  3. What’s causing Increases? • The virus survives for longer periods indoors in winter because the relative humidity of indoor air is very low, in comparison to the outside air.

  4. The virus may stay suspended in the air for prolonged periods and thus infect others by being inhaled. The virus droplets can also infect by landing on sensitive body areas such as the eyes, nose, or mouth.

  5. In winter, humans tend to be indoors more and thus have closer contact with each other, which makes it easier for the virus to spread.
