abulhosn said, calling the finding “somewhat surprising.” The study was published in the Journal of the American College of Cardiology.
Stroke patients with COVID-19 have worse results
Among patients who went to the hospital because they had a stroke, those who tested positive for COVID-19 were more likely to die there, a new study shows.
Patients with COVID-19 are also more likely to have a more severe stroke and a new stroke while hospitalized, researchers in the journal Stroke reported. They studied nearly 42,000 patients who arrived in 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 reached the hospital as quickly as patients without a coronavirus infection. Then things slowed down.
“Probably because of the need to use personal protective equipment and other precautions” by hospital staff, patients with COVID-19 need more time to get clots that reopen clogged vessels, said study co-author Dr. Greg. Fonarow of the University of California, Los Angeles. The study cannot prove that delaying treatment has led to worse results. However, Fonarow said, “these findings suggest that stroke protocols need to be further improved to provide more timely diagnosis and treatment of patients with (ischemic stroke) to speed up care while protecting healthcare professionals. from exposure. “
