While transmission of the novel coronavirus as small aerosol particles is more significant in summer, direct contact with respiratory droplets may be more pronounced in the winter months, according to a new research.<br />”&nbsp;<br />”The modelling study, published in the journal Nano Letters, also noted that the currently followed physical distancing guidelines are inadequate in curbing the transmission of COVID-19.<br />”&nbsp;<br />”It is found that in most situations, respiratory droplets travel longer distances than the 6-foot social distance recommended by the CDC,&quot; said Yanying Zhu, a co-author of the study from the University of California (UC) Santa Barbara in the US.<br />”&nbsp;<br />”&nbsp;In indoor environments such as walk-in refrigerators and coolers, where temperatures are low and humidity is high to keep fresh meat and produce from losing water in storage, the scientists said this effect is increased with the droplets transmitting to distances of up to 6 metres (19.7 feet) before falling to the ground.<br />”&nbsp;<br />”<span style="color: #222222;">They said in such environments, the virus is particularly persistent, remaining infectious from several minutes to longer than a day in various environments. At the opposite extreme, in hot and dry places, the researchers said respiratory droplets evaporate more easily.&nbsp;</span><br />
