Prolonged or intermittent social distancing may be necessary even until 2022 to prevent future Covid-19 seasonal outbreaks, a new study has said.Researchers from Harvard University, led by Stephen Kissler, used estimates of seasonality, immunity, and cross-immunity for two betacoronaviruses from time series data from the United States, to inform a model of Covid-19 transmission, Xinhua news agency reported.Recurrent wintertime outbreaks of Covid-19 "will probably occur after the initial, most severe pandemic wave," researchers wrote on in the study 'Projecting the transmission dynamics of SARS-CoV-2 through the postpandemic period', published in the online journal Science.The researchers added that without a vaccine or other interventions, "prolonged or intermittent social distancing may be necessary into 2022."Noting that "a key metric for the success of social distancing is whether critical care capacities are exceeded," the study said that "additional interventions, including ...

A two-week course of an antiviral therapy, started within seven days of experiencing COVID-19 symptoms, may improve clinical recovery of patients and reduce their hospital stay duration, according to the first randomised trial of this triple drug combination. The study, published in the journal The Lancet, involved 127 adults from six public hospitals in Hong Kong, and tested the effectiveness of an antiviral drug combination in reducing the load of the novel coronavirus in their bodies. According to the researchers, including those from the University of Hong Kong, treatment involving combination of the drugs interferon beta-1b, plus the antiviral therapy lopinavir-ritonavir and ribavirin, is better at reducing the viral load than lopinavir-ritonavir alone. They stressed on the need for larger phase 3 trials to examine the effectiveness of this triple combination in critically ill patients, adding that these early findings were only observed in patients with mild to moderate ...
