“SARS Cov 2 is a respiratory virus and the transmission of respiratory viruses is known to increase during the colder weather. Respiratory viruses thrive better in cold weather and low humidity conditions. There is another fact that needs to be kept in mind. During winter, there is a tendency of overcrowding in residential dwellings which may increase transmission… So in Indian context, it would not be wrong to assume that the winter season may see an increase in the number of cases,” Central health minister Dr. Harsh Vardhan said, addressing his weekly social media interaction programme Sunday Samvaad. “Hence, we are emphasising on the precautionary measures which are easy to follow. No need to fear and shudder. Wear the mask and maintain social distancing. Prevention is better than cure,” the minister said, sounding a note of caution.
