Final answer:
The coronavirus spreads easily due to its novelty, lack of immunity, and respiratory transmission.
Step-by-step explanation:
The possible reason why the coronavirus spreads so easily is that it is a new virus and we do not have antibodies to defend ourselves. Unlike viruses that have been around for thousands of years and caused previous outbreaks, the coronavirus is novel, meaning it is newly emerged and our immune systems have not encountered it before. This lack of immunity allows the virus to spread more easily within populations, as there are fewer barriers to its transmission.
Additionally, the coronavirus is not spread only by touching. It primarily spreads through respiratory droplets when an infected person coughs, sneezes, talks, or breathes out. These droplets can then be inhaled by others nearby or deposited on surfaces and objects, leading to indirect transmission when people touch contaminated surfaces and then touch their face.
Lastly, while the coronavirus is highly contagious, it is not as common as the common cold. The common cold is caused by different types of viruses that have been circulating for a long time and have become endemic in human populations. The coronavirus, on the other hand, is a novel virus that emerged in late 2019 and quickly spread globally.
