New York (Reuters)-The following is a review of the latest scientific research on the new coronavirus and efforts to find a cure and vaccine for the disease COVID-19 caused by the virus.
Adult vaccinations also seem to protect children
New data from Israel shows that health officials acted quickly to distribute the COVID-19 vaccine from Pfizer and its partner BioNTech. The data shows that adult vaccination can also protect surrounding people who have not been vaccinated.
As of January 30, approximately one-third of the 1.95 million members of Maccabi Healthcare Services (all over 16 years of age) received at least one vaccination. When analyzing the results of 223 communities, the researchers found that as the number of adults vaccinated increased, the infection rate among unvaccinated MHS members in the same community decreased, especially among children. MHS is Israel̵
The researchers concluded in a study published on Wednesday on medRxiv: “While the observed unvaccinated protection associated with the vaccine is encouraging, further research is needed to understand whether and how it can support herd immunity and eradication The outlook for the disease.”.
Bar opening event in Illinois linked to 46 COVID-19 cases
A study in the United States warned that an indoor celebration at a bar in rural Illinois in February resulted in 46 new COVID-19 cases and wider consequences.
On that day, four participants showed symptoms similar to COVID-19. According to a report published in the US Morbidity and Mortality Weekly on Monday, of the 46 coronavirus infections related to the party, 26 were among customers, 3 among staff, and among the infected. There were 17 “secondary cases”. Centers for Disease Prevention and Control. Secondary cases include children and residents of long-term care facilities.
The researchers said: “The spread related to the opening event resulted in the closure of a school, affected 650 children (9,100 school days), and hospitalized a long-term care facility residing in COVID-19.” The researcher said “These findings indicate that in an open environment, such as wearing masks, wearing masks and physically distancing from challenging bars, etc., may increase the risk of SARS-CoV-2 spread in the community.”
They said that companies should “cooperate with local health officials to promote behavior and maintain an environment that reduces the risk of SARS-CoV-2 transmission, and develop strategies for safe reopening to prevent community outbreaks, such as modifying layouts and operating procedures.”
Congenital heart disease does not increase the risk of COVID-19
According to an international study, adults with congenital heart disease are less likely than ordinary people to suffer from severe COVID-19 or die as a result.
The risk factors associated with adverse outcomes in these individuals are the same as those associated with adverse outcomes in the general public-older age, men, history of heart failure, irregular heart rhythm, kidney problems, diabetes, and the need for supplemental oxygen. Co-author of previous studies According to Dr. Jameel Abhosen of the Adult Congenital Heart Disease Center of the University of California, Los Angeles, the virus is infected by the coronavirus.
Researchers analyzed data from 1,044 adults with COVID-19 from 58 congenital heart disease centers around the world. Aboulhosn said that even for people with very complicated heart disease, as long as they do not have serious signs and symptoms of heart disease, they do not seem to increase the risk of severe COVID-19. He called the finding “somewhat surprising.” The research was published in the Journal of the American College of Cardiology.
COVID-19 patients with stroke have a poor prognosis
A new study shows that among patients who go to the hospital due to a stroke, those who test positive for COVID-19 are more likely to die.
Researchers reported in the journal Stroke that during hospitalization, patients with COVID-19 are also more likely to develop a more severe stroke and suffer another stroke. They studied nearly 42,000 patients who arrived at 458 hospitals due to ischemic strokes caused by blockages in arteries that carry blood to the brain. About 3% of patients tested positive for COVID-19. On average, they go to the hospital as quickly as patients without coronavirus infection. After that, things slowed down.
The co-author of the study, Dr. Greg Fornello of the University, said: “Due to the use of personal protective equipment and other preventive measures by hospital staff, patients with COVID-19 need to spend longer time on clot removal treatment. To reopen blocked blood vessels. Los Angeles, California. The study cannot prove that treatment delays lead to worse results. However, Fonarow said: “These findings indicate that it is necessary to further enhance the stroke program in order to provide (ischemic stroke) Patients provide more timely diagnosis and treatment to speed up care while still protecting medical staff from exposure. “
