Could a smell test screen people for Covid? Loss of smell and taste is one of the most common symptoms of coronavirus. Scientists are now weighing whether people can be tested for these symptoms to detect the pathogen, if not accurately, but somewhere close to it. A smell test cannot determine whether or not one contracted coronavirus in case of asymptomatic patients. However, a theoretical study, that has not yet been published in a scientific journal, showed that sniff-based tests, if administered sufficiently widely and frequently, might detect enough cases to substantially bring the transmission down. There is no real-world data available yet to support the effectiveness of smell tests as tool for detecting the coronavirus.

Brazil clears AstraZeneca and Chinese vaccines Brazil s health regulator has approved the use of the Astranzenca vaccine and Chinese-made Sinovac against the coronavirus. However, it cautioned that the victory over the virus cannot be achieved only with the jab, but should be accompanied by changes in social behaviour. The approval process has been mired in controversy over lack of data and efficacy of the shot, with the initial trials showing an efficacy rate of 78 per cent, but scientists from biomedical institute pegged the number for “generalised efficacy rate,” which includes cases with very light symptoms, at just 50 per cent.
