A group of 16 scientists has written an open letter to Dr Richard Horton, editor of The Lancet and authors of the Russia’s Sputnik V novel coronavirus vaccine trial paper,…
By stating that “all individuals who wish to get themselves tested” are eligible for tests on demand, the ICMR is theoretically making all of India’s 1.3 billion people eligible for a test and also demand a test repeatedly without an upper limit, even when the country does not have the capacity to undertake such a massive exercise. Clearly, the latest advisory is over ambitious and has been framed without much application of mind.
Using the cycle threshold (Ct) values to infer COVID-19 disease severity or infectiousness may be problematic. Cycle threshold values can be suggestive of the amount of virus in an infected person but there is no reliable way of correlating the Ct value with COVID-19 disease severity or infectiousness. But largely, when the Ct value is over 35, a person is unlikely to be infectious. There are many variables that can alter the Ct value of a sample.
A single person travelling in an air-conditioned bus along with 67 other passengers in Zhejiang province in eastern China on a 100-minute round trip spread the virus to 23 people. With India’s Unlock 4 guidelines permitting metro rail services operation from September 7 outside the containment zones, how safe will metro rides be.
Russia’s Sputnik V vaccines for novel coronavirus have been found to be safe for a period of 42 days and capable of inducing antibody responses in all the 42 participants…
IGIB researchers have been able to detect novel coronavirus using mass spectrometer. The detection is based on the presence of two unique peptides of the virus. Sensitivity is 95% and…
Pre-existing memory T cells that cross-react with SARS-CoV-2 may only reduce COVID-19 severity cannot prevent infection. The memory T cells are extremely unlikely to prevent SARS-CoV-2 infections. That is just…
Using genome sequencing researchers at Reno School of Medicine, University of Nevada have confirmed a case of coronavirus reinfection. Unlike the first reported case of confirmed reinfection in Hong Kong…
