COVID-19 transmits from one person onto another via respiratory droplets that collect on surfaces, which then spreads when a person touches the contaminated surface and then his mouth, nose or eyes. It can also spread via air if an infected person in your close vicinity sneezed or coughed.
While it is very easy for anyone to spread coronavirus, and equally easy for a person to catch the virus, through the course of the pandemic, it has been seen that only a few people or categories of people are responsible for the massive spread of the virus. Simply put, while some spread the virus to just a few, there are other who are at risk of infecting huge groups, or spread the virus on a community level.
These are what scientists define as ‘superspreaders’ of the virus, or simply, a super emitter of the infection.
While what exactly makes a person a superspreader hasn’t been investigated, but, epidemiologists believe the way a virus or any pathogen spreads is impacted by certain factors- including attributes like the shape of one’s body, and certain behaviours, such as loud talking or breathing fast, appear to have a major role in spreading the disease.
The above-mentioned factors may also determine how some people may be silently spreading the virus onto others.
In fact, the findings of the superspreader group also come at an interesting time, when the newer variants, considered to be more transmissible and many times more infectious are making deadly waves across the world.
According to studies, these are the people who have the highest risk of spreading the disease right now.
