Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019 in China and caused a coronavirus disease 2019 (COVID-19) pandemic. To mitigate the public health, economic and societal impacts of the virus, a vaccine is urgently needed. The development of SARS-CoV-2 vaccines was initiated in early January 2020 when the sequence of the virus
Here is reported the content of the Correspondence We read with great interest the results presented by Denis Logunov andcolleagues on the safety and efficacy of a Russian vaccine for COVID-19. Although the study results are potentially significant, we have severalconcerns, which, due to the accelerated distribution of the vaccine to thepopulation, we described in
A standard test that assesses variations in red blood cell volume can identify hospitalized patients with COVID-19 who are at elevated risk of becoming critically ill and succumbing to the disease, according to newly published research led by a team of Harvard Medical School investigators at Massachusetts General Hospital’s Center for Systems Biology. The findings, described in JAMA Network
Research in England shows a dangerous relationship between the viruses that cause both diseases; for those in the ICU with co-infection, the risk of death is 6.33 times higher. People infected at the same time by the new coronavirus and the flu virus are twice as likely to die than those infected by Sars-Cov-2 alone . This is the
Two categories of disease are interacting within specific populations—infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and an array of non-communicable diseases (NCDs). These conditions are clustering within social groups according to patterns of inequality deeply embedded in our societies. The aggregation of these diseases on a background of social and economic disparity exacerbates
Early in the pandemic, other clinicians noted that even some patients who didn’t have preexisting heart conditions experienced cardiovascular damage while fighting COVID-19 infections, pointing to a possible causative link. Researchers had found, for example, that 8–12 percent of hospitalized COVID-19 patients had elevated levels of muscle contraction–regulating proteins called troponins—a sign of heart damage—and that these
Currently, no Food and Drug Administration (FDA)-approved therapeutics exist for coronavirus disease 2019 (COVID-19). In this context, the pandemic has put considerable pressure on health care providers to prescribe treatments despite limited information about their safety and efficacy. This pressure has exacerbated the tension between the importance of practicing evidence-based medicine and the urgency of
New findings by scientists at the National Institutes of Health and their collaborators help explain why some people with COVID-19 develop severe disease. The findings also may provide the first molecular explanation for why more men than women die from COVID-19. The researchers found that more than 10% of people who develop severe COVID-19 have
Children were less likely than adults to acquire a COVID-19 infection from an index case, a meta-analysis found. Across 32 contact tracing or population testing studies comparing SARS-CoV-2 prevalence in children and adults, children younger than 14 were less likely to be infected from an index case overall (odds ratio 0.56, 95% CI 0.37-0.85), and
COVID-19 appears to have significant extrapulmonary complications affecting multiple organ systems. Critically ill patients with COVID-19 oftendevelop gastrointestinal complications during their hospital stay, including bowel ischemia, transaminitis, gastrointestinal bleeding, pancreatitis, Ogilvie syndrome, and severe ileus. Whether the high incidence of gastrointestinal complications is a manifestation of critical illness in general or is specific to COVID-19
